The invention of the computer is considered to be one of the greatest inventions of all time. The modern computer has changed our daily life to some extent. A computer is an integral part of human beings and we can not imagine our lives without the use of a computer.
As there are two sides of the coins there are advantages and disadvantages of computer system in points which we are going to discuss in detail.
Local area network is the computer network that connects computers within the limited area such as schools, colleges or universities. Local area networks, generally called LANs, are privately-owned networks. They provide a useful way of sharing resources between end users. Most computer networks are general purpose networks used for many different forms of communication, but some networks have been built for a very specific purpose. A storage area network, or SAN. Helps to enhance connectivity. Networks connect and link unlimited number of computers.
We will focus on each and every topic briefly. The computer has reached to every section of human society, from schools to hospitals business organizations, institutions everywhere we cannot imagine our daily life without the use of computers.

As there are 2 sides of coins there are Advantages and Disadvantages of computers ::
- Speed
- Accuracy
- Stores Huge Amount of Data
- Online Trading
- Online Education | Distance Learning
- Research
- Forecasting Weather,and Predicting Earthquakes ,Volcano Eruptions
- Produce Employment
- Internet
- In Business
Speed
The speed of computer has made a vital impact on human society before some decades computer were just used for the purpose of some numerical calculations, but nowadays computers are used in virtually every single part of human life.
The modern computer is not just a calculating device anymore with their speed and accuracy it can perform multiple tasks, operations, and complex numerical problems within fractions of second. They can perform about Trillions of instruction per second.
!!!!! That’s unbelievable Speed!!!!!
'It's hardware that makes a machine fast. It's software that makes a fast machine slow.'
People can play songs, perform their documentation work, surf the internet, check emails, search for your requirements on the internet with great speed and accuracy.
The speed is considered as the biggest advantage of computers because it can perform all operations with an incredible speed which can reduce the amount of time spend when working manually.
For Example : It can calculate the salaries of Employees within a fraction of seconds before it would take long hours when done manually by people.
Accuracy
Not only speed but a computer can work with almost 100% accuracy. This is also one of its advantages, as it can perform complex numerical calculations not only with speed but with unbelievable accuracy..
Imagine you have given a task to calculate the gross salary of ten thousand employees with reduction as per the rules and regulations of the organization. That’s not a simple task to calculate the given salaries manually, you are bound to make mistakes and even a small mistake can harm you badly economically.
And now here comes the magic of computers it can perform all the hard work of calculating the salaries of the employees and deduction as per the requirements. You can derive the results at your fingertips within a fraction of seconds when given correct and proper input, with great speed and incredible accuracy.
Hence the big organizations with hundreds of employees working for them use computer-generated bills and payslips.Even in the Government sector, all the manual calculations had been shifted to computers.
Stores Huge Amount of Data
Data storing capabilities of computers these days are “HUGE” as compared to previous years. They can save or store any volume of data or instruction given to them permanently.
Users can recall the data or instructions or information given to them anytime & any place.
The Storing capability of computer is measured in MB (Mega-Bytes), GB (Giga-Bytes), TB (Tera-Bytes)Railways use modern computer for storing their passenger details, route of trains and even their employee's details.India has a population of around 125 cr people, 93% of them have received their aadhaar card issued by the Government of India.

Research
In research computer are used as they can solve tedious mathematical and logical calculations with high speed and amazing accuracy.The scientist prefers the use of computer in their experiments because of their usefulness.The results of experiments can be stored in a computer hard disk permanently and can be recalled any time required.With the use of a computer the speed of research increases, therefore, computers are made an integral part of research and development
Forecasting Weather, and Predicting Earthquakes
The Super Computers are used in weather forecasting, predicting earthquakes, volcano eruptions, the scientist predict the time and hence they can save people from these natural disasters.Super computer are also used in defense, space exploration, nuclear energy etc.
Produce Employment
The computer produces a great number of jobs per year, people don’t want to work manually anymore as this is tedious, time-consuming, and inaccurate whereas the computer works with unbelievably accuracy and speed and it is very reliable.
