A central processing unit (CPU) consists of two main parts. These are …………
- A.
Arithmetic-Logic Unit and Control Unit
- B.
Arithmetic-Control Unit and Logic Unit
- C.
Control Unit and Arithmetic Unit
- D.
Control Unit and Logic Unit
Correct Answer
A. Arithmetic-Logic Unit and Control UnitExplanation
The central processing unit (CPU) is made up of two main parts: the Arithmetic-Logic Unit (ALU) and the Control Unit. The ALU is responsible for performing arithmetic and logical operations, such as addition, subtraction, and comparison. The Control Unit, on the other hand, manages the execution of instructions and coordinates the activities of the other components in the CPU. Together, the ALU and Control Unit work together to carry out the processing and control functions of the CPU.Rate this question:

A device driver is ........
- A.
A computer program that allows the operating system to communicate with the device.
- B.
The person who delivers hardware devices to a computer store
- C.
The connector that allows you to attach the device to a computer
- D.
The power supply for the device connected to the computer
Correct Answer
A. A computer program that allows the operating system to communicate with the device.Explanation
A device driver is a computer program that allows the operating system to communicate with the device. It acts as a translator between the operating system and the hardware device, enabling them to exchange information and instructions. Without a device driver, the operating system would not be able to understand how to interact with the device, and the device would not function properly. Thus, the device driver plays a crucial role in facilitating communication and ensuring the proper functioning of hardware devices connected to a computer.Rate this question:

____________ refers to millions and ____________ refers to billions.
- A.
Mega, Giga
- B.
Giga, Mega
- C.
Miga, Giga
- D.
Mega, Tera
Correct Answer
A. Mega, GigaExplanation
The term "Mega" refers to millions, while the term "Giga" refers to billions. These terms are commonly used in the field of data storage and computer memory to indicate the size or capacity of storage devices. "Mega" is a prefix that denotes a factor of one million, while "Giga" denotes a factor of one billion. Therefore, when discussing large quantities or measurements, "Mega" would be used to represent millions and "Giga" would be used to represent billions.Rate this question:

The part of the computer that does the calculation, moving and processing of information is called …………
- A.
CPU
- B.
RAM
- C.
Motherboard
- D.
ROM
Correct Answer
A. CPUExplanation
The CPU, or Central Processing Unit, is responsible for performing calculations, moving data, and processing information in a computer. It is often referred to as the "brain" of the computer, as it carries out the instructions of a computer program by performing basic arithmetic, logical, control, and input/output (I/O) operations. The CPU interacts with other components of the computer, such as RAM and the motherboard, to execute tasks and run programs efficiently.Rate this question:

The name for the short-term memory of the computer that is lost when the computer is turned off is ……..
- A.
RAM
- B.
CPU
- C.
ROM
- D.
TCP
Correct Answer
A. RAMExplanation
RAM stands for Random Access Memory. It is a type of computer memory that is used to store data that is actively being used by the computer. It is considered as the short-term memory of the computer because it can be quickly read from and written to by the computer's processor. However, the data stored in RAM is volatile, meaning it is lost when the computer is turned off or restarted. This is why RAM is often referred to as temporary or volatile memory.Rate this question:

What is a computer network?
- A.
Two or more computers connected that can share data and programs.
- B.
A group of computers that share the same power supply.
- C.
A computer that can be used by different users simultaneously.
- D.
Any sets of computers manufactured by the same company.
Correct Answer
A. Two or more computers connected that can share data and programs.Explanation
A computer network refers to a system where two or more computers are connected to each other, allowing them to share data and programs. This enables users to easily communicate, collaborate, and access shared resources. It facilitates the exchange of information and promotes efficiency and productivity among connected devices.Rate this question:

What is the main end output device when using Word Processing or Desktop Publishing software?
- A.
Monitor
- B.
Printer
- C.
Projector
- D.
Keyboard
Correct Answer
A. MonitorExplanation
The main end output device when using Word Processing or Desktop Publishing software is the monitor.

An example of an output device is ……….
- A.
The monitor
- B.
The keyboard
- C.
The power cord
- D.
The mouse
Correct Answer
A. The monitorExplanation
An example of an output device is the monitor. A monitor is a display screen that visually presents information to the user. It allows the user to view output from the computer, such as text, images, videos, and graphics. The monitor receives signals from the computer and converts them into visual representations that can be seen by the user. It is an essential component of a computer system as it provides visual feedback and allows users to interact with the computer.Rate this question:

Devices which are used to receive data from central processing unit are classified as ….
- A.
Input devices
- B.
Output devices
- C.
Input/output devices
- D.
Signal devices
Correct Answer
B. Output devicesExplanation
Output devices are used to receive data from the central processing unit and display or present it to the user. These devices include monitors, printers, speakers, and projectors. They allow the user to view or hear the processed information generated by the CPU. Input devices, on the other hand, are used to send data to the CPU for processing, such as keyboards, mice, and scanners. Input/output devices can perform both input and output functions, while signal devices are not typically used for receiving data from the CPU.Rate this question:

What is a NIC?
- A.
Network Interface Card
- B.
Network Interphase Card
- C.
Network International Card
- D.
Network Interior Card
Correct Answer
A. Network Interface CardExplanation
A NIC, or Network Interface Card, is a hardware component that allows a computer to connect to a network. It provides the physical interface between the computer and the network, enabling the transmission and reception of data packets. The NIC is responsible for converting the data from the computer into a format that can be transmitted over the network, and vice versa. It is an essential component for network communication and is commonly found in desktop computers, laptops, and servers.Rate this question:
