Computing – History, Process, Principles, and Many More

In its broadest definition, a computer is any apparatus that automatically takes information as input and returns an output.

However, each time a computer acts, such as starting a program, modifying a picture, or playing music, it is computing architecture.

To compute, in the broadest meaning, is to do mathematical calculations. This technology cannot function appropriately unless its various components can talk to one another and work together in harmony.

What is Computing System?

“Computing” refers to any purposeful endeavor that uses or is aided by electronic computers.

This field of technology contains the output of hardware and software development with the analysis and testing with algorithmic techniques.

Science, technology, engineering, mathematics, and even the social sciences all are combined elements in the field of computer technology.

Moreover, cybersecurity, information technology, digital art, information systems, engineering, data science, and software engineering are all integral elements of the computing architecture industry.

Computers and calculators are all examples of computer technology.

In the past, it was used to describe the work of mechanical devices and, even earlier, the result of human computers.

Methods designed for use with pen and paper (or chalk and slate), with or without tables, are also part of computing architecture’s long and illustrious history, predating computer hardware development.

The earliest known method of arithmetic is the Babylonian abacus, created between 2700 and 2300 B.C. It is still a calculator, but Abaci looks different.

In his 1931 work “The Use of Thyratrons for High-Speed Automatic Counting of Physical Phenomena,” C. E. Wynn-Williams made the first known suggestion for using digital electronics in computer technology.

Claude Shannon proposed the idea of using electronics for Boolean algebraic operations in his 1938 work. Field-effect transistors have been around since 1925.

Julius Edgar Lilienfeld first presented the idea. In 1947, under William Shockley’s supervision at Bell Labs, John Bardeen, and Walter Brattain constructed the first functional transistor, a point-contact device.

In 1953, the University of Manchester developed the Manchester Baby, recognized as the world’s first transistor computer.

However, early junction transistors were cumbersome devices that proved challenging to mass-produce, limiting their usefulness to a select few niches.

Mohammed Atalla and Dawon Kahng of Bell Labs developed the metal-oxide-silicon field-effect transistor (MOSFET or MOS transistor) in 1959.

The MOSFET enabled the development of high-density integrated circuits, which sparked the computer revolution and the subsequent microcomputer revolution.

Work Stages of Computing Process

A computer moves through these steps by ‘running’ an algorithm. Moreover, a computer requires detailed programs or instructions to do a task established on data.

The all-around process work of a computer consists of three steps: data entrance, processing, and finally output.

Yet, to complete their tasks, computers must also deal with various data and information. The central processing unit (CPU) manages all its operations as its brain.

Let us explore the computer life cycle and learn more about each step-

During this processing phase, information required by the program is input into the computer. The use of input devices achieves this.

Both the mouse and the keyboard have become standard input devices.


A program specifies how the input should be processed.

The system follows these instructions during the processing phase by utilizing the newly entered data.

Output refers to the results of the computer’s processing at this point.


The processing results are presented to the user as information.

This is accomplished using several output devices.

The screen (also known as a monitor or visual display unit [VDU]) and the printer are the two most popular forms of output equipment.

Data & Information

Information is any numbers, letters, or other symbols converted into a machine-readable format. Without context or interpretation, data is meaningless.

Data lacks context until it is processed by a computer, which becomes information.

There are a plethora of data formats. A computer ultimately stores information as a string of numbers.

Any user can enter any sort of data into the computer through a mixture of techniques.

Numbers, dates, pictures, words, and sounds are the most typical formats of data that a computer can take in and interpret.

CPU (Central Processing Unit)

A computer’s central processing unit (CPU) is the machine’s brain; other components like input and output devices and storage are necessary for the computer to function.

Processing units perform tasks such as data searching and sorting, calculation, and decision-making.

The Central Processing Unit (CPU) comprises the Main Memory, Control Unit, and Arithmetic and Logic Unit (ALU).

Reasons for Learning Computing Technology

Learning computers encompasses a broad set of aims that help individuals acquire foundational expertise in information technology. Some of the aims are-

Figure 3 – Five Reasons for Learning Computer Technology

Master the Art of Problem Solving

Use your reasoning, computation, and imagination to find answers. Identify and analyze the issue, create an algorithm to process the data systematically to provide the desired output, and then implement the method as a computer program.

Gaining Knowledge of Computer Programming

With the use of a computer, users can understand the ropes and be a specialist in the most standard programming elements.

They can even utilize different software tools to effectively create, fix bugs and test a program.

Understanding Building Blocks

Learn the concepts behind computer technology and how they work, including discrete and formal mathematics, models of computation, and algorithm complexity analysis.

Develop Mind in the Liberal Arts

In this way, you can think critically about computer science. You may enhance your pupils’ ability to express themselves vocally and in writing.

Or even you can increase your understanding of the ethical and societal effects of software and technology.

Moreover, improve your capacity for ongoing education, both in computers and beyond.

Acquire A Well-rounded Understanding

Students pursuing a degree in science should broaden their knowledge across several subfields.

