Most computer users use PCs, (personal computers). These general purpose computers can be used for pretty much anything, chances are that you are viewing this webpage on a PC right now. Smart Phones can also be considered computers, since they perform computational tasks and have almost all the elements of a regular computer.
Literally, Personal Computers are made for personal use. meaning, this Type computer was designed for end-users. Personal Computers are designed with a user friendly, easy to understand instructions to be able to users to use easily computers without understanding it very much. usually, Personal Computers has normal specs for personal use only, (Chatting, Internet surfing, Gaming, Document Processing...) while General computers are made for Professional users like I.T. for advanced matters (Programming, Advanced Networking). usually, General Computers are used by Large Companies for handling Millions of Transactions like a Telecommunication, Researching and etc.
MAINFRAME COMPUTERMINI-COMPUTERMICRO-COMPUTERSUPER-COMPUTERThere are many computers which are different from each other in various aspects. Classification of computers are given below.(1) Micro computers: These computers use a microprocessor chip and this chip is used instead of CPU means that this microprocessor chip works as a CPU.These computers are also called personal computers. Two major types of these computers are laptop or Desktop computers. Only one user uses these computers at time that's why they are also known as personal computers.(2) Mini Computers: These are powerful computer. These computers come into existence in 1960s at that time mainframe computer was very costly. Mini computers were available in cheap prices, so users start using it.(3) Mainframe Computer: It as a very powerful and large computer. You can get idea of its power as it can handle processing of many users at a time.Terminals are used to connect a user to this computer and users submit there task through mainframe. Terminal is a device which has keyboard and a screen. By using terminal users put inputs into the computer and get the output through screen.(4) Super Computers: As the name "super computer" specifies that these are most powerful computers even than mainframe. Actually, when we optimize a mainframe computer then we get super computer.(5) Microprocessor: You will find these computers everywhere. Microprocessor chips are used in many devices as I-pod, DVD, headphone etc.
The Internet, sometimes called simply "the Net," is a worldwide system of computer networks - a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers).

Instead of punched cards, users interacted with their computers using keyboards, monitors, and operating systems.

People who use the computer are often simply known as "users".
Today, most general or basic computer courses focus users on the social aspects of their computers such as browsing the internet, email, IM, tweeting, Facebook, etc.
Users can communicate to their computer using the keyboard. Another device that can be used to communicate to a computer is the mouse.
•Which computer features are important for particular users? (Doctor, teacher, journalist)
a. About 200b. About 5000 users
An external server is a computer, or series of computers, that link other computers or electronic devices together. They often provide essential services across a network, either to private users inside a large organization or to public users via the internet. For example, when you enter a query in a search engine, the query is sent from your computer over the internet to the servers that store all the relevant web pages. The results are sent back by the server to your computer.
Users of computers want to do things with their computers. Applications are programs that allow people to actually do things with a computer. Almost every program a users uses is an application. Systems software is what makes the computer work. They are needed to make applications work. Users don't really use the system software directly, but rather the applications on their computers. Some applications come with computers, so can be got for free and some need to be purchased. So some users will buy applications for that reason.Users of computers want to do things with their computers. Applications are programs that allow people to actually do things with a computer.

The earlier machines were using the hardwired mechanism to control the function of processes of the computer. Discuss the components of the Von Neumann Architecture that moved the functions of the computers from Special purpose machine to universal (General) machine.
