Test: Main Memory Organisation - Computer Science Engineering (CSE) MCQ

Memory is the place where data can be stored and later retrieved. Memory can be of classified into register, cache, main memory, etc.

Registers are the fastest means of access for CPU. Registers are the small memory locations which are present closest to the CPU.

 The size of the main memory depends on the size of the address bus of the CPU. The main memory mainly consists of RAM and ROM, where RAM contains the current data and programs and ROM contains permanent programs like BIOS.

The tertiary storage is the correct option. It is used in the realms of enterprise storage and scientific computing on large computer systems and business computer networks and is something a typical personal computer never sees firsthand.

The MAR stands for memory address register. It holds the address of the active memory location.

Storage capacity is the product of a number of memory locations that is the number of words and the word size or the number of bits stored per location. Storage capacity should be as large as possible.

The main memory is implemented using semiconductor chips. Main memory is located on the motherboard. It mainly consists of RAM and small amount of ROM.

The secondary memory is independent of the address bus. It increases the storage space. It is implemented in the form of magnetic storage devices.

The internal registers are present on-chip. They are therefore present inside the CPU. L1 cache is also present on-chip inside the CPU.

Cache Memory is the memory closest to the CPU. Registers, Cache and the main memory are the means of onboard storage in the computer system.
