What is a computer? How does it work?

A computer, in simple terms, is a machine that can be used to collect, store, analyze and present information, among many other functions. The information can be in the form of words, numbers, symbols, audio, video, images, etc. A computer has a number of key components, including input/output devices (such as keyboard, mouse, speakers, printer, etc.), display system (a monitor or a screen), processing device (central processing unit or CPU), storage device (hard-drive), etc. 


A computer runs by using an operating system, which allows us to input the information, analyze it, store and output it. Computers are used in all aspects of our lives and have made it easy, especially by taking control of a number of operations that are impossible for human beings. Imagine working with thousands and millions of data points and advanced modeling. 


Hope this helps.
