Everything about computers

Hi,

I am quite excited to start the technical part of my blog! I hope so are you!

Let's start with the Abc of computers that we all find a bit hard to put in to words. These are my own definitions made really simple and easy to understand!

Computer:  An electronic device that computes, stores, processes , manipulates and displays the data. Coined from the term "compute", means to calculate.

Facts:  First ever computer was used for mathematical calculations.
Founder: Charles Babbage - The Father of computers - invented the first ever mechanical computer called "Babbage's Analytical Engine"!

Features of a Computer / Advantages of computer over a calculator: Speed, Accuracy, Storage, Multi tasking, Diligence (and many more).

A computer comprises of Software and Hardware (all the physical - internal or external components/peripherals that are connected to or a part of computer ex. Keyboard, Mouse, Cabinet, Joystick, USB - pen drive etc. that we can touch and feel)

Software: Set of Applications/Programs.

Program: Set of instructions

Instruction: Statements that tell the computer (dumb one!) what to do and how to do!

Set of Instructions can be either in the form of:

  • Program - Set of instructions (can be directly input to the computer)
  • Algorithm - Set of instructions in pseudo code (for high level design & understanding of coder)
  • Flow Chart - Set of instructions in pictorial form (For easy overview)

To be continued....

    Diligence refers to the ability to work continuously without getting tired! Which the humans can't do.

Look before you Leap...

Hey there, Lets talk about Information. Many a times we are not the first hand recipients of information. We receive information from someone or through the Internet or the media. Some of us are wise enough to ponder over the details received from any third or fourth party sources but most of us blindly believe in what comes around from Mr.XYZ and everyone around. A wise one would use his/her intellect and wisdom to ponder over that information and decide whether to trust and take it in or throw it out. That is what makes us different from animals. The power of thinking and intellect. To illustrate this, lets remind ourselves of this famous story of a fox. There was once a fox in a jungle. One day the fox accidentally slipped in to a deep well and was unable to get out of there. So it came up with an idea. As soon as it heard a sheep bleat, it started exclaiming very loud  "wow. This water is so tasty!".  Hearing this the sheep went close to the well and asked...
