Block Diagram of Computer

The basic structure of all types of computers is of the same type. But the internal design of the computer is of different types and sizes. There are five basic main components of a computer. Which is mentioned in the Block diagram of computer system, we will know about the components of computer system in further detail.

Later the instruction is processed with the help of CPU, and the computer system produces an output mainly with the help of output devices. A large amount of data is stored in the computer memory temporarily and permanently with the help of primary and secondary storage devices. This is called a storage device

Components of Computer System


Basically a computer system is made up of three major parts which are as follows –

Input Unit / Input Devices

Central Processing Unit

Output Unit / Output Devices
Input Unit / Input Devices –

As the name suggests, input devices are all those devices or hardware with the help of which data (words, pictures, voice etc.) and instructions are entered in the computer.

Or rather, with the help of these devices, the computer receives data and instructions. Such as – keyboard, mouse, scanner, light pen, touch-screen etc.
Functions of Input Devices –

Following are the functions of input devices –

It receives user data and instructions.
It converts these data and instructions into a language understandable by the computer, that is, it converts the data and instructions given by the user into machine language or binary language, so that the computer can easily understand the data and instructions.

NOTE – Here the words data and instruction have come up again and again, I am sure that you must have known about d

ata (raw data - unordered data). But what are these instructions?

Here instructions mean - the command given by the user to the computer, what to do with these data.

We will understand this with an example –

If we want to add four digits, then we enter four digits with the help of the keyboard (input device), but until we give the command to the computer, it will not add those digits. So what we order to add is called giving instructions to them.
Another example- If we have to sort the data (arranging the data in a sequence), then what we command the computer to do the sorting, this is called giving instructions.
Central Processing Unit (CPU – Central Processing Unit) –

The full name of CPU is Central Processing Unit.

It is also known as processor.

The CPU is the brain (brain/brain) of the computer system.

It is an electronic microchip that, based on the instructions given to the data, converts it into useful information after processing, and controls all the functions of the computer system.

Components of CPU

CPU has three parts –

Memory Unit or Storage Unit
Control Unit
Arithmetic Logic Unit (ALU- Arithmetic Logic Unit)

Memory Unit or Storage Unit –

Memory or storage unit is used to store data and instructions as well as intermediate results and final information/results.
Control Unit (CU – Control Unit)

The control unit is an important part of the computer's CPU (Central Processing Unit), which coordinates the activities of all other computer components. And directs and controls the operation of the processor.

Control unit controls the work of all peripheral devices connected to the computer such as Monitor, Printer, Scanner, Mouse, Magnetic disk (Hard disk) etc. and coordinates between all the devices and tells them what to do and When to do
Arithmetic Logic Unit (ALU- Arithmetic Logic Unit)

ALU, the critical part or component of the CPU where the actual execution of instructions during processing takes place. It is used to perform arithmetic and logical calculations.
Arithmetic operation or arithmetic operation

Arithmetic operations include addition (+), subtraction (-), multiplication (×), division (÷). All these calculations are performed by the Arithmetic section of the ALU.
Logical operations or logical operations

Logical operations are performed under logical operations. Under logical operation, comparative calculations are done. All these calculations are performed by the logic section of the ALU.

Cloud Computing Vs Grid Computing

The similarity between cloud computing and grid computing is uncanny. The underlying concepts that make these two inherently different are actually so similar to one and another, which is responsible for creating a lot of confusion. Both cloud and grid computing aims to provide a similar kind of services to a large user base by sharing assets among an enormous pool of clients.

Both of these technologies are obviously network-based and are capable enough to sport multitasking. The availability of multitasking allows the users of either of the two services to use multiple applications at the same time. You are also not limited to the kind of applications that you can use. You are free to choose any number of applications that can accomplish any tasks that you want. Learn more about cloud computing applications.

History of Computing PtI

We learn and know (hopefully) a basic history of the world, particularly major events like the French revolution, the American Civil War, World War I, World War II (wow lots of wars), the Spaceage etc. It is important to understand the concepts of these and many other historical events. Being able to recall the start year or the exact details of how such events unfolded is one thing, but on a human level, it is more important to understand the rationale, lessons and philosophy of major events. Ultimately history teaches us what makes us innately human. Furthermore, understanding history helps us realise the how and why we operate in todayHistory provides the context for today. It makes today seem ‘obvious,’ ‘justifable’ and ‘logical’ given the previous events that unfolded.

So, following this thread of logic, understanding the history of computers should help us understand how we have got to today. A today when computers moderate much of our communication with one another. A today where computers and screens are stared at for many (and often a majority) of our waking hours (especially during Covid). A today where the thought of working, socialising or learning without a computer would be an affront and a disadvantage. Just as major events like World War II and the Cold War have greatly contributed to today’s political and social climate. I would argue computers influence just as much (if not more) of our daily lives.

Therefore it is important for us to understand the evolution of computers to understand where we may be heading in our relationship with computers.

I would like to preface that the following articles outlining the history of computers by saying this is in no way an exhaustive history of the origin of computers. Some major events have been glossed over while other meaningful contributions omitted entirely.

Whilst the thought of history for some may make the eyes automatically glisten over, I will try and make the following series as painless and exciting as possible. While I paint a story of linear progress of computation, this is hindsight bias in action. We like to create a story of history attributing certain importance to some events and not others when in reality as these events were unfolding (and continue to unfold) it was not always obvious what was a gigantic discovery. It is only now with some distance that we can appreciate past event. This means perhaps in ten years this recount will emphasis other features and neglect some of the stories today we find so foundational to computer’s creation.

With all this in mind let’s begin !!

The first computers

Since their inception computers have taken over human work by performing tedious, complex and repetitive tasks. Interestingly, t_he__ word computer initially described humans_!! Initially computers were humans (often women) who were able to perform complex mathematical computations — usually with pen and paper. Often teams would work on the same calculation independently to confirm the end results. It is interesting to note that initally when electronic computers were developed they were referred to as such — electronic computers. With time as electronic computers became more and more pervasive and powerful, it became the human computer that was deemed obsolete and inefficient. The electronic was dropped and now when we discuss computers we think of nothing else besides our gracefull and versalite electronic tools. It is important to keep computer’s mathematical origin in mind as we will see it only further emphasises the never imagined pervasiveness and uses of computers today.

Our story begins with the humble abacus, generally considered the first computer. When researching I was puzzled how an abacus could be considered a computer. Luckily my curiosity was settled by a quick Google search (thank you Google). Google was even able to suggest my search before I completed typing ‘Why is the abacus considered the first computer’! I ended up on trusty Quora where one users: Chrissie Nysen put things simply-“Because it is used to compute things.” Though estimates vary, the abacus is thought to originate in Babylon approximately 5000 years ago. The role of the abacus was to ease in simple mathematical calculations- addition, subtraction, division and multiplication. In this sense, we can consider the abacus as a simple calculator. As farming, produce and populations increased in size, the abacus allowed the educated to more easily manage logistics. After the abacus the first computer, computer’s evolution remained dormant for some time……
