Information Technology What is It

The short answer is: A computer is an electronic device that processes and stores data. It is made up of several components, including a central processing unit (CPU), memory, storage, and input/output devices. The CPU is the "brain" of the computer, responsible for executing instructions and performing calculations. The memory stores data temporarily while the computer is running, while storage holds data permanently. Input/output devices allow the computer to communicate with the outside world, such as through a keyboard and mouse for input, and a monitor and printer for output. There are many different types of computers, ranging from small devices like smartphones to large, powerful machines used for scientific research. However, all computers work in essentially the same way: they input data, process it, and output the result. To understand how a computer works, it's helpful to understand the concept of binary. A binary digit, or "bit," is the smallest...

Introduction and History of the World Wide Web The World Wide Web often referred to simply as the Web, is a vast network of interconnected documents and other resources that are accessed via the internet. The World Wide Web was invented by Tim Berners-Lee in 1989 while he was working at CERN, the European Organization for Nuclear Research. Before the invention of the Web, there were already systems in place for sharing information over the internet, such as FTP (File Transfer Protocol) and Gopher. However, these systems required users to know the specific address of the resource they wanted to access, and they were not easy to use. Berners-Lee saw the potential for a more user-friendly system that would allow people to easily access and share information over the internet. He developed the concept of the Web as a way to link together documents and other resources using hyperlinks, which allow users to navigate from one document to another by clicking on a link. To make this v...
