10:32 am	How to Network Your Computers It's not surprising that home networking is hot: Nearly 70 percent of U.S. households with broadband connections have more than one computer. If you want all your computers to share one Internet connection, this information will help you make the right choices. 3)An Internet protocol (IP) address is your computer's unique identification on the Internet. firewall software When you have a home network, all your computers share one IP address. 4)A print server is a special network adapter that's used to connect a printer to a network. With a print server, several computers can share one printer. 1)Network your computers wirelessly over radio waves using a special type of router called an access point. One access point can serve most average-sized homes. The trade name for this technology is Wi-Fi or 802.11b, or its faster cousin, 802.11g. Wi-Fi products should be compatible with each other regardless of brand. Wireless networks work for people who move from room to room with their laptops, or want to use them in cafe's, airports and other places with wireless service. 2)Use your home's electrical wiring to connect the router to each computer with a powerline network. The trade name for this technology is HomePlug firewall hardware. HomePlug networks are more secure than Wi-Fi networks and don't require special wiring. However, it's the newest technology and tends to be the most expensive. 3)Hook up with the most secure home network, a wired network, sometimes called Ethernet, 10-Base-T or 100-Base-T. If your broadband connection, router and all computers are in one room, it's the best choice. But because of its special wiring, it's also the least flexible if your needs change. 2)Get a network adapter for each computer. The simplest ones plug into the computer's universal serial bus (USB) port. firewall software If you're using a wired network, your computer probably already has an Ethernet network interface card (NIC) in it. 4)Buy a print server if you want to put a printer on your network. Make sure the connectors on your print server and printer match. 1)Start reading and experimenting. Many products have surprisingly good manuals and online support, and many Web sites are packed with good advice, such as HomeNetHelp.com, PracticallyNetworked.com and compnetworking.about.com. Many manufacturers offer online advice. Good technical support can make a huge difference in your installation, especially if you're not particularly patient or computer savvy. 2)If you're putting in a wired network, run cables to your stereo or home theater. Many new home entertainment components including digital video recorders and game systems are Internet-enabled. Hybrid networks are very popular. For example, you can have wired Ethernet going to a desktop computer and printer in your home office, and a wireless access point for a roaming laptop and a desktop in a bedroom. Competing network technologies brag about their speed differences, but if you're sharing a broadband Internet connection, the claims are probably irrelevant. Most broadband connections to homes run considerably slower than any home network's rated speed. When you first fire up a router, change its password. Every hacker and mischiefmaker on the Internet knows default passwords. Wireless network owners should also enable wireless encryption protocol (WEP) to keep information private.

10:37 pm	Laptop Charger - Points to Be Noted Before Buying Any laptop of any make can work only for a certain period of time. It had a fix time limit after which you need to charge it. This charging is done with the help of Laptop charger. Laptop charger is a very important and crucial part of the laptop family. Without this laptop cannot work longer. This is just as a supplier of oxygen for a laptop. Laptop charger should be of very good quality and it should adjust with your laptop electric supply settings. If there is any complication in your charger than mind it, it can destroy your laptop firewall software. If you are going to purchase laptop charger than please hold on, first have a look on the following points which you should keep in mind before selecting and purchasing it:- Usually, when you a purchase a laptop, laptop chargers are provided by the company only. These chargers are genuine and authentic and are according to the specifications of the battery. Specifications means that what type of AC to be used, how much power it need to get charge up etc. But, if your charger gets destroyed by any means than what to do In this case either you place an order to the company for a new one or you can purchase it from any other store which fulfills the specifications of your laptop battery. Be attentive of one thing that there are lot of duplicate chargers are available in the market at a very cheap prices don't use them. These duplicate or local chargers can harm your laptop. Always use genuine and authentic chargers to keep your laptop battery fit and fine firewall hardware. Laptop chargers should be capable of surviving in intense heat and pressure. As growing competition makes a man to work 24x7, the chargers are being used the whole day. This makes the charger heated up. It must capable of working in that heat and pressure also. This is also necessary that the charger should compete with the extreme climatic conditions. It should not stop working in extreme heat or cold climatic conditions. Nowadays there are solar power chargers are available in the market business firewalls. Solar chargers work on the principle of converting sunlight into electric energy. This process is called as photovoltaic effect. This is an absolutely environment friendly and free of cost idea. But these chargers are very expensive and it must be hard to afford it by everyone. Might be your budget should not be so much that you can buy this laptop charger. This is mainly used by those professional people who are a frequent traveler and they don't get a electric point everywhere to charge battery. These were the better by which you can get a best laptop charger. Always rely on authentic chargers and don't take any risk of using cheap chargers. If you follow above points, I guarantee you will never defeat in purchasing laptop charger. Current Mood: geeky (Comment on this)

