Characteristics of Computer

Characteristics of computer- The computer is an electronic device that can perform arithmetic calculations faster. But it does more, as you will see later. This article explains the main functions of the computer and some of its limitations.

 

What is a computer

A computer is an electronic device that systematically responds to specific instructions and executes a pre-recorded list of instructions called programs.

 

It collects the input data, processes it with a series of instructions, provides accurate output results, and stores it in its memory.

All genuine parts of a computer such as a monitor, keyboard, processor that are tangible are called the hardware of a computer.

Instructions installed on your computer called programs are called computer software.

What are the main characteristics of a computer?

Each computer varies in size and capacity, but many standard features or characteristics allow the computer to perform I / O processes efficiently.

 

They are as follows-

 

speed

precision

Warehouse

Versatility

maintenance

automate

reliability

Power to remember

 

Speed ​​-

The swiftness of a computer is the time it takes to accomplish a given task. The computer is running at lightning speed. For example, it takes a second for a computer to do 3 million calculations instead of a person who takes years. As a result, computing speed is now summing in microseconds, nanoseconds, and even picoseconds instead of seconds or milliseconds.

Accuracy –

Computers are programmed and designed so that their results are almost 100% accurate. It performs all tasks with the same precision. The uncertainty of the results is very low, and even if an error occurs, it could be due to incorrect input data or unreliable programs of a programmer. Such errors are known as Garbage In Garbage Out (GIGO), which means that if you give the computer incorrect instructions, you will get bad results.

Storage –

A human brain stores only the essential knowledge and erases the rest. While a computer can store a large amount of data in its internal memory called primary storage, it can quickly access it when needed. However, internal storage is limited, so secondary storage devices like DVDs, USB drives, etc., can store more data. They can be simply ecstatic from one computer to another. If necessary, parts of the total data can shift to the computer’s internal memory. Data in the computer can never circulate and will always be accessible and stored correctly in a systematic format. A computer’s storage volume is calm in kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB).

Versatility –

Besides being precise and conscientious, a computer is also versatile. It can perform several tasks simultaneously if reduced to a particular set of logical steps. A laptop can use for many purposes in different places, e.g., B. to book plane and train tickets, forecast the weather, listen to music and play games. At the same time, you can pay your electricity bills and create a monthly budget. He can create documents, technical sheets, models of houses, dams, etc.

Diligence –

The capacity of a computer to do tasks without getting tired is known as an industry. Computers are very reliable; they never get tired, don’t run out, and lack focus. Unlike humans, you can work for hours and get precise or flawless results. For example, after 2-3 hours people are tired and unable to concentrate because a computer is running until results are available.

Automation –

Automation means working automatically. A computer can operate independently without the person’s intervention using it. Programs can run the computer according to the study and provide precise results. If an error occurs, it also displays error messages and saves logs.

Reliability –

The high reliability depends on a low failure rate and easy maintenance. The results provided by the computer are reliable because the accuracy is close to 100%.

Storage capacity –

The computer can store data or information for many years. It cannot lose the data by itself. A person can restore the data at any time, and the data will stay the same after a certain number of years. It gives the user the autonomy to take the amount of data to back up and delete.

The limits of a computer

Lack of IQ –

A computer is an engine with zero IQ. He has no intelligence. For example, when it delivers a result, it simply relies on the instruction set programmed for it. He cannot tell if these steps were good or bad. So, if the program is malfunctioning, it may also produce incorrect results. Every little task has to be programmed into a computer to deliver results.

Lack of feelings –

Computers have no feelings or emotions. You can’t judge as humans do. Although they have a memory, It cannot function like the human brain. Humans can decide about hunger pangs and other daily activities, while a computer can only operate as directed. You can’t even tell the change between the people who use it. Addiction – A computer cannot make its own decisions. It can calculate many equations in seconds and give accurate results, but the sequence of equations, steps, etc., can only be programmed by the user, not by the computer. The computer cannot use without the instruction manual. It is therefore totally dependent on its user.
