00:55Nowadays, not too much of the studies regarding in deep for this post and for such type of topics.
01:05That's why I have decided to just make a very very important step by step informative video
01:15for the kids, those who are watching, for the people, those who want to know about computers.
01:22Now, what is a computer and how this electronic device works?

01:59So, make it very very clear that please follow my Facebook page, Instagram page and thread pages.
02:08Let's begin.
02:09Now, the first question which arrives in the minds of several people who want to purchase one PC, laptop or
02:19any operating system they want.
02:21What is a computer?
02:24What is the basic definition of this machine?
02:29A computer is an electronic device that processes raw data into meaningful information by following instructions.
02:42Instructions of what type?
02:44Operating through a cycle of input, processing, storage and output devices.
02:51It uses hardware, things like physical parts like CPU and RAM.
03:01Now, let me know what is CPU?
03:07Central processing unit means the whole system is processed by a particular unit that is called CPU, central processing unit.
03:18Another thing is RAM, very very important part, random access memory.
03:25So, the very very important basics of central processing units means CPU and RAM that is random access memory.
03:36A software program to perform arithmetic and logical operations.
03:46Typically, typically using a binary system of zeros and ones.
03:54So, this is the very very simple meaning what is all about computer.
04:02Now, the key components and their rules.
04:06Central processing unit means CPU is regarded and treated as the brain of any operating system like computer, PC, laptop,
04:17whatever name you give.
04:18But the system is the same is regarded as the brain of any computer that executes instructions and processes the
04:30data.
04:31Second thing which works very very important in this machine is all about a very very important to notice that
04:42is memory means RAM, random access memory.
04:46Temporarily, temporarily stores data to quick access by the CPU central processing unit.
04:55Stored in the form of HDD and SSD.
05:01Permanently stores files, applications and the operating system files.
05:07Input devices, input devices, input devices, input devices, what are input devices which is used by the human in Raj,
05:15particularly in the form of any object like keyboard, mic or sensors that fed data into the computer.
05:27By the way of keyboard, mouse, mic, mic or sensors, you fed the data inside into your computer.
05:36What are output devices related to this?
05:39Output devices is used widely around the globe.
05:44Monitors, monitors, monitors, printers or speakers and nowadays many other things like earphones, mouse, different types of mouse which are
05:55wired, non-wired.
05:57These are all comes under output devices category that display results.
06:05Another thing, how a computer works.
06:11The input process, the input process, output cycle.
06:15Input, the user provides data, example typing on a keyboard and writing something in English.
06:23Like he is writing Raman, it will be seen on the screen of the monitor.
06:29Processing, what type of processing?
06:32The central processing unit fetches instructions from software and manipulates the data.
06:38Data is the function of central processing unit.
06:42Storage, data is stored in RAM means random access memory while active or in storage devices for long-term use.
06:56Fourth one is output.
06:57The computer displays or act on the result.
07:02Example, showing text or a screen or a image or a video or a deal.
07:07Nowadays, many things it shows on the screen of the PC.
07:12Computer ranges from tiny embedded clips in household appliances to massive supercomputers.
07:22Supercomputers but all functions by following these basic principles all over the world.
07:29So these are some many very important facts related what this computer is all about.
07:37There are a board range of industrial and consumer product uses these computers as control systems including simple special purpose
07:51devices like microwave, ovens and remote controls.
07:56Remote controls are used on LCD monitors in the forms of television and also on PC and factory devices like
08:06industrial robots.
08:08Computers are at the core of general purpose.
08:14Devices such as personal computers and mobile devices too.
08:18Devices such a smartphone also computer powered the internet which links billions of computer users and laptop users around the
08:31globe.
08:33Early, computers were meant to be used only for calculation purpose.
08:39Simple manual instrument like the abacus have added people in doing calculations in ancient terms and times.
08:55Early in the industrial revolution, some mechanical devices were built to automate long periods tasks such as guiding patterns.
09:09For looms for looms, more sophisticated industrial or you can say electrical machines did specialized analog calculations in the earliest
09:2420th century.
09:27The first digital electronic calculating machine were developing during World War II.
09:33Both electromechanical and using thermonic valves, the first semiconductor transistors in the late 1940s were followed by the silicon-based
09:51MOSFET means MOS transistors and
10:00monolithic integrated circuit chip technologies in the late 1950s leading to the microprocessor and the microcomputer revolution in the year
10:141970s.
10:16The speed, power and the speed, power and the versatility of computers have been increasing dramatically ever since then the
10:26transistor counts increasing at a rapid pace.
10:30More is lost notes that counts doubled every two years leading to the digital revolution during the late 20s and
10:42early 21st centuries.
10:44So these are the basic things which I have told you inside this video and in the next video I
10:53will going to discuss about the various parts of computers.
10:56But in the meantime I will also like to discuss some more about the computers, systems and various types of
11:06things used along with.
11:08But before that it is very very important to know the history of computer itself.
11:14Once again I will going to tell you more about a computer is a mechanic that can store and process
11:23information, most computers really on a binary system which uses two variables 0 and 1 to complete tasks such as
11:35storing data, calculating algorithm and displaying information.
11:41computers.
11:42Computers come in many different shapes and size from smartphone to supercomputers waiting more than 300 tons.
11:53Now the question arrives here is very very clear, who invented the computer?
11:58many people throughout history are created with developing early prototypes that leads in the modern computers.
12:13During World War II.
12:16During World War II, physicist John Mochielli, engineer 1, Ms. Perce, Scott and Junior and their colleagues at the University
12:31of Pennsylvania designed the first programmable general to pose electronic digital computer,
12:41the electronic numerical integrator and computer means E-N-I-A-C.
12:48Now another question arrived related to this topic is very very important that what is the most powerful computer in
12:56the world?
12:56As of 2025, the most powerful computer in the world is the American supercomputer means E-I-Captain.
13:09Located at the Lawrence Livermore National Laboratory in California.
13:15The computer is used for national security purposes and to ensure that the country's nuclear stock bills is secure.
13:27How to programming language works?
13:30It is very very very very clear, popular modern programming languages such as Javascript and Python work through multiple forms
13:42of programming,
13:43paradigms and functional programming.
13:47Two, which uses mathematical functions to give output based on data input,
13:54is one of the more common ways code is used to provide instruction for a computer.
14:02So these are some basic basic questions which I have covered in this video.
14:07And what is finally I want to tell you about what is analog computers?
14:14That is very very important to understand.
14:16Analog computers use continuous physical magnitudes to represent quantitative information.
14:25At first they represented quantity with mechanical components such as differential analyzer and integrator.
14:36But after World War II, voltage were used by the 1960s digital computers had largely replaced them all.
14:48Non-thickness analog computers and some hybrid digital analog systems continued in use through the 1960s
15:01In tasks such as aircraft and space flight simulation.
15:06One advantage of analog computer and communication is that it may be relatively simple to design and build an analog
15:16computer to solve a single problem.
15:20Another advantage is that analog computers can frequently represent and solve a problem in real time.
15:29That is the computation and proceed at the same rate as the system being modulated by it.
15:38Their main disadvantages are that analog representations are limited in precision.
15:46Typically a few decimal places but fewer in complex mechanisms and general purpose devices are expensive and not easily programmed.
15:59So thank you for watching. I have given the most important information in this video.
16:05In the next video I will give the more information.
16:07But before leaving, hit the subscribe bell and like so that you never lose the upcoming video on this channel.
