Algorithms : The building blocks of the Computer Software In the previous blog about algorithms, It described the great ideas of computer science but computer scientists describe this ideas, call them "Algorithms". So what's the difference between idea and an algorithms? The simplest answer to this question is to say that an algorithm is a precise recipe that specifies exact sequences of steps required to solve a problem. The great example for supporting this answer is how children's get taught to add two large numbers in school as shown below. 345611 + 989811 = xxxxx2 -> xxxx22 -> The above addition shows first two steps involved in adding two large numbers. So we can see that the process of addition contains precise number of steps that is also universal irrespective of input. The key feature of an algorithm is that no human intuition or guesswork required. Its just like a mechanical machine. Therefore each of the mechanical steps can be programmed into the co...

 Let us understand how the Computer Science ideas grew over the timeline. In 1930's, a British genius founds the field of computer science then goes on to prove that certain problems cannot be solved by any computer to be built in future, no matter how fast, powerful or cleverly designed. In 1948, A Scientist working at a telephone company published a paper that founds the field of Information theory. His work will allow computers to transmit message with perfect accuracy even when most of the data is lost due to interference. In 1956, A group of people attends a conference at Dartmouth with goal of Founding the field of Artificial Intelligence.  In 1969, A Researcher at IBM discovers elegant way to structure information in a database. This technique is now used to store and retrieve the information present in online transactions. In 1974, researchers in British governments lab founds the secret way for communicating securely between two computers without any other computers k...
