    The memory (RAM) of a personal computer is part of the system's

    • A.

      Operating system

    • B.

      Hardware

    • C.

      Software 

    Correct Answer
    B. Hardware
    Explanation
    The memory (RAM) of a personal computer is considered hardware because it is a physical component of the computer system. Hardware refers to the tangible parts of a computer system that can be touched and interacted with, such as the motherboard, processor, and memory. In contrast, software refers to the programs and instructions that run on the hardware. Therefore, the memory (RAM) being a physical component of the computer system makes it a part of the hardware.

    The ASCII character set uses how many bits to represent each character?

    • A.

      8

    • B.

      256

    • C.

      16

    Correct Answer
    A. 8
    Explanation
    The ASCII character set uses 8 bits to represent each character. ASCII stands for American Standard Code for Information Interchange, and it is a character encoding standard that assigns unique numeric codes to represent characters. With 8 bits, a total of 256 unique characters can be represented, including letters, numbers, symbols, and control characters. Therefore, the correct answer is 8.

    When your Hard Disk is infected with a virus, then the first thing you should do:

    • A.

      Copy all your files to a floppy diskette

    • B.

      Clean the virus from a clean floppy diskette

    • C.

      Shut down the computer and turn it on again

    • D.

      Copy the infected files to a diskette and continue working

    Correct Answer
    A. Copy all your files to a floppy diskette
    Explanation
    When your Hard Disk is infected with a virus, the first thing you should do is to copy all your files to a floppy diskette. This is because the virus can potentially damage or corrupt your files, and by copying them to a separate diskette, you ensure that they are safely backed up and protected from further harm. This allows you to recover your important files even if the virus causes damage to your hard disk.

    The CPU consists of:

    • A.

      ALU, CU, and RAM.

    • B.

      ROM, ALU, and RAM.

    • C.

      CU, PU, and ALU.

    • D.

      ALU, Registers, and CU.

    Correct Answer
    D. ALU, Registers, and CU.
    Explanation
    The CPU (Central Processing Unit) is the main component of a computer that performs most of the processing inside the computer. It consists of three main components: ALU (Arithmetic Logic Unit), Registers, and CU (Control Unit). The ALU is responsible for performing arithmetic and logical operations, the Registers are small storage units used to store data temporarily, and the CU controls the flow of data and instructions within the CPU. Therefore, the correct answer is ALU, Registers, and CU.

      Used to store user programs and data while running.

    • D.

      B+c.

    Correct Answer
    D. B+c.
    Explanation
    The main memory is composed of RAM, ROM, and Hard Disk. It can be either temporary or permanent. It is used to store user programs and data while they are running. The correct answer, b+c, indicates that the main memory consists of both RAM and ROM, as mentioned in the given information.

    Correct Answer
    A. Copy all your files to a floppy diskette
    Explanation
    When your Hard Disk is infected with a virus, the first thing you should do is to copy all your files to a floppy diskette. This is because the virus may corrupt or delete your files, so it is important to have a backup of your important data. By copying the files to a floppy diskette, you can ensure that your data is safe and can be accessed later.

    The Magnetic Disk:

    • A.

      Classified as a secondary storage.

    • B.

      It is cheap and volatile.

    • C.

      It is an output unit.

    • D.

      A+b.

    Correct Answer
    A. Classified as a secondary storage.
    Explanation
    The given statement correctly identifies the magnetic disk as a secondary storage device. Secondary storage refers to non-volatile storage that can retain data even when the power is turned off. The magnetic disk fits this description as it uses magnetic materials to store data and is commonly used for long-term storage in computers. It is also mentioned that the magnetic disk is cheap, which is another characteristic of this type of storage. However, the statement incorrectly states that the magnetic disk is volatile, which is not true as secondary storage devices are non-volatile. The statement also does not provide any information about the magnetic disk being an output unit or the equation a+b, making them irrelevant to the correct answer.

    Rate this question:

  • 10. 

    Which of the following statement is correct:

    • A.

      Mini-computers more powerful than mainframes

    • B.

      Micro-computers such as laptops.

    • C.

      Mini-computers are suitable for personals.

    • D.

      Mainframes are suitable for small companies.

    Correct Answer
    B. Micro-computers such as laptops.
    Explanation
    The correct answer is "Micro-computers such as laptops." This statement is correct because micro-computers, which include laptops, are generally smaller and less powerful than mini-computers and mainframes. Mini-computers are typically more powerful than mainframes, and mainframes are designed for large-scale operations and are suitable for large companies, not small ones.

    The computer viruses has the ability to:

    • A.

      Link it self to other programs.

    • B.

      Compress itself.

    • C.

      Coordinates the activities of the computer.

    • D.

      Make backups of your files.

    Correct Answer
    A. Link it self to other programs.
    Explanation
    Computer viruses have the ability to link themselves to other programs, allowing them to spread and infect multiple files or systems. By attaching their code to other programs, viruses can easily transfer from one computer to another, often without the user's knowledge or consent. This ability to self-replicate and spread is a key characteristic of computer viruses and is a major concern for computer security.

    Rate this question:

  • 12. 

    Which of the following is not correct:

    • A.

      A computer virus is a system program designed to destroy other programs.

    • B.

      If the floppy disk is write-protect, the virus cannot infect the files.

    • C.

      If the computer speed decreased, a virus could infect the computer.

    • D.

      F-prot is one of the unti-virus programs.

    Correct Answer
    D. F-prot is one of the unti-virus programs.
    Explanation
    The given statement "F-prot is one of the unti-virus programs" is not correct. F-prot is actually an antivirus program, not an "unti-virus" program. An antivirus program is designed to detect, prevent, and remove computer viruses, while "unti-virus" is not a recognized term in the context of computer security.

    • E.

      None of the above.

    Correct Answer
    A. Copy all your files to a floppy diskette
    Explanation
    When a hard disk is infected with a virus, it is important to first copy all the files to a floppy diskette. This is because the virus may damage or corrupt the files on the hard disk, making it difficult to recover them later. By copying the files to a floppy diskette, you can ensure that your important data is safely stored and can be accessed even if the hard disk is further affected by the virus.

    • D.

      Used to store user programs and data.

    Correct Answer
    D. Used to store user programs and data.
    Explanation
    The given answer, "Used to store user programs and data," is correct because one of the main functions of an operating system is to provide a platform for users to run their programs and store their data. The operating system manages the storage and organization of user programs and data, ensuring they are accessible and protected. This function is essential for users to effectively utilize their computer systems.

    Correct Answer
    A. Displays drives, and printers on your system available to the network.
    Explanation
    The Network Neighborhood displays the drives and printers on your system that are available to the network. This means that other devices connected to the same network can access and use these resources. It does not guide you through a step-by-step process of connecting to the network, nor does it contain the names of the network neighborhood. Its main function is to show the shared drives and printers that can be accessed by other network users.
