  • 2. 

    The digit 0 or 1 is called a binary digit, or _____.

    Explanation
    A binary digit, also known as a bit, is a fundamental unit of information in computing and digital communications. It can represent either a 0 or a 1, and is the building block of binary code which is used to represent and process data in computers.

    The ___________ monitors the overall activity of the computer and provides services.

    Explanation
    The operating system is responsible for monitoring the overall activity of the computer and providing various services. It acts as an intermediary between the user and the computer hardware, managing tasks such as memory allocation, file management, and process scheduling. It also provides a user interface and allows users to interact with the computer system. Overall, the operating system plays a crucial role in ensuring the efficient and effective operation of the computer.

    True or False: System Programs control the computer.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    System Programs are responsible for controlling and managing the computer's resources and operations. They provide essential services and functions that enable the computer to function properly. Examples of system programs include the operating system, device drivers, utility programs, and system libraries. These programs handle tasks such as memory management, file management, process scheduling, and input/output operations. Therefore, it is correct to say that system programs control the computer.

    True or False: Assembly languages were developed to make the programmer’s job easier.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Assembly languages were developed to make the programmer's job easier. Assembly language is a low-level programming language that uses mnemonic codes and symbols to represent machine instructions. It is easier for programmers to understand and write assembly code compared to machine code, which consists of binary instructions. Assembly languages provide a level of abstraction and readability that makes programming more manageable and efficient. Therefore, it is correct to say that assembly languages were developed to make the programmer's job easier.

  • 6. 

    A program called a(n) ______ translates instructions written in Java into bytecode.

    Correct Answer
    compiler
    Explanation
    A compiler is a program that translates instructions written in a high-level programming language like Java into a lower-level language called bytecode. This bytecode can then be executed by a virtual machine or interpreter. The compiler analyzes the code, checks for errors, and converts it into a form that can be understood and executed by the computer. In the case of Java, the compiler converts the code into bytecode, which is platform-independent and can be run on any device with a Java Virtual Machine (JVM).

    True or False: A keyboard is an example of an output device.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A keyboard is not an example of an output device, but rather an input device. It is used to input data and commands into a computer system, allowing the user to interact with the device. Output devices, on the other hand, are used to display or provide information to the user, such as monitors, printers, or speakers.

    Rate this question:

  • 8. 

    The ____ is the brain of the computer.

    Correct Answer
    Central Processing Unit (CPU)
    Explanation
    The brain of the computer is referred to as the Central Processing Unit (CPU). The CPU is responsible for executing instructions and performing calculations, making it the most important component of a computer system. It controls and coordinates the activities of all other hardware components, such as memory, input/output devices, and the operating system. The CPU processes data and instructions by fetching them from memory, decoding them, and then executing them. It is often considered the "brain" of the computer because it carries out all the essential operations required for the computer to function.

    Rate this question:

  • 9. 

    The ___________ carries out all arithmetic and logical operations.

    Correct Answer
    arithmetic logic unit (ALU)
    Explanation
    The arithmetic logic unit (ALU) is responsible for performing all arithmetic and logical operations in a computer. It is a crucial component of the central processing unit (CPU) and is responsible for executing tasks such as addition, subtraction, multiplication, division, and comparison operations. The ALU performs these operations by manipulating binary data and producing the desired result based on the given instructions. It plays a vital role in the overall functioning of a computer system by performing the necessary calculations and logical decisions required for various tasks and operations.

  • 10. 

    A program called a linker translates each bytecode instruction into the machine language of your computer, and then executes it.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is false because a linker is a program that combines multiple object files into a single executable file, and it does not translate bytecode instructions into machine language. The process of translating bytecode into machine language is typically done by a virtual machine or interpreter.
