    Correct Answer
    A. Motherboard
    Explanation
    The motherboard is the main circuit board of the system unit. It is responsible for connecting and providing power to all the other components of the computer, including the processor, memory, and various expansion cards. It also houses important components such as the BIOS (Basic Input/Output System) and the chipset. Without a motherboard, the computer would not be able to function properly as it serves as the central hub for all the hardware components to communicate and work together.

    Rate this question:

  • 3. 

    It interprets and carries out the basic instructions that operate a computer. It is often referred as the "brain of the computer". 

    Correct Answer
    Processor
    CPU
    Explanation
    The processor, also known as the CPU (Central Processing Unit), is responsible for interpreting and executing the fundamental instructions that control a computer's operations. It is often likened to the "brain" of the computer because it handles tasks such as arithmetic calculations, logical operations, and data processing. The processor's role is crucial in ensuring that the computer functions properly by carrying out the necessary computations and coordinating the activities of other hardware components.

    Rate this question:

  • 4. 

    It is the component of the processor that directs and coordinates most of the operations in the computer 

    • A.

      Memory

    • B.

      Bus

    • C.

      ALU

    • D.

      Control Unit

    Correct Answer
    D. Control Unit
    Explanation
    The control unit is responsible for directing and coordinating most of the operations in the computer. It manages the flow of data and instructions between the different components of the processor, such as the memory, ALU, and input/output devices. The control unit ensures that instructions are executed in the correct sequence and that data is processed accurately. It also interprets and decodes instructions, controls the timing of operations, and manages the overall operation of the processor. Without the control unit, the computer would not be able to execute instructions or perform any meaningful tasks.

    Rate this question:

  • 5. 

    A processor component that performs arithmetic, comparison and other operations.

    • A.

      Memory

    • B.

      Bus

    • C.

      ALU

    • D.

      Control Unit

    Correct Answer
    C. ALU
    Explanation
    The Arithmetic Logic Unit (ALU) is a processor component that is responsible for performing arithmetic operations such as addition, subtraction, multiplication, and division. It also performs logical operations such as comparisons, bitwise operations, and logical shifts. The ALU is an essential part of the CPU, as it carries out the actual computations and manipulations of data. Memory stores data, the bus transfers data between components, and the control unit manages and coordinates the activities of the CPU, but the ALU is the component that performs the actual mathematical and logical operations.

    Rate this question:

  • 6. 

    The binary system uses which two unique digits?

    • A.

      1 & 2

    • B.

      2 % 4

    • C.

      1 & 0

    • D.

      0 & 2

    Correct Answer(s)
    C. 1 & 0
    D. 0 & 2
    Explanation
    The binary system uses only two unique digits, which are 0 and 1. In this system, numbers are represented using only these two digits, with 0 representing a value of zero and 1 representing a value of one. This is because the binary system is based on the concept of bits, where each bit can be either 0 or 1. By combining these two digits in different ways, binary numbers can represent any value in a computer's memory or in digital communication.

    Rate this question:

  • 7. 

    Eight bits grouped together as a unit are called a ______?

    Correct Answer(s)
    byte
    Explanation
    In computer systems, a byte is a unit of digital information that consists of eight bits. It is the basic building block of data storage and processing. A byte can represent a single character or a small amount of numerical data. It is commonly used to measure file sizes, memory capacity, and data transfer rates. Therefore, when eight bits are grouped together as a unit, it is called a byte.

    Rate this question:

  • 8. 

    It consists of electronic components that store instructions waiting to be executed by the processor, data needed by those instructions, and the results of processing the data.

    • A.

      Memory

    • B.

      Processor

    • C.

      Motherboard

    • D.

      Bays

    Correct Answer
    A. Memory
    Explanation
    Memory refers to the electronic components that store instructions, data, and processed results. It is an essential component of a computer system as it holds the information needed for the processor to execute instructions. The memory stores both the instructions waiting to be executed and the data required by those instructions. It is responsible for temporarily holding and retrieving data, allowing the processor to access and manipulate it efficiently. Without memory, a computer would not be able to perform tasks or store any information.

    Rate this question:

  • 9. 

    A 500 Gigabyte (GB) hard disk has larger capacity than 700 Megabyte optical disk.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A 500 Gigabyte (GB) hard disk has a larger capacity than a 700 Megabyte optical disk because 500 GB is greater than 700 MB. The term "Gigabyte" refers to a larger unit of storage capacity compared to "Megabyte." Therefore, the statement is true.
