Computer hardware and software require each other, and neither of them can be realistically used on their own. Computers are used in various fields, such as homes, businesses, government offices, research organizations, educational institutions, medicine, entertainment, etc. because of their features and powerful functions. They have taken sectors and companies to a whole new level. Computers are best suited for the collection, analysis, categorization, and storage of data in science, research and engineering. They also help scientists to exchange data both internally and internationally with each other. Computers in the government sector are used to perform various functions and improve their services. In most cases, data processing tasks, the maintenance of citizens' databases, and the promotion of a paperless environment are the primary purposes of using computers.
In addition to this, computers play a key role in the country's defence system. Health and Medicine-. They are used to preserve information, records, live patient monitoring, X-rays, and more from patients. Computers assist in setting up laboratory tools, monitoring heart rate and blood pressure, etc. Besides, computers allow physicians to easily exchange patient data with other medical specialists. They help people get different educational materials such as images, videos, e-books, etc. in one place. Also, computers are best suited for online classes, online tutoring, online exams, and task and project creation.
Also, they can be used to maintain and track student performance and other data. Most countries use online banking systems so that customers can access their data directly. People can verify the balance of their account, transfer cash, and pay online bills, including credit cards. Besides, banks use computers to execute transactions and store client information, transaction records, etc. A computer's a programmable device that accepts raw data input and processes it as output with a group of instructions a program to supply the result. It renders output after performing mathematical and logical operations and can save the output for future use. The word "computer" derives from the word "computare" in Latin, which means calculating.
Computers are of different types based on different criteria. Based on their size, computers are of five types:. Micro Computers-. It is a single-user computer that has less capacity for speed and storage than the other types. The fact is that the present looks like it does because of the time and resources computers have saved us and this is an undisputed fact. Computers are becoming more complex and at the same time simpler to use making them widely distributed with a tendency to take over the world. There are many plans for the future of computers and as time goes by, they are capable of finding solutions to complex and unimagined problems.
They are used in almost all the industries from mining to hospitality management and everywhere they find a unique task, or several, that they can perform. They have become so indispensable to our lives that some people are actually considering making them a part of their body and integrating the computer operations with the organism. This can sound a bit bizarre but people are actually making advancements in this field and cyborg devices are being implemented to help people with disabilities more often as time passes. The potential the computer has to help us is immense and the limit is only our imagination and the resources we have at our disposal. This tool can be thought to perform endless tasks even the experts get surprised sometimes. The future looks like its full of stars but we have to keep in mind that through their use we speed up all our processes altering our existence in a sense we have to keep both eyes open for signs of potentially dangerous outcomes of some of the technological advancements we use.
A computer, in terms of definition, is such a device, which through the use of computer programming, executes the arithmetic and logical operations. Computers are used as control frameworks for a wide assortment of modern and shopper gadgets. This includes simple gadgets like microwaves and remote controls, plant gadgets, for example, modern robots and computer helped structure, and furthermore broadly useful gadgets like computers and cell phones. Charles Babbage, an English mechanical designer and polymath, began the idea of a programmable computer.
Considered as the father of the computer, he conceptualized and concocted the primary mechanical computer in the mid-nineteenth century. In the wake of chipping away at his progressive distinction motor, intended to help in navigational figuring, in he understood that a considerably more broad structure, an Analytical Engine, was conceivable. The contribution of projects and information was to be given to the machine by means of punched cards, a strategy being utilized as an opportunity to coordinate mechanical weavers as the Jacquard linger. For yield, the machine would have a printer, a bend plotter and a ringer.
The machine would similarly be able to punch numbers onto cards to be examined in later. The Engine consolidated a number juggling rationale unit, control stream as contingent stretching and circles, and incorporated memory, making it the primary plan for a broadly useful computer that could be portrayed in present-day terms as Turing-finish. The essential parts of a computer are the computer case, monitor, keyboard, mouse, and power cord. Each part assumes an important role in the functioning of a computer. The computer case is the metal and plastic box that contains the principal parts of the computer including the motherboard, the CPU and power supply. The monitor works with a video card, situated inside the computer case, to show pictures and content on the screen. The keyboard is one of the primary approaches to speak with a keyboard.
