MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -SRAM is used as cache memory in a computer, which stores frequently used data for quick access by the CPU. DRAM is used as main memory, or RAM, which stores data that the CPU is currently using or processing.

Detailed explanation-2: -SRAM is commonly used for a computer’s cache memory, such as a processor’s L2 or L3 cache. It is not used for a computer’s main memory because of its cost and size. Most computers use DRAM instead because it supports greater densities at a lower cost per megabyte (MB).

Detailed explanation-3: -The SRAM component of our hierarchical memory system is called a cache. It provides low-latency access to recently-accessed blocks of data.

Detailed explanation-4: -L1 is the primary type cache memory. The Size of the L1 cache very small comparison to others that is between 2KB to 64KB, it depent on computer processor. It is a embedded register in the computer microprocessor(CPU). The Instructions that are required by the CPU that are firstly searched in L1 Cache.

Detailed explanation-5: -Memory caching is effective because most programs access the same data or instructions over and over. By keeping as much of this information as possible in SRAM, the computer avoids accessing the slower DRAM.
