What are four different types of peripherals?

What are four different types of peripherals?

The peripheral is a device of a computer system that performs a single task on the computer system to provide the service to the end user and the user get the solution from the computer system on the different types of department for solving the problem on the computer system.

The peripheral also included and installed or manufactured inside the CPU cabinet to perform a task according to the CPU instructions that the CPU gives the instructions to the peripherals and they performs a specific task such as:- bus is used to transfer the data to the different types of peripherals, ram is used to store temporary data or files, permanent memory is used to store the data for long time to access that means the permanent memory stores permanently if the user cannot delete or remove by format the permanent memory device of the computer system.

Similarly, the external peripherals are the devices that are connected outside of the CPU cabinet of the computer system. Such as:- input devices are keyboard, mouse, microphone etc. And the output devices are speakers that provide sound data, printer output devices are used to provide hardcopy of documents, and monitor output devices are used to provide display data on screen.


Introduction to the computer system related topic and the topic is following below here:


What are four different types of peripherals?


Let's discuss the computer system related topic is mentioned above and the explained following below here:


What are four different types of peripherals?

There are some points on the computer system and peripherals and hardware of computers related to the topic of "What are four different types of peripherals?" following below here:


What are four different types of peripherals?

  • The monitor output device is used to display data
  • Speaker is used to provide audio output data
  • Keyboard input device is used to provide text data to computer
  • Microphone is used to input audio data to computer


Let's discuss the points listed above about the computer system and peripherals related to the topic of "What are four different types of peripherals?" explanation following below here:


The monitor output device is used to display data

The monitor output device is used to display data on the computer system and also shows the activities done by the end user on the operating system in GUI form or application software. The user can see the response back to the end user when the user gives instructions to the application software then the application responds back to the user through the monitor output device in the display form and the end user understands the application software design interface for how to operate the application software on the computer system.

The monitor output device is used to display three types of data:- text data, image data and video data.

Monitor displays the activities of the users on the screen according to the application software.

The monitor output device is used to provide the display of all types of output data except audio data on the computer system but the audio file can be displayed on the screen of the monitor output device.


Speaker is used to provide audio output data

The speaker is an output device that provides the audio output data to the end user on the computer system from the application software which is used to send the output data to the speaker output hardware resource.

The speaker is used to provide the microphone input data and it is processed on the application then provided through the speaker output device of the computer system.

The speaker is used for listening to music file, video file audio data which is to understand the video data file when the end user watches on the screen of the monitor output device and the speaker is used to provide the sound data to the end user to understand the video data by hearing the sounds, dialogues, music etc. Through the speaker output device on the computer system.

The speaker output device is also used for communication purposes because the audio data is used to hear and talk to the connected user on the voice call, voice chat, audio clip sending messages etc.

Similarly, the video call is used to display the face and audio data through the speaker output device during the video call on the communication application software.


Keyboard input device is used to provide text data to computer

Keyboard input device is used to provide the text data to the computer system that means the keyboard input device is used to send the input data in the form of keys instructions and it is depends on the application types that means if the application software is used for creating document file then the keyboard input device is used for providing the text data in the document file to type the text data in the form alphabets with collection and combination of the keys from the keyboard input device.

The keyboard input device is used to provide the service of typing words to enter the text information into the particular form, document application file, program typing, database store, rename files etc.

The keyboard also gives instructions to the application software to operate the options and application to get the solution from the application software to the end user through the output device of the computer system.


Microphone is used to input audio data to computer

Microphone is used to input audio data to the computer system that means the microphone is an input device that sends the audio input data to the computer system and an application software which is used to compute the audio data is used to process and saved into the memory device of the computer system or in the permanent memory of the computer.

The Microphone input device is used to provide the input data to the application software to process and provide the output to the speaker when the user wants to hear the audio data coming from the microphone input device.

The microphone input device is used to communicate to the user when the user creates a voice call through the mobile device or computer system using the network device including the sim card or network device to send the voice data to the user to communicate to each other from the microphone input device in the data communication system.

The microphone input device is also used for video calling because the video calling is used to connect with the user through video calling application software to connect the user ID and they can communicate to each other through the video call on the computer system or smartphone device.

Describe the different ways of mobile communication systems for users?

Describe the different ways of mobile communication systems for users? Mobile communication makes it easy to connect with many users through the different types of ways to provide the communication system, share the information to each other and make communication between two or more users through the mobile devices. Such as:- an internet service provides many ways to connect the users in the text, audio, image and video file or data connections sharing the information to each other using these data types to communicate to each other. The user needs to communicate with the other user on the data communication system application software provide the process the data to send the file or message to the user who is connected to the communication application software through their user ID name or email to communicate to share the text or audio file or video file or image file also can be shared into the application software to the user such as:- if the application software provide the chatt...

I am exploring the points on if data centers uses a SAN how it is bigger than SANs?

Is data centers using a SAN and how much are data centers bigger than SANs? The data centers are used to provide the big data analytics for the website and companies to provide the processed data for making different types of informed decisions at a large amount of data processing in the data centers because it is a very big area to install into the building and many buildings if it requires to install into many buildings. The large requirement of data centers installation is necessary because the data centers uses many types of computers, storage devices, network attached storages, network devices such as:- servers, switches, hubs, routers, bridges, repeaters, gateways etc. data cables and different types of network equipment to use in the data centers to make a large area of data processing for the companies uses and major projects for website at larger industrial area for website for data processing. The storage area network is used to provide the high performance of data processing...
