      By formatting the system

    • C.

      By removing Bios Battery

    • D.

      BY formatting only OS

    Correct Answer
    A. By changing the jumper setting in the motherboard
    Explanation
    The correct answer is by changing the jumper setting in the motherboard. This is a common method used to clear the CMOS password. By changing the jumper setting, the motherboard's configuration is reset, including the password. This allows the user to regain access to the system without the need for formatting or removing the BIOS battery.

    How many logical drives is it possible to fit onto a physical disk?

    • A.

      Maximum of 4 logical drives

    • B.

      Maximum of 8 logical drives

    • C.

      Maximum of 16 logical drives

    • D.

      Maximum of 24 logical drives

    Correct Answer
    D. Maximum of 24 logical drives
    Explanation
    The correct answer is "Maximum of 24 logical drives" because a physical disk can be partitioned into multiple logical drives. Each logical drive takes up a certain amount of space on the disk, and the total number of logical drives that can be created depends on the size of the disk and the size of each logical drive. In this case, it is possible to fit a maximum of 24 logical drives onto the physical disk.

    Wildcards in Windows?

    • A.

      ^,*,<

    • B.

      @,!,É

      É,¢,$

    • D.

      *,$,?

    Correct Answer
    D. *,$,?
    Explanation
    The answer "*,$,?" is correct because these are the wildcard characters commonly used in Windows. The asterisk (*) represents any combination of characters, the dollar sign ($) represents the end of a line, and the question mark (?) represents any single character. These wildcards are used in various contexts, such as searching for files with specific patterns or replacing text in a document.

    A Compiler is ____.

    • A.

      A combination of computer hardware

    • B.

      A program which translates from one high-level language to another

    • C.

      A program which translates from one high-level to a machine level

    • D.

      None of these

    Correct Answer
    C. A program which translates from one high-level to a machine level
    Explanation
    A compiler is a program that translates code written in a high-level programming language into machine-level code that can be understood and executed by a computer. It takes the source code as input and produces an executable file or object code as output. The compiler performs various tasks such as lexical analysis, syntax analysis, semantic analysis, optimization, and code generation. Its main purpose is to convert human-readable code into machine-readable instructions.

    When a key is pressed on the keyboard, which standard is used for converting the keystroke into the corresponding bits?

    • A.

      ANSI

    • B.

      ASCII

    • C.

      EBCDIC

    • D.

      ISO

    Correct Answer
    A. ANSI
    Explanation
    ANSI (American National Standards Institute) is the standard used for converting keystrokes into corresponding bits when a key is pressed on the keyboard. ANSI is widely used in the United States and is compatible with ASCII (American Standard Code for Information Interchange), which is a character encoding standard used for representing text in computers and other devices. EBCDIC (Extended Binary Coded Decimal Interchange Code) is another character encoding standard, but it is primarily used on IBM mainframe computers. ISO (International Organization for Standardization) is a standard-setting body that develops and publishes international standards, but it is not specifically used for converting keystrokes into bits.

    Which of the following devices have a limitation, that we can only add information to it but cannot erase or modify it:

    • A.

      Floppy Disk

    • B.

      Hard Disk

    • C.

      Tape Drive

    • D.

      CDROM

    Correct Answer
    D. CDROM
    Explanation
    CD ROM stands for Compact Disc Read-Only Memory. As the name suggests, it is a storage device that can only read information from it, but cannot erase or modify the data that is stored on it. This is because the data on a CD ROM is written during the manufacturing process and is not intended to be changed. Therefore, once data is written onto a CD ROM, it becomes permanent and cannot be altered or deleted.

    Which of the following storage devices can store maximum amount of data?

    • A.

      Floppy Disk

    • B.

      Hard Disk

    • C.

      Compact Disk

    • D.

      Magneto Optic Disk

    Correct Answer
    B. Hard Disk
    Explanation
    A hard disk can store the maximum amount of data compared to other storage devices listed. Floppy disks have very limited storage capacity, compact disks can store more data than floppy disks but less than hard disks, and magneto optic disks have a higher storage capacity than compact disks but still less than hard disks. Therefore, the hard disk is the correct answer as it can store the maximum amount of data.

    Memory is made up of:

    • A.

      Set of wires

    • B.

      Set of circuits

    • C.

      Large number of cells

    • D.

      All of these

    Correct Answer
    C. Large number of cells
    Explanation
    Memory is made up of a large number of cells. These cells are responsible for storing and retrieving data. Each cell can store a bit of information, which can be either a 0 or a 1. The cells are organized in a way that allows for easy access and retrieval of data. Therefore, the correct answer is "Large number of cells".

    Primary memory stores:

    • A.

      Data alone

    • B.

      Programs alone

    • C.

      Results alone

    • D.

      All of these

    Correct Answer
    D. All of these
    Explanation
    Primary memory, also known as main memory, is responsible for storing data, programs, and results temporarily while the computer is running. It is directly accessible by the CPU and is used to store instructions and data that the CPU needs to process. Therefore, the correct answer is "All of these" as primary memory stores data, programs, and results.

    Which device can understand the difference between data & programs?

    • A.

      Input device

    • B.

      Output device

    • C.

      Memory

    • D.

      Microprocessor

    Correct Answer
    D. Microprocessor
    Explanation
    A microprocessor is a device that can understand the difference between data and programs. It is a central processing unit (CPU) that executes instructions and performs calculations. The microprocessor is responsible for processing data and executing programs, making it capable of distinguishing between the two. Input and output devices, on the other hand, are used for inputting and outputting data respectively, while memory stores data and programs but does not have the capability to differentiate between them.

    The cabinet containing the computer’s working parts is known as the:

    • A.

      Workstation

    • B.

      System unit

    • C.

      Local hard drive

    • D.

      None of the above

    Correct Answer
    A. Workstation
    Explanation
    The cabinet containing the computer's working parts is known as the workstation. This is because the workstation is typically a physical unit that houses the computer's components, such as the motherboard, processor, memory, and storage devices. It is where the computer's processing and data storage takes place. The term "system unit" refers to the main body of the computer, which includes the workstation along with other components like the monitor, keyboard, and mouse. A local hard drive, on the other hand, refers specifically to a storage device within the computer, not the entire cabinet. Therefore, the correct answer is workstation.
