A modern electronic computer is a machine that is meant for

Doing quick mathematical calculations
Input storage, manipulation of outputting of data
Electronic data processing
Performing repetitive tasks accurately E. None of the above

The correct answer is: B. Input storage, manipulation of outputting of data.

A modern electronic computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations automatically. Modern computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks.

Computers are used for a wide variety of purposes, including:

  • Data processing
  • Scientific research
  • Engineering
  • Business
  • Education
  • Entertainment
  • Communication

Computers are also used in many household appliances, such as microwave ovens, washing machines, and refrigerators.

The first electronic computers were developed in the 1940s and 1950s. These early computers were very large and expensive, and they were used primarily for scientific and military purposes.

In the 1960s, computers began to be used for business applications. The first commercial computers were mainframe computers, which were large and expensive machines that were used by large corporations.

In the 1970s, minicomputers were developed. Minicomputers were smaller and less expensive than mainframe computers, and they were used by small businesses and universities.

In the 1980s, personal computers (PCs) were developed. PCs were small, affordable, and easy to use, and they quickly became popular for home and business use.

Today, computers are used in almost every aspect of our lives. They are used in homes, businesses, schools, hospitals, and government offices. Computers are also used in many industries, such as manufacturing, transportation, and healthcare.

Computers have revolutionized the way we live and work. They have made it possible to do things that were once impossible, and they have made our lives easier and more efficient.

Here is a brief explanation of each option:

  • A. Doing quick mathematical calculations: This is one of the things that computers are good at, but it is not their only purpose.
  • B. Input storage, manipulation of outputting of data: This is a more accurate description of what computers do. They can be programmed to perform a variety of tasks, including input, storage, manipulation, and output of data.
  • C. Electronic data processing: This is another term for what computers do. They process data electronically.
  • D. Performing repetitive tasks accurately: This is another thing that computers are good at, but it is not their only purpose.
  • E. None of the above: This is not the correct answer. The correct answer is B.
