Interview Questions

strstr() returns part of a given string from the first occurrence of a given substring to the end of the string.
For example:
strstr("user@example.com","@") will return "@example.com".

stristr() is idential to strstr() except that it is case insensitive.

Function is an algorithm which can be used any where in the program when required

The intention of the interviewer by asking this question is to discover the pain points for the candidate.

Here this can be explained with an example like this :

The administrative assistant might seem like someone whose job is simply keeping everything filed and organized and scheduled. But they actually are the building block of the entire office, making everyone's lives function more smoothly and with good access to information when they need it.

Sometimes I have so many things crossing my desk at a given time that I can get a bit overwhelmed. When this happens I take a deep breath and focus on prioritizing the work. Then I get a clear head again and can dive back in.

Capitalism is an economic system followed by a country or a society which is characterized by Privately owned businesses, a market economy and profits.

Capitalism is defined as "production for exchange" driven by the desire for personal accumulation of money receipts in such exchanges, mediated by free markets. The markets themselves are driven by the needs and wants of consumers and those of society as a whole in the form of the bourgeois state.

ilk Test is a Functional testing tool product of Seague software. It uses the language called 4GL(fourth Generation Language).

It has 2 components,
Silk Test Agent - Run on remote machine
Silk Test Host - Creating, Modifying, Viewing the scripts

Uses of Silk Test tool:

1. It’s a tool developed for performing the regression and functionality testing of the application.
2. It benefits when we are testing Window based, Java, the web, and the traditional client/server applications.
3. Silk Test help in preparing the test plan and managing them to provide the direct accessing of the database and validation of the field.

Definition: 3G, known as 3rd Generation, is a standard for mobile / cellular phones. It provides the services that fulfill the International Telecommunication Union specifications.

The application services of 3G include wireless voice telephone, mobile internet access, video calls and mobile television – all in a mobile environment.

3G allows simultaneous use of speech and data services
3G provides peak data rates of at least 200 KBits according to the IMT-2000 specification.
Mobile broadband access of several MBits to laptop computer systems, smart phones is provided by latest 3.5G, 3.75G versions.

3G standards:

UMTS:

  -  Universal Mobile Telecommunications System – One of the 3G mobile telecommunications technologies, also being developed into a 4G technology.
  -  Most common form of UMTS uses W-CDMA as an underlying air interface.
  - UMTS also covers Radio Access Network – UMTS Terrestrial Radio Access Network (UTRAN), and Mobile Application Part (MAP).
  -  Users are authenticated via USIM cards (Universal Subscriber Identity Module).

CDMA2000

   -  Also known as IMT Multi-Carrier (IMT-MC), uses CDMA channel access for sending voice, data and signaling data between mobile phones and cell sites.
   -  The standards are CDMA2000 IX, CDMA2000 EV-DOR Rev.0, CDMA2000 EV-DO Rev.A and CDMA2000 EV-Rev.B. They are approved radio interfaces for the ITU’s IMT-2000.

ArrayList and LinkedList both implements List interface and maintains insertion order. Both are non synchronized classes.

But there are many differences between ArrayList and LinkedList classes that are given below.

ArrayList    V/s     LinkedList ::

1) ArrayList internally uses dynamic array to store the elements.

                   Whereas

LinkedList internally uses doubly linked list to store the elements.

2) Manipulation with ArrayList is slow because it internally uses array. If any element is removed from the array, all the bits are shifted in memory.

                   Whereas

Manipulation with LinkedList is faster than ArrayList because it uses doubly linked list so no bit shifting is required in memory.

3) ArrayList class can act as a list only because it implements List only.

                   Whereas

LinkedList class can act as a list and queue both because it implements List and Deque interfaces.

4) ArrayList is better for storing and accessing data.

                   Whereas

LinkedList is better for manipulating data.

- Web browser functions are to provide the resources or information to the user when asked by them. 

- It processes the user inputs in the form of URL like https://www.google.com in the browser and allows the access to that page. 

- URL is used to identify the resources and fetch them from the server and displays it to the client. 

- It allows the user to interact with the web pages and dynamic content like surveys, forms, etc. 

- It also allows the user to navigate through the complete web page and see its source code in the HTML format. 

- It provides security to the data and the resources that are available on the web that is by using the secure methods.
