Microsoft Excel

In this week we learnt, in my opinion, more than basic knowledge about Microsoft Excel. the way of the lecture was the same as the last week's lecture. I mean interesting, because lecturer called some student to check their knowledge. And he called me too....I came up on the stage and did what he asked me to do.

I hope I did well)...As for me, I knew about Microsoft word and powerpoint, but my weakest is Excel. I did know a lot. But in the lecture, I have learnt a lot of thing such as calculate, summarize, sort and so on....Thanks the lecturer for that...

About Me

Hello everybody....

My name is Lazizhon and I'm from Uzbekistan. I'm 20 years old. I came here in february 2012...

Here I'll write my reflections in introduction to computer and internet ...

You can find more information about by just clicking my name at the bottom in the right corner =)

Binary decimal, octal etc. numbers

In the first lesson of the first week we did ice breaking session first...

Our lecturer introduced himself at first, then all students one by one introduced themselves.
After the ice -breaking session, the lecturer told us about what we are going to learn in this course, what assignment we should do and so on.
The first week's topics were quite easy for me and my friends, because we studied introduction to information technology. Theses subjects seemed to me almost similar....

The new thing we learnt was these kind of numbers called binary numbers. Besides we learn decimal, octal and so on.

History of computers

Pre computers and Early Computers (before 1940s)

In this week we started lecture by recapping what we learnt in the previous week. The lecturer gave us some exercise related to binary,decimal, octal and etc. number... We counted them, convert them from one to another and so on.
Then we started new topic. It was about computers, its history, architecture of them, size, processing power and their types.
We began to learn from computers' history first.:

First Generation (1940-1950) :: Vacuum Tube

Second Generation (1950-1964) :: Transistors

Third Generation (1964-1974) :: Integrated Circuits (IC)

Fourth Generation (1974-Present) :: VLSI / ULSI

Fifth Generation (now and the future)

Right after that, we studied computer's processing the way it works...

Then Times came to learn its categories. We learn that it has five categories, they are:

Embedded computers

Personal computers

Mobile devices/ computers
