What is the need of registering a domain name for a website? Explain the procedure of domain name registration. (MARCH-2016)
Answer:

If the domain name entered is available then we can register it by paying the Annual registration fees through online.Consider a Post Office, it has two addresses one string address (Irinjalakuda) and one numeric(pin) code (680121). Just like this the website has also two addresses a string address for example www.agker.cag.gov.in and a numeric address (http:/ /210.212.239.70/). We are following string address, hence this domain name has to be connected to the corresponding IP address of the web server. This is done by using ‘A record’(Address record) of the domain. ‘A record’ is used to store the IP address and the corresponding domain name.
Question 2.
Compare shared hosting and VPS. (MAY-2016)
Answer:
Types of web hosting : Various types of web hosting services are available. We can choose the web hosting services according to our needs depends upon the storage space needed for hosting, the number of visitors expected to visit, etc.
1) Shared Hosting : This type of hosting sharing resources, like memory , disk space and CPU hence the name shared. Several websites share the same server. This is suitable for small websites that have less traffic and it is not suitable for large websites that have large bandwidth, large storage space and have large volume of traffic.
Eg: Shared hosting is very similar to living in an Apartment(Villas) complex. All residents are in the same location and must share the available resources(Car parking area, Swimming pool, Gymnasium, play ground, etc) with every one.
2) Dedicated Hosting : A web server and its resources are exclusively for one website that have large volume of traffic means large volume of requests by the visitors. Some Govt, departments or large organizations require uninterrupted services for that round the clock power supply is needed.

Eg: It is similar to living in an Our own house. All the resources in your house is only for you. No one else’s account resides on the computer and would not be capable of tapping into your resourses.
3) Virtual Private Server (VPS): A VPS is a virtual machine sold as a service by an Internet hosting Service. A VPS runs its own copy of an OS (Operating System) and customers have super level access to that OS instance, so they can install almost any s/w that runs on that OS. This type is suitable for websites that require more features than shared hosting but less features than dedicated hosting.
Eg: It is similar to owning a Condo
