Happy Valentine's Day :)

In this great day, all of you should pause for a moment and be grateful to the one who made Valentine's day possible.

No, no and NOO. I am not talking about some Saint Valentine of Rome who was imprisoned and executed for performing weddings for soldiers who were forbidden to marry. He obviously is important to valentine's day, but the real credit to make this day possible goes to (as you might have already guessed) Eukaryotes.

For those who don't know, Eukaryotes were the first complex life form to appear on our tiny blue planet nearly 2 billion years ago. But they didn't stop there, unlike their distant ancestors 'Prokaryotes' which originated 3.6 billion years ago and were simple cell forms of life and primarily spend all their lives in water doing photosynthesis and asexual reproduction and created enough oxygen to make origin of Eukaryotes possible.

By this time, you would have already guessed, Yes !! Eukaryotes were the first to start heterosexual reproduction which ultimately lead to celebration of Valentine's day after roughly 1.2 billion years after a long chain of evolution and mass destruction that wiped off several species and allowed Homo sapiens to develop into (what some  believe) socially aware intelligent life form.

Also, it is very important to note that since we all evolved from same Eukaryotes, there is a good probability that that little bacteria on the pizza which you ate last week was your distant cousin. Same is true for the chicken you will eat tonight and the mosquito which you killed yesterday while it was sucking your blood. So I will end this long message on this happy note and once again Happy Valentine's day to all.

List of free online journals publication in Computer Science and Information Technology

Usually scholars find it difficult to hunt for some good online  journals to publish their research work. You must take impact factor of journal into consideration before making decision of choosing some particular journal. There days lot of research papers are coming from engineering young minds. Undergraduate students usually look for free online journals for publishing their work. In this post I am providing list of  free online journals publication in Computer Science and Information Technology :

Journals publication in Computer Science and Information Technology










Please don't forget to note Impact factor of these journal.

What is Impact factor ?


The impact factor, often abbreviated IF, is a measure reflecting the average number of citations to recent articles published in science and social science journals.

The Von Neumann Architecture | Computer architecture and organisation | CAO

All computers more or less based on the same basic design, the Von Neumann Architecture!

Model for designing and building computers, based on the following three characteristics:
1)The computer consists of four main sub-systems:
Memory
ALU (Arithmetic/Logic Unit)
Control Unit
Input/Output System (I/O)
2)Program is stored in memory during execution.
3)Program instructions are executed sequentially.
