Printers can be classified on a number of parameters like: mechanism used for printing, the speed of printing, the quality of output and the direction of printing. There are 2 types of printers: 1) Impact Printer- Feature- Characters are printed by pressing a typeface against an inked ribbon so that it makes a mark on the paper. Example- Dot-matrix is a type of impact printer. These printers are not commonly used these days. 2) Non-impact Printer- Feature- There is no contact between the typeface and paper while printing. They don't create noise while printing because their printing heads do not strike the paper. Example- 1. Laser Printer- It uses a beam of light to form images and print characters on the paper using toner ink as a medium. 2. Inkjet Printer- It uses jets of ink to print characters on paper. It consists of cartridges of 3 colours- magenta, yellow and cyan inks to create colour tones. These printers are commonly used these days.

accountname @ domain.com
1) Domain name: This part of the email address is the name of server that hosts your emails. It is not necessary that the domain name would always be of a .com kind. It can be anything from the standard list of domain extension (e.g. .org , .net , .gov, .co.in etc.)
A server could that be of a free web-based email service provider (like Gmail, Hotmail, Yahoo! Mail etc.) or server may belong to a specific organization (for example, if you’re working in a company named XYZ … the server name could be xyz.com)
2) Account name (or username): An email hosting server may host emails for one person —or millions of persons.
3) @ Sign: First thing first, in case of email address, this symbol is pronounced as at and not as “at the rate”
This symbol is used in an email address to separate account name from domain name. When a computer tries to understand an email address, it splits the address from @ sign. The part of email address that comes before @ is account name and the part that comes after it is domain name.

Computer: A computer is a combination of hardware and software resources which integrate together and provides various functionalities to the user. Hardware are the physical components of a computer like the processor, memory devices, monitor, keyboard etc. while software is the set of programs or instructions that are required by the hardware resources to function properly.
There are a few basic components that aids the working-cycle of a computer i.e. the Input- Process- Output Cycle and these are called as the functional components of a computer. It needs certain input, processes that input and produces the desired output. The input unit takes the input, the central processing unit does the processing of data and the output unit produces the output. The memory unit holds the data and instructions during the processing.
