Text A: Network advantages and challenges

In the early years of the personal computer’s popularity, networks were scarce. Most personal computers functioned as standalone units.

Today, the pervasiveness of network has dramatically changed the face of computing by offering shared resources – hardware, software, and data made available for authorized network users to access. Networks offer the following advantages:

· Sharing networked hardware can reduce costs.

· Sharing networked hardware can provide access to a wide range of services and specialized peripheral devices. A network can allow multiple users to access internet services through a single internet connection. Networked peripheral devices, such as scanners, photo printers, plotters, high-capacity storage devices, and computer-aided manufacturing (CAM) equipment, can be accessed by any authorized network users.

· Sharing data on a network is easy.

· Networks enable people to work together regardless of time and place.

The primary disadvantage of networks is their vulnerability to unauthorized access.

Networks are more vulnerable than standalone computers to malicious code. Whereas the most prevalent threat to standalone computers is disk-borne viruses, networks are susceptible to an ever-increasing number of worms, Trojan horses and blended threats.

Most computer owners are enthusiastic about the benefits provided by networks and believe that those benefits outweigh the risks of intrusions and viruses.
