Computer virus is a program which is designed to copy itself into other programs, with the intention of causing mischief or damage. A virus will usually execute when it is loaded into a computer's memory.

A properly engineered virus can have a devastating effect, disrupting productivity and doing billions of dollars in damages. For example, experts estimate that the Mydoom worm infected approximately a quarter-million computers in a single day in January 2004. Back in March 1999, the Melissa virus forced Microsoft and some other very large companies to completely turn off their e-mail systems until the virus could be contained. The ILOVEYOU virus in 2000 had a similarly devastating effect. In January 2007, a worm called Storm appeared - by October, experts believed up to 50 million computers were infected.

The most common forms of electronic infection are:

  • Viruses: A virus is a small piece of software that piggybacks on real programs. For example, a virus might attach itself to a program such as a spreadsheet program. Each time the spreadsheet program runs, the virus runs, too, and it has the chance to reproduce (by attaching to other programs) or wreak havoc.
  • E-mail viruses: An e-mail virus travels as an attachment to e-mail messages, and usually replicates itself by automatically mailing itself to dozens of people in the victim's e-mail address book.
  • Trojan horses: A Trojan horseis a computer program which claims to do one thing (it may claim to be a game) but instead does damage when you run it (it may erase your hard disk).
  • Worms: A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well.

Wireless networks have limited range. Network range depends on the type of 802.11 protocol, the strength of the device transmitter and the architecture of the surrounding area. Some structures such as walls and metal frames reduce the range of a WLAN by 25%. However, users can extend the range of a WLAN. Repeaters forward the wireless signal to access points or routers and increase the range of a network.



Bandwith and latency are the measures of computer network speed, or data transfer rate. Bandwidth is the maximum throughput of date in bits per second. Some modems support 100 Gbit/s but speed depends on the hardware and software used. Latency is the delay that network creates during the transfer of data. Users have no or very little control over bandwidth and latency.


1 Wireless networks don’t have a wide range. ( T / F )

2 Network range depends on different factors. ( T / F )

3 Walls and metal frames can increase the range of a WLAN. ( T / F )

4 It’s possible to increase the range of a WLAN. ( T / F )

5 Data transfer rate is measured in bandwidth and latency. ( T / F )

6 The minimum throughput of data in bits per second is the latency. ( T / F )

7 Speed depends only on the hardware used. ( T / F )

8 Users can control the latency. ( T / F )
