COMPUTER HARDWARE

A computer needs both hardware and software to run, but decisions about the hardware must be made before you buy a computer. Understanding some basic information about the hardware is very important and will help you decide on the most suitable computer for you.

• Processors: The processor controls all of the activities of a computer. Processor speed is often shown in gigahertz (GHz). High processor speed means that your computer can run faster.

• Random Access Memory, or RAM: It is displayed in gigabytes (GB). The RAM shows how powerful your computer is. The more RAM in a computer, the more tasks your computer can do at the same time.

• Storage space: It shows how much information (such as documents, music, photos, etc.) a computer can store. It is also displayed in gigabytes (GB). There is other information about the hardware, such as the screen size, the battery, and the weight, that you need to know before choosing the best computer for you.

1. processor

a. shown

2. RAM

b. to keep something and use it later

3. displayed

c. the part of the computer that controls all other parts

4. storage space

d. a type of computer memory

5. store

e. the amount of information a computer can keep

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

Computers are now an important part of human life. Without them, the modern world will stop: nobody will be able to travel, work, shop, watch TV, get money, or send messages.

However, together with computers come viruses - a kind of computer program. They move from one computer to another and damage the memory or other parts of the computer. Some viruses are difficult to stop; they can damage millions of computers in a very short time. The first virus called Brain appeared in 1986. In 1987, a more dangerous virus called Jerusalem appeared. It stayed in the computer and did nothing until the date was Friday 13th when it started to damage the computer's memory.

By the late 1990s, most computers were part of the e-mail and Internet systems. This meant virus programs could do a lot of destruction very quickly. The Melissa virus, for example, could move from one computer to another by e-mail - it automatically sent itself to every other email address in the address book.

In an effort to fight against viruses, programmers wrote antivirus software. Virus programmers are getting better all the time, but so is the antivirus software. However, a virus is always spread before a remedy takes action. People believe that one day a computer virus will bring the whole world to a stop for a few hours, which may paralyze many nations' government systems and cost the lives of many people who are traveling in a plane or undergoing an important operation.

42. The first virus appeared _________.

A.In 1986 B. In 1987 C. In 1990 D. On Friday 13th

43. Computer viruses became extremely dangerous _________.

A.on Friday 13th

B. when the first virus called Brain was created

C. when computers were connected to e-mail and Internet systems

D. in 1987

44. Which statement is TRUE about computer viruses?

A.The Melissa virus is part of the Internet system.

B. The virus Jerusalem is harmless because it did nothing.

C. A computer virus can kill people.

D. computer virus is a program.

45. A “remedy" (paragraph 4) refers to __________.

A.viruses B. programmers C. medicine D. antivirus software

46. The word "which" in the last paragraph refers to __________.

A.a computer virus created by people B. a computer virus

C. a few hours' stoppage caused by people D. the stoppage of the whole world caused by a computer virus

London's cycle hire scheme

A. London is a 'world city': one of the most important economic and financial hubs in the world. It has a population of around eight million people and contains hundreds of iconic buildings which are recognized over the world. London receives around 20 million visitors each year, a large proportion from overseas, who mingle with further millions of people who travel into the city from a wide area to work in the central area. It is frequently rated as providing the most satisfying 'cultural experience' for visitors to any city.

B. One of the challenges involved in managing (and living in) such a huge city is the abity to mo ve people efficiently around it, for the purposes of work and leisure, and at reasonable cost. The London blackberry cab is one responese to this problem. The much quoted result of million of daily vehicle fondements is a very low average speed for traffic on London's roads and frequent suggestion problems.

C. Many cities have taken steps to reduce the amount of traffic on the roads by adopting a range of measures which can broadly be described as either 'carrots' or 'sticks': those which eigher promote, or discourage certain activity. London has already been forced into trying a number of measures to reduce traffic congestion. There have included:

.Traffic management systems which included the world's first traffic light. It was installed outside the Houses of Parliament in 1868 to reduce congestion in this area.

.An underground system which was the first in the world. The first section opened in 1863, and the network is still developing. Since 2003, it has been managed by Transport for London. The classic London Tube map forms part of city's cultural heritage, and has been much copied and adapted elsewhere.

• The Cross Rail development: http://www.crossrail.co.uk due to provide high frequency
rail services through two new tunnels under Central London from 2017.

• The congestion charging system – introduced in 2003, and extended in 2007 - charges many motorists (there are some exemptions) £10 to enter the central charging zone between 7am-6pm Monday to Friday.

• The Oyster card – an automated charging system which speeds up the use of public transport using a specially chipped card, which can be pre-charged with ‘credit’.

D. The latest solution is the Barclays London Cycle Hire Scheme. In 2010, London joined a growing list of cities that had turned to the bicycle for a possible solution to traffi c congestion. Cities like Amsterdam have long since been associated with bicycles. Other cities that already have cycle hire schemes include Paris, Copenhagen and Barcelona. In Paris, the system is known as the Velib scheme, a word which merges the word for bicycle with
freedom. It is funded by advertising. The London scheme was launched on the 30th July 2010 with an initial total of 5,000 bikes spread around 315 locations, with plans for further extensions. The bikes are fairly robust so that they can withstand the knocks of daily use. The are fitted with dyamo-powered LED lights, have three gears, achain guard and a bell. Each bike is also fitted with a Radio frequency Identification (RFID) chip, so that its location can be tracked. The bkes have puncture-proof tyres and are regularly checked over the mechanical faults.

E. It is hoped that people will experience London in a more direct way. Instead of descending into the earth, they will cycle the streets and thus gain “a different view” of London and improve their own mental maps of the city. They will also be getting exercise, which in an age of soaring obesity rates can only be a good thing, can’t it?
