2 Client Server Architecture Client server architecture is a common network architecture which connects multiple machines to a server. Server is a computer with higher performance and shares resources with clients. Internet is also a larger network where clients access resources in web servers via web browsers. What is Hosting? Web sites need to be available on web servers to make them available to clients. Required server software has to be installed on web server. We can maintain our own server or we can purchase a web space from a hosting provider to publish our web site. There are some free hosting providers are also available which provide limited facilities. What is domain name? Each machine in a network has an IP address for the purpose of identification. Same way web servers also have an IP. So there is a specific number to identify each web site. Even though we can browse a certain web site with a number, human mind prefers to remember words over numbers. Therefore each number will be identified with a domain name. These names are saved in DNS Servers along with their related IPs. Register a domain name There are several domain extensions available and you can select a certain domain depending on your purpose..com is the most common extension and used for commercial purposes..net,.org,.info are also popular. Other than these there are country specific domain names. Eg :- Sri Lanka -.lk 1. You have to check whether a certain domain name is available to purchase. You can t register it if it is already registered. 2. Then you can fill out the order form and provide the who is data required. 3. Domain is pointed using name server details or IP address of your web server. Normally 2 name servers called primary and secondary are used for this purpose. 4. After transfer the payment, domain will be allocated. A domain will be registered by domain registrars on behalf of you. ICAAN is the authorized body for domain registrations and it has assigned regional registrars. There are other registrars under regional registrars. The domain actually represents a number.
