Question about Microsoft Windows Server Standard 2003 for PC
Cache memory is an processor inbult memory, which keeps the frequently used data in it, So that the processor pickups the data from Cache memory and no need to searchthe RAM and harddisk. So the processor perfomance will get increased.

A cache is a temporary storage area where frequently accessed data can be stored for rapid access. Once the data is stored in the cache, future use can be made by accessing the cached copy rather than re-fetching or recomputing the original data, so that the average access time is shorter. Cache, therefore, helps expedite data access that the CPU would otherwise need to fetch from main memory.
A cache is a block of memory for temporary storage of data likely to be used again. The CPU and hard drive frequently use a cache, as do web browsers and web servers.
A cache is made up of a pool of entries. Each entry has a datum (a nugget of data) which is a copy of the datum in some backing store. Each entry also has a tag, which specifies the identity of the datum in the backing store of which the entry is a copy.
When the cache client (a CPU, web browser, operating system) wishes to access a datum presumably in the backing store, it first checks the cache. If an entry can be found with a tag matching that of the desired datum, the datum in the entry is used instead. This situation is known as a cache hit. So, for example, a web browser program might check its local cache on disk to see if it has a local copy of the contents of a web page at a particular URL. In this example, the URL is the tag, and the contents of the web page is the datum. The percentage of accesses that result in cache hits is known as the hit rate or hit ratio of the cache.
The advantage of cache memory is that the CPU does not have to use the motherboard’s system bus for data transfer. Whenever data must be passed through the system bus, the data transfer speed slows to the motherboard’s capability. The CPU can process data much faster by avoiding the bottleneck created by the system bus

There are many things that
might cause your PC to run slowly. It could be a fragmented disk; fragmented
registry; a virus, trojan, or spyware; high CPU and/or utilization due to too
many programs running; high disk I/O; or something else. If you feel that my answers has helped you in any way then

To check your CPU and memory utilization, run Task Manager. You can start Task Manager by pressing CTRL+ALT+DEL and then clicking on the Task Manager button. In Task manager, click on the Performance tab and check CPU Usage and PF Usage. PF Usage is an indicator of memory usage. If one or both of these is high, click on the Processes tab, and sort the columns by CPU or Memory to see what processes are consuming the resource. If you are not sure what the process "Image name" is for, google the name and you should find what the process is for.
If your CPU and memory usage are reasonable, then you may have a different issue. Even if you running anti-virus software, it may be beneficial to scan your PC with another scanner to check for viruses. No anti-virus software is 100% perfect at catching everything. Here are a few good free online virus scanners that you can run to check your PC:
