Computer peripherals are those devices that act as I/O devices and used for operating the computers. There are so many computer peripherals are available in the market used for different types of tasks according to the users requirement or task needs. Some commonly used computers peripherals can be mouse, keyboard, joysticks, monitors and speakers. But, if we go in the depths so there will be enough to describe. Lets start a job with some of useful computer peripherals that are necessary to be used!
Headphones are basically two sided micro-speakers used for hearing sounds from computers. Historically, first headphone was designed for US Navy by Nathaniel Baldwin but later it goes to public after the war. Headphones are divided into two main parts:
Joystick is computer peripheral used mainly for gaming but there are some other uses are available. Joystick was firstly invented by a German scientist Ralph H. Baer in 1944; he was also the founder of computer games.
Keyboard is a set of keys used to operate or input the data in the form of alphabets, numbers and symbols. Keyboard has basically more functions because it has more than 100 operational keys from A to Z, 0 to 9, F1 to F12 and some other operator keys like + – / * @ # %
Monitor is a peripheral device that is used to display the signals from computer by receiving directions from CPU. Some years ago, we used the computer monitors with CRT technology like TV but today they are converted into LCD and Plasma technology which is sharp to see and slim in size. Some common brands for monitors are Samsung, HP, IBM, Dell and Phillips.
Mouse is basically a pointing device used for pointing the features on computer screen and drop them where is necessary. It is considered as one of the useful peripheral devices because it has more reliability of task than keyboard. Mouse varied according to the wires, wirelesses, optical and ball functions.
Speakers are peripheral devices used for outputting sounds via 3.5mm sound jack and sometimes external powers. Speakers are transducers that convert electromagnetic waves into sound waves and used according to your sound needs from low to high. Computer standardized sound systems are varied according to speakers like 2 means 2 speakers, 2.1 means 2 speakers and 1 subwoofer, 5.1 means s speakers and 1 subwoofer. Speakers are relied on sound cards of your computers that are also 2.1, 5.1, 7.1 and 12.1.
All of the Types of Computer Peripherals have important role regarding their processing powers and task that have assigned. These computer peripherals made our lives easy than we ever thought like some other useful computer peripherals are light pen, web cams and USB hubs.
