Why memory is divided?

It is used to store data and instructions. The memory is divided into large number of small parts called cells. Each location or cell has a unique address, which varies from zero to memory size minus one. For example, if the computer has 64k words, then this memory unit has 64 * 1024 = 65536 memory locations.

What is computer memory explain its types?

Computer memory is of two basic types – Primary memory(RAM and ROM) and Secondary memory (hard drive, CD, etc). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory.

Why is it slower to read 2 bytes than 4 bytes?

The CPU will read each word of memory that your requested address straddles. This causes an amplification of up to 2X the number of memory transactions required to access the requested data. Because of this, it can very easily be slower to read two bytes than four.

What happens if a computer has no memory at all?

No memory at all means that the computer is not doing anything. For the computer to do something, it needs a program, and that program is stored in memory. No RAM (readable and writable “random access” memory)… now that’s another matter. The computer could still run a program that is stored in read-only memory (ROM), even if it has no RAM.

Why does swapping to an SSD/NVMe drive use up so much disk space?

Swapping to an SSD/NVME uses up the disk’s write cycles – every block of these disks can only take a limited number of writes before failing.
