Computer is one of the inventions of the 20th century that changed the

world greatly. The first computers of the 1940s were enormous. But now

they are almost in every family and in every office building.

Most rnachines do only one job, some are multifunctional ( e.g. а ТУ set +

  • DVD player). But no device is as multifunctional as computer. The parts

of the macblne (or its hardware) remain the same, you change only the

program (software) and your computer immediately learns to do various

things. А browser program is designed to look at pages on the Internet (you

can also say to browse, tbls accounts for the word browser). А word processor

program lets you to print text and then change styles of fonts and sizes of

162

pages. А database program is used for searching and sorting records. Such

program is used in shops, libraries, hospitals, accountant offices, and so on.

They make work with great amounts of data much quicker.

Computers are found everywhere and used in every sphere of life. In а

plant one can make а computer model of а car or plane and check its

resistance to stress. Such calculations without а computer could have

taken several months. Computer is used at school: children watch films,

presentations and web pages. This helps them to study effectively.

Computers also have some disadvantages. There is а famous joke that

computers are designed to solve problems but half of the time they are the

problem. As computer is а complicated device, one small breakage may

stop its work. Moreover, the equipment is soon out of date.

Besides, there is а problem of compatibility. First of all, there are

hardware devices which can't work with the old operating systems, such as

а processor, а hard disk drive, а video card, etc. Then, there are programs

which need more resources than computer actually lшs.

Thirdly, computers become more and more complicated, and much

effort is required to learn how to work with them. Fourthly, computer

viruses cause а lot of trouЬle - they can spoil, remove or steal computer

data, and every user knows it well from his experience.

And on top of all, computer is а multifunctional device, as we already

know, so it can bе used both to do work and to entertain oneself. Children

often fall prey to computer and Internet: they play computer games, spend

their free time chatting with friends on the Internet and doing practically

nothing. This aspect can't bе denied.

То crown it all, computer is а good device like many others, designed

to help people. But it's our own free will that lets us use it in order not to

waste time but to get best results.

  1. The computer was invented in the 20th century, with the first computers being developed in the 1940s.

  2. In the middle of the 20th century, there were not many computers as they were enormous in size. However, now they are almost in every family and office building, indicating a significant increase in their availability and use.

  3. Yes, a computer is a multifunctional device. While most machines only do one job, a computer can be programmed to perform various tasks by changing the software.

  1. The text does not provide a specific year when the computer was invented, but it mentions that the first computers appeared in the 1940s. This indicates that the computer was developed as an invention during the early part of the 20th century.

  2. In the middle of the 20th century, there were not many computers, primarily because the first computers from the 1940s were enormous and likely expensive and complex to operate. The text suggests that these early computers were quite large, which would have made them impractical for widespread use in every home or office at that time. It was only later that computers became more common in families and office buildings as they became smaller, more affordable, and more user-friendly.

  3. Yes, the computer is indeed a multifunctional device. The text highlights this by comparing computers to other machines that might only perform one function or a few functions. Computers, on the other hand, can perform a vast array of tasks depending on the software (program) installed. For example, with different software, a computer can browse the internet, process words, manage databases, and much more. This adaptability and capability to perform various tasks make the computer exceptionally multifunctional.
