Cache RAM

Cache RAM lets know about Cache RAM! The CPU must deliver its data at a very high speed. The regular RAM can not keep up with that speed. Therefore, a special RAM type called cache is used as a buffer - temporary storage.  To get top performance from the CPU, the number of outgoing transactions must be minimized. The more data transmissions, which can be contained inside the CPU, the better the performance.  Therefore,the 486 was equipped with a built in mathematical co-processor, floating point unit and 8 KB L1-cache RAM. These two features help minimize the data flow in and out of the CPU.  Cache RAM becomes especially important in clock doubled CPU's, where internal clock frequency is much higher than external.  Then the cache RAM enhances the "horsepower" of the CPU, by allowing faster receipt or delivery of data. Beginning with 486 processors, two layers of cache are employed.  The fastest cache RAM is inside the CPU. It is called L1 cache. The next l...

Computer Software

Computer Software Computer software , or simply software , is a generic term that refers to a collection of data or computer instructions that tell the computer how to work, in contrast to the physical hardware from which the system is built, that actually performs the work.  In computer science and software engineering, computer software is all information processed by computer systems, programs and data.  Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media.  Computer hardware and software require each other and neither can be realistically used on its own.
