A GUI Web screen’s real estate can be divided into:

Internet

Almost everyone with or without a computer is aware of the latest technological revolution destined to change forever the way in which humans communicate, namely, the Information Superhighway, best exemplified by the ubiquitous Internet. Already, millions of people around the world are linked by computer simply by having a modem and an address on the "Net", in much the same way that owning a telephone links us to almost anyone who pays a phone bill. In fact, since the computer connections are made via the phone line, the Internet can be envisaged as a network of visual telephone links.

The World Wide Web, an enormous collection of Internet addresses or sites, all of which can be accessed for information, has been mainly responsible for the increase in interest in the Internet in the 1990s. Before the World Wide Web, the "Net" was comparable to an integrated collection of computerized typewriters, but the introduction of the "Web" in 1990 allowed not only text links to be made but also graphs, images and even video.

A Web site consists of a "home page", the first screen of a particular site on the computer to which you are connected, from where access can be headed to other subject related "pages" (or screens)at the site and on thousands of other computers all over the world. This is achieved by a process called "hypertext". By clicking with a mouse device on various parts of the screen, a person connected to the "Net" can go traveling, or "surfing" through a web of pages to locate whatever information required.

Anyone can set up a site, promoting your club, your institution, your company's products or simply yourself. And what is more, information on the Internet is not owned or controlled by any organization. It is, perhaps, true to say that no one and therefore everyone owns the "Net". Because of the relative freedom of access to information, the Internet has often been criticized by the media as a potentially hazardous tool in the hands of young computer users. This perception has proved to be largely false however, and the vast majority of users both young and old get connected with the Internet for the dual purposes for which it was intended--discovery and delight.

Everyone is aware of the Information Superhighway.

In the past few years, personal computers (PCs) have become better, stronger and faster but so have the bits and pieces you plug into them.

Monitors

If big is better when it comes to screens or monitors, it is also more costly. As with big TVs, big computer screens are expensive. The Americans' touching devotion to imperial measurements still holds in the computer industry, so people still shop for goods by the inch rather than by the centimeter.

Anyone planning to do any desktop publishing with a PC will want a larger screen; increasingly, however, World Wide Web users and game players are also discovering the rewards of a larger monitor.

American medical television series, such as ER, regularly show the hi-technology used in modern US hospitals. A good example is the thin flat screens used on all computers. Know why they have thin, flat monitors？ Because they're LCD, which is less bulky and smaller than the standard CRT, the kind used in television sets. The LCD screens don' t emit any electromagnetic radiation, which could interfere with the heart machines and other sophisticated electronic equipment in hospitals and thereby cause a crisis. LCD screens are lighter, flatter and throw out less heat than CRTs. They are also at least three times the price — and, as such, out of the league of home users.

Scanners

A scanner is a device a bit like a photocopier, which creates a digital image of a page and stores it on disk. These days most scanners handle color images and are beginning to come in quite a variety of shapes and sizes. The scanner market is a great example of the way the ground can shift in peripherals. Scanners used to be expensive pieces of professional equipment; now, they are an increasingly useful addition to the home or small business PC environment.

The most practical home scanners used to be hand-held devices that the user could slowly track across the desired image, strip by strip. Now, however, there is a wide range of both flatbed and sheet-fed scanners available between ＄ 500 and ＄ 1200.

The first application for scanners has been to scan images or photographs, especially for reproduction in publications. Besides scanning images, the other major application for scanners is OCR scanning in printed articles and converting them to text on the PC.

Printers

There are three main types of printers—dot matrix, inkjet and laser. Dot matrix models still have their place in high-volume commercial jobs, but few home and small office users choose them now. They might be cheap, but they are noisy and the results (especially in color) simply aren't very good.

By contrast, inkjet printers have taken the consumer market by storm in recent years. Unlike dot-matrix printers, which hammer pins against a ribbon as a typewriter does, inkjets silently squirt ink onto the page.

Inkjets, however, are slow, and the quality of their printed type isn't as crisp as you want for professional use. So the next step up is a laser printer. Since the introduction of GDI technology—which cuts down the demands on the printer hardware by getting the PC to do the hard work of the printing process—laser printers have come down markedly in price.

Color laser printers are a bit like color laser copiers—they exist, but only in larger offices and specialist graphics businesses. The various kinds of color laser will inevitably get cheaper—but they may be overtaken in the consumer market by new printers on the US market, which turn out glossy prints which look like photographs and are aimed at users of the new computerized, digital cameras.
