CLOUD COMPUTING - USING SOFTWARE ON THE INTERNET
Cloud computing means using software that is installed on the Internet. You can also save your work on another computer instead ofthehard drive of your own PC or laptop. Music, letters, presentations and other projects can be stored on clouds, data storage areason giant servers on the Internet.
There are many so-called web applications that can do the same as normal desktop software. Google Documents, for example, gives you a text editor, a slide show applicationand a program forcreating tables and diagrams. You can use these programs for free – from any computer all over the world.
Up to now web browsers were only used to searchfor information on the Internet and show it. But now they have become something like operating systemswhich can give you almost everything that you have on your own PC desktop.
Cloud computing can also be cheaper than buying expensive software. Many basicapplications on the net are free, but you may have to pay to use some of the more complexprograms. Companies do not have to buy expensive software licensesfor all their workers and computers do not have to be better and more powerful all the time because all you need is a simple web browser, like the Internet Explorer and Firefox.
Cloud computing allows people from different parts of the world to work on a project together. Teachers and pupils, for example, might work on the same text together. Companies around the world can work together on a singlecomputer and do not have to send data back and forth.
There are, however, some things that make computer users skeptical. One of the big problems is security. With cloud computing, your data is givento someone else. Users are also worried that they might lose their data on other computers. In any case, cloud computing is marching forward and in a few years we may only be having a web browser running on our PCs.

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 )
