Question 5

Purpose of CPU

Answer 5

CPU is the brain of the computer that interpreting and executing instructions from software programs, essentially performing all the calculations and data processing needed to run applications and the operating system

Question 6

Memory (RAM): Random Access Memory

Answer 6

It is a volatile memory that temporarily stores data that is currently being used or processed by the CPU.

meaning of volatile memory: the data stored in the RAM is only temporarily held and will be lost when the power is turned off such as data disappears when the computer is shut down or loses power

purpose: to store data that the CPU needs to access quickly while actively processing information such as loading apps, browsing websites, and editing documents
