See lessWhich of the following is true about pseudocode
Pseudo code is an informal way of programming description that does not require any strict programming language syntax or underlying technology considerations. It is used for creating an outline or a rough draft of a program. Pseudo code summarizes a program's flow, but excludes underlying details.

It manages the computer's memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's language. Without an operating system, a computer is useless.

See lessBlock caches or buffer caches are used
Block caches or buffer caches are used to improve disk performance to handle interrupts to increase the capacity of the main memory to speed up the main memory. Reading from a disk is very slow compared to accessing (real) memory.
