Key Components
Hardware, Software, Data
Information Technology
The technology used in creating, maintaining, and making information
accessible
Information System
Takes in raw data entered by a user or acquired from a data source or
sources (input), deliberately transforms the data into information (process),
and provides the results of the transformation to the user (output)
IT department in an organization
IT is responsible for the storage, processing, and distribution of information.
Networks
,Organization servers and give employees access to the resources, the data,
and the exchange of networks.
Infrastructure
The system of hardware, software, facilities, and service components that

Difference between input, output, and storage
*Input: hard disk is inserted into the computer to store information in the
computer
*Output: displays information in a pictorial form allowing the user to interact
directly with the computer
*Storage: Random Access Memory (RAM) holds programs and data when the
computer is in use
Core of Components of IT Hardware
Hard Disk, Monitor, Motherboard, CPU, RAM
Software Development
Implementing various algorithms that transform data into another, which
performs calculations, manipulate files, or complete other repetitive tasks,
can be time-consuming or dangerous to an employee.
Business Analysis
,*Organizations improve their operations by optimizing their technology
*IT changes rapidly, so organizations must constantly investigate and plan or
replace systems.
Information Systems Requirements and needs
*Security: Organizations try to aim for secure systems to prevent incidents
that can disrupt business. Unauthorized access could cause data loss or
modifications
*Accessibility functions: These functions are designed to help people with
disabilities use technology more easily
