  • A. RAM
  • B. Printer
  • C. Monitor
  • D. ROM

Explanation: The monitor displays visual output produced by the computer. RAM and ROM store data, while a printer produces output on paper.

Correct answer: Monitor
  • A. piggybacking
  • B. cyclic redundancy check
  • C. fletcher's checksum
  • D. none of these

Explanation: Piggybacking attaches an acknowledgement to an outgoing data frame instead of sending a separate acknowledgement frame.

Correct answer: piggybacking
  • A. Pictures
  • B. Text
  • C. Both picture and text
  • D. Neither picture nor text

Explanation: A scanner converts both printed pictures and text into digital form. Text may later be made editable through OCR, while an ordinary scan…

Correct answer: Both picture and text
  • A. Dragging
  • B. Dropping
  • C. Right clicking
  • D. Shift clicking

Explanation: Right-clicking an object opens its shortcut or context menu, which commonly includes Properties.

Correct answer: Right clicking
  • A. special function cards
  • B. RAM
  • C. CPU
  • D. Intel

Explanation: The CPU works directly with main memory to fetch instructions and data, process them, and store results.

Correct answer: CPU
  • A. system units
  • B. output devices
  • C. storage components
  • D. Input devices

Explanation: The system unit contains the processor and other core components that process data.

Correct answer: system units
  • A. Gigabyte
  • B. Terabyte
  • C. Petabyte
  • D. Megabyte

Explanation: Among the listed units, a petabyte is the largest: 1 petabyte is 1,024 terabytes in the usual binary-based convention.

Correct answer: Petabyte
  • A. motherboard
  • B. system unit
  • C. peripheral
  • D. input device

Explanation: The system unit is the computer’s case or enclosure containing the motherboard, processor, memory, and other central electronic…

Correct answer: system unit
  • A. Octal digits
  • B. Binary digits
  • C. Hexadecimal digits
  • D. Decimal digits

Explanation: Digital computers represent instructions, numbers, letters, and other data using binary digits, 0 and 1, because their electronic circuits…

Correct answer: Binary digits
  • A. Performs the primary storage function
  • B. Is the only chip cound in most PC models
  • C. Performs the arithmatic-logic and control functions
  • D. Almost always operates on by-bits of data at a time

Explanation: The microprocessor acts as the CPU, carrying out arithmetic and logical operations and controlling instruction execution.

Correct answer: Performs the arithmatic-logic and control functions
  • A. Mainframe computers
  • B. Supercomputers
  • C. Minicomputers
  • D. Microcomputers

Explanation: EBCDIC is an 8-bit character-coding system historically associated with IBM mainframe computers.

Correct answer: Mainframe computers
  • A. Icon
  • B. Screen
  • C. Keys
  • D. Menu

Explanation: The individual letters, numbers, and symbols pressed on a keyboard are keys.

Correct answer: Keys
  • A. computer forensics
  • B. forecasting
  • C. robotics
  • D. simulation

Explanation: Robotics uses computer-controlled machines or devices to carry out physical actions, including highly precise surgical procedures.

Correct answer: robotics
  • A. millions of instructions per second
  • B. multiple instructions per second
  • C. megabytes of instructions per seconds
  • D. millions input processor set

Explanation: MIPS expands to millions of instructions per second, a rough measure of processor instruction throughput.

Correct answer: millions of instructions per second
  • A. Keyboard, monitor and hard drive
  • B. System unit, input / output and memory
  • C. System unit, input / output and secondary storage
  • D. System unit, primary storage and secondary storage

Explanation: The standard three hardware categories are the system unit, input/output devices, and secondary storage.

Correct answer: System unit, input / output and secondary storage
  • A. Scanner, Printer and Monitor
  • B. Keyboard, Printer and Monitor
  • C. Mouse, Printer and Monitor
  • D. Plotter, Printer and Monitor

Explanation: A plotter, printer, and monitor all produce output, so they are output devices.

Correct answer: Plotter, Printer and Monitor
  • A. bridge
  • B. firewall
  • C. router
  • D. none of these

Explanation: A router examines packet destination information and forwards the packet between different networks.

Correct answer: router
  • A. protocol architecture
  • B. protocol stack
  • C. protocol suit
  • D. none of these

Explanation: A protocol stack is the ordered collection of protocols used at the successive layers of a networking model.

Correct answer: protocol stack
  • A. analog modulation
  • B. digital modulation
  • C. multiplexing
  • D. none of these

Explanation: Multiplexing combines multiple signals so they can share one communication channel, with the signals separated again at the receiving end.

Correct answer: multiplexing
  • A. digital modulation
  • B. amplitude modulation
  • C. frequency modulation
  • D. phase modulation

Explanation: Digital modulation represents digital bits by changing an analog carrier's characteristics, such as amplitude, frequency, or phase.
