Detailed explanation-1: -False. It is possible to run and process things directly on the Hard Disk Drive without loading them up in RAM. True.
Detailed explanation-2: -This is simply done because your RAM is way faster than your Hard Disk. When your computer executes a program, the CPU reads all the instructions from memory one after another and executes them. The CPU itself cannot store the whole program while executing it, so it has to be read from somewhere else.
Detailed explanation-3: -A computer can still function without a hard drive. This can be done through a network, USB, CD, or DVD. Believe it or not.
Detailed explanation-4: -The CPU starts and fetches instructions into RAM from the BIOS, which is stored in the ROM. The BIOS starts the monitor and keyboard, and does some basic checks to make sure the computer is working properly. For example, it will look for the RAM. The BIOS then starts the boot sequence.
Detailed explanation-5: -There is an inevitable connection between the memory and the hard drive of the computer. Any problem in one of them, affects the other directly.