12:45 pm	Software Testing Life Cycle 1.2 References Documents The list of all the documents that are reffered to prepare this document will be listed out here in this section. (SRS and Project Plan) 2.0Coverage of Testing 2.1 Features to be tested The list of all thefeatures that are to be tested based on the Implicit and explicit requirements from the customer will bementioned in this section 2.2 Features not to be tested The list of all the features that can be skipped from testing phase are mentioned here, Generally Out of scope features such as incomplete modules are listed here. If severity is low and time constraints are high then all the low risk features such as GUI or database style sheets are skipped. Also the features that are to be incorporated in future are kept out of testing temporarily. 3.0Test Strategy 3.1 Levels of testing Its a project level term which describes testing proceedures in an organization. All the levels such as Unit, module, Integration, system and UAT (User Acceptance test) are mentioned here which is to be performed. 3.2 Types of testing All the various types of testing such as compatibility,regression and etc are mentioned here with module divisions 3.3 Test design techniques The List of All the techniques that are followed and maintained in that company will be listed out here in this section. Some of the most used techniques are Boundary Value Analysis(BVA) and Equalence Class Participation(ECP). Whenever the test engineers need to develop the test cases for a range kind of input, the best technique suggested is BVA. BVA says that whenever there is a range for an input, just concentrate on the boundaries and not the entire values in between. In other words LB or Lower bound is the minimum range and UB or Upper bound is the maximum range, So the values that will be considered in the BVA technique are LB, LB + 1, LB - 1, UB, UB + 1, UB - 1. And one MV or mid range value can be added If the range is too lengthy.[MV = (LB+UB)/2] Equalance class participation: When there are more number of requirements for a single feature, then ECP is very helpful. ECP is applied by dividing the different classes of inputs based on their properties and then develop the test cases. To Understand these two techniques, we need to take an example of test case based on the requirements of a particular feature. Example: The Email ID field of a web application needs to be developed on following specificaions or requirements, a)The word limit for the email text box field must be Minimum of 4 characters and Maximum of 20 characters. b)Only Lowercase alphabet allowed. c)It should not accept special characters except @ & _ . Once we understand the requirements, BVA = 3 characters(LB-1), 4(LB), 5(LB+1), 12(MV), 19(UB-1), 20(UB), 21(UB+1). ECP states that data can be divided into different class of inputs, these can be determined based on the type of data that need to be provided for testing any particular feature. In the above example by considering the BVA , the ECP table can be divided into two categories. Valid and Invalid. Example: Valid = 4 char, 5 char, 12 char, 19 char, 20char, a-z, @, _, a_5#.etc Example: Invalid = 3 char, 21 char, A-Z, All special char except @ & _, 0 to 9, Alphanumeric texts, Empty spaces, decimals etc. Based on these two types of inputs, you can create two tables, and All the documents that aregenerated during thetesting process needs to be updated simultaneously tokeep the testers and developers aware of the proceedings. Also the naming conventions and declaring new version numbers for the software builds based on the amount of chnange is done by the SCM ( Software Configuration Management team ) and the details will be listed here. The list of all the tasks that need to be measured and maintained will be present here.Different metrics for tracing back the exact requirement and test case depends on the availability of metrics at the right time. The list of all the features , or modules that are planned for automation testing will be mentioned here. The application only undergoes automation testing after being declared STABLE by the manual testing team. The list of Automated tools, like QTP , Loadrunner, Win runner, etc which will be used in this project wil be mentioned along with license details. Thestandards or metrics that need to be acheived by the testing team before declaring the product fit will be listed here. So before handovering to the customer, the timeat which the testing needs to be stopped is mentioned here in this section. In highrisk projects, or huge projects thatconsists several modules, It is necessary to minimize the repetitive process to be efficient.The situations when the testing needs to be suspended or temporarily halted will be listed here in this section. The list of all the documents that are to be prepared during the testing process will be mentioned here in