In today's technical era everyone wants to work virtually as corona pandemic showed us that there is no need to go office and most of the software tasks of different companies can be performed online effectively working from home and hence keeping ourself safe during this deadly situation. Definitely Computers proved God to us enabling all our daily tasks performed easily right from shopping for basic needs to online education of our little ones. So it's a great engineering example.
Computer : A perfect engineering example
In these hard days, in this deadly pandemic situation, we are facing number of challenges and fortunately by hook and crook everyone of us are trying to overcome them with an optimistic mindset.
Let's take an example of children education in such a situation. How it became possible for our buddies to study smoothly in such pandemic without going to school, it's because of online teaching with the help of desktops or laptops. So I think computers are the perfect engineering example which proved a bloom to human beings ,making human lifestyle more smooth as well as easygoing. Our little buddies are learning everything with the help of computer , right from yoga ,subjective plus objective topics ,coding, various artistic skills with lots of fun and actual involvement. We as a parent really feel great as our children are getting more and more talented.
Let’s take a brief look about its evolution:
Actually, computers are known and used today are relatively new. Although computers have technically in use since the abacus 5000 years ago, it is modern computers that had the greatest as well as most prominent impact on the society. The first full-sized digital computer was developed in 1944, named Mark I and was used only for calculations. It’s weight was five tons .
The first generation of computers occurred from 1940 to 1956 . These early machines required magnetic drums for storage of memory. The vacuum tubes here ,worked as switches and amplifiers. These computers produced so much heat that they regularly overheated irrespective of large cooling units.
Second generation computers(1956-1963) were also significantly swifter than their predecessor. These are the transistor computers which developed core memory which they used along with the magnetic storage.
From 1964 to 1971 third generation computers went through a significant change in terms of speed and courtesy of integrated circuits.There were large number of miniature transistors packed on the silicon chips.The modifications with the greatest impact occurred in the years from 1971 to 2010.
In these years 1971 to 2010, fourth generation technology developed to a point where manufacturers could place millions of transistors on just a single circuit chip which was called monolithic integrated circuit technology .Graphical user interface, or GUI, was also invented during this time. Computer memory and storage also went through continuous major improvements, advancements with an increase in storage capacity as well as speed.
Fifth generation computing has yet to be truly defined, announced as there are number of paths that the technology is moving toward the future of computer development. Now-a-days research is ongoing in the fields of artificial intelligence, nanotechnology as well as quantum computation.
Let’s take a look at Basic Computer Operations from an engineering standpoint:
1. Input: Information as well as programs are just entered into the computer through input devices that are the keyboard, disks, or through other computers via either network connections or modems that are connected to the Internet.
2. Output: Output Devices indicates the information on the screen (monitor) or the printer and sends information to other computers. They display messages about what kind of errors may have occurred and brings up dialog box asking for more information to be feeded as an input.
3. Processing: The CPU or central processing unit also known as the Control Unit , directs the operation of the input and output devices. The Coprocessor also called as the Arithmetic-Logic Unit does arithmetic calculations and comparisons. The RAM or memory temporarily stores information (files and programs) while you are using or working on them. The basic input/output system (BIOS)controls the dialogue between the various devices.
Learning the keyboard is the first step to learn the computers which automatically becomes easier through practice.
