2008-08-14T22:21:00.000-07:00

Web Hosting:

A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation.

Types of Web Hosting:

There are several types of hosting

• Free web hosting service
• Shared web hosting service
• Reseller web hosting
• Virtual Dedicated Server
• Dedicated hosting service
• Manage hosting service
• Home server

I would like to introduce you about Free Web hosting service because it is readily available to every person in no cost. You can have your website up in few minutes. Most of free web hosting service providers facilitate user to have full control on the space by using the control panels or FTP account.

How it help companies to provide Free Web Hosting?

Most of web hosting service provide set a specific amount for a user to host a free website. In return few companies require banner ads to be floated on the user website but most of companies claim no banner ads or pop out in the free account. That sounds great but there is hack in that entire scenario. It is obvious that when you require a website to be hosted on any free hosting server you need a domain name (i.e. URL for the website) registered. Most of the free hosting service providers require you following:

1. Register a domain (charged)
2. Domain Transfer (charged)

So if you don’t get a registered you don’t get free web hosting service. So companies are in loss position because it is business. You have to pay for web hosting it is not totally free in most of the cases.

Job Interview Question - (OOP)

2008-08-12T04:29:00.000-07:00

Q: What does OOP stands for?
A: OOP stands for Object Oriented Programming.

Q: What is a Class?
A: A class describes all the attributes of objects, as well as the methods that implement the behavior of member objects. It’s a comprehensive data type which represents a blue print of objects. It’s a template of object.

Q: What is an Object?
A: It is a basic unit of a system. An object is an entity that has attributes, behavior, and identity. Objects are members of a class. Attributes and behavior of an object are defined by the class definition.

Q: What is the relation between Classes and Objects?
A: They look very much same but are not same. Class is a definition, while object is a instance of the class created. Class is a blue print while objects are actual objects existing in real world. Example we have class CAR which has attributes and methods like Speed, Brakes, Type of Car etc. Class CAR is just a prototype, now we can create real time objects which can be used to provide functionality. Example we can create a Suzuki car object with 100 km speed and tubeless tyres.

Q: What are different properties provided by Objectoriented
systems?

A: Following are characteristic’s of Object Oriented Systems:

Abstraction
It allows complex real world to be represented in simplified manner. Example color is abstracted to RGB. By just making the combination of these three colors we can achieve any color in world.It’s a model of real world or concept.

Encapsulation
It is a process of hiding all the internal details of an object from the outside world.

Communication using messages
When application wants to achieve certain task it can only be done using combination of objects. A single object can not do all the task. Example if we want to make order processing form. We will use Customer object, Order object, Product object and Payment object to achieve this functionality. In short these objects should communicate with each other. This is achieved when objects send messages to each other.

Object lifetime
All objects have life time.Objects are created ,and initialized, necessary functionalities are done and later the object is destroyed. Every object have there own state and identity which differ from instance to instance.

Class hierarchies (Inheritance and aggregation)
In object oriented world objects have relation and hierarchies in between them. There are basically three kind of relationship in Object Oriented world:

Association
This is the simplest relationship between objects. Example every customer has sales. So Customer object and sales object have an association relation between them.

Aggregation
This is also called as composition model. Example in order to make a “Accounts” class it has use other objects example “Voucher”, “Journal” and “Cash” objects. So accounts class is aggregation of these three objects.

Inheritance
Hierarchy is used to define more specialized classes based on a preexisting generalized class. Example we have VEHICLE class and we can inherit this class make more specialized class like CAR, which will add new attributes and use some existing qualities of the parent class. Its shows more of a parent-child relationship. This kind of hierarchy is called inheritance.

Polymorphism
When inheritance is used to extend a generalized class to a more specialized class, it includes behavior of the top class(Generalized class). The inheriting class often implement a behavior that can be somewhat different than the generalized class, but the name of the behavior can be same. It is important that a given instance of an object use the correct behavior, and the property of polymorphism allows this to happen automatically.

Job Interview Question - ASP.Net

2008-08-11T04:48:00.000-07:00

Q:What is the sequence in which ASP.NET events are processed ?

A: Following is the sequence in which the events occur:

Page_Init
Page_Load
Control Events
Page_Unload

Q: In which event are the controls fully loaded?

A: Page_load event guarantees that all controls are fully loaded. Controls are also accessed in Page_Init events but you will see that viewstate is not fully loaded during this event.

Q: What are the Application_Start and Session_Start subroutines used for?

A: This is where you can set the specific variables for the Application and Session objects.

Q: Can you edit data in the Repeater control?

A: No, it just reads the information from its data source.
