Give the characteristics communicating over the Network
More and more, it is networks that connect us. People communicate online from everywhere.Communication begins with a message, or information, that must be sent from one individual or device to another. People exchange ideas using many different communication methods.All of these methods have three elements in common. The first of these elements is the message source, or sender. Message sources are people, or electronic devices, that need to send a message to other individuals or devices. The second element of communication is the receiver, of the message. A third element, called a channel, consists of the media that provides the pathway over which the message can travel from source to destination. Consider, for example, the desire to communicate using words, pictures, and sounds.
For it we can add the email. Email – electronic mail is method of exchanging digital messages between computer users. It may consist of text, files, images and etc. The first email was sent by Ray Tomlinson in 1971. To send and receive email message, you can use an email program. An e-mail system is the equipment and software that carries and manipulates e-mail messages. It includes computers and software called e-mail servers that sort, store, and route mail.
Any person with an e-mail account can send and receive e-mail. An e -mail account provides access to a storage area, or mailbox, supplied by an e-mail provider. Each mailbox has a unique address, which typically consists of a user ID, an @ symbol, and the name of the computer that maintains the mailbox
How create an HTML Web pages?
HTML was invented in 1990 by a scientist called Tim Berners-Lee. The purpose was to make it easier for scientists at different universities to gain access to each other's research documents. By inventing HTML he laid the foundation for the web as we know it today. HTML (Hypertext Markup Language) is a set of specifications for creating documents that a browser can display as a Web page. HTML consists of a series of short codes typed into a text-file by the site author — these are the tags.
A web page constructed using HTML has a basic and essential structure. The page always begins with the start tag of the html element and always terminates with the end tag of the html element as follows:<html>
...web page... </html>
The head section begins with the <head> start tag and terminates with the </head> end tag. Immediately following this comes the <body> start tag and just before the html end tag comes the </body> end tag.
