Answers | Graded
Infrastructure- the underlying foundation or basic framework of
something. (It’s the backbone that a business is built on)
Information Technology- the study, design, development, implantation,
support, and management of computer-based information systems
(particularly software and hardware)
Paradigm Shift- an important change that happens when the usual way
of thinking about or doing something is replaced by a new and
different way.
6 Components of Information Technology (IT): These all work together
to provide the connectivity and collaboration necessary for businesses
to utilize IT, but each component cannot stand alone.
1. Hardware: makes up the physical part of a computer (CPU,
motherboard, keyboard, disk drives)
2. Software: set of computer instructions that tell the computer
how to perform tasks
a. Application: software that a user chooses that
accomplishes a specific task for the user.
b. Utility: performs background tasks to analyze and
maintain computer with little to no interaction from the
user
c. System: supports a computers basic function such as
scheduling tasks, executing applications, controlling
peripherals. (operating system)
3. Networks: consists of two or more devices such as routers,
switches, and communication links that allow the computer
systems to communicate with each other no mater the
distance “Backbone of IT”
4. Data: after finances; data is a very valuable asset a company
can acquire. Its information held in databases for different
purposes.
5. People: key to an IT infrastructure. Can be anyone from IT
gurus to someone that uses the system to perform their daily
functions.
6. Process: the final component of IT Infrastructure. Functions
the end user performs in their daily business.
Why is IT competency important? Knowledge of a company’s
computing system and its relationship to business provides a
,company efficiency, cost savings, and improved customer
service.
IT Best Practice- a management process, technique, or method that
is most effective in arriving at a desired or better outcome than
anything else.
Leverage- to use something to its maximum value
How can IT “Leverage” a business to gain a competitive
advantage?
By having computer competency and applying information
technology.
Moore’s Law- states that computing power doubles every 18
months.
Hypertext Markup Language (HTML) used to create web pages
Hypertext Transfer Protocol (HTTP) used to define how messages
are formatted and transmitted on the internet.
Routers- forward information throughout a network
Switches- filter the information to the correct part of network
Hub- are common points of connection on a network
Client/server- information is stored in a central location
Mainframe Computers- massive room-sized computers that process
and store enormous amounts of information.
Midrange Computers- (sometimes called minicomputers) less
powerful and smaller in physical size but does the same as a
mainframe computer, but on a smaller scale. Minicomputer does
the same as mainframe but on a smaller scale.
Microcomputers (laptops, desktops, handheld) small computer
unable to process large amounts of data or transactions.
, Operating System (OS)- often called “platform” is a collection of
computer programs that work together to manage hardware and
software to ensure they work properly.
Graphical User Interface (GUI)- the visual system of a computer
screen design that allows a user to interact with electronic devices
(the computer screen)
Computer process- any task a computer performs.
Central Processing Unit (CPU)- the “brains” of the computer and it
executes instructions required by the software.
Motherboard- all the internal devices connect to the motherboard;
it has circuits printed on it that provides pathways for data to be
exchanged between all the components connected to it.
Peripheral Devices-equipment that reside outside the computer like
printers, scanners, and are connected to the computer via USB
connection
Cache- a hardware or software component the CPU stores
frequently used data for faster access.
Random Access Memory (RAM)- memory that allows data to be
accessed in any order without physical movement of the silicone
media.
Registers- (smallest and fastest type of memory) built into the CPU
itself for a specific purpose and has quick access time.
Virtual Memory- a section of a hard disk that mimics RAM. Appears
to exist in main storage but most of the memory is supported by
data held in the secondary storage, transferring data as required.
Solid-State Drive (SSD)- a storage device that uses integrated
circuit assemblies as memory to store data persistently, typically by
using flash memory.
