How are you all? I
hope studied my previous post and enjoyed it.
Now in this post I am going to tell you about more interesting
thing. Before starting I would like to
give today’s question related to tech. The question is what is the full form of
GOOGLE??????
Today’s topics are as follows------
·
Why was the invention of printing press
important????
·
When were computer used first?????
·
What is space shuttle
1} Why was
the invention of printing press important???
The invention of printing press was
insane. It helped people to copy many pages at a time. With the help of this printing method a lot
of text was printed in a very short time…
People had access to book and they could read it and educate by themselves.
Opinion could be transmitted in books, newspaper, or handouts. This freedom of
thought was quite new at that time. Many
ruler feared it and ordered burning of books.

2} when were computers used first???
Computers play a very vital role in
our daily life. They do a lot of help in the people work. They reduce the
manual work of people… In this modern
world we should know who had invented the
computers??

The word computer came
from the phrase “to compute”. Another
meaning of computer is to calculate.
Tools that had been helped in the computations such as abacus are used
before 3000 years ago but the computers which do calculations very fast are
used since 70 years. Today the world can no longer be imagined without
computers. The world of bits and bytes are also opened for the blind. One has
to careful while downloading the information from the internet because malicious
virus can enter and attack the computer.
3} what is
space shuttle???
The space
shuttle was developed by the NASA is different form other
spaceships-------------- almost all its
parts can be recycled. When the shuttle is launched the two launching rocket
get separated at a height of about 50km and their landing impact in the sea is
reduced by parachute.
The rockets hull are caught by the retrieval ships of NASA and filled again for later launching. Only the huge external fuel tank vaporizes in space. When the shuttle has to return it switches off the drives before entering the earth’s atmosphere and then lands on the ground in a gliding flight.
