What is the bus on the back?
Bus on the side side is a piece of computer hardware that connects the central processing unit (CPU) with level 2 (L2) memory and sometimes at level 1 (L1). This connection is linked when the CPU needs to store memory in the cache or to load the memory from it. Connecting CPU and cache with a bus on the side side is important because the CPU will have easier time processing information that has previously been stored or processed. In most computers, this bus is as fast or almost as fast as a CPU.
During operations, the CPU may need a cache for some reason and the bus on the back serves as a bridge between them. The cache is a memory that stores things that have already been viewed. For example, if someone has recently opened a picture, a text document or a website, then the file will save the file for a short time; The memory is thrown away if the user does not return to the file in the period period. Most rear buses are associated with L2 cache while some also associate with L1.
As a bridge, a bus side bus allows you to move the cache in two different directions. If the CPU needs to temporarily save a part or the entire process to return to the process later, it will use the bus to store the process in the cache. When the CPU needs something from the cache, he instructs the bus to get it.
While the cache usually has the smallest amount of memory on the computer, it is very fast as a result. For this reason, the CPU can use a bus on the side side to speed up otherwise lengthy processes, but only if they have been done recently. For example, if someone performs a long mathematical problem or draws a complicated image, the CPU can complete a few minutes or more. If the user again performs the same function, the CPU will be able to repeat this process much faster by obtaining information from the cache.
cache is very fast and Because CPU needs tUTO memory quickly, the bus on the back is usually made to have a high speed of workmanship. Most computers set this bus near the same speed as the CPU, with the lowest setting is usually about half the CPU speed. If the bus is set to a lower speed, it can be faster to repeat the recent process and remove the need on the back of the bus.