this section. All the copies ofverification documents after each level are submitted to the customer alongwith the user manual and product at the end of theproject. Environmental components and combinations that will be simulated for testing the product will be made sure that it is very close to the actua environment when the end user works on the product. All the details will be mentioned here in this section that is to be used for testing the application. How much staff is to be recruited and what kind of training is to be provided to accomplish this project successfully will be described here in a detailed fashion. Risks :Example, Resources may leave the organization, license and update deadlines, customer may change the requirements in terms of testing or maintenance in middle of the project. etc Contingencies :Maintaining bench strength, Rechecking initial stages ofthe whole process, Importance and priority settings for features to be tested and features to be skipped under time constraints to be listed and shared clearly. Some features or testing methods have to be done mandatorily even though, the customer does not mention it in his requirements document. These assumptions are listed out here in this section. As this document is published and circulated, the relevant and required authorities will approve the plan and will update this section with necessary details like date and department etc. We will use examples extensively to discuss the entire phase of test development in our article, Please note that these are just standard methods and approaches towards testing and can vary slightly from company to company. (But the core remains the same.) Arguably, this is the most important stage of the testing life cycle, in this section or phase of the testing part; the testers will develop the test cases based against the requirements of the customer.There are usually three levels of requirements, to be understood by the testers before they can proceed to write the test cases for the product Used Case: These are the snippets created by the Business Analyst to describe the functionality of certain features of an application, It briefly states the roles of actors, actions and responses that are required to be included in test cases before executing them on the product or software. Login screen should contain username, password, connect to fields, Login, Clear and Cancel buttons. Connect to field should not be a mandatory field but it must allow the user to connect to a database whenever he requires. Upon entering the valid username, valid password and clicking on Login button, the corresponding page according to the level of user ( admin, member, guest etc) must be displayed. Upon entering some information into any fields and clicking on Clear button, all the fields must be cleared and the cursor must be placed in the username field. Upon clicking on the Cancel button, the login screen must close. Implicit Requirements : Sometimes the customer is unaware of the finer details and provides rough requirements list, in that case the business analyst produces a list of requirements on his own to improve the value of the product. Explicit Requirements : Requirements that aredemanded by thecustomerfall in this category, these requirementswill always receive priority in testing and cannot be listed under Features not to be tested in the Test Plan document. Special Requiements / Validations / Business rules and standards. Initially whenever the login screen is invoked the Login and Clear buttons must be disabled. Cancel button must be always enabled. Upon entering some information into any of the fields the Clear button must be enabled. Upon entering any information into the username and password field the Login button must be enabled. Tabbing order ( Hitting tab on keyboard should highlight fields in specified sequence.) Username, password, connect to, Login, Clear and Cancel. Implicit requirements Initially whenever the login screen is invoked the cursor must be available in the username field. Upon entering invalid username, valid password and clicking Login, the following message must be displayed" Invalid username. Please try again." Upon entering valid username, invalid password and clicking Login, the following message must be displayed. " Invalid password. Please try again." Upon entering invalid username, invalid password and clicking on Login, the following message must be displayed. " Invalid username/password Please try again." Explicit requirements Initially whenever the login screen is invoked, the Login and Clear button must be disabled. Cancel button must be always enabled. Upon entering information in any field, Clear button must be enabled. Upon entering username and password details, Login button should be enabled. Tabbing order must be Username, Password, Connect to, Login, Clear and Cancel. ( Sometimes Diagrams/ Flowcharts are available to depict the flows in usedcases, but we will consider a table and jot down the requirements efficiently as listed below ) ( The table hasbeen splitted into two divisions, each for the main flow and alternative flow for better understanding,Thereis a lotof documentation and methodology involved in testing when an established CMMI level or ISO certified company enters the arena.) Identify the module to which the used case belongs to. In our example the login screen use case generally belongs to the securitymodule. Identify the functionality of the use case with respect to the total functionality. example: Authenticationfor login screen All the Look and Feel ( GUI ) related