Technology Questions

If we print any object by using println() or print() methods.

The println() or print() methods internally calls tostring() method and prints the return value of toString() method.

- The traffic can be measured using the size of the files that are transferred from one place to another (server-client). 

- It can also be measured by the size of the file that is being requested by the client from the server. 

- The number of visitors arriving on the website also involve in the measurement of the traffic using the web hosting platform. 

- The advertisements of the sites take more bandwidth to allow more number of users to be on the website. 

- More number of users provides higher traffic on the website thus it requires more bandwidth on the web hosting sites.

A struct is a special C data type that encapsulates other pieces of data into a single cohesive unit. Like an object, but built into C.

The <span> tag is used to group inline-elements in a document.

The <span> tag provides no visual change by itself.

The <span> tag provides a way to add a hook to a part of a text or a part of a document.

EX :

<p>My Car Color is <span style="color:blue">blue</span> </p>

- Infinite file consists of random bits of code that is stored in /dev/random file used to generate the cryptographic keys. 

- Infinite file consists of the source of infinite data that can be used to provide the response in easy manner. 

- Web server consists of the file that is received by the server in this format GET //dev/random HTTP/1.0. 

- Web server provides the continuous data that can be read from /dev/random/ before the web server can run out of the memory. 

- The server crashes out in case it runs out of the memory due to the infinite file type and it is very essential in case of the web security.

For launching an application, we will need to create an intent that explicitly defines the activity that we wish to start. For example:

Code

        Intent intent = new Intent(this, MyTestActivity.class);

        startActivity(intent);

When we add many spaces in the content then HTML remove all space except one space this is Non Breaking Space. To overcome this problem we use “&nbsp”. Suppose we want to add 3 space between two words then we have to use &nbp three time. 

XML, Extensible Markup Language, is an open, text based markup language that provides structural and semantic information to data. XML is a metalanguage that can be used to create other language. It is used to structure and describe data that can be understood by other applications. Using XML, we can separate the user interface from data.

Features of XML :

- XML is a generalized markup language that means one can define his/her own tag sets.

- A valid XML document contains rules and is self-describing.

- The rules that are found in DTD allow the documents to be validated.
