6. 1. Hardware Components
 A computer hardware is a physical artifacts
of technology.

11.  Software is a set of instructions and its associated
documentations that tells a computer what to do.
 We classify it into two.
 System software: - System software is software designed
to provide a platform to other software. Example: -
Windows, Linux, UNIX, and etc.
 Application software: - An application is any program, or
group of programs, that is designed for the end users.
 Example: - web browsers, word processors, spreadsheets,
media players, image viewers and etc.

12.  Operating system is an intermediary tool
between computer’s software and hardware
which enables them to interact each other.
 It also enables end users to communicate
with their computer without knowing how to
speak its language.
 Example: - Windows, Linux, UNIX, and etc.

13.  The most common word processor is the
Microsoft office.

- Notepad
- WordPad,
- Microsoft Word,
- Microsoft Excel
- Microsoft PowerPoint
- Microsoft Access
- Microsoft Publisher … etc.

14.  A computer network is a digital telecommunications
network which allows nodes to share resources.
 In computer networks, computing devices exchange
data with each other using connections (data-links)
between nodes.
 These data links are established over a cables’
media such as wires or optic cables, or wireless
media such as Wi-Fi.

15.  Internet is the internetwork connection via all
computers through which users can
communicate directly.
 Browsers are application software which we
interact with others via the internet through
the wire or wirelessly.
