Keyboards are external input devices used to type data into computers and include alphabetic, numerical, and symbol keys. They connect to devices via serial or USB ports. Mice are also input devices that send click information to computers and offer an alternative to keyboard interaction. Typical mice have two buttons and a scroll wheel. The motherboard connects all computer parts like the CPU, memory, drives, and ports and acts as the computer's backbone. Processors are microchips that process instructions from software and come from manufacturers like Intel and AMD, with higher gigahertz capacities providing faster processing. Printers are external devices that take computer data and print hard copies of text, images, and photos. Speakers receive audio input from sound cards
2. Keyboard
External input device used to type data into some sort of computer
system whether it be a mobile device, a personal computer, or
another electronic machine. A keyboard usually includes alphabetic,
numerical, and common symbols used in everyday transcription. Keyboards
for personal computers are connected to the machine through serial or
USB plugs.
3. Mouse
The computer mouse is considered an input device. With a click of a button,
the mouse sends information to the computer. The computer mouse is an
interesting device that offers an alternative way to interact with the computer
beside a keyboard.
typical mouse has two buttons. At the top of the device you will find a left and
right button which allows for “clicks”. There is a scrolling wheel between the
two buttons.
4. Motherboard
The motherboard serves to connect all of the parts of a computer together. The
CPU, memory, hard drives, optical drives, video card, sound card and other
ports and expansion cards all connect to the motherboard directly or via
cables.
The motherboard is the piece of computer hardware that can be thought of as
the "back bone" of the PC.
The Motherboard is also known as
mainboard, mobo (abbreviation), MB (abbreviation), system board, logic
board.
5. Processor
Microchip implanted in a CPU's hard drive that processes instructions sent to
it by the computer and software programs. Processors come in a number of
sizes and are manufactured by such corporations as Intel and Advanced Micro
Devices. The greater the gigahertz capacity of the processor, the quicker the
computer will be able to process instructions sent to it. Some corporations
have developed a dual processor, which allows one processor to process
multiple instructions at the same time without slowing down performance.
6. Printer
A printer is an external hardware device responsible for taking computer data
and generating a hard copy of that data. Printers are one of the most used
peripherals on computers and are commonly used to print text, images, and
photos.
7. Speaker
Speakers are popular output devices used with computer systems. They receive
audio input from the computer's sound card and produce audio output in the
form of sound waves. Most computer speakers are active speakers, meaning
they have an internal amplifier which allows you to increase the volume, or
amplitude, of the sound. Speakers usually come in pairs, which allows them to
produce stereo sound from two separate audio channels.
8. HeadPhone
A hearing device usually used for mp3 players, laptops, portable DVD players,
and things of that nature
they are normally used at times when the people around you don't want to hear
what ever you are listening to.
9. Data Cable
Data cables are an important part of a computer, as they provide a
connection between various hardware components. This enables a
computer to communicate with its own various parts. A data cable also
enables a computer to communicate with additional computers.
10. Webcam
A webcam is a digital camera that’s connected to a computer. It can send
live pictures from wherever it’s sited to another location by means of the
internet. Many desktop computer screens and laptops come with a built-in
camera and microphone, but if yours doesn’t, you can add a separate
webcam at any time.
