1In a typical desktop PC, which unit is primarily responsible for executing instructions?
A.Central Processing Unit (CPU)
B.Monitor
C.Keyboard
D.Speaker
Explanation: The CPU is the processing component of a computer system. It carries out instructions from programs; the monitor, keyboard, and speaker are peripheral I/O devices, not the main instruction executor.
2Which of the following is best classified as an input device?
A.Printer
B.Mouse
C.Monitor
D.Speaker
Explanation: A mouse sends pointer and click signals into the computer, so it is an input device. Printers, monitors, and speakers deliver output from the system.
3USB ports on a computer are commonly used to connect which of the following?
A.Only the power cord to the wall socket
B.Only the internal hard disk ribbon cable
C.External devices such as a pen drive or keyboard
D.Only the cooling fan to the motherboard
Explanation: USB (Universal Serial Bus) ports let you attach external peripherals such as pen drives, keyboards, mice, and printers. The wall power cord uses a separate power connector, not USB.
4A pen drive is primarily used as which type of storage?
A.Permanent internal ROM chip soldered on the motherboard
B.Optical disc that must be spun by a DVD drive
C.Volatile RAM that loses data when power is removed from the PC
D.Removable USB flash storage for transferring and backing up files
Explanation: A pen drive (USB flash drive) is portable non-volatile storage you plug into a USB port to copy, move, or back up files. It is not optical media and is not the computer’s main RAM.
5When assembling a basic desktop setup, the monitor is normally connected to the:
A.CPU/system unit’s video output (e.g., HDMI/VGA/DisplayPort)
B.Keyboard USB port only
C.Printer parallel port only
D.Speaker 3.5 mm jack only
Explanation: The display cable from the monitor plugs into the video output on the system unit (CPU cabinet), such as HDMI, VGA, or DisplayPort. Keyboard ports, printer ports, and audio jacks serve other devices.
6Which statement best describes a tablet computer compared with a traditional desktop?
A.It has no touch screen and must always use a separate CRT monitor
B.It is a portable computing device that commonly uses a touch screen for input
C.It cannot run any applications and is only a calculator
D.It always requires a separate keyboard and mouse and cannot use touch
Explanation: Tablets are portable devices that typically combine a touch-screen display with computing functions. Desktops usually use a separate monitor, keyboard, and mouse.
7Which of the following is an example of an output device?
A.Scanner
B.Microphone
C.Printer
D.Webcam
Explanation: A printer produces printed output from the computer. Scanners, microphones, and webcams capture information into the system and are input devices.
8The power cord of a desktop computer is used to:
A.Transfer files between two pen drives without electricity
B.Connect the mouse wirelessly to the printer
C.Encode emails before they are sent
D.Supply electrical power from the mains to the system unit / power supply
Explanation: The power cord delivers mains electricity to the computer’s power supply so the system can run. It is not a data cable for file transfer or networking.
9Which component is commonly called the “brain” of the computer because it processes data and instructions?
A.CPU
B.Hard disk enclosure fan
C.UPS battery only
D.VGA cable
Explanation: The Central Processing Unit (CPU) processes instructions and data. Fans cool hardware, UPS batteries provide backup power, and VGA cables carry video signals.
10Connecting a keyboard and mouse to a modern PC is most commonly done through:
A.HDMI video ports only
B.USB ports (or wireless receivers that use USB)
C.RJ11 telephone wall jacks only
D.Optical S/PDIF ports only
Explanation: Modern keyboards and mice typically connect via USB ports, or via a USB wireless dongle. HDMI is for video; RJ11 is telephone; S/PDIF is digital audio.
