WGU D322 - Introduction to IT(D322 - Introduction
to IT) Exam Questions With Well Elaborated Solutions
Web Developer - ANSWER -Builds and maintains websites and their
infrastructure. Need to understand client-side, server-side, and database
web technologies.
Software Tester - ANSWER -A person who is responsible for creating,
documenting, and executing manually created test plans and procedures
relating to system anomalies.
Technical Sales - ANSWER -IT professionals in the role of sales or
account managers identify and help clients adopt IT services or
techniques.
Data Pyramid - ANSWER -It is a concept that visualizes the data-
information-knowledge-wisdom hierarchy.
Information - ANSWER -A collection of data from a variety of sources.
Data is continually aggregating and is not useful until it has been
processed and is presented in a usable form. Information can be
unstructured or structured, and the key term associated with it is
meaning
Data - ANSWER -Includes raw facts or observations.
Knowledge - ANSWER -It is hard to define. It is a dynamic
combination of experience, values, and contextual information. The key
term associated with knowledge is "context"
,Wisdom - ANSWER -it is knowing the right thing to do.
IPOS (Input-Process-Output-Storage) - ANSWER -The IPOS model
explains what computer systems are used for. They take input, process
it, and provide an output while using storage to keep intermediate and
final results of the transformation of data. Individual hardware
components support the function of computer systems.
Three basic computer components - ANSWER -CPU, storage, and
peripheral devices
CPU (Contract Processing Unit) - ANSWER -The CPU supports data
processing. The CPU is the electronic circuit responsible for executing
computer program introductions.
Computer Memory - ANSWER -Stores ephemeral programs and data
in use temporarily for quick access and primarily store it in RAM
(Random Access Memory)
Peripheral Devices - ANSWER -It supports the input and output
operations of the system.
Three parts of CPU - ANSWER -ALU (Arithmetic Logic Unit),
Control Unit, and Processor Register
Arithmetic Logic Unit (ALU) - ANSWER -It contains circuitry that
performs on data. Such as addition and subtraction
Control Unit - ANSWER -It contains circuitry coordinating the
machine's activities
, Processor Register - ANSWER -It contains data storage cells called
registers
Registers - ANSWER -They serve as temporary holding places for data
being manipulated by the CPU. It holds the inputs to the ALU and stores
the results.
Memory Address Register (MAR) - ANSWER -Holds the memory
location of data that needs to be accessed.
Memory Data Register (MDR) - ANSWER -Holds data that is being
transferred to or from memory
RAM (Random Access Memory) - ANSWER -Sometime referred to as
primary or main memory. When the computer is off the data will be lost.
ROM (Read Only Memory) - ANSWER -A component that stores
instructions for crucial system activities, including booting up the
systems and initializing different computer components.
Bus (or Bus Lines) - ANSWER -The wires that serve as electrical
roadways, transmitting information between CPU and other components.
Three types of Bus - ANSWER -Address bus, data bus, and control bus
Address Bus - ANSWER -Carries the destination address of the data is
assigned to be processed.
