Major Features of Computer 

As discussed above, Computers are complex machines that can perform a wide range of tasks. Now to understand how things work internally, we must have some knowledge of its features. 

Below are some of the important features: 

Top 8 Features of Computers

1. Speed

Computers are very fast. They are capable of processing a large amount of data at high speed. 

  • Generally, computers can connect to other devices and networks that allow fast data transfer and communication. 
  • They also have the ability to multitask, run multiple programs and applications simultaneously, and execute complex algorithms in real-time.


A computer can load a webpage quickly, which allows the user to view the content without delay.

2. Accuracy

Computers are highly accurate. They operate in the binary system of 0s and 1s, which allows for precise calculations and data manipulation. 

  • They also have built-in error correction mechanisms to ensure data is accurately processed and stored. 
  • Computers can perform repetitive tasks with a high level of consistency, minimizing errors caused by human error or fatigue.
  • With the help of various sensors and input devices, computers can also gather and analyze data with a high degree of precision, providing accurate results for scientific and engineering applications.
  • You can compare the accuracy of a computer with a calculator. As a calculator performs its tasks with full accuracy, a computer also does the same and provides an accurate result.


A computer can accurately calculate a person's monthly paycheck based on their hours worked and hourly rate.

3. Consistency

Consistency refers to the ability of a computer to work in a reliable and predictable manner. Consistency allows the computer to perform at the same level of performance regardless of the workload or usage conditions. 

  • This includes the stable and reliable operation of hardware components, consistent execution of software applications, and dependable data storage and retrieval.
  • Consistency is one of the important features of a computer for ensuring that the computer can be relied upon for critical tasks and applications, and for minimizing the risk of errors or failures that can disrupt productivity or cause data loss.


A computer program generates the same result every time it is run, ensuring consistency and reliability.

4. Logical

The logical features of a computer refer to its ability to process information and execute operations in accordance with logical rules and principles. 

In other words, the computer is able to perform tasks and make decisions based on a set of logical procedures or algorithms.

Some examples of logical features in computers include:

  • Boolean operations 
    The computer is able to perform logical operations such as AND, OR, and NOT to manipulate binary data and make decisions based on that data.
  • Programming languages
    The computer is able to understand and execute instructions written in programming languages, which are designed to express logical procedures and algorithms.
  • Data structures
    The computer is able to organize and manipulate data in logical structures such as arrays, lists, and trees, which enable efficient processing and retrieval of information.

A computer program that controls a robotic arm used in manufacturing. The program must be able to follow a set of logical rules to precisely move the robotic arm in a certain way to complete a task, such as assembling a product.

5. Reliability

Reliability refers to its ability to consistently perform its planned functions without errors or failures. A reliable computer is one that operates as expected and delivers consistent performance under a variety of conditions and workloads.

The key reliability features of a computer are:

  • Hardware stability
    The computer's hardware components should be designed and manufactured to withstand normal usage conditions and provide consistent performance over time.
  • Error correction
    The computer should have built-in mechanisms to detect and correct errors that can occur during the processing or storage of data.
  • Backup and recovery
    The computer should have reliable backup and recovery mechanisms to protect against data loss or corruption due to hardware or software failures.
  • Security
    The computer should have robust security features to protect against unauthorized access or malicious attacks that can compromise the system's reliability.


A computer has a backup system to prevent data loss in the event of a power outage or other failure.

6. Versatility

Versatility in the features of a computer refers to its ability to perform a wide range of tasks and functions and to adapt to different requirements and workloads. 

A versatile computer is one that is able to run multiple software applications, perform various types of data processing and manipulation, and support different hardware components and peripherals.

The key versatility features of a computer are:

  • Operating system compatibility
    The computer should be able to run different operating systems and software applications, which allows users to choose the tools and applications that best suit their needs.
  • Hardware compatibility
    The computer should support a wide range of hardware components and peripherals, such as printers, scanners, and external storage devices, which enables users to expand their capabilities and customize their setup.
  • Multi-tasking
    The computer should be able to handle multiple tasks and processes simultaneously, which improves productivity and efficiency.


A laptop can be used for both work and entertainment purposes, such as browsing the internet and playing video games.

7. Automation

A computer is an automatic machine. Generally, the computer performs all its tasks automatically, which means that once the computer starts a task, it does the job without any human intervention. 

You can compare the automation of a computer to a vending machine. As the vending machine can automatically perform its tasks, the computer also does the same.


A program inside the computer automatically updates the software and security settings to keep it safe and up-to-date.

8. Remembrance Power

A computer is capable of storing an infinite amount of data or information. It has a high remembrance power. It is one of the important features of the computer.

  • Any information can be stored and retrieved for as long as you need it, for an infinite number of years. 
  • It is entirely up to you how much data you want to store on a computer and when you want to lose or rescue it. 
  • You can compare the remembrance power of a computer to a diary. As the diary stores the information and retrieves it when needed, the computer also does the same.


A computer can store a person's important documents and files, allowing them to access them easily when needed.

Frequently Asked Questions

What are the 4 main features of a computer?

The four main features of a computer are its processing power(the ability of the CPU to perform), its storage capacity(RAM and ROM), input-taking capacity(interaction with the user), and its capability to provide correct output. These are the building blocks of a computer.

What is processing power in a computer?

Processing power refers to the ability of a computer to perform calculations and execute instructions efficiently and quickly. It is mainly the capacity of the CPU(Central Processing Unit). It determines how well the computer can handle a task.

What is the storage capacity of a computer?

Storage capacity is the amount of data stored on a computer. A computer has primary and secondary memories. The volatile primary memory(RAM) is where instructions are stored to get executed. And the secondary memory is the non-volatile storage for long-term storage.

What are software applications in a computer? 

Software applications in a computer are the applications that perform certain tasks on a computer. They can perform a wide range of activities as per their use. The operating systems, browsers, MS Word, multimedia software, utility software, development tools, DBMS, etc., all come under it.