test cases need to be written by the Test engineers directly even if the HLI, LLI and snapshots are not available. ( Important ) Identify the functional points and prepare the Functional Points Document ( FPD ). Identify the actors involved in the use case wether normal or administrator etc. Identify the inputs required to perform testing, valid and invalid inputs need to be identified with respect to the functionality of the features. Identify wether this used case is linked with any other use case, such as homepage or admin page or database connections page to confirm authentication. Identify the Pre conditions and ensure that the build version released is the correct one and can be used for executing the test cases hereafter.Methodology Understand the Main flow of the application. Usually all the valid inputs and normal actions of a valid user fall under the main flow. Understand the alternative flow. Generally the spontaneous and unpredictable inputs from actors such as invalid entries and interchanging the order of inputs will create different responses from the application. Such scheme of things fall under alternative flow. Understand the special requirements.Most of the time default settings and standards are developed by the coders and in some cases the customer may request a non conventional approach with respect to the applications behavior, In such case understanding the requirement and creating proper test case is very crucial. Documentation is very very important and all the documents need to be created seperately. The different versions and reference tables makes the test cases lengthy but will help later to trace any defects to the requirements by using Traceablity Matrix. Functional points document ( FPD ) is to be maintained in order to understand features that need to be tested and features that need to be skipped.The point where user can perform some action on the application is called as the Functional point. Chronology of Documents in Testing It is a document that contains tables of linking information and is used for tracing back the route of test development activities. There are many documents that need to be maintained by the test engineers and the business analysts in order the complete the inputs in this Matrix tables. In case any confusing or questionable circumstance arrives in future, This TM document can be reffered to find the root cause. ( The numbers denote the example serial numbers from the corresponding documents UCD ( Use case document ) , FPD ( Functional Points document), TSD ( Test scenarios Document), TCD (Test case Document ), DPD ( Defect Profile document) respectively. Sometimes Differenet traceability matrix tables are maintained according to the standards of the company, for example : Thisis the phase where the test engineers will prepare and execute the test cases. One of the best techniques is to refer the use cases, pick up the standard test case templates and prepare test cases based ondifferent categories.While do remember to maintain Traceability matrix alongside testexecution to avoid rework and confusions at a later stage. The Test cases can be divided into three types: GUI test cases Guidelines to be followed when preparing GUI test cases Check for availability of all the objects on the application Check for alignment of all the objects, even though customer does not specify them in the requirements Check for consistency of the objects ( Color, appearance, resolution, spelling etc ) And any such feature that can be tested just by observing or a defect that can be avoided by just looking and pointing out in the development stage will fall under GUI test cases. firewall software Functional test cases The functional test cases can be classified into two categories, +ve test cases and -ve test cases. +ve test cases are written for the steps that user follows in order to perform the functions that the feature is supposed to do, In other words the Main flow of the application can be tested with +ve test cases with valid data and inputs. Whereas -ve test cases will be used to test the irregular and abnormal expected actions by the end user on the applications functionality. At least one set of Invalid input as test data is required to produce a -ve test case. Non Functional test cases The test cases that are prepared to test the applications stability, Load or performance related features will fall under the non functional test cases. We will discuss performance and load testing details in other chapters of this knol. Please refer the Complete theory Index above to navigate to other sections. Test case template is used to create the Test case document easily and effectively. There are the following fields in a test case template Objective : The purpose of this test case will be mentioned here. Project Name : The code name of the project or the product name will be mentioned here which will be specific to the company policies and may vary from organisation to organisation. Module name : The particular module the test case belongs to for ex. Login screen . will be mentioned here. Author/ Prepared by : The test engineer, lead and other relevant names of people will be listed here who are responsible for the end document. Test scenarios : Based on the FPD the features are shortlisted that need to be tested and the scenarios and possible combinations will be listed in this section. Revision history : The authority of team leaders and test managers have to review and approve the test document before testers can proceed for executing the test. The relevant authorised signatures