Interdisciplinary computer network majors should be prepared to study their chosen field’s basics.

Besides that, they need to develop creative approaches to solving challenges in their chosen areas of study using a wide range of computer technologies.

Major Principles of Computing Network

Most scientists up until the 1990s would have defined computing architecture as the study of algorithms, data structures, numerical techniques, programming languages, operating systems, networks, databases, graphics, AI, and software engineering.

However, there are only really seven different types of computing architecture concepts.

Each heading offers a new way of looking at computers, a different aperture to see the landscape. Let us learn the basics of each idea –

We categorize issues based on the amount of computing architecture required to solve them.


Entropy is the informational unit of measure. File compression, cyclic redundancy checks, and secure encryption


Methods that prevent or remedy situations where the outcome is uncertain


While all storage systems are hierarchical, they can only provide the same amount of access time to some items. Regardless of the period, all calculations favor subsets of their data items.


Exhaustive searches describe most heuristic algorithms. Information flows may express many mental activities quantitatively.


It is possible to approximate most computer systems’ throughput and reaction time by modeling them as networks of servers for which fast solutions exist.


Understanding complex systems helps to break them down into smaller, more manageable pieces.

Modules may be categorized according to the durations of the events that cause object changes.

Different Sectors of Computing Technology

Computing architecture can be divided into various sections based on individual needs and other activities. So let’s get to know about other different sectors of this technology below-

Cloud Computing

In cloud architecture, users access and utilize servers and software from a remote location without requiring the involvement of the resource’s original provider.

The category of a cloud service counts on the segments it presents.

This can be categorized as Software as a Service (SaaS), IaaS (Infrastructure as a Service), or Platform as a Service (PaaS).

This facilitates the realization of economies of scale by single consumers or modest enterprises.

The discipline is intriguing partly because of its potential to promote energy efficiency.

However, there are several concerns with this centralized style, particularly concerning privacy and security.

Legislation, as it now, does not provide enough protection for users against corporations abusing data on corporate systems. This indicates the need for more legislation regulating cloud computing networks and IT firms.

Quantum Computing

Computer science, information theory, and quantum physics intersect in studying quantum.

Despite the novelty of including information in physics, there is a close relationship between information theory and quantum mechanics.

Quantum employs qubits rather than the binary system of ones and zeros used in classical computers.

Qubits can simultaneously be in a superposition or the one and zero states.

This means that the qubit value is not always between 1 and 0 but might fluctuate at different times.

Quantum entanglement describes this characteristic of qubits and is the core notion behind the quantum computing network, which enables quantum computers to do massive calculations.

When classical computers lack the processing ability to perform a particular computation, such as in molecular modeling, scientists often turn to quantum computers.

Traditional computers need the capacity to calculate large molecules and their reactions. Still, quantum computers may one day give a tool.

Edge Computing

The concept of “edge” refers to a kind of distributed system that places the processing and storage of data nearer to its origins.

As a result, we anticipate faster reaction times and reduced bandwidth use.

In the late 1990s, content-dispersed networks were developed to provide web and video content from edge servers near consumers. This was the genesis of the edge system.

The earliest commercial edge services housed applications including dealer locators, shopping carts, real-time data aggregators, and ad insertion engines on the networks’ edge servers in the early 2000s.

The Internet of Things (IoT) is an everyday use of edge architecture. There is a widespread misunderstanding that “edge” and “Internet of Things” are interchangeable.

Fog Computing

Data, processing, storage, and applications in fog computer networks are distributed nodes between the data source and the cloud.

Fog computing design brings intelligence and processing closer to data generation. Thus, the terms are occasionally interchangeable.

Efficiency gains are the most common motivation, while security and regulation compliance are valid factors.

 The meteorological word for a cloud near the ground inspired the fog metaphor because, like fog, most network congestion occurs at the network’s periphery.

It is widely thought that Ginny Nichols, a product line manager at Cisco, was the first to use the word. Cisco Fog Computing architecture is a trademark.

Final Thoughts

Computing networks have significantly evolved, affecting people’s everyday lives, occupations, and social connections.

From mainframes to PCs, cellphones, and cloud storage, the computer tech sector has pervaded contemporary life.

Due to the demand for faster processing, more storage, and better user experiences, hardware and software development has progressed.

Since computers can now manage human workloads and decisions, AI and ML have opened up new avenues of investigation.

Future computer systems will let us explore unexplored places and tackle difficult jobs.

As these technologies become increasingly interconnected, we must consider ethical considerations, privacy, and security risks.

By utilizing computers responsibly and ethically, we can shape a future where technology promotes humanity and enhances life for everyone.

What is the simple definition of computing?

The Latin word for “compute” means “to prune.” ‘Computing’ is used to describe the use of electrical computers for any practical purpose. The fact that computers can perform calculations far more quickly than humans led to their naming.

What is an example of computing?

The use of computing devices such as desktops, laptops, tablets, smartphones, the internet, cloud computing, email, text messages, and social media is now commonplace.
