Basic Applications of Computer
A computer is a device that allows you to accomplish a wide range of tasks through its use. Changing the software packages on your computer gives you the ability to use it for a variety of different applications. The following is a list of purposes or applications that computers can be put to:
- Scientific research
- Business application
- Book Publishing
The following is a graphical depiction of the aforementioned list of applications that can be carried out with the assistance of a computer.
Now let's quickly go over each of the 12 fundamental uses of computers that were listed above, one at a time.
For Scientific Research
Scientific research was the first application of computers, as computers were first used to perform this job, namely, scientific research. From that time until now, the speed and accuracy of computer-enabled scientific analysis have been carried out too quickly.
Computer-controlled robots must be used in all those areas where there is danger to humans, such as in nuclear research and deep sea investigation, etc.
For Business Application
It is possible to use a computer for professional purposes as well.
With the use of computers, businesses are able to expand their operations as rapidly as possible. This is accomplished by performing a prompt analysis of their previous projects on the computer screen (based on the data provided into the system), and then deciding what to do next without any lag time.
Everyone from sole proprietors to multi-national corporations uses computers for many business-related tasks, including the maintenance of account information, the monitoring of stock levels, the calculation of prices, and the listing of products.
You can also use your computer system to educate yourself through audio, videos, images, etc.
Nowadays, there are thousands of websites available on the Internet that offer free education in almost every subject.
You have the option of learning in either an online or traditional setting. When it comes to offline learning, you have the option of learning through movies, PDFs, photographs, and other media that can all be downloaded from the internet. On the other hand, when it comes to online learning, you may access any website to read about the subject of your choice.
The majority of people use computers for various forms of entertainment, including the following:
- watching movies
- watching videos
- listening to music
- animations etc.
It is possible to use a computer to design these items in an appealing style in order to ensure that the user will love using them.
It is possible to argue that banks are the most significant consumers of computers because this is the setting in which computers are utilized on a continual basis. An example of this would be the use of an automated teller machine, often known as an ATM, which allows us the flexibility to either deposit or withdraw cash from our bank account.
Computers are used at banks to manage all of the information that is stored there, including facts about account holders, deposits, withdrawals, interest, and so on.
Banks are also making use of computer networks to integrate all of their branches, which enables their customers to deposit their money at any branch of the same bank without feeling restricted in their options.
There are a lot of advantages that come along with employing your computer system for the purpose of communicating. For instance, if you use email to send messages or anything else to your friends or any of your contacts, you don't have to use a pen and paper to write it and then take that paper to the post office, where the postman will deliver it later, after some or a few days, which is not ideal if you want to send any urgent information to the same person. If you use email, you don't have to take that paper to the post office, where the postman will deliver it later.
As a consequence of this, using email enables you to save both time and money while simultaneously accelerating the delivery of information.
People communicate with one another using a variety of mediums these days, including chat messages, email, voice mail, and so on.
You are able to use a computer to engage in direct video conference communication with your connections or acquaintances located in any location, and the only expense you will incur is the cost of maintaining internet connectivity.
You should now have a solid understanding of how people communicate using computers. It is time to move on to yet another application of computers, this time in the field of engineering.
For Engineering Purposes
Computers are also used for the purpose of engineering, that is, to design any machine without actually making it through CAD (computer-aided design) software, and once the design is accepted, then using a CAM (computer-aided manufacturing) process, a company can produce a large number of such products at a very fast speed.
Architects are also using computers to draw and design everything from individual houses to big buildings like apartments. There are numerous other applications for computers in engineering.
For Medicines Related
Computers also play an important role in the medical field.For example, in the ICU (Intensive Care Unit) chamber in a hospital, a computer keeps track of everything going on inside the patient's body, such as blood pressure, heartbeat, etc.
Keeping records of patients and medicines also becomes easier with the use of computers. The computer is also used to perform CT (computerized tomography) scans and X-rays on patients in order to provide the scanned object of a specific area of the patient's body in the form of graphics-like images.
For Book Publishing
With the use of computers, book publishing becomes a simple task.
Book publishers are now using DTP (desktop publishing) software like MS-Word to publish their books.
People nowadays spend the majority of their time playing video games on computers.
For online games to be played, you must have internet connectivity, whereas for offline games, you can start without any internet connectivity.
There are a variety of games available in the computer world. Here are some of the categories available in the game field:
- combat etc.
People spend a few to many hours playing computer games (mostly modern or new generation children's). Some popular games are listed here:
- Counter Strike
- Grand Theft Auto
- Angry Bird
- Call of Duty
- Super Mario Bros etc.
For Personal Use
A computer can also be used for personal purposes.
A computer system can be used to keep all of the day-to-day details that are necessary to keep anywhere.
You can use it for personal things such as investments, incomes, expenditures, savings, etc.
For Accounting Purposes
Computers are highly used for accounting purposes to handle company financial accounts and inventory management using accounting software like Tally.
With the use of computers, the task of maintaining accounts becomes very easy. Later, you can also retrieve the data on the basis of various patterns or requirements very easily.
