abstract. Good day!! Welcome!!. Do you ever wonder how your computer works? Well, hop on as we tackle the basic parts of a Computer.

Our objectives in this lesson. Define what is a c omputer Identify the major components of a computer Give example of the hardware and software components of a computer Differentiate between input and output devices of a Computer.

But first….What is a computer?. A Computer is a digital electronic machine that can be programmed to carry out sequences of arithmetic or logical operations automatically. Modern computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks..

Who is the father of the computer. Charles Babbage was an English polymath. A mathematician, philosopher, inventor, and mechanical engineer, he originated the concept of a digital programmable computer..

Two major components of a computer. abstract. Software-the intangible components of a computer. It is the electronic instructions that tell the computer what to do. Examples: Application software-lets you accomplish specific tasks. i.e. word, excel, publisher.

Software components. Operating System- sets rules for how computer hardware and application software work together. i.e. Windows XP, Windows 7, Windows 10.

What are input and output devices?. Input device- a computer hardware that accepts data and instructions from the user. Examples: Light pen Keyboard Mouse Joystick Microphone Scanner Camera.

What are input and output devices?. Output device- a hardware component that returns processed data to the user. Examples: Monitor Printer Speakers Headphone Projector.

How do a computer process data?. Processing- it is the procedure that transforms raw data into useful information. Central Processing Unit- the brains of the computer; process instructions, performs calculations and manage the flow of information Examples: Intel AMD.

What is storage?. Storage- the portion of the computer that holds data or programs while they are not being used. Examples: Hard drive Floppy disk CD-ROM Servers DVD Other storage-USB, External Hard drive, Memory Card.

Well done class, that sums up our discussion for today!!.
