What special function does a cache server perform? Why is this useful for larger organizations? A cache server makes frequently used pages available. Larger companies use cache server to make sure pages that they use to market their products are ready to send instead of asking for a full request from a webpage host.
A cache server is a dedicated network server or service acting as a server that saves Web pages or other Internet content locally. By placing previously requested information in temporary storage, or cache, a cache server both speeds up access to data and reduces demand on an enterprise's bandwidth.
First, caching attempts to reduce the latency of the user associated with obtaining web documents. Latency can be reduced because the cache is naturally much nearer to the client than the provider of the content. Second, caching tries to reduce the network traffic from the internet servers.
Server-side caching When caching systems are implemented between the client and the application server, they are known as proxy servers or proxy caches. Ideally, caches are placed as close to the client as possible without compromising security. DynaCache is an example of a server-side caching mechanism.

Cache memory holds frequently used instructions/data which the processor may require next and it is faster access memory than RAM, since it is on the same chip as the processor. This reduces the need for frequent slower memory retrievals from main memory, which may otherwise keep the CPU waiting.
A cache's primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer. Trading off capacity for speed, a cache typically stores a subset of data transiently, in contrast to databases whose data is usually complete and durable.
Cache memory operates between 10 to 100 times faster than RAM, requiring only a few nanoseconds to respond to a CPU request. The name of the actual hardware that is used for cache memory is high-speed static random access memory (SRAM).
Caching improves and speeds up browsing. Once you've downloaded an asset, it lives (for a time) on your machine. Retrieving files from your hard drive will always be faster than retrieving them from a remote server, no matter how fast your Internet connection.
Cache isn't only used by your Android phone—it's also a function of desktop browsers and other software. Without cache, your device would have to reload images and other elements every time you accessed them, which is inefficient.
Server caching helps limit the cost incurred by the server and its underlying systems. Many requests made by clients can either be responded to using the same data, or responded to using parts of the same requests made by others.
Cache Server is a server used to speed corporate access to Web content on the Internet by caching the Web pages that users most frequently request.
