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.Know More
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
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 >
In computing, ROM stands for "read-only memory" and refers to a type of memory used to store data or information in a permanent form. It is applied mainly in the distribution of firmware and semiconductor integrated circuits.Full Answer >
The main differences in L1 cache, L2 cache and L3 cache are size and speed. L1 cache is the smallest and fastest, while L3 cache is the biggest and slowest. L2 cache sits between them.Full Answer >
Random access memory, or RAM, is memory storage on a computer that holds data while the computer is running so that it can be accessed quickly by the processor. RAM holds the operating system, application programs and data that is currently being used.Full Answer >
