We will also explore some of the different ways that people use computers in their everyday lives. By the end of this article, you should have a better understanding of what computers are and how they can be helpful in your life.
History of Computer Technology
The history of computer technology is often referred to as the history of information processing. This term was first used by John W. Mauchly in a paper presented at a conference in 1948. Mauchly and his co-author, J. Presper Eckert, built on the work of British mathematician Alan Turing and his concept of the Turing Machine. The Turing Machine was a theoretical device that could perform any mathematical calculation that could be carried out by hand.
Mauchly and Eckert’s computer, called ENIAC (Electronic Numerical Integrator And Computer), was far more than a simple calculator. It was the first machine that could store programs in memory and execute them at high speed. ENIAC was completed in 1945, just in time for the U.S. Army to use it during World War II to calculate artillery firing tables.
After the war, Eckert and Mauchly founded their own company, which soon introduced the UNIVAC (Universal Automatic Computer), the first commercial computer. In 1951, UNIVAC was used to predict the winner of the U.S. presidential election; it correctly predicted Dwight Eisenhower’s victory over Adlai Stevenson.
The history of computer technology is marked by a series of significant technological advances and milestones:
Types of Computers and Their Purposes
There are four main types of computers: desktop, laptop, tablet, and smartphone.
Desktop computers are the most common type of computer. They are designed for use at a desk or table. Desktop computers come in a variety of sizes, from small form-factor models to all-in-one models that incorporate the monitor into the same unit as the CPU.
Laptop computers are designed for portability. They are smaller and lighter than desktop computers, and they typically have longer battery life. Many laptops can be used as a tablet by folding back the screen, or they may have a separate touchscreen display that can be detached from the keyboard.
Tablet computers are designed for portability and touch input. They typically have a touchscreen display and lack a physical keyboard. Many tablets can connect to an external keyboard for additional productivity. Tablet computers typically have longer battery life than laptop computers.
Smartphone computers are the smallest type of computer. They are designed primarily for use with a finger or stylus input, and they typically have shorter battery life than other types of computer.
