As you can read in our long article on computer history, the first computers were gigantic calculating machines and all they ever really did was "crunch numbers": solve lengthy, difficult, or tedious mathematical problems.

Today, computers work on a much wider variety of problems—but they are all still, essentially, calculations. According to the Oxford English Dictionary, the first known use of the word "computer" was in in a book called The Yong Mans Gleanings by English writer Richard Braithwait: "I haue [sic] read the truest computer of Times, and the best Arithmetician that euer [sic] breathed, and he reduceth thy dayes into a short number." This usage of the term referred to a human computer, a person who.

Most people have used a personal computer in their home or at work. They are used for things such as calculation, listening to music, reading an article, writing etc. Hardware. Modern computers are electronic computer hardware.

They do mathematical arithmetic very quickly but computers do not really "think". They only follow the instructions in. For the first time, non-geeks could write programs and make a computer do what they wished.

Jobs and Wozniak incorporate Apple and show the Apple II at the first West Coast Computer Author: Kim Ann Zimmermann. They were elaborate hulking contraptions that often took up the space of an entire room. They also sucked enormous amounts of energy and were notoriously buggy. And since these early computers ran on bulky vacuum tubes, scientists hoping to improve processing speeds would either have to find bigger rooms—or come up with an alternative.

Computer once meant a person who did computations, but now the term almost universally refers to automated electronic machinery.

The first section of this article focuses on modern digital electronic computers and their design, constituent parts, and applications.

The second section covers the history of computing. Computer - Computer - History of computing: A computer might be described with deceptive simplicity as “an apparatus that performs routine calculations automatically.” Such a definition would owe its deceptiveness to a naive and narrow view of calculation as a strictly mathematical process.

In fact, calculation underlies many activities that are not normally thought of as mathematical. The history of computer science began long before our modern discipline of computer science, usually appearing in forms like mathematics or pments in previous centuries alluded to the discipline that we now know as computer science.

This progression, from mechanical inventions and mathematical theories towards modern computer concepts and machines, led to the development of.

Even before the PC, computer manufacturers were conceptualizing portable computers. It was the pound IBM PC Convertible that brought the laptop concept into production in Since then, laptop computers have become smaller and lighter, and their processing power has improved alongside desktop PCs [source: IBM ].

Users can operate their personal computers independently or in cooperation with other PCs or mainframes to exchange data and share resources. We discuss computer networks in detail in a later chapter. Software: Telling the Machine What to Do In the past, when people thought about computers, they thought about machines.

Over the ensuing decades, many corporations created so-called "IT departments" to manage the computer technologies related to their business. Whatever these departments worked on became the de facto definition of Information Technology, one that has evolved over time.

Today, IT departments have responsibilities in areas like computer tech support, business computer network. A Brief History of Web Browsers and How They Work Janu By Alex McPeak 1 Comment We all know the basic functionality of the browser — it’s what connects you with everything on the web.

The computer does its primary work in a part of the machine we cannot see, a control center that converts data input to information output. This control center, called the central processing unit (CPU), is a highly complex, extensive set of electronic circuitry that executes stored program instructions.

Dismissing computer programming as “women’s work,” the men gave the new IBMs to the women of JPL providing them with a unique opportunity to work with, and learn to code, computers. The First Laptop. The Grid Compass was designed in by a Briton named William Moggridge (–) for Grid Systems Corporation.

It was one-fifth the weight of any model equivalent in performance and was used by NASA as part of the space shuttle program in the early 's. As far as technical specs, it featured a K byte bubble memory laptop computer system with a die-cast.

Information systems hardware is the part of an information system you can touch – the physical components of the technology. Computers, keyboards, disk drives, iPads, and flash drives are all examples of information systems hardware. We will spend some time going over these components and how they all work together in chapter 2.

Software. Apple Computers, Inc. was founded on April 1,by college dropouts Steve Jobs and Steve Wozniak, who brought to the new company a vision of changing the way people viewed computers.

Jobs and Wozniak wanted to make computers small enough for people to have them in their homes or offices. Simply put, they wanted a computer that was user.

Parents were encouraged to buy computers for their children to help give them a good start in life. The BBC launched a huge computer literacy project to educate the nation, including television programmes, books, and even its own branded BBC Microcomputer, built by Acorn in Cambridge.

They got to be creative and expand their knowledge of protons, neutrons, and electrons and how they work together.” Team Up to Track Explorers Many teachers love Chromebooks because apps such as Google Docs and Google Slides make it easy for students to collaborate, whether they’re in the same room or across town.
