Quiz On Computer Repair And Maintenance

1. It performs most of the calculations which enable a computer to function, and is sometimes referred to as the "brain" of the computer.

Input and output device

Buses

CPU

Mouse

The CPU, or Central Processing Unit, is responsible for performing most of the calculations that enable a computer to function. It is often referred to as the "brain" of the computer because it processes and executes instructions, performs arithmetic and logical operations, and manages data movement between different parts of the computer system. Without the CPU, a computer would not be able to carry out its tasks and operations effectively.

2. Converts alternating current (AC) electric power to low-voltage DC power for the internal components of the computer

Power supply

Case

Expansion cards

Storage devices

The power supply is responsible for converting the alternating current (AC) electric power from the wall outlet into low-voltage direct current (DC) power that is required by the internal components of the computer. It provides a steady and regulated power supply to ensure the proper functioning of the computer. Without a power supply, the computer would not receive the correct voltage and current needed to operate, resulting in it not turning on or experiencing power-related issues.

3. Stores the code and data that are being actively accessed by the CPU.

CPU

RAM

Mouse

Monitor

RAM stands for Random Access Memory. It is a type of computer memory that stores the code and data that are currently being actively accessed by the CPU. Unlike other types of memory, RAM allows for fast and random access to any location, which makes it ideal for storing temporary data and instructions that the CPU needs to access quickly. Therefore, RAM is the correct answer as it directly relates to the given explanation.

4. Refers to computer components and recording media that retain digital data.

Storage devices

Fixed media

Removable media

Software

The correct answer is "Storage devices" because it refers to computer components and recording media that retain digital data. Storage devices are hardware devices used to store and retrieve data, such as hard drives, solid-state drives, USB flash drives, and memory cards. These devices provide a means to store and access digital information, allowing users to save and retrieve files, programs, and other data.

5. Mediates communication between the CPU and the other components of the system, including main memory.

CPU

RAM

ROM

Chipset

The chipset is responsible for mediating communication between the CPU and the other components of the system, including main memory. It acts as a bridge, allowing data and instructions to be transferred between the CPU and RAM, ROM, and other peripherals. The chipset also controls the flow of data and manages the system's resources, ensuring smooth operation and coordination between different hardware components.
