Sysadmin Interview Questions
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
cvs commit
