The difference between input and output, and types of computers.

the difference between input and output devices is very simple, An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device.

examples of input devices :

1- Keyboard

2- Mouse

examples of output devices ;

1- Monitor

2- Speakers

The process involving of getting data into computer :

Collecting - First step is to collect the raw data which you want to process. From which data do you want information? This is first question before you start.

Sorting - Relevance of data is very important while processing the data. There are various irrelevant data which decrease the perfection of the information. So from the bunch of collected data, sorting is needed to get relevant output information. Data must be in proper categorization.

Bucketing - It is similar to 'netting' or 'coding'. This step involves aligning the random data in particular structure. When data collected and sorted, it was not aligned properly. Random data can create problem while processing the data. Bucketing helps you to have the process smoothly.

Entering Data - If system is not having any data, what it process!! To process data, there must be data for the software. Entering organized data in to the software is required to get processed information at the end of whole process.

Cleansing - This step increase the quality of the processed data. In this step, quality controller validates the data. Data is double-checked to secure the faultless data processing. This cleansing helps you to process the data very efficiently and quickly.

Proper Formatting - Last but most important step to end the process very effectively is proper formatting. Without proper formatting, there is no meaning of data processing. Proper formatting is very much helpful to understand the data very easily and conclude the decision quickly.

the final point of this post is types of computers

Computers can be generally classified by size and power as follows, though there is considerable overlap:

• Personal computer: A small, single-user computer based on a microprocessor.

• Workstation: A powerful, single-user computer. A workstation is like a personal computer, but it has a more powerful microprocessor and, in general, a higher-quality monitor.

• Minicomputer: A multi-user computer capable of supporting up to hundreds of users simultaneously.

• Mainframe: A powerful multi-user computer capable of supporting many hundreds or thousands of users simultaneously.

• Supercomputer: An extremely fast computer that can perform hundreds of millions of instructions per second.
