Now let's get in to the computer:

The computer is broadly divided into to 2 major categories:

1. Hardware
2. Software

In this blog we'll discuss in detail on the hardware part of the computer.

Hardware:

It is the physical device, refers to the tangible (things that you can feel, touch) components of a computer system.

Hardware components are further divided into 3 groups:

1. Input devices
2. Output devices
3. System unit

1. Input device : An input device lets you communicate with the computer. You can use input devices to enter information and issue commands.
Example:

• Keyboard: Is a standard input device of most computers, used to type data into the computer.
• Mouse: Is a Hand-clicked device used for pointing and moving objects
• Joystick: is an input device used for playing computer games.
• Track Ball:Its an upside down mouse used for precision movement and pointing accuracy or for people with motor disability.
• Light pen: is a device used to draw write, or issue commands when it touches a specially designed screen.
• Scanner: a scanner allows you to scan documents, pictures, or graphics and view them on the computer, it a device that helps to convert hard form of the media to digital form that could be easily sent through email or other digital modes.
• Microphone: Used to input sound into a computer.

2. Output device: An output device displays information on a screen, creates printed copies or generates sounds.
Example:

• Printers: Is a device that produces text and or graphics on paper or any printable material.
• Monitor: Is a device that provides digital output on a screen.
• Multimedia Projector: is a type of video projector for displaying video, images or computer data on a screen or other flat surface.
• Speaker: it plays sound transmitted as electrical signals from the sound card.

3. System Unit: The system unit is the part of the computer which is responsible for accepting and processing the data brought in by the input devices
Example:

• Motherboard: It is the main circuit board of a computer. It is also known as mainboard or system board.
• IDE: Integrated device Electronics is a standard interface for connecting a motherboard  to storage devices such as hard drives and CD-ROM/DVD drives. The initial IDE had a 16-bit interface that connected two devices through a single-ribbon like cable.
• SATA: Serial Advanced Technology Attachment or Serial ATA: Is an interface used to connect ATA hard drives to a computer's motherboard.
• Hard Disk Drive: Is an electromagnetic non removable storage device that is used to stores and retrieve billions of characters of data. It is attached to the motherboard of a computer.
