ADDRESSING IN INTERNET

The Internet address is often referred to URL (Uniform Resource Locator) and usually written in the order:

protocol://domain/directory/file
www = world wide web

Example URL:

http://www.smpn1jtspo.sch.id

http://www.upi.ac.id/pascasarjana/syarat_pendaftaran.htm

where,

·         Protocol – to define the communication procedures used. Protocols often used are http, https, ftp.

·         Domain – is the name of the server / computer that provides services.

·         Directory – is a folder to save information.

·         Files – files that are stored (sometimes do not have to be written).

For the purposes of electronic mail (e-mail) or telephone on the Internet, typically address written using the format:

username@machine name in internet

20281@voiprakyat.or.id 

UNDERSTANDING DOMAIN

Communication can be done with all the computers in the world if every computer in
Internet networks has a number, like a phone. These numbers should be unique,
and written in the format of four sets of numbers, example 202.123.41.52. The number is usually
known as an IP address. So, computers can communicate with each other
using the IP address.

Unfortunately, humans are not very good to remember many numbers of IP addresses. To facilitate the human, it is developing a domain name that represents the name of a computer on the Internet. Examples of domain names are:

1.      www.ipl.org - Internet Public Library on the Internet.

2.      www.plasa.com - Plasa Telkom.

We know some of the Top Level Domain (TLD), such as:

·        .com – for commercial organizations

·        .org – for non commercially organizations

·        .gov – for the United States governments

·        .edu – for university

·        .id – Indonesia

·        .sg – Singapore

·        .jp – Japan

·        .au – Australia

·        .co.id – for commercial organizations in Indonesia

·        .or.id – for non commercial organizations in Indonesia

·        .ac.id – for university in Indonesia

·        .sch.id – for school in Indonesia

1.       Individual connection or only one computer

·         Dial-up Modem

·         WiFi Hotspot especially in laptop

 

2.       Office connection which consists of many computers at once
