Chapter 6: Configuring Communications

Overview

•To get a personal e-mail account, you must ‘sign-up’ with an Internet Service Provider (ISP). ISPs usually provide an e-mail account as part of an Internet access package.

•Most ISPs will provide software (e.g. a CD-ROM) which will help you set up Internet access and the e-mail account on a PC.

Important: Some ISPs require that you connect to them using a PC in order to sign-up. If you can’t do this, contact the ISP to find out if you can sign-up without using a PC. If you have Internet access, see www.psion.com/mobile for more details.

DNS

The Domain Name System (DNS) is an Internet service that translates domain (or ‘host’) names into IP addresses. Domain names are alphabetic but the Inter- net is based on numeric IP addresses. Therefore when a domain name is used, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.psionteklogix.com might translate into the IP address 194.129.243.153.

Hostname (or Domain Name)

A unique identifier in alphabetic characters for a network device.

The hostname corresponds to the device’s numeric IP address. For example, www.psionteklogix.com could be the same as the IP address 194.129.243.153.

IP address

A computer’s unique Internet address, e.g. 194.129.243.153, used by computers to communicate with each other.
