Difference between CCITT, IEEE and ISO

                                   CCITT, IEEE and ISO are organizations which define standards which are used for working of hardare or software together. These standards define how to communicate through messages between these hardwares. So the two harwares from different vendors works, this is the magic of these standards. The competition between hardware companies become high so the cost of these hardware automatically decreases. As the companies have more competition so they tend to give more and more features to their hardware and give efficient result. For example you can take the example of memory card of mobiles. In earlier days the memory card comes in low capacity of space and low speed also. Nowadays the momory card of mobile comes with high speed and more space with even low price.

CCITT

                                                    CCITT stands for Consultative Committee on International Telegraph and Telephone. CCITT is United Nation Agency. This organization defines standards for telegraph, telephone and data communication. X25 is one the standard of this organization. X25 is used for wide area network communication. The new name of CCITT is International Telecommunication Union(ITU).

        CCITT vs IEEE vs ISO

IEEE

                                              IEEE is short of Institute of Electrical and Electronics Engineers. IEEE is also used for defining communication protocols. These protocols are used for LAN communication. Example of these protocols are Ethernet, Token bus and token ring.

ISO

                                                 ISO is short of International Standard Organization. It is also used for defining different standards. ISO started in 1926 and it was named as ISO in 1946.

Difference between static, final and abstract class in java

Abstract class

Abstract class

An abstract class is that which must be extended. If you use abstract method in a class then that means the class is abstract also so you have to declare that class as abstract. Abstract class behaves as a template. Abstract class can contain static data. Abstract class can not be instantiated.

Static class

Static class is that whose methods and variables can be called without creating the instance of the class. Static means which is initialized once for example our main method is initialized only once.
We cannot override the static method in child class by non static. So the child class should be static as well.

Final class

Final class is that which cannot be extended and the final variable is constant that means it cannot be changed.

Why to use jquery instead of javascript

                                                                                                                                                                                         

                                              You have already heard about javascript but jquery is little confusing to new coders. The matter of fact is that with the advent of new programming languages it is becoming easier of programmers to code and overcome their needs. Now programmers want that they write less code and have more functionality in the code. With less code in mind, jquery was thought to be created. But first I want to tell you what the heck jquery is. Jquery is also javascript but it is javascript library. That mean some methods are defined in this library that do certain tasks like you want to animate anything then certain method you have to use instead of writing the code from the start.

Jquery vs Javascript

If you have heard about ajax then doing ajax in jquery is very easy. There are many methods in jquery that can do ajax with very little code and is also very easy to undertand the code. Ajax is that data is retrieved or send to other pages while staying on the same page or you can say without page refresh. Now there are many jquery plugins are available which use jquery code at the backend and gives their own task of functionality in it.
You may have heard about different frameworks like codeigniter is php framework which hide many complexity of php code and work in style of writing less code and having more functionality. So jquery is also like a framework which does more and we have to write less code. Javascript is a complex scripting language and doing some tasks become very difficult in it. I had been working on project and was using javascript and the way I want to do something was looking impossible in javascript, so I downloaded jquery library, read some documentation from jquery official website and do some research and finally my work was done and my client also become happy. So hope you also try jquery yourself and you have more fun using it.

Difference between notebook, netbook, laptop and tablet

                                     
                                      There are many types of computers exists nowadays and most users also think that smartphone is also a type of computer. Usually people want to buy laptop and there arises question in their mind that which laptop they want to buy notebook, netbook or traditional named laptop.

Tablet

So today I discuss about the differences between all these computers.

Notebook

Notebook is also called small laptop. It has no internal dvd drive but can be attached through ports. Notebook is thinner than normal laptop. Its battery runs from 4 to 5 hours. Notebook has maximum 14 inch screen and minimum 12 inch screen. It has Celeron processor. They are costly than normal laptops. If the notebook has touch screen then we call them tablet also.

Netbook

Netbook is smaller than notebook and also lighter in size. The keyboard is very small which make us difficult to type. It consumes less memory and power. Netbook has minimum screen of 7 inch and maximum screen of 10 inch. It is mostly used for internet, visiting website, checking emails and social networking.

Laptop

Normal laptop has large screen e.g. 17 inch screen. It has dvd drive internally build in. Laptop occupies large space. It has 2.5 to 3 hours battery timing. The RAM and other parts can be changed if damaged. Laptop has good quality of audio. Consume less power. It is equipped with intel Centrino processor. With the passage of time the laptops become faster and with lot of space so you can perform all the tasks that you do on desktop pc.

Tablet

Tablet has no physical keyboard. It has virtual keyboard. Tablet has long battery timing. It can operate by picking it in one hand and using by another hand. It has touch screen. No cd drive and dvd drive. If you want to install something then there are apps available which you can download from app store. As tablets have less space and processor so it can use some network resources connected through internet.
I don’t think so that tablet is very useful for computing. It is used only for playing games, browsing net.
