COMPTIA IT Fundamentals UPDATED
Actual Exam Questions and CORRECT
Answers
Computing Device - CORRECT ANSWER✔✔- A computing device is an electronic
machine that uses binary data to automatically perform calculations.
PC - CORRECT ANSWER✔✔- A personal computer, or PC, is a computing device designed
to be used by one person at a time. These computing devices are found in offices, schools,
and homes. PCs are used to run commercial software applications,
desktop computer - CORRECT ANSWER✔✔- A desktop computer is a computing device
designed to be placed on or near a user's desk. Its size and its need to be plugged in to a
power source mean it typically needs to be placed where it will be used and not be moved.
All-in-One Desktop Computers - CORRECT ANSWER✔✔- Some computers have the
monitor and the computing components all in one physical device and are hence referred to
as all-in-one computers
Laptop - CORRECT ANSWER✔✔- laptop is a complete computer system that is small,
compact, lightweight, and portable. All laptops have specialized hardware designed
especially for use in a smaller portable system, use standard operating systems, can run on
battery or alternating current (AC) power
Servers - CORRECT ANSWER✔✔- network computer that shares resources with and
responds to requests from computers, devices, and other servers on the network. Servers
provide centralized access and storage for resources that can include applications, files,
printers, and other hardware as well as services, such as email.
Supercomputer - CORRECT ANSWER✔✔- fastest and the most expensive computer among
all types of computers
Mainframe - CORRECT ANSWER✔✔- large computer that might serve a large
organization. It is used to process and store information for many users at once.
, Motherboard - CORRECT ANSWER✔✔- motherboard is the personal computer component
that acts as the backbone for the entire computer system.
CPU - CORRECT ANSWER✔✔- computer chip where most of the computing calculations
take place
Power supply - CORRECT ANSWER✔✔- internal computer component that converts line
voltage AC power from an electrical outlet to the low-voltage direct current (DC) power
needed by system components
RAM - CORRECT ANSWER✔✔- type of computer memory that can be accessed
randomly; that is, any byte of memory can be accessed without touching the preceding bytes.
volatile memory.
Byte - CORRECT ANSWER✔✔- One character (a letter, number, space, or punctuation
mark). A byte consists of 8 bits.
Kilobyte (KB) - CORRECT ANSWER✔✔- 1,024 bytes or 8,192 bits constitute 1 KB
Megabyte (MB, Meg, or M) - CORRECT ANSWER✔✔- 1,048,576 bytes or 1,024 KB
constitute 1 MB.
Gigabyte (GB) - CORRECT ANSWER✔✔- 1,073,741,824 bytes or 1,024 MB constitute 1
GB.
Terabyte (TB) - CORRECT ANSWER✔✔- 1,099,511,627,776 bytes or 1,024 GB constitute
1 TB
Dual in-line memory modules (DIMMs) - CORRECT ANSWER✔✔- found in many
systems, and they have a 64-bit data path. DIMMs generally have 16 or 32 chips per module.
Small outline dual in-line memory modules - CORRECT ANSWER✔✔- SODIMMs are
most often seen in laptops, small networking devices (such as routers), and PCs with smaller
system boards. They have either 32- or 64-bit data paths. Half the size of DIMM
