Ethernet Hub

July 13, 2007

An Ethernet hub connects all the computers on a LAN (local area network). The Ethernet hub forwards packets of information on to all computers in the network. Unlike an Ethernet switch, it cannot identify the specific destination of a packet of data, so it can only forward it to the whole network. This can cause the network to go slow.

If two or more computers in the network try to transmit data at the ame time it will cause a collision  – all computers on the network then go through a specific process to resolve the collision, further slowing the network.

HTML – Hypertext Mark-Up Language

June 28, 2007

HTML, or Hypertext Mark-Up Language, is a common language used on the World Wide Web to format webpages and documents.

Code, or tags (such as <strong></strong>, which go at the beginning and end of text you want to make bold), are added to “mark up” the text so that when a user views the webpage on their internet browser, it is formatted correctly and appears as the writer or web editor wanted it to be displayed. (Although different browsers can display pages differently, using the most up to date code for html should minimise this problem.)

If you are setting up a website, you will find that most web editing packages allow you to type any content then format it using the types of buttons you’re familiar with from a Word package – B, and I, for Bold, and Italic, for example. So you don’t need to know html, although it does help to have an idea of how particular tags format a webpage.

Internet users with wireless-enabled laptops can access the internet via a hotspot when they are away from their own home or business wireless network.  Hotspots are sited in public areas such as coffee shops, hotels, airports, railway stations, and business areas such as Canary Wharf – anywhere where people on the move may want to go online.

Hotspots may be set up for public use, or they may simply be someone else’s wireless network that is not adequately secured. Access to the internet via a public hotspot may be free or charged-for.
