OPERATING SYSTEMS

 Operating system (OS) is the most essential software that runs in our computers. It is a collection of software that controls the computer hardware and provides services to the computer programs (also called as applications). OS is the first software that is installed into the computer and without it; the computer is of no use as it will not be able to communicate with the hardware. Once the OS has started up, it manages all of the software and hardware on the computer. Sometimes, there are many different programs running all at the same time, and they all need to access the computer’s central processing unit (CPU), memory, and storage. The OS manages all of this to make sure each program gets what it needs and do not interfere with each other. It performs various operations like taking input from keyboard, displaying output on the screen, working of monitor, mouse, scanner, printer and other external (hardware) devices. OS is also responsible for security of the computers, ensuring that unauthorized users do not access the computer data. Some of the most common OS are Microsoft Windows, Linux and Apple Mac OS. Most operating systems use Graphical User Interface (GUI) which allows the user to click on icons on the screen and give commands to the computer. All OS may not have the same GUI, like Windows 7 has a different GUI than Apple Mac OS. 

Nowadays, OS is present in mobile phones, video games etc. The different types of mobile OS are Symbian, Android and Apple iOS.

INTRODUCING INFORMATION TECHNOLOGY ENGINEERING

Engineering is one of the most desired professional courses in India. Every branch in engineering relates with certain technological field. 

Information Technology (IT) is a branch of engineering which concentrates on both software and hardware sectors. 

IT students are exposed to programming, databases, networking, and system administration and also learn to utilize telecommunications. IT usually provides skills and knowledge which covers more of practical aspects. Often students are confused between Computer Science (CS) and IT. IT is more about applications of computing whereas CS is all about the science behind these applications, programming and requires a certain proficiency in mathematics. If we compare the curriculum for both the branches in the top engineering colleges, it can be safely said there doesn't seem to be much difference between them. Information Technology is a vastly undermined course and often given lesser importance than the coveted CS course. But nothing more could be farther than the truth. IT isn't a diluted version of CS. Both the courses have their own requirements and one’s interest is all that matters.

Technology sector is a field which is quite lucrative in the job arena and is expected to be so for the next decade and more. The computer industry has been growing with leaps and bounds. Many Indian companies require talented IT engineers every year. So deserving job-aspirants shouldn’t find any difficulty in finding their dream job as well as their dream pay-package. Well, of course it also depends on your grades and the reputation of the college you are graduating from. Post-graduation in IT is also offered in India and abroad and further opens up a wide array of opportunities.
