Information Technology - a system comprising independent parts that work together to
advance an organization's goals & vision by increasing growth, profits, and productivity.
3 Components of an IT System - Hardware, Software, and People.
IT - technology used to create, maintain, and make information accessible using systems
for information storage, retrieval, and exchange.
System - a collection of elements that interact to achieve a common goal.
Networks - support communication between the elements of an IT system.
Hard Disk - a disk on which information is saved and stored in the computer even when it is
not connected to a power supply.
Monitor - an output device that displays information in pictorial form, allowing the user to
interact with the computer interface and open programs, typically using a keyboard and
mouse.
Motherboard - one of the most essential parts of a computer system that holds many of the
crucial components of a computer, including connectors for input and output devices.
Central Processing Unit (CPU) - a control center that converts data input to information
output and executes stored program instructions.
Random Access Memory (RAM) - the memory within a computer that holds the running
programs and data when the computer is in use.
Network Cables - connect and transfer data & information between computers.
Wifi Routers - transmit, receive, and decode information sent using radio waves.
,Laser Printers - use a laser to form a pattern of electrostatically charged dots on a light-
sensitive drum, which attracts toner; the toner is transferred to a paper and is fixed by a
heating process.
Internet - resources available for the public.
Intranet - resources only available for users or systems of a specific organization.
Extranet - makes resources available within an organization, but it also makes that
information available to other specific organizations or users, such as contracted, third-
party consultants.
Computing - any activity that uses a computer to manage, process, or share information.
