What is a Computer?

A computer is an electronic machine that processes all the information which provided to it and produces the desired output. Like any other system, computer system also needs an input which is then processed to get the output required. It has internal and stored programs for the same.

Types of Computer –

1) Micro Computer

2) Mini Computer

3) Mainframe Computer

4) Super Computer

1) Micro Computers – The First micro computers were made with 8 bit microprocessor chips and were designed to be used by only one person at one point of time.

2) Mini Computers – The First Mini Computer was made by DEC ( Digital Equipment Corporation), which also happened to be the largest manufactures of the minis and launched the super mini in October 1977.

3) Main Frame Computers – Libraries of Application programs developed in mainframe computers are quite greater than those of the micro and mini computers.

4) Super Computers – India recently has made up a super computer and termed it PARAM 10000.

History of Computers: -

In 1822, Charles Babbage, a mathematics professor at Cambridge University, made up a machine which termed “difference engine” and was often used for simple computations related mostly for logarithmic and trigonometric tables.

Next Generations: -

ENIAC – Electronic Numerical Integrator and Calculator was made up in 1946 and was the first ever electronic calculator. Per second, the ENIAC did about 5000 additions, for which it took up 150 KW power and had to be always cooled by water.

EDVAC – Between 1947 and 1950 the More School personnel and the Ballistics Research Lab of the U.S. Army made up a computer which was called EDVAC – Electronic Discrete Variable Automatic Computer which was based on ideas of John Von Neumann and also this was the first ever effort to bring to computers the concept of stored programs.

Does India need communal parties?

I think, it was Tan's post on this blog itself, Republic Day Event, where this question was raised. My answer. YES. we need communal parties even in Independent, Secular India. Now let me take you, back to events before 1947. When India was a colony of the British Empire. The congress party, in its attempt to gain momentum for the independence movement, heavily used Hinduism, an example of which is the famous Ganesh Utsav held in Mumbai every year. Who complains? No one. But at that time, due to various policies of the congress, Muslims started feeling alienated. Jinnah, in these times, got stubborn over the need of Pakistan and he did find a lot of supporters. Congress, up till late 1940's never got bothered by it. And why should we? Who complains? No one. But there were repercussions. The way people were butchered and slaughtered during that brief time when India got partitioned, was even worse than a civil war scenario. All in the name of religion. And there indeed was cr...

Politics - A Profession

This post is loosely inspired by the  TATA Tea a d  where this politician goes to ask for votes and a voter asks him for his qualification and work experience the the important 'job' that he is embarking upon. The politician laughs at the voter, asking him what job is the voter referring to. The voter responds, "The job to run the country". Do politicians in other countries view politics as a profession? Or is politics viewed similarly across international boundaries? The best way of course to find out is go to that ever useful tool for professionals - LinkedIn.  Here are the results: Barrack Obama Hillary Clinton Sarah Palin The apparently technologically challenged Senator   John McCain. I also came across many politicians, prime ministers who have LinkedIn profiles. While having a LinkedIn profile is not a certificate of a person character, one has to appreciate the intent. Reach out to masses, and more importantly, take politics as a profession. Successful leader...

Cutting people off isn’t strength—It is a trauma response

Your ability to cut people off and self-isolate is not a skill you should be proud of—It is a trauma response Cutting people off and self-isolating may feel like a protective shield, but it is often rooted in unresolved or unhealed trauma and an inability to depend on others. While these behaviors seem like self-preservation, they end up reinforcing isolation and blocking meaningful connections. Confronting these patterns, seeking therapy, and nurturing supportive relationships can help break this unhealthy cycle. Plus, a simple act like planting a jasmine plant can symbolise the start of your journey towards emotional healing. Why do we cut people off and isolate? If you’re someone who prides themselves on “cutting people off” or keeping a tight circle, you might believe it’s a skill—a way to protect yourself from betrayal, hurt, or unnecessary drama. I get it. I’ve been there, too. But here’s the thing: this ability to isolate yourself is not as empowering as it may seem. In fact, i...
