A computer is a tool or device that can perform logical and arithmetic instructions via a set of programs or computer software. The history of modern computers dates back to 1930s, and 1940s, where they were used primarily for executing simple calculations. Nowadays, computers are everywhere: in consumer devices, industries, military, design, and installed in smart homes as control systems. Computers are comprised of both hardware and software components and primarily exist to make work more comfortable and efficient by processing, storing, retrieving information, and providing feedback for the user.

When was the first computer invented?

The first mechanical computer was invented in 1822 by Charles Babbage. This computer does not resemble the computer that we know today. Babbage developed this model, Difference Engine, with the help of Ada Lovelace, considered to be the first computer programmer for her work and notes on the Difference Engine. Babbage never complete a full-scale functional version of the Difference Engine.

What is computer science?

Computer science is the study of computers and computational systems. Computer scientists focus on software and software systems including theory, design, development, and application. The various areas of computer science include artificial intelligence, computer systems and networks, security, database systems, human computer interaction, vision and graphics, numerical analysis, programming languages, software engineering, bioinformatics, and theory of computing.

Why is my computer so slow?

Your computer is probably running so slow due to the following issues: it is running out RAM or disk drive space, has an old fragmented hard drive, or is running too many background programs. It may also run too many programs at startup, not receive Windows or driver updates, have viruses, or has too many special effects and visual features.
