World Computer Literacy Day, observed on 02 December, aims to encourage everyone to make full use of information and communication technology. It also wants to promote Digital Literacy among people, especially among children and youths.
Computers are now an essential element of human life due to the digital revolution in today’s modern era. They can perform massive calculations in just a fraction of a second and bring information from around the world in the blink of an eye.
Evidently, we can see computers in all parts of life, from education to shopping, banking to entertainment, medical to daily routines, etc.
Historically speaking, Computer Literacy Day was first organized by the famous Indian cooperation NIIT on its 20th anniversary to raise computer literacy awareness.
It has been a long journey from the first typewriter to the most recent computer technology. From the typewriter, computers evolved into desktop PC, laptops, smartphones, and tablets. The computer is the centre of the office where almost all the work is done.
Computer Literacy Day is sometimes also called Digital Literacy Day.
Digital Literacy is a set of skills that enables individuals to create, use, evaluate, modify, and share digital information, products, and services. It involves using new information technologies to achieve or maintain professional and personal goals.
Additionally, the internet has revolutionized life in many ways. It has reduced the time needed to get information. It has made education available at anytime and anywhere. It has provided a means for people to communicate with other countries easily.
However, it has also increased the amount of misinformation and hoaxes used to spread malicious content.
Computer literacy has many benefits:
- It helps you to stay updated about the latest trends.
- It improves problem-solving and critical thinking abilities.
- It also helps in the improvement of your career opportunities.
- Improves our skills in using social media, the internet, and other electronic devices.
- Besides that, it also reduces stress by doing hours of work in minutes if used correctly.
We now live in a world where technology has completely seized control of our lives. We depend on it to connect, find answers to our questions, make our businesses run smoothly, and much more.
If you can understand computer language and skills like programming, you can fully benefit from technology. According to one report in 2021, more than 60% of the world’s population is connected to the internet.
With such rapid growth, making everyone a computer-literate person is crucial. In short, we cannot survive without computers.
Here are some interesting facts regarding computers;
There are more than 700 programming languages.
The first computer game was created back in 1961. The name of the game was ‘Space War’. Steve Russel along with his team spend around 200 hours making the first version of the game. The game didn’t earn any money.
The first computer virus was created in 1982 by a 15-year-old kid.
The first programming language was FORTRAN (Short for FORmula TRANslation). It is a general-purpose programming language especially suited to numeric and scientific computations.
A computer understands everything in the form of 0’s and 1’s. For example, the word ‘hello’ is understood by a computer something like 0110100001100101011011000110110001101111. It is known as the binary language, and it is a one of the types of programming languages that the computer can understand directly (without the need of any language processor).
In the future, learning how to code would be as common as basic literacy! If you learn to code, it will improve your analytical thinking ability, problem-solving skills, and ability to make quick decisions.
The first computer did not use electricity!
If you learn one programming language, it would be much easier to learn the other ones on your own.

The language Python was not named after the snake ‘Python’.
Over 70% of the programming jobs are not in the fields of technology. Rather they are in the fields like medical, banks, finance, etc.
A programmer is always a coder, but a coder may not be a programmer!
PHP was not meant to be a programming language. Its founder, Rasmus Lerdorf created it just to manage his web pages!
People who create malware to commit cybercrimes are known as Black Hat Hackers while those who write programs to protect against malware are known as ‘White Hat Hackers’.
A computer bug is a part of the code that makes the program wrong. However, the first computer bug was an actual bug! In 1947, Admiral Grace Hopper of the US Navy observed that something was hindering the computer’s operation. He found a moth stuck in the relay of his computer!
There is an esoteric programming language (essentially a compiler language) called ‘INTERCAL’ which has predefined keywords like PLEASE, FORGET, IGNORE etc. If the programmer doesn’t use, PLEASE enough times while coding, the compiler would reject the code!

The first woman to earn a PhD in computer science in the U.S. goes by the name of Mary Kenneth Keller. Before receiving her PhD, she had a good background in physics and mathematics. Mary Kenneth Keller has been a motivation for many women who want to pursue a career in computer science because she achieved a lot during her time.
The Sasser worm, which hackers have used to cause atrocities to businesses and other computer users, mainly targets computers that run on Microsoft operating systems by exploiting a vulnerable network port. Once the worm completes infecting the system, it deletes itself to make it difficult for anyone to trace it.
Microsoft, H.P., and Apple started building their computers from a garage before they were able to advance. H.P. preserved their garage to tell a story of the humble beginning of now what many people consider as one of the top computer brands in the world. Further, they made their garage a private museum that does not allow tours.
In the year 2010, a high school in Pennsylvania used computers to spy on their students while they were at home.

John McAfee admitted during an interview in 2012 that he does not use the antivirus that he developed, the McAfee Antivirus program. He seemingly agreed that the antivirus was too annoying. Nonetheless, millions of people are still using antivirus to curb virus attacks.
In 1969, it was tough to send the word “LOGIN” over the internet. It was so complicated that when a University Professor in Los Angeles tried to send it to another professor in the University of San Francisco, the internet collapsed. The first message sent over the Internet was: “lo.” The programmers were able to transmit the entire “login” message about an hour later.
The original name of the window operating system was interface manager. However, in 1982, experts saw it fit to change the name after various crucial considerations.

The classification of computers is based on internal structures, features, applicability, and computer system. There are eight types of computers: mainframe computer, supercomputer, workstation computer, personal computer, Apple Macintosh, Laptop computer, Tablet and Smartphones.
Super Computers are the fastest and the most expensive types of computers. A supercomputer can solve complex calculations within the shortest time possible.
