COMPUTER HARDWARE EXAM 2025
QUESTIONS AND ANSWERS
An output device that is used to create hard copies of things displayed on your monitor. -
ANS Printer
anything that will connect to the outside of the computer, they can be input and output,
depending on the device. - ANS Peripheral
a personal computer designed for regular use at a single location on a desk or table due to its
size and power requirements. - ANS Desktop PC
a portable computer, usually battery-powered, small enough to rest on the user's lap and
having a screen that closes over the keyboard like a lid. - ANS Laptop PC
considered the brain of a computer, which carries out the processing of tasks and instructions
in the computer. - ANS Central Processing Unit (CPU)
a thin board made of fiberglass or other laminate material on which conductive pathways are
"printed", connecting different components on the PCB, such as transistors, resistors, and
integrated circuits. - ANS Printed Circuit Board (PCB)
the main circuit board of your computer which hosts the CPU, the chipset, BIOS chip, RAM
expansion slots, PCI slots, and USB ports etc. - ANS Motherboard

, the time between two adjacent pulses of the oscillator, during which a CPU can perform a basic
operation such as fetching an instruction, accessing memory, or writing data. - ANS Clock
Cycle
a type of volatile memory that can be accessed randomly. - ANS Random Access Memory
(RAM)
a type of non-volatile memory on which data can only be read but not written to. - ANS Read
Only Memory (ROM)
a read-only memory in which a set of routines is stored, enabling a computer to start the
operating system and to communicate with the various devices in the system, such as disk
drives, keyboard, monitor, printer, and communications ports. - ANS BIOS chip
a data storage device that does not use any movable parts and consist of flash memory chips
that store your data. - ANS Solid State Drive (SSD)
a data storage device comprised of a set of stacked "disks," each of which has data recorded
electromagnetically in tracks and sectors on it. - ANS Hard Disk Drive (HDD)
a computer memory that can retain the stored information even when not powered. -
ANS Non-Volatile Memory
a computer memory that can not retain the stored information when not powered. -
ANS Volatile Memory
computers designed with a full set of computer instructions that range from very simple to very
complex and specialized to provide needed capabilities in the most efficient way. -
ANS Complex Instruction Set Computer (CISC)
