Task 1. Read the text. Complete the task.
Computers can do many jobs. They can do math, store information
or play music. You can use a computer to write or to play games. What do
you know about the history of computers?
The first computers were very big. They were the size of a room!
People did not have them at home. Early computers could only do simple
math, like a calculator.
In 1958, Jack Kilby invented the microchip. Microchips are tine
but can store lots of information. They helped make computer smaller. In
1970s, computers were smaller and cheaper so people started to use them at
home.
In 1989, Tim Berners-Lee invented the World Wide Web to organise
information on the Internet. Now people all over the world use it.
Do you know that the first computer mouse was made of wood?

Explanation:
Step : 1 The original computers were enormous. They filled a room in size! People didn't have them at home since they were so large. Like a calculator, early computers could only perform simple mathematical operations.
Step : 2 In 1958 Jack Kilby invented the microchip. Microchips are tiny but can store lots of information. They helped make computers smaller. In the 1970's, computers were smaller and cheaper so people started to use them at home.
Step : 3 In the 1930's Alan Turing had the idea for a computer you could program to do different things. In 1958 Jack Kilby invented the microchip. Microchips are tiny but can store lots of information. They helped make computers smaller.
Step : 4 In 1969, the Honeywell Kitchen Computer was marketed as a luxury gift item, and would have inaugurated the era of home computing, but none were sold. Computers became affordable for the general public in the 1970s due to the mass production of the microprocessor starting in 1971.
Step : 5 Where the Web was born. Tim Berners-Lee, a British scientist, invented the World Wide Web (WWW) in 1989, while working at CERN. The Web was originally conceived and developed to meet the demand for automated information-sharing between scientists in universities and institutes around the world.
Step : 6 As part of an ARPA-funded experiment to find better ways for computer users to interact with computers, Douglas Engelbart of SRI—who would later work on the DARPA-sponsored ARPANET project, the Internet's precursor—invented the computer mouse. The first mouse was carved out of wood and had just one button.
