1 Introduction and Definition

A desktop computer and a laptop are both types of personal computers that are portable or simple to carry around and share many of the same components. Using the internet, creating documents, doing graphic design, storing files, and corresponding with others are all intended uses for laptops. The laptop can be either battery-powered or hooked into an outlet to work. It executes typed commands and is used to create documents and drawings, as well as to communicate with others. Additionally, some laptops are enclosed for high-performance gaming and include internal software storage. The monitor, keyboard, mouse, computer memory, hard drive, motherboard, and central processor unit are among the primary components of a laptop.

2 Overview

The display screen, small speakers, keyboard, data storage device, pointing devices (such as a touch pad or pointing stick), operating system, processor (central processing unit (CPU)), and memory are all combined into one system as a laptop in order to provide many of the input/output capabilities of a desktop computer. Most contemporary laptops have built-in webcams and microphones, and many also have touchscreens. Both an internal battery and an external power supply via an AC adapter can be used to power laptops.

There are major differences between different types, models, and price points in hardware parameters including processor speed and memory capacity. Depending on the intended function, design components, form factors, and construction might also differ dramatically between models. Rugged notebooks for use in construction or military applications are some of the models of a laptop. Originally thought of as a small niche market, portable computers gradually evolved into modern laptops, largely for specialized field applications, including in the military, for accountants, or for traveling salespeople. Portable computers became widely employed for a number of reasons as they developed into contemporary laptops.

3 Components of a Laptop

3.1 keyboard 

With letter and symbol keys, the key board is an input device similar to a typewriter that is used to input data. Additionally, the electrical impulses that are transmitted by these keys are registered by the keyboard’s circuitry.

3.2 Mouse 

The Mouse is a plastic tool used to point at things and track movements in two dimensions. The mouse uses mechanical sensors to translate a user’s hand motion into the computer.

3.3 Monitor

The monitor is an output device with a screen that looks like a television. It delivers instructions and displays instructions as text, pictures, or graphics.

3.4 Memory

Memory is used to store vast amounts of data as well as temporary or permanent files. It is housed inside silicone chips that are incorporated into the computer.

3.5 Hard Drive.

The portion of the computer’s disk drive known as the “hard disk” is where digitally encoded data is kept.

3.6 Motherboard.

The motherboard is the backbone of the computer, connecting all of its parts at once and enabling communication between them.

3.7 Central Processing Unit

An electrical circuit known as a central processing unit carries out the directives implied by computer program instructions.

3.8 Graphics Processing Unit (GPU)

A graphics processing unit (GPU) is a computer processor that quickly performs mathematical calculations to create visuals and images. Both business and consumer computers utilize GPUs. Traditionally, 2D and 3D pictures, animations, and video have been rendered using GPUs.

3.9 Explanation

A person using a laptop may complete a wide range of tasks because the device’s primary purpose is to respond to orders that enable it to create documents, obtain information, or communicate with other devices.  A laptop computer must be turned on before it can start processing data. This means that the power supply unit or a power adapter will supply the computer with power from the wall socket. The computer will do a Power Up Self-Test, or POST, as soon as it is powered on. POST is a diagnostic test that the computer runs to examine all of the fundamental hardware elements needed for it to function, including the power supply and the processor. Following POST, the laptop will connect to the computer’s software and check for the bare minimum operating system needs before loading them. The Graphical User Interface, or GUI, can now be viewed on the monitor once the operating system has loaded.

 The motherboard controls and connects the monitor and the computer’s primary parts. This comprises the video card, which projects the image onto the screen, as well as the keyboard and trackpad, which let one operate an operating system like Windows. The applications on the PC can now be used. The computer processor types command into the keyboard, which are subsequently carried out, and signals are sent to the computer monitor. Additionally, a mouse can be used to direct the laptop to perform specific actions. An individual can, for instance, open and close files or opt to design papers using a mouse. Because it can produce big tasks, the laptop is quite effective. This makes it a very useful tool for business owners, and demand for portable computers has increased in recent years due to the increased storage capacity of modern laptops and their ability to carry out many of the same functions as standard desktop computers.

5 Conclusion

                Since the beginning of human evolution, devices have been employed for calculating. An abacus was one of the earliest and most well-known tools. The first mechanical computer was then being developed by Charles Babbage, the inventor of computers, in 1822. Finally, he created an analytical engine, a general-purpose computer, in 1833. It had an ALU, some fundamentals of flowcharts, and the idea of integrated memory. As technology advanced throughout time, computers shrank in size and processed information more quickly. Adam Osborne and EPSON introduced the first laptop in 1981.

                Computers have gone through a lot of evolutionary stages from the ancient times through to the Roman Empire to the industrial age to the Sliderule to Blaise Pascal amongst others. Technological advancement has now made computers and laptops very affordable and available to everyone and also at a very moderate price due to competition in the market due to many companies manufacturing laptops in this 21^st Century age where the world is seen as a global village. Laptops makes tasks such as typing, printing, calculating, pricing, and many easier and faster. Emerging technologies such as Artificial Intelligence, Data Science, Internet of Things (IoTs), Coding amongst others through the use of modern laptops and other technological devices has changed the way things are done.

                Aside all the positive effects of laptops and computers, the big question now is that, is technology creating more jobs or destroying more jobs? Is it changing cultural values and attitudes? People can sit behind a laptop or smart phone without interacting with anyone which eventually affects social skills.