There is a wide range of sorts of keyboards, yet most are fundamentally the same and enables you to achieve a similar essential feature. The mouse is another imperative device for speaking with computers. Ordinarily known as a pointing gadget, it gives you a chance to point to objects on the screen, tap on them, and move them. Computers have no doubt made human life quicker as a result of extraordinary speed, accuracy and capacity, with which human can spare anything and pursuit it out effectively when required.
We can state that computer is an adaptable machine since it is entirely adaptable in carrying out different occupations. The ability to do many tasks together, or in computer terms what is referred to as multitasking is one of the real advantages of a computer. An individual can carry out different undertakings, numerous tasks, and figure numerical issues within a couple of moments. Computers can perform trillion of directions for every second. Other than this, one of the fundamental points of interest of a computer is its staggering pace, which causes human to finish their assignment in a couple of moments or even seconds.
Each one of the activities can be performed in a quick manner in view of its speed otherwise it requires a long investment to complete the assignment. Moreover, the storage capacity of computers is another of its abilities which make computers so powerful. You can store gigantic information inside a small hard disk. Concentrated database of putting away data is the significantly preferred standpoint that can lessen cost as well. One of the other advantages of computers is the precision of its calculations which are very hard to achieve manually. With the advent of technology, the computers have seen the darker side as well. Of late, there have been many instances of misuse of computers as well.
For instance, viruses and hacking are two tools which are used to attack computers and misuse them. The virus is a worm and hacking is basically an unapproved access over a computer for some illegal reason. Viruses are exchanged from email connection, seeing a tainted site ad, through removable gadget like USB and so forth. Once malware is moved in host computer it can destroy the record, overwrite the document, and misuse them and so on. For example, a huge bit of web was affected including Twitter, Netflix, and CNN in October on the grounds that the biggest DDoS assault was propelled on specialist organization DYN utilizing IoT Botnet. Such instances have given rise to cybercrimes. Cybercrimes imply computer system may have been utilized with the end goal to carry out unlawful activities.
Cyber stalking and Identity burglary are the focuses which go under online digital crimes. For example, one may get the access of your bank account or your shopping account like Amazon account and the hacker can have the capacity to access the bank account details or the credit or debit cards which can then be misused by the hacker. Moreover, with the increasing use of computers, there has been a decrease in the requirement of manual force as a lot of work has been taken over by computers. This was initially a cause of the increase in the rate of unemployment as well.
There is no doubt that our lives have been made much easier with the introduction of computers. How easy it uses an ATM machine to withdraw money. In fact, online examinations which have removed the bias the students had to go through at the hands of teachers have been possible only with the use of computers. There are so many benefits of computers that is simply not possible to term them as a curse to our society. However, everything must be sued judiciously, or else it does not take time for a boon to end up being a curse. For instance, we must make our kids understand the ill effects of using computers and cell phones for hours and encourage them to better reading and playing habits for them to go through their development process properly. Similarly, we must be aware of the cybercrimes one is prone to and follow the advice of the government from time to time in order to keep ourselves safe and secure from the ill effects of computers.

The term computer was once used to refer to a person who did computation, unlike today. The development of early prototypes that led to the modern computer is credited to many individuals throughout history. A series of breakthroughs, beginning with transistor computers and then integrated circuit computers, resulted in the development of transistor technology and the integrated circuit chip, causing digital computers to largely replace analogue computers. In this essay, we will discuss the various components and types of computers and talk about their uses in various fields. A computer is an electronic tool that manipulates data or information.
It can store, retrieve, and process information. We can type documents, send emails, play games, and browse the Web using a computer. It can also be used to edit spreadsheets, presentations, and even videos, or create them. Early computers were conceived only as devices for calculating. Simple manual devices such as the abacus have helped individuals do calculations since ancient times. Some mechanical devices were built early in the Industrial Revolution to automate long, tedious tasks, such as guiding patterns for looms. In the early 20th century, more sophisticated electrical machines performed specialized analogue calculations.
