The type of memory that is primarily used as cache memory is static random access memory, or SRAM. A cache memory is also called a RAM cache or a cache store.Continue Reading
In computers, a cache is a high-speed access area that can either be a storage device or a reserved portion of main memory. The two commonly used types of caching are memory caching and disk caching. Most modern computers are equipped with an L3 or L2 cache, while older ones come with an L1 cache. Some memory caches are incorporated into the architecture of microprocessors. An L2 cache, which is an external cache, sits between the central processing unit, or CPU, and the dynamic RAM, or DRAM.
A cache memory is a section of main memory that uses the high-speed SRAM instead of the slower and cheaper DRAM. Memory caching significantly reduces the amount of time in accessing programs or instructions by storing all these information in the SRAM. Once a user accesses an already stored information, data retrieval is faster because the computer does not need to access the slower DRAM.
There are some downsides in using cache memory. Among these include that cache memory has a limited capacity and it is very costly.Learn more about Computers & Hardware
RAM, or random access memory, is measured in both size, which is typically in gigabytes, and speed, which is typically in megahertz. Computers take different sizes and types of RAM.Full Answer >
Random access memory is used to store temporary but necessary information on a computer for quick access by open programs or applications. The data stored in RAM can be accessed randomly, meaning a computer does not need to search through large blocks of data to find what it needs. This targeted access makes it possible to run complex programs quickly and efficiently.Full Answer >
The major difference between AGP and PCI is that PCI, or peripheral component interconnect cards, only have access to the inbuilt memory on the card while AGP, or accelerated graphics port cards, have access to the system memory in order to assist with complex operations like texture mapping. An AGP slot gives a video card direct access to the processor via a dedicated bus, providing it with more bandwidth than the PCI.Full Answer >
The central processing unit, the random access memory and the graphics card are the basic hardware components of a computer. In some cases, the graphics card may be a built-in part of the central processing unit. All three components communicate with each other through a motherboard.Full Answer >
