Cache: What is it?

In a computing setting, a cache is a piece of hardware or program that is used to temporarily store something, typically data. To improve the speed of recently or often accessed data, a small quantity of quicker, more expensive memory is employed. Data that has been cached is transiently kept on a local storage medium that is available to the cache clients and unrelated to the main storage.

b) Address: 164250 → Page number: 161, Offset: 202

c) Address: 121357 → Page number: 119, Offset: 333

d) Address: 16479315 → Page number: 16093, Offset: 659

e) Address: 27253187 → Page number: 26708, Offset: 963.

Note that an offset is a numerical value that represents the distance of a particular location within a file, block of memory, or other data structure from a reference point. It is often used to specify the location of a particular piece of data within a larger structure.

An address reference is a value that represents the location of a specific piece of data within a computer's memory.

To determine the page numbers and offsets for the given address references, you will need to divide the address by the page size. The page number will be the result of the division, and the offset will be the remainder.

Thus, for a:
Address: 21205 → Page number: 21205 / 1024 = 20,

Offset: 21205 % 1024 = 905

for b,
Address: 164250 → Page number: 164250 / 1024 = 161, Offset: 164250 % 1024 = 202

for c,
Address: 121357 → Page number: 121357 / 1024 = 119,

Offset: 121357 % 1024 = 333

for d,

Address: 16479315 => Page number: 16479315 / 1024 = 16093,

Offset: 16479315 % 1024 = 659

for e,

Address: 27253187 => Page number: 27253187 / 1024 = 26708,

Offset: 27253187 % 1024 = 963

In conclusion,

a) Address: 21205 → Page number: 20, Offset: 905

b) Address: 164250 → Page number: 161, Offset: 202

c) Address: 121357 → Page number: 119, Offset: 333

d) Address: 16479315 → Page number: 16093, Offset: 659
