WGU- D322 INTRO TO IT EXAM WITH
CORRECT ACTUAL QUESTIONS AND
CORRECTLY WELL DEFINED ANSWERS
LATEST ALREADY GRADED A+ 2025 - 2026
Network hub - ANSWERS-device that connects multiple computers together
Network switch - ANSWERS-more functional connection than a hub, its
purpose is to only send transmissions to a specific, intended computer.
Router - ANSWERS-device that connects multiple networks together
Wireless access point - ANSWERS-connected to a hub, a switch, or a router.
This device then sends out a wireless signal so computers on the network can
connect without a cable
Radio waves - ANSWERS-provide access to networks over long distances
IP address - ANSWERS-a series of numbers that indicates a specific internet
location
,Server - ANSWERS-computer that takes requests and responds with the
requested information
Network Types - ANSWERS-Bus Network
Mesh Network
Ring Network
Star Network
Define Information Technology - ANSWERS-IT is a term used to describe
several aspects: the task of gathering data and processing it into information,
the ability to disseminate information using technology, the technology itself
that permits these tasks, and the collection of people who are in charge of
maintaining the IT infrastructure (the computers, the networks, and the
operating systems). Generically, we will consider IT to be the technology used
in creating, maintaining, and making information accessible. In other words,
IT combines people with computing resources, software, data, and computer
networks
Information technology - ANSWERS-describes the technology infrastructure
that may support information systems, although Information Technology
could also support many other types of systems (e.g., telecommunications
systems). Information Technology includes hardware, software, networks,
and databases that work together to allow an organization to manage data
and information.
A computer performs four operations - ANSWERS-IPOS
Input
Processing
Output
, Storage
Parts of the CPU - ANSWERS-ALU
Control Unit
Registers
Memory - ANSWERS-SCRAM
DRAM
ROM
I/O Subsystem - ANSWERS-Input Devices
Output Devices
Storage Devices
Computer structure - ANSWERS-{CPU (ALU, Control Unit, Registers)
System Bus
Memory(SCRAM, DRAM, ROM)}
I/O Bus
{I/O Subsystem (Input Devices, Output decides, Storage Devices)}
CPU (Central Processing Unit) - ANSWERS-is the device that not only executes
your programs' instructions, but also commands the various components in
the computer.
Memory - ANSWERS-stores the program(s) being executed and the data that
each program is using.
