81. Have you ever used software to make a work related presentation?
Applicant should have experience of making presentation and of using PowerPoint.
82. What is the major advantage of a hash table?
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.
83. What are the techniques that you use to handle the collisions in hash tables?
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.
84. In Unix OS, what is the file server?
The file server is a machine that shares its disk storage and files with other machines on the network.
85. What is NFS? What is its job?
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.
86. What is CVS? List some useful CVS commands.
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
87. Write a simple Windows Forms MessageBox statement.
System.Windows.Forms.MessageBox.Show
(\"Hello, Windows Forms\");
88. Can you write a class without specifying namespace? Which namespace does it belong to by default?
Yes, you can, then the class belongs to global namespace which has no name. For commercial products, naturally, you wouldn’t want global namespace.
89. You are designing a GUI application with a windows and several widgets on it. The user then resizes the app window and sees a lot of grey space, while the widgets stay in place. What’s the problem?
One should use anchoring for correct resizing. Otherwise the default property of a widget on a form is top-left, so it stays at the same location when resized.
90. How can you save the desired properties of Windows Forms application?
.config files in .NET are supported through the API to allow storing and retrieving information. They are nothing more than simple XML files, sort of like what .ini files were before for Win32 apps.
