Structs are value-type variables and are thus saved on the stack, additional overhead but faster retrieval.  Another difference is that structs cannot inherit.

In a cached system, the base addresses of the last few referenced pages is maintained in registers called the TLB that aids in faster lookup. TLB contains those page-table entries that have been most recently used. Normally, each virtual memory reference causes 2 physical memory accesses-- one to fetch appropriate page-table entry, and one to fetch the desired data. Using TLB in-between, this is reduced to just one physical memory access in cases of TLB-hit.

During the fork() system call the Kernel makes a copy of the parent process's address space and attaches it to the child process.

But the vfork() system call do not makes any copy of the parent's address space, so it is faster than the fork() system call. The child process as a result of the vfork() system call executes exec() system call. The child process from vfork() system call executes in the parent's address space (this can overwrite the parent's data and stack ) which suspends the parent process until the child process exits.  

Enhanced Data GSM Environment (EDGE) is a new, faster version of GSM. EDGE is designed to support transfer rates up to 384Kbps and enable the delivery of video and other high-bandwidth applications. EDGE is the result of a joint effort between TDMA operators, vendors and carriers and the GSM Alliance.

Third generation (3G) wireless networks will offer faster data transfer rates than current networks. The first generation of wireless (1G) was analog cellular. The second generation (2G) is digital cellular, featuring integrated voice and data communications. So-called 2.5G networks offer incremental speed increases. 3G networks will offer dramatically improved data transfer rates, enabling new wireless applications such as streaming media.

All of those are open source resource. Security of  Linux is very more than windows. Apache is a better server that IIS both in functionality and security. Mysql is world most popular open source database. Php is more faster that asp or any other scripting language.

Feature on Cisco routers that provides faster packet processing by allowing the ciscoBus to switch packets independently without interrupting the system processor.

Microsoft introduced an alternative to CGI, the Internet Server Application Programming Interface (or ISAPI). ISAPI addresses one of the most limiting features of CGI applications. Each time a client requests the execution of a CGI application, the web server executes a separate instance of the application, sends in the user's requesting information, and serves the results of the CGI application's processing to the client. The problem with this approach is that a separate CGI application is loaded for each request. This can be quite a drain on the server's resources if there are many requests for the CGI application.ISAPI alleviates this problem by relying on dynamic link libraries (DLLs). Each ISAPI application is in the form of a single DLL that is loaded into the same memory space as the web server upon the first request for the application. Once in memory, the DLL stays in memory, answering user requests until it is explicitly released from memory. This increased efficiency in memory usage comes at a cost. All ISAPI DLLs must be thread-safe so that multiple threads can be instantiated into the DLL without causing problems with the application's function. ISAPI applications are normally faster than their equivalent CGI applications because the web server does not have to instantiate a new application every time a request is made. Once the ISAPI application DLL is loaded into memory, it stays in memory. The web server does not need to load it again
