what is computer? explain characteristics & applications of computer
Answers
The characteristics of computers that have made them so powerful and universally useful are speed, accuracy, diligence, versatility and storage capacity. Let us discuss them briefly. Computers work at an incredible speed. A powerful computer is capable of performing about 3-4 million simple instructions per second.
Answer:
Computer: A computer is a machine that typically processes data in accordance with a set of instructions. The digital computer conducts mathematical and logical operations at extremely fast speeds and stores data in discrete units.
Explanation:
A machine that can be programmed to manipulate symbols is a computer. Its main traits are as follows: It reacts in a clearly defined way to a given set of instructions. It can carry out a set of recorded instructions (a program).
Characteristics of computer system:
1. Speed
A computer is a very quick machine. It can complete the instructions in a very little amount of time. Computer speeds are measured in microseconds, nanoseconds, and even picoseconds. To learn more about measurement units, see here.
2. Accuracy
A computer can never make a processing error. i.e., a computer is an entirely accurate device. Only when we (users) give the computer incorrect input or instructions will a computer produce the incorrect results. Therefore, a computer is also referred to as a GIGO (Garbage In Garbage Out) machine.
3. Versatility
The ability of a computer to carry out many activities with the same level of accuracy and effectiveness is referred to as versatility. A computer is a multitasking device that can carry out multiple tasks at once.
4. Diligence
The computer is free from fatigue and loss of focus. It can operate for several hours without making any mistakes. A computer has the quality of diligence, thus it will never grow weary of performing the same job repeatedly. Additionally, it will carry out each task precisely.
5. Reliability
The computer's output and results are quite trustworthy. The ability of a computer system to carry out its intended function for a predetermined amount of time with the same accuracy is known as computer reliability
6. Huge Storage
The computer contains internal memory that can accommodate a considerable amount of data. Data can also be kept on a secondary storage device, such as a hard drive.
Applications of computer:
Home
Computers are used in homes for a variety of activities, including online bill payment, home entertainment, home learning, access to social media, gaming, and internet. They offer email as a means of communication. They support offering corporate employees the option of working from home. The student population can access online instructional support with the aid of computers.
Medical Field:
In hospitals, computers are used to keep a database of patient information, including their medical history, diagnoses, X-rays, and real-time patient monitoring. Today's surgeons do remote procedures and delicate operations using robotic surgical tools. Technologies related to virtual reality are also applied to training. Monitoring the developing fetes inside the mother's womb is also helpful.
Industry:
Computers are utilized in many different businesses for functions including inventory management, designing, making virtual samples of products, interior design, video conferencing, etc. The potential of online marketing to offer diverse products to hard-to-reach places like interior or rural areas has undergone a significant revolution. Through the use of computers, stock markets have witnessed amazing engagement from individuals at all levels.
Entertainment
Computers provide virtual entertainment by allowing users to play games, watch movies online, and listen to music, among other activities. People working in the entertainment sector can record music using artificial instruments with the use of MIDI instruments. Computers are capable of feeding videos to large-screen televisions. There are wonderful features in photo editors.
Government
Computers are employed in the government to handle data, keep a database of citizens, and enable a paperless workplace. The employment of computers by the nation's defense institutions for the development of missiles, satellites, rocket launches, etc. has been extremely advantageous.
Banking
Computers are utilized in the banking industry to store customer information and carry out operations like ATM withdrawal and deposit. Banks now use computers a lot more, which has greatly reduced manual errors and costs.
Business
Computers are now completely integrated into business. Transaction processing, which includes dealings with suppliers, staff, or consumers, is the primary goal of business. These transactions can be made simple and accurate by computers. People can use to examine investments, sales, costs, markets, and other business-related elements.
