IT FUNDAMENTALS EVALUATION EXAM QUESTIONS AND
SOLUTIONS 2025/2026 GRADED A+
✔✔Modem - ✔✔allows your computer to connect to other computers and the Internet by
using an analog phone line.
✔✔Liquid cooling system - ✔✔liquid cooling system inside the case. These cooling
systems use tubes filled with a coolant, connected to a radiator, and a pump to circulate
the liquid coolant through the inside of your computer case
✔✔Heat Sinks - ✔✔metal, usually formed into ridges, and installed on components. The
heat sink transfers the heated air from the component to the fan (or liquid cooling
system), which then moves the heated air out of the computer case, keeping the inside
of the case and the components cooler.
✔✔Port - ✔✔hardware interface that you can use to connect devices to a computer
✔✔Serial Connection - ✔✔is a personal computer connection that transfers data one bit
at a time over a single wire. Serial connections support two-way communications and
were typically used for devices such as fax cards or external modems
✔✔Parallel connection - ✔✔parallel connection is a computer connection that transfers
data eight or more bits at a time over eight or more wires. Any components connected
by multiple data pathways may be considered to have a parallel connection.
✔✔USB - ✔✔connection is a computer connection that enables you to connect multiple
peripherals to a single port with high performance and minimal device configuration.
✔✔FireWire - ✔✔connection is a computer connection that provides a high-speed
interface for peripheral devices that are designed to use the Institute of Electrical and
Electronic Engineers (IEEE) 1394 standard
FireWire 400 transmits at 400 Mbps
✔✔USB 3.0 - ✔✔USB 3.0, also called SuperSpeed USB. It features a maximum
transfer rate of 5.0 Gbps.
✔✔USB 2.0 - ✔✔It can communicate at up to 480 Mbps.
✔✔Firewall vs USB - ✔✔USB 2.0 is faster by the numbers than FireWire, FireWire is
actually faster on throughput, making it ideal for video/audio file transfers and external
storage devices.
✔✔External SATA (eSATA) - ✔✔it provides a connection for external storage devices.
eSATA connections provide fast data transfers without having to translate data between
, the device and the host computer. eSATA interfaces do require an additional power
connector to function.
✔✔RJ-45 (registered jack 45) - ✔✔An 8-pin/8-position plug or jack is commonly used to
connect computers onto Ethernet-based local area networks (LAN).
✔✔RJ-11 - ✔✔RJ-11 connector is used with Category 1 cables in telephone system
connections and is not suitable for network connectivity
✔✔Peripheral Devices - ✔✔device that connects to a computer to expand the
computer's functionality. This includes devices that enable the user to input, output,
store, and share data.
✔✔Input devices - ✔✔keyboards, pointing devices, game controllers, scanners,
microphones, webcams, graphics tablet (page 34)
✔✔Output devices include: - ✔✔monitors, printers, speakers (page 37)
✔✔Types of printers - ✔✔Laser, Inkjet, and thermal.
✔✔Output. Types of display devices - ✔✔CRT, LCD, LED,OLED, Plasma, Projector
(page 39)
✔✔Devices that do Input and Output functions - ✔✔Fax, Flashdrive, External hard
drive, Optical discs, Network attached storage, Memory card, Mobile media,
Smartphone, touch screen monitors
✔✔Operating Systems - ✔✔software package that enables a computer to function. It
performs basic tasks, such as recognizing the input from a keyboard, sending the output
to a display screen or monitor, and controlling peripheral devices such as disk drives
and printers
✔✔Types of software licensing - ✔✔Open source, Freeware, Commercial, Copyleft,
Shareware
✔✔Type of Operating Systems - ✔✔Windows, Mac OS X, Linux, Chrome OS (page 46)
✔✔Types of Mobile Operating Systems - ✔✔Android OS, BlackBerry OS, Firefox OS,
Windows Phone OS
✔✔Drivers - ✔✔A driver is specialized software that controls a device attached to a
computer
