The Importance of digital technology

Email is basically for mail transmission electronically among people. There are also mailboxes, mail servers and other features like those in traditional post office systems. Only the difference is the simplicity and speed in the information transmission via computer and Internet.

E-mail is a great achievement in the world of communication. It is a great achievement because it allows messages reach its recipients within a very short time. If anybody asks how much time it would take for a letter to reach Bangladesh from EU or USA, even the top officials of the Post department would not be able to answer. The fastest mail delivery system of the world, DHL takes a minimum of three days to deliver mail to a client. There are of course other communication devices like phone, fax, telex, but often those are too costly. Among all the media of information transmission, email is the best as it is the cheapest and also the fastest. Also it ensures privacy or confidentiality, as the message is stored in the mailbox of the recipient directly. The sender can be sure that the recipient will obtain the message, which is sometimes impossible to assume in case of Fax. Another great benefit of email is that a user can access his/her messages from any computer of the world that has Internet access, whenever he/she wants to check for e-mail.

Every email recipient must have an email address to be identified and to temporarily store the message in the mail server. If there is no address, how you will be able to locate any person among millions of people. You must have an address, and so email is sent to addresses. Example: alam@bangla.net is an email address. Every address must be specified according to the mail server. The unique name before the @ sign would give the identification of the recipient. Here alam is the user or recipient and bangla.net is the mail server. Email works like a postal system. When someone mails a message (letter), first it is stored in a mail server. This is just like posting the letters in the local post office or letterbox.

There is versatile usage of the Internet. It is not only the source of huge information, but also a very powerful media to establish direct and easy communication among people and societies. There are the following special features:

·         The Information Superhighway

·         The World Wide Web

·         Bulletin Boards

·         Chat forums

·         E-mail

·         Information Retrieval etc.

The Internet is the super corridor or super highway where any sort of information can be published, retrieved or exchanged. Every Internet Server stores a large number of information on different topics. And there are millions of such servers, which are active all day long, even days or months together. There is no break, no pause. So information is available any time, any moment. You may just hook with Internet and get the piles of information.     The WWW is a very famous term, used to define the information population by any Internet server. It is basically a worldwide publication of the web pages to demonstrate peoples, societies and organizations. Every web page is technically a page of information, where different connecting heads/subheads are available to go through next pages of related information, which are bundled together. Bulletin Boards are actually simple forums where news, software, games, articles are bundled together with access to every member where they can directly contribute to or collect from the system, according to everybody’s requirement.

In a bulletin board, you may have the opportunity of conferencing with others, sending items without worrying whom you want to communicate with. Every member may have same freedom to collect anything at any time, according to his/her own convenience.