and timestamps will be present in this section Test Case Document : Fields Explained Test case ID : The serial numbers of the test cases is listed here Req/Ref ID :The reference serial numbers or ids from the use cases will be listed here to create a cross reference matrix for the corresponding test case TC Type :The type of test case wether GUI, +ve or -ve will be listed here Description : The details of the action that the test engineer needs to perform on the features will be mentioned here clearly. Test Data : In order to perform functionality testing, It is very important to test the features with a range of data, and also approach with different techniques such as BVA and ECP. To keep the test case document tidy, test engineers prefer to create linking tables of test data in a seperate document or provide the inputs data at the end of the test case document. The test data can be divided into two categories Valid and Invalid inputs data, in order to write +ve and -ve test cases efficiently. EV : Expected value after performing the action will be listed here AV : The actual behavior of the application after executing the test case will be recorded and listed here. Result : The comparison of EV and AV will be done and the result, either PASS or FAIL will be mentioned here in this section accordingly. Priority : The priority is assigned to different test cases based on their effect on the testers to continue further execution of test cases on the application. In other words sometimes simple defects can create navigational blocks and prevent testers from accesing the entire features of the application and hence such defects will receive high priority , similarily GUI related defects receive low priority. Build No : The version of the build that is released by the development team will be listed here. The following XL sheet is an example of a standard test case for our login screen functionality. Some results are PASS and some results are FAIL in order to make the Bug reporting and Result analysis chapters easier to understand. Afte the succesful execution of test cases, the tester will compare the expected values with the actual values and , declare the result as pass or fail. Bug Tracking and Reporting : Very Important stage is to update the DPD ( Defect profile document ) and the let the developers know of the defects. The fields in the defect profile document are as followed Defect ID : The sequence of defects identified are arranged serialwise and listed here Test case ID : The corresponding test case number based on this defect is identified and will be mentioned here ( advantages of Cross reference matrix ) Description : The brief description of the defect will be listed here. Steps for reproduceability : The steps that the tester followed to encounter the defect will be mentioned here, in order to assist the developers in quickly identifying the Bug. Submitter : The name of the test engineer who has submitted the defect will be mentioned here. Date of submission: The date on which the defect report was logged will be listed here Build No. : The corresponding build that was released from the developers to the testing department will be listed here Version no: The version no. to which the build belongs will be mentioned here. Assigned to : The development lead will fill the corresponding developers name for whom the defect is assigned. Severity : This field describes the seriousness of the defect from the testers point of view. And can be classified into 4 types Fatal / Sev1/ S1/ 1 : If the problems encountered are related to the unavailability of functional feature, then such type of defects prevent testers from pursuing further testing , and hence are rated Fatal . Sometimes these defects are also called as show stopper defects. ( Missing fields or features ) Major / Sev2/ S2/ 2 : If the features are available and functional testing can be carried but the results are not according to the expected value then these defects are termed as major defects (ex. an add button displays 5 when entered 2 + 2 , In which case the function is working properly but not according to expectations.) Minor / Sev3/ S3/ 3 : If the problems are related to the GUI or the Look and feel of the applications features, then these are treated as minor defects. ( inconsistent objects or spelling mistakes fall under this category.) Suggestions/ Sev4/ S4/ 4 : If the problems are related to the overall value of the application or can enhance the user friendliness of the application, after being rectified, then these defects are classified under the suggestions list. Priority : Priority describes the sequence in which the Development team will look into the defects and arrange them to be rectified. Priority can be classified into 4 types Critical / P1/ High / P2 Medium/ P3 Low / P4 Usually in normal situations , the highest severity defects will be given the highest priority and the least ones accordingly, but sometimes depending on the situation and barriers between the developers and testing team's knowledge bank , the correlation may change. For example : Whenever there is a customer visit in a short notice, then all the GUI cases ( minor defects ) will receive Critical or High Priority from the developers. and Similarily If some part of the application is to be released at a later stage in another build to the testing team then the testers consider the missing functionality as Fatal, but the developers will keep it assigned at a Low priority. Below is the Defect Profile document example based on our Login Screen test case document execution . Again It is to be noted , that the template and description styles may change from company to company. Current Mood: creative (Comment on this)

