- 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: Petabyte248. The box that contains the central electronic components of the computer is the ___________________?
- 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.
Correct answer: digital modulation
