Doesn’t require any searching, so it’s not expensive as other caches

Instead of specifying a unique location for each memory block, ….. allow a main memory block to be replaced anywhere

Associative memory requires special hardware to allow associative searching and is thus …..

Direct mapped is

direct map is ….

fully associative is ….

it requires a larger tag to be stored with the block which results in a larger cache with special hardware

is a combination of 2 approaches

is like direct mapped in that we use the address to map the block to a certain cache location

instead of mapping a single cache block, an address maps to a set of several cache blocks

in N-way set associative cache mapping, sets in cache can be in different sizes

The size of set can vary from cache to cache

The I/O subsystem of a computer provides an efficient mode of communication between the central system and the outside environment. It handles all the input-output operations of the computer system

Input or output devices that are connected to computer are

These devices are designed to read information into or out of the memory unit upon command from the CPU and are considered to be the part of computer system

peripheral devices are also called peripherals

Allows information output, from the computer to the outside world
