The Internet

• By definition "The Internet is a network of computers which are linked all over the world- the International Computer Network. This allows millionns of users to communicate with each other and access a vast source of shared information" (Source: ww.which.net).
  
  
• It is also referred to as "the utlimate network" (Cox, G), comprising millions of interconnected computers world-wide (thus the term "inter...net"). Essentially, it is an information sharing system, "enabling users to access data stored on varoius computers located anywhere thousands of miles away- on land, at sea and in the air (interesting eh?).
  
  
• However, the working of the Internet is a complex matter, which is beyond the scope of this awareness discussion. If you need to know more, please contact us or go to data communications webpage.

Origin of Internet technology

• According to Cox, G (Softenica Ltd), "In the mid-1960s the U.S. Department of Defense (DoD) sponsored the design and implementation of a research network, called ARPANET which connected universities and government establishments. Eventually, in the mid-1980s, it led to the development of what we now know as the Internet which comprises thousands of interconnected networks and millions of machines (called hosts).......".

The World Wide Web (www.)- the Internet (websites)

• This is the most popular way of accessing information through the Internet, which contains many websites (webpages) interconnected by hyperlinks. Clicking a link takes you to another website, webpage or web resource in general.
  
  
• The "world wide web", is often referred to as the "world's ultimate electronic library" with " contributions from millions of people (websites) interconnected by links.
  
  
• For example, click this external link www.slcb.biz to access the Sierra Leone Commercial Bank's website ("biz" stands for business). They provide Internet banking as well.
• Click www.google.com to go to the world's most visited search engine website (for Internet research).
  
  
• You are currently on our website "www.eases.co.uk". This means, you are accessing information from our organisation called "eases" and it is a "company in uk" (.co.uk) through the Internet (www). Thus, the website address (or domain name) is "www.eases.co.uk".
  
  
• The general format to download or access a website on the Internet is http://www."name-of-organisation"."x" , "x" can be:
• ".co.uk",".com" (i.e. commercial company), ".org" (non-profit organisation like charities), ".ac" (academic institution), ".net" (networking company) etc. "x" simply describes the website (i.e. the type of organiastion).
  
  
• Thus, to download (access or visit) our website on the Internet, you need to type in "http://www.eases.co.uk". "http://" stands for "hyper text transfer protocol", a data-communication term for downloading files(information).
• The opposite term is" ftp>" (file transfer protocol) for uploading (sending) files (data or information).
  
  
• If you desire to know more about this subject, please do not hesitate to contact us. Formal training on Internet technology is available as well.

Internet Service Provider (ISP)

• This is a company or organisation that allows you access to the Internet, usually by selling its services to you (the user). For example Yahoo, Hotmail, MSN (Microsoft Network) etc, providing users with Internet access (free or for fee), through e-mail (electronic mail) addresses, usernames and passwords.

Web/ Internet Browser

• Computer program (software) that "understands and reads" the languange of the "World Wide Web" (HTML, see below). To use (browse) the Internet, you need to install a web browser (e.g. Microsoft Internet Explorer, Netscape Navigator, etc).
  
  
• The web browser settings on your computer determine the way text, images, colours etc are displayed on the computer screen. The details of this subject are also beyond the scope of this exercise, which is to provide basic but professional information, about the Internet, to those who need it.

HTML (Hypertext Markup Languange)

• This is the language of the Internet. It is what the web browser interpretes and displays on your computer screen in the form of ordinary readable human language- e.g. English, Arabic or Chinese text., when you access the Internet.
  
  
• HTML is a computer programming language that determines the formatting information (e.g. paragraph styles, image layout and size, colour and size of text, web page layout and background colour, creating hyperlinks, etc.).
  
  
• It is a computer program; and one needs to learn it, in order to understand it and possibly become a programmer (like I did, to become a web designer). There are various courses available for this, but you do not need to learn HTML to use the Internet. For more details, hit about proprietor.
