There are 3 main uses for the static.
1. If you declare within a function:
It retains the value between function calls

2.If it is declared for a function name:
By default function is extern..so it will be visible from other files. if the function declaration is as static, it is invisible for the outer files

3.Static for global variables:
By default we can use the global variables from outside files If it is static global..that variable is limitied to with in the file

Client Side scripting: HTML is a language that provides formatting of static textual data. However it provides no true interactivity other than allowing the user to navigate from one page to another. Client side scripting enables embedding of limited programming instructions within a web page and this is performed at the client end. JavaScript and VBScript are two languages that allow you to embed client side scripting code into your static HTML files. The syntax of JavaScript is similar to Java as VBScript is similar to VB. The script is included in the tags. Server Side scripting: When the browser makes a request for a file ending with the .ASP file extension, IIS knows to bring ASP.DLL into play to interpret the ASP code in the file. Once interpreted, the results of this code are placed into the document, which is a simple HTML document before it is sent to the user.Global.asax is a file used to declare application-level events and objects. Global.asax is the ASP.NET extension of the ASP Global.asa file. Code to handle application events (such as the start and end of an application) reside in Global.asax. Such event code cannot reside in the ASP.NET page or web service code itself, since during the start or end of the application, its code has not yet been loaded (or unloaded).Global.asax is also used to declare data that is available across different application requests or across different browser sessions. This process is known as application and session state management. The Global.asax file must reside in the IIS virtual root.Events and state specified in the global file are then applied to ASP.NET all resources housed within the web application. If, for example, Global.asax defines a state application variable, all .aspx files within the virtual root will be able to access the variable. Like an ASP.NET page, the Global.asax file is compiled upon the arrival of the first request for any resource in the application. The similarity continues when changes are made to the Global.asax file; ASP.NET automatically notices the changes, recompiles the file, and directs all new requests to the newest compilation. A Global.asax file is automatically created when you create a new web application project in the VS.NET IDE.Global.asax is a file used to declare application-level events and objects.

The size of the Windows 9x swap file (WIN386.SWP) is variable and is dynamically assigned.

Virtual memory is disk drive space that is manipulated to seem like RAM. Software creates virtual memory by swapping files between RAM and the disk drive. This memory management technique effectively creates more total memory for the system's applications to use. When the system runs out of available RAM, it shifts data to the virtual memory swap file on the disk drive. However, because there is a major transfer of information that involves the hard disk drive, an overall reduction in speed is encountered with virtual memory operations.

SIMM modules were traditionally available in 30-pin and 72-pin versions; DIMMs use larger 168-pin boards.

The most popular form of error detection in PC compatibles is parity checking. In this methodology, an extra bit is added to each word in RAM and checked each time it is used. Parity checking is a simple self test used to detect RAM read-back errors. Like refreshing, parity checking requires additional circuitry and memory overhead to operate.
