Key Components of a Computer System

1 / 7

When a user presses a key on the keyboard to type a letter, which sequence best explains how the computer components interact together to process the input and display it on the monitor?

A) Monitor → CPU → Keyboard → RAM

B) CPU → Keyboard → Monitor → RAM

C) Keyboard → CPU → RAM → Monitor

D) Keyboard → RAM → CPU → Monitor

2 / 7

A student clicks the Save button while working on a document. Which explanation correctly describes how different computer components cooperate to complete this task?

A) Monitor sends the file to storage through RAM

B) RAM permanently stores the file after processing

C) Storage directly saves data without involving the CPU

D) CPU processes the save command, RAM provides temporary access, and storage permanently stores the file

3 / 7

During the execution of a program, instructions are continuously transferred between memory and the processor. Why is this interaction necessary?

A) Because RAM performs all calculations itself

B) Because the CPU cannot process instructions stored in memory

C) Because the CPU fetches instructions from RAM before executing them

D) Because storage devices execute instructions faster than the CPU

4 / 7

A computer is playing a video. Which statement best explains the interaction among components responsible for smooth playback?

A) Storage provides the video data, RAM temporarily holds it, CPU processes it, and the monitor displays it

B) The monitor stores the video while the CPU displays it

C) RAM permanently saves the video file during playback

D) The keyboard controls all video processing activities

5 / 7

A user enters a calculation into a spreadsheet application. Which component is mainly responsible for carrying out the instructions while interacting with other hardware components?

A) CPU

B) Storage Device

C) Keyboard

D) Monitor

6 / 7

If RAM suddenly stops functioning while a program is running, which effect would most likely occur due to the disruption of component interaction?

A) The keyboard will replace the function of RAM

B) The monitor will permanently store all data

C) The CPU will continue processing normally without memory

D) The computer may freeze because the CPU cannot access required instructions and data

7 / 7

In a computer system, data often travels through communication pathways called buses. Why are buses important for interaction among components?

A) They allow data, instructions, and control signals to move between components

B) They permanently store instructions for the CPU

C) They convert input devices into output devices

D) They display processed information on the screen
