Introduction to Basic Computer Technology

Computing DevicesClick to read  

In the recent past the vast majority of people used a Personal Computer (PC) to access the Internet. Recently however the number of people using only a PC to browse the internet has declined rapidly. 
An ever expanding number of devices are now used to connect to and use the Internet. Some of the most popular computing devices are outlined in the few slides.

Desktop PC with Speakers

Personal Computer
Traditionally the PC was the most popular method used to browse the Internet. 
The Desktop version of a PC is a relatively large device and usually has a monitor, a mouse and a keyboard attached.



A laptop is simply a smaller version of a Personal Computer and has a built in monitor, keyboard and mouse. A laptop may also have built in speakers and microphone.
It is much easier to transport a laptop than a desktop and as a result laptops are more popular than PC’s.



A tablet is a small, thin, flat tablet-sized personal computer which has many of the features of a full-size computer. 
While tablets have been around for quite a while, they have not been widely used in business or in the home. However, the release of the Ipad has made tablets a household name.


The Monitor

The monitor is attached to the systems unit but is not permanently connected, it can be moved from one computer to another quite easily. 
Flat screen monitors come as standard and their function is to display the activity of the computer.


Mouse and Keyboard

Other necessary hardware includes the mouse and the keyboard. 
The mouse is used to enter commands into the computer and the keyboard is used to type information and commands into the computer.


Introduction to Software, Microsoft Word & Excel

SoftwareClick to read  

Software is the term given to the programs used by a computer, for instance if you have a game on your computer, the game is considered software.  If you were to buy a computer with absolutely no software loaded you could not use the computer for much more than a door stop. The usefulness of your computer increases as you add more software.
For now we will consider 2 types of software, Application software and Operating System

Application Software:
Application software is software that allows the user to do specific actual work such as typing letters, creating spreadsheets and databases etc. 
Examples of application software are Microsoft Word (used to type letters), and Microsoft Excel (used to create spreadsheets) and Internet Explorer (used to browse the web).


Operating SystemClick to read  

Most application software cannot communicate directly with hardware, it needs a middle man to translate and communicate between the two items. 

This middle man is known as an operating system, it sits on top of the hardware and facilitates communication with the Applications software.

The most well known operating system for home users is Windows and the most recent version of Windows is Windows  10

Previous versions included Windows Vista and Windows XP
