Unix/Linux Interview question answer 2016.

Question 1: What is the major advantage of a hash table? (Asked by Silicon Magic
Corp. people)

Answer: The major advantage of a hash table is its speed. Because the hash function is to
take a range of key values and transform them into index values in such a way that the
key values are distributed randomly across all the indices of a hash table.

Question 2: What are the techniques that you use to handle the collisions in hash
tables?(Asked by Silicon Magic Corp. people)

Answer: We can use two major techniques to handle the collisions. They are open
addressing and separate chaining. In open addressing, data items that hash to a full array
cell are placed in another cell in the array. In separate chaining, each array element
consist of a linked list. All data items hashing to a given array index are inserted in that
list.

Question 3: In Unix OS, what is the file server? (Asked by Silicon Magic Corp.
people)

Answer: The file server is a machine that shares its disk storage and files with other
machines on the network.

Question 4: What is NFS? What is its job?(Asked by Silicon Magic Corp. people)

Answer: NFS stands for Network File System. NFS enables filesystems physically
residing on one computer system to be used by other computers in the network, appearing
to users on the remote host as just another local disk.

Question 5: What is CVS? List some useful CVS commands.(Asked by Silicon
Magic Corp.people)

Anser: CVS is Concurrent Version System. It is the front end to the RCS revision control
system which extends the notion of revision control from a collection of files in a single
directory to a hierarchical collection of directories consisting of revision controlled files.
These directories and files can be combined together to form a software release.
There are some useful commands that are being used very often. They are
cvs checkout
cvs update
cvs add
cvs remove
