Below are few sample Wipro tech questions. Generally, you can expect few questions which would ask you to explain primary differences between protocols, technologies, languages, concepts etc. Below are four questions for your practice.
Interview Question 1
Can you say few differences between Unicode character encoding and that of ASCII ?
Answer 1
Unicode uses 16 bits to encode characters and symbols whereas ASCII uses only 8 bits. Unicode has become a universal standard due to the fact that they can represent far great letters than ASCII. Unicode can be used hassle free to encode several regional languages other than English.
Interview Question 2
With reference to DBMS like Oracle or Sybase, can you tell the differences between shared and exclusive locks ?
Answer 2
Multiple transactions use shared locks during database read operations (SELECT Queries) as no data modification is involved. However if a transaction wants to change value of column/columns in single or multiple rows, it acquires an exclusive lock which will not be open to other transactions simultaneously.
Interview Question 3
Can you tell the primary difference between applets and conventional web applications ?
Answer 3
Applet is a program that would be downloaded to browser and run on local CPU whereas web applications get executed on server.
Interview Question 4
In the context of memory management schemes, can you tell a primary difference between swapping and paging?
Answer 4
Paging refers to writing and reading individual pages (fixed size) of a program to secondary memory (during program execution). Swapping refers to swap an entire program with another in secondary memory during heavy resource utilization.
