Latest Computer Science Courses List


The objective of this article is to gather and present in a consolidated form some of the important computer courses which are offered free of cost online by reputed organisations. This is primarily aimed at the career growth and personality development of the interested viewers.


Now- a- days, computer skills have become a vital and basic requirement of all jobs regardless of the position. As regards career, computers provide a visual base for learning. Computers play the role of recording, analyzing, gathering, processing and documenting a particular data which has made the human effort lesser, easier and quicker. Hence learning and keeping you updated with the latest computer knowledge and acquiring necessary skill has become extremely important. For a position starting from a retail cashier to the topmost person of an organisation, it be a corporate world or an educational institution, the very survival has become very much remote without the knowledge of computer. That is the reason why the current period is known as “the Era of Computer”. Under this context, there are two important factors which need to be considered in this regard. Number one placement: it is beyond the imagination of anyone to take it for granted whether an applicant without computer knowledge, apart from his having scope of becoming an asset or very much valuable to the organisation by virtue of his or her qualifications and other contributions or whatsoever at a later stage, will be able to get an entry or a placement into the organisation from the point of view of an employer and get better remuneration and number two the preparedness of the company: whether the companies are prepared, as an ongoing process, to make use of computer knowledge acquired by the recruitees by conducting periodical training programs for the development and benefit of employees and the organisation, as well.

Hence here the suggestion would be that if at all you haven’t thought of doing such courses till now, it’ s the time to make it happen, as today it has become a matter of survival of everyone which otherwise calls for getting equipped yourself with such basic requirement. Be sure of making yourself the best by learning suitable computer courses that are offered through free online courses.

Prerequisites: No computer experience is required other than the ability to use a web browser.

Course description: The objective of this course CS101 is to break the notion that computer is a complicated one and to clarify the myth about computer. It aims at those who do not have any prior computer experience. Participants will be taught about the essential ideas of Computer Science. It conveys the facts regarding computer that it works within a few simple patterns which are brought to life through this course, making it beneficial to users of computer. In CS101, the leaners play and experiment with short bits of “ computer code” in order to bring to life to the power and limitations of computers. Browser is the only thing required with which everything can be done and hence there is no need for extra software to download or install.

This course makes the learners understand in the real sense what a computer is, what a hardware is, what a software is and what an internet is. Moreover, CS101 will make the learners understand what code is and how it works. CS101 is a stepping stone for pursuing higher studies in programming.

Topics covered are:

  • How computer hardware works: chips, CPU, memory, disk
  • Necessary jargon: bits, bytes, megabytes, gigabytes
  • How software works: what is a program, what is “running”How digital images work
  • Computer code: loops and logic
  • Big ideas: abstraction, logic, bugs
  • How structured data works
  • How the internet works: IP address, routing, Ethernet, wi-fi
  • Computer security: viruses, trojans, and passwords
  • Analog vs digital
  • Digital media, images, sounds, video, compression etc.
