Computer Interview Questions Answers

Question 1 :  What is another name for a motherboard? .  

Answer 1 :  A system board is another name for a computer motherboard.  

Question 2 : Are e-mail addresses case sensitive?

Answer 2 : If you're uncertain if an e-mail address is case sensitive it's safe to assume it's not.Typically most Internet Service Providers (ISPs) and e-mail servers are not case sensitive. which means INFO@exammaterial.com is the same as info@exammaterial.com. However, the first portion of an e-mail address (alias/username/group) can be case sensitive. This means if the server is case sensitive logins INFO, info, and Info would all be considered different users and each of those users would have different e-mail addresses.

Question 3 : Are spaces allowed in e-mails?

Answer 3 : Just like a InternetURL no spaces are allowed in an e-mail address. However, names can be broken up using a period; for example, krishan sharma may have an e-mail address: krishan.sharma@exammaterial.com or krishan.s@exammaterial.com because no spaces are allowed in the e-mail address.

Question 4 : Can I fax a document without a fax machine?

Answer 4 : There are a number of fax programs available for faxing documents electronically using your computer's modem, or simply through the Internet. Some popular fax programs include FaxSTF (Mac) and Fax Wizard (Windows). These programs allow you to fax electronic documents such as Word documents or documents you scan into your computer. I would suggest visiting Download.com for a shareware fax program if you don't have one or visiting eFax.com for more information.

Question 5 : Can I network a Macintosh and Windows PC together?

Answer 5 : No matter what kind of Mac or PC you have, you can use them on the same network. However, if you would like the computers to "see" each other on the network so you can transfer files between the two systems, the Mac will need to be running Mac OS X 10.3 or later. Mac OS X 10.3 (Panther) allows the Mac to join a Windows network just like a Windows computer. As long as Windows Networking is enabled on the Windows machine, you can connect it with the Mac. First, make sure you are in the Finder on the Mac (it should say "Finder" next to the apple in the upper-left corner of the screen). Then choose "Connect to Server..." from the Go menu in the menu bar, or use the shortcut Command-K. This will bring up a window allowing you to type in the IP address of the computer you would like to connect to. If you are unsure of the IP address of the Windows machine, click the "Browse" button located near the bottom of the window. Clicking the Browse button opens a Network window in the Finder that shows the current servers on the network. This window can also be opened by clicking the "Network" icon in the left sidebar of any open Finder window. Click the "Servers" icon in the Network window to view all available servers. Any Windows computers with Windows client networking enabled should show up here. Double click the icon for the computer you want to connect to and you'll be prompted to mount a virtual disk on you desktop. You may also have to enter a username and password, if required by the Windows machine. This login can be specified in the Windows networking preferences or you can enter the administrator login for the Windows machine. Once you have successfully connected, a shared drive or folder will appear on your Mac's desktop. Double-click the icon to open the drive or folder and view its contents. You should be able to drag and drop items to and from the window, just like any other folder on you local hard drive.

Question 6 : Can I replace non-ECC memory with ECC memory ?

Answer 6 : ECC (Error Correcting Code) memory is parity memory and non-ECC memory is non-parity. Parity memory has an extra chip on the module that checks for errors in the transfer of information to and from the memory. So if a memory module has an odd number of chips, it is parity RAM. Many motherboards support both ECC and non-ECC memory. Some sources say you can even mix the two types of RAM and the ECC RAM will work as non-ECC memory. However, most memory companies do not support mixing the two types, so try it at your own risk. Since most motherboards will accept ECC memory, it often depends on if your computer's BIOS supports it. You may have to check your computer's manual to find the answer. If you have a choice, non-ECC memory is typically cheaper than ECC memory and works slightly faster. So when in doubt, use non-ECC memory.  

Question 7 : Can someone hack into my computer if it is not connected to the Internet?

Answer 7 : If your computer is not connected to the Internet, there is no way for information to be transmitted to or from the computer over the Internet. If you have a modem connected to a phone line and have your computer set to receive incoming calls, it is theoretically possible for someone to hack into it, but extremely unlikely. The only way for someone to hack into a computer not connected to the Internet or a phone line it is to physically use the computer. While manufacturers may include chips that uniquely identify your computer, they do not put in chips that transmit any kind of information about your system. Any personal information you have on your computer is stored on your hard drive and is safe as long as no one accesses it. Therefore, it is a good idea to require a password to log in to your computer. It is also wise to erase your hard drive and "zero all data" before selling or giving your computer to someone else.

Question 9 : command sets a file's permission in Linux?

Answer 9 :  chmod

Question 10 : Count Number of characters using Pointers? 

Answer 10 :   Answer 5 : #include<iostream.h> void main() { int Char_Count(char *get_string); char *strcount "THIS IS A STRING"; int int_word_count Char_Count(strcount); cout<<"word count is "<<int_word_count; } int Char_Count(char *get_string) { int count 0; if (get_string ! NULL) { for (;*(get_string+count) ! ' ';++count); } return count; }
