Dot Matrix Printing

Dot Matrix Printing

Dot matrix printing or impact matrix printing  is a type of computer printing which uses a print head that moves back-and-forth, or in an up-and-down motion, on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper, much like the print mechanism on a typewriter.

A type of printer that produces characters and illustrations by striking pins against an ink ribbon to print closely spaced dots in the appropriate shape. Dot-matrix printers are relatively expensive and do not produce high-quality output. However, they can print to multi-page forms (that is, carbon copies), something laser and ink-jet printers cannot do.





Dot-matrix printers vary in two important characteristics:

>> speed: Given in characters per second (cps),the speed can vary from about 50 to over 500 cps. Most dot-matrix printers offer different speeds depending on the quality of print desired.




>> print quality: Determined by the number of pins (the mechanisms that print the dots), it can vary from 9 to 24. The best dot-matrix printers (24 pins) can produce near letter-quality type, although you can still see a difference if you look closely.

Ransomware Virus NEW VIRUS

About | Ransomware

What is ransomware?Malicious software that locks a device, such as a computer, tablet or smartphone and then demands a ransom to unlock it

Where did ransomware originate?The first documented case appeared in 2005 in the United States, but quickly spread around the world

How does it affect a computer?The software is normally contained within an attachment to an email that masquerades as something innocent. Once opened it encrypts the hard drive, making it impossible to access or retrieve anything stored on there – such as photographs, documents or music

How can you protect yourself?Anti-virus software can protect your machine, although cybercriminals are constantly working on new ways to override such protection

How much are victims expected to pay?The ransom demanded varies. Victims of a 2014 attack in the UK were charged £500. However, there’s no guarantee that paying will get your data back

Internet

INTERNET

• The Internet is a global network of interconnected network, enabling users to share information along multiple channels.
• A computer that connects to the Internet can access information from a vast array of available servers and other computers by moving information from them to the computer’s local memory.
• A majority of widely accessible information on the Internet consists of inter-linked hypertext documents and other resources of the World Wide Web (WWW).
• Computer users typically manage sent and received information with web browsers; other software for users’ interface with computer networks includes specialised programs for electronic mail, online chat, file transfer and file sharing.
• The movement of information in the Internet is achieved via a system of interconnected computer networks that share data by packet switching using the standardised Internet Protocol Suite (TCP/IP).
• It is a “network of networks” that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies.
• It is really a way for computers to communicate and share informations.
• It is a fast developing net and is of outmost importance for public sector undertakings, educational institutions, research organisations etc.

Services of Internet

E-mail

• The internet enables user to exchange data/information and communicate via electronic media.
• E-mail messages are usually encoded in American Standard Code for Information Interchange (ASCII) text.
• A popular protocol for sending e-mail is Simple Mail Transfer Protocol (SMTP) and for receiving it is POP3.

Chat

• It is the exchange of typed message by netizens.
• It enables netizens to ‘talk not vocal’ by typing and sending the messages back and forth.
• It has two modes—computer to telephone and computer to computer.
• Internet Relay Chart (IRC) developed by Jarkko Oikarinen in 1998.

Video Conferencing

• A service that allows a group of users to exchange video information over the internet.
• It include an audio teleconference facility.
• Each participant’s computer must have a camera, microphone and earphones (or speaker).
