2.2) Hardware includes the mouse, keyboard and screen of your computer.
Correct Answer
A. True
Explanation
Hardware refers to the physical components of a computer system that can be seen and touched. This includes devices such as the mouse, keyboard, and screen, which are essential peripherals for inputting and outputting data. Therefore, the statement that hardware includes the mouse, keyboard, and screen of a computer is true.
8.
2.3) An ATM and a calculator are really just computers.
Correct Answer
A. True
Explanation
An ATM and a calculator can be considered as computers because they both have the ability to process information and perform calculations. Both devices have a central processing unit (CPU) that carries out instructions, input/output devices for interaction with users, and memory for storing data. While their functionalities may differ, they share fundamental characteristics of a computer system. Therefore, it is true to say that an ATM and a calculator are really just computers.
9.
2.4) To work, a program does not need to use the CPU, memory and storage of the operating system.
Correct Answer
B. False
Explanation
A program requires the CPU, memory, and storage of the operating system to function properly. These resources are essential for executing the program's instructions, storing and retrieving data, and managing system resources. Without access to these resources, the program would not be able to perform any tasks or operations. Therefore, the statement that a program does not need to use the CPU, memory, and storage of the operating system is false.
10.
2.5) ALU is the acronym for Arithmetic and Logical Unit.
Correct Answer
A. True
Explanation
ALU stands for Arithmetic and Logical Unit. This unit is a fundamental component of a computer processor that performs arithmetic operations, such as addition and subtraction, as well as logical operations, such as AND, OR, and NOT. The ALU is responsible for executing the instructions of a computer program and manipulating data within the processor. Therefore, the statement that ALU is the acronym for Arithmetic and Logical Unit is true.
11.
2.6) The computer can only run one program at a time.
Correct Answer
B. False
Explanation
The statement is false because modern computers are capable of running multiple programs simultaneously. This is achieved through multitasking, where the computer switches between different programs rapidly, giving the illusion of running them simultaneously. Multitasking allows users to open multiple applications, perform tasks in the background, and switch between programs seamlessly. Additionally, modern operating systems have features like task managers and virtual desktops that further enhance multitasking capabilities.

2.8) The monitor is called a peripheral of the computer.
Correct Answer
B. False
Explanation
The given statement is false because a monitor is not considered a peripheral of the computer. A peripheral is an external device that connects to the computer and provides additional functionality, such as a printer or a keyboard. However, a monitor is an essential component of the computer system and is directly connected to the computer to display visual output. It is not considered an external peripheral device.

2.9) A RAM is a permanent memory of a computer.
Correct Answer
B. False
Explanation
The given statement is false. A RAM (Random Access Memory) is not a permanent memory of a computer. It is a volatile memory that is used for temporary storage of data that is actively being used by the computer. The data stored in RAM is lost when the computer is powered off or restarted. Permanent memory in a computer is typically referred to as secondary storage, such as hard drives or solid-state drives, where data is stored even when the computer is turned off.