All those parts of a computer that are tangible physical objects are covered under the term hardware. The hardware includes circuits, computer chips, graphics cards, sound cards, memory RAM , motherboards, displays, power supplies, cables, keyboards, printers and "mice" input devices. There are five main hardware components:. Input Devices:. Example- keyboard, mouse, scanner, document reader, barcode reader, optical character reader, magnetic reader etc. Output Devices:. Example- monitor, printer, speaker, projector etc. Control Unit:. The control unit handles the various components of the computer; it reads and interprets decodes the instructions for the program, transforming them into control signals that activate other computer parts.
Arithmetic Logic Unit:. It is capable of performing arithmetical and logical functions. The set of arithmetic operations supported by a specific ALU may be restricted to addition and subtraction or may include functions of multiplication, division, trigonometries such as sine, cosine, etc. Central Processing Unit:. The ALU, control unit and registers and together called the CPU. It is sometimes called the computer's brain, and its job is to perform commands. We send instructions to the CPU whenever we press a key, click the mouse, or start an application. Software refers to computer parts, such as programs, data, protocols, etc.
In contrast to the physical hardware from which the system is built, the software is that portion of a computer system consisting of encoded information or computer instructions. It is sometimes called "firmware" when the software is stored in hardware that can not be easily modified, such as with a BIOS ROM on an IBM PC compatible computer. Computer hardware and software require each other, and neither of them can be realistically used on their own. Computers are used in various fields, such as homes, businesses, government offices, research organizations, educational institutions, medicine, entertainment, etc. because of their features and powerful functions.
They have taken sectors and companies to a whole new level. Computers are best suited for the collection, analysis, categorization, and storage of data in science, research and engineering. They also help scientists to exchange data both internally and internationally with each other. Computers in the government sector are used to perform various functions and improve their services. In most cases, data processing tasks, the maintenance of citizens' databases, and the promotion of a paperless environment are the primary purposes of using computers. In addition to this, computers play a key role in the country's defence system. Health and Medicine-.

It renders output after performing mathematical and logical operations and can save the output for future use. The word "computer" derives from the word "computare" in Latin, which means calculating. Computers are of different types based on different criteria. Based on their size, computers are of five types:.
Micro Computers-. It is a single-user computer that has less capacity for speed and storage than the other types. For a CPU, it uses a microprocessor. Laptops, desktop computers, personal digital assistants PDAs , tablets, and smartphones are common examples of microcomputers. Microcomputers are generally designed and built for general use, such as browsing, information search, the internet, MS Office, social media, etc. Mini Computers-. Minicomputers are also referred to as "Midrange Computers. Therefore, they are generally used by small companies and firms. Mainframe Computers-.
It is also a multi-user computer that large companies and government organizations use to run their business operations as large amounts of data can be stored and processed. Banks, universities, and insurance companies, for example, use mainframe computers to store data from their customers, students, and policyholders. Super Computer-. Among all types of computers, supercomputers are the fastest and most costly computers. They have an enormous capacity for storage and computing speeds and can therefore perform millions of instructions per second.
It is a single-user computer with a comparatively more powerful microprocessor and a high-quality monitor compared to a mini-computer. It increases productivity. It helps in connecting to the internet. It helps in organizing data and information. It allows storing large amounts of data. The first electric computer that was invented weighed around 27 tons or even more than that and took up to square feet. There are about new viruses that are released every month. The original name of Windows was Interface Manager. It is surely known that the life of humans would not have been so easy if computers were not a part of human life.
This is also supported by a lot of pieces of evidence where we can even see in daily life how the computer is not just present in an organization but is also available right in the pockets of everyone. Thus, the computer has surely made it easy while also spoiling a lot of people's lives. Conclusion It is surely known that the life of humans would not have been so easy if computers were not a part of human life.