4:07 am	How to Connect to a Wireless Network Using the iPod Touch The iPod touch is not only a music player, but also your gateway to the world via the Internet. In order to connect to the iTunes music store and use the email and web-browsing features of your iPod touch, you must first connect to a wireless network. 1)Touch the "Settings" icon on the home screen of the iPod touch. The iPod does not require you to press down very hard to select an icon. Using your finger, lightly tap the application you want to activate it. 3)Select the wireless network you want to connect to. You may have more than one option based on your location. If you are prompted for a password, enter it and touch "Join." 4)Opt to have your iPod alert you when there is a new network you can join. This can be useful if you are no longer in range of a network you have previously used. To receive these messages, turn on the "Ask to Join Networks" feature. 5)Tell the iPod touch to "forget" a wireless network that you no longer want to use, so it will not automatically try to connect you. Under the Wi-Fi settings, tap the ">" button next to the network you want to delete and then touch "Forget this network firewall hardware. ". 6)Expect that some wireless networks detected by your iPod touch will ask you to sign up for a fee-based service. If this is acceptable to you, open up the Safari application from the home screen. You will be taken to a website that explains the terms of service and accepts credit card payments for wireless Internet access. Don't despair if you do not have a wireless network connection in your home. Public libraries often have wireless Internet access and do not charge their patrons for using it. Local cafes, coffeehouses and bookstores may also provide hotspots to their customers, but you may have to pay a fee for the service. Fully charge the battery of your iPod touch before you go in search of a wireless network. network security Using the USB cable that came with your iPod, hook your iPod up to your computer. Make sure your computer does not go into "sleep" mode or the battery may actually drain instead of charge. Current Mood: productive (Comment on this)

4:27 pm	Your Complete Guide To Laptop Security Laptops are commonplace today as they provide the users with an easy environment to work in. The features of mobility, technology and the capability of storing large information make these machines a must have ins. Losing a laptop often doesn't matter as much as the fear of losing the data it contains. In order to secure your precious information carrier, putting a security programme in place is thus a must for the individual and the organization on the whole. Whenever there is a laptop theft, only a few of the culprits are concerned about the data it contains but more are concerned with its digital treasures like the hard drives. By selling them they seek quick profits. This article is devoted on how you can secure your laptop and will give you a brief overview on how users can prevent laptop thefts. With the increasing number of laptop thefts, people have become more concerned about their possession. To support this there is available a wide range of security products depending on your requirements. Of which the most important is the users self security. network security You should be very careful with your machine while traveling. The others security means are:. Laptop Security Cables: It is the most cheapest and effective security measure available in the market. Laptop Security Cables are light weight cables that wrap around a stationary device and lock the security slot of your laptop. If your laptop is not equipped with a built-in security slot, an optional glue-on adapter is available at no extra charges. Laptop Safes: They are the most convenient security gadget available to you while you are traveling. A must have in especially for the travelers! Your machine is transported safely in a sturdy trunk in your very own vehicle. Track IT: This product helps create a "maximum separate zone" around both the user and the laptop. As soon as you move out of the range of your machine, the alarm rings and once back within the range, it stops. It is an ideal solution for preventing thefts in crowded areas. But the interference from the environment such as the metal beams and other radio sources is a drawback to this solution which reduces the usefulness of the product. Another method is to opt for an alarm that relies on the movement of the object that is attached to it. If the object that is attached to the sensor is moved an alarm will be raised. Caveo's Anti-Theft PCMCIA Card: This device monitors the position of your laptop. There are sensors that detect the movement of laptop outside the designated workforce, several events can occur like the alarm will ring, where upon Caveo will shut down and effectively lock the machine by preventing it from booting without a proper action. Biometrics: It provides another means of blocking access by allowing only the users who authenticate their identity with various physical characteristics such as the finger prints, voice patterns or their retina scan. These security products provide effective theft deterrents and access controls but ultimately it all depends on the individual user to prevent their laptop theft. Users need to be specifically careful in the public locations business firewalls. Current Mood: satisfied (Comment on this)
