It is vital to protect your computer from viruses and attacks over the Internet (see Internet Security Offer on page 

15 and Security on page 28). An comprehensive Internet security program is proposed when you first start your 

computer. You should activate this protection as soon as possible, certainly before you connect to the Internet.

Using the Internet has become a natural part of daily computing. Just a few simple steps can 

connect you to a vast collection of knowledge and communication tools. To accomplish 

these steps you should first select an Internet Service Provider (ISP), which supplies the 

connection between your computer and the Internet. You should research the ISPs available 

in your region, not forgetting to talk to friends and family about their experiences or to 

check reviews and consumer reports. The ISP you select will provide instructions on how to 

connect to the Internet (you may need additional software or a special ‘box’ that connects 

to your phone line).

Depending on your computer model, your location and your communication needs, you have several ways to 

connect to the Internet. 

Some computers include a telephone dial-up (‘modem’) connector. This allows you to connect to the Internet using 

your telephone line. With a dial-up connection, you cannot use the modem and the telephone simultaneously on a 

single phone line. This type of connection is recommended only if you have limited use of the Internet as the 

connection speed is low and connection time is typically charged per hour. 

DSL (Digital Subscriber Line) is an ‘always-on’ connection that runs over the phone line. As DSL and phone do not 

use the same frequencies, you can use your telephone at the same time you are connected to the Internet (this 

requires a ‘micro-filter’ on each telephone socket to avoid interference). To be eligible for DSL, you must be located 

near an DSL-equipped phone exchange (service is sometimes unavailable in rural areas). Connection speeds vary 

depending on your location, but DSL generally provides very fast and reliable Internet connection. As the 

connection is always-on, it is generally charged at fixed monthly rates. 

A cable connection provides fast and ‘always-on’ Internet service via a cable television line. This service is generally 

available in large cities. You can use your telephone and watch cable TV at the same time you are connected to the 

Internet. 

A 3G connection allows you to use cellular networks (such as those used by a mobile phone) to connect to the 

Internet while away from home. The socket for a SIM card may be built in to your computer, or may require an 

external device, such as a USB modem or even an appropriately equipped mobile phone.
