6.2 Reading
Suggested answers Original text
A network can be defined as the connection of two or more computer systems which allows them to exchange data. Networks, especially the internet, are a very important part of daily life. They work by transferring data between different devices or nodes and allow many types of communication such as email, instant messaging or chat.
The simplest example of a network is two or more computers linked directly to each other, which is known as a peer-to-peer network. In a peer-to-peer network, all participants have equal status, which means sharing resources equally. In client-server networks, one computer – usually more powerful – provides data to client machines on the network. It can also provide shared access to peripherals.
Networks can be LANs (Local Area Networks), where computers are relatively close to each other, or WANs (Wide Area Networks) where computers are located further apart.
WANs are connected together in national or regional networks and these networks link together to form the wider internet.

Review the key paraphrasing skills with the whole class before starting this exercise. This can be done by elicitation of earlier work, or by using Vocabulary Bank 6.1.
VOCABULARY BANK 6.1 Paraphrasing
Depending on the class, there are a number of possibilities for this activity. One approach is to divide the text into sections and allocate a section to each student, or to pairs of students. Alternatively, all students can work on the same paragraph in pairs, or individually.
Use the students’ work to feed back visually, highlighting their use of different paraphrasing techniques (possibly using different colours for each).
Student B paraphrase
Networks enable computer systems to share data by linking them together. They make it possible to use email and other types of communication and to share peripherals.
Some changes made
1. short summary omitting many details, such as examples
2. synonyms: exchange data g share data
Networks can be peer-to-peer or client-server. In peer-to-peer networks, all computers are equal, but in client- server networks, the server computer is more powerful than the other client computers.
1. omitting much of the detail in the original sentences
2. changing language: all participants have equal status, which means sharing resources
equally.gall computers are equal
In Local Area Networks (LANs), the parts are nearer together and in Wide Area Networks (WANs), they are further away.
The internet links many WANs together.

Closure 6.2_Closure
Divide the class into two teams. Write the five topic sentences from the reading text on pieces of paper, or use the cut-outs as provided in the PDF. One team chooses a topic sentence and reads it aloud. The other team must give the information related to the topic sentence. Encourage students to get as close as possible to the actual paragraph content in the text.
