1. Explain hosts and LM hosts file?
The "HOSTS" file contains entries that simulate "A" records in DNS (and PTR records, too). Only DNS-legal names are allowed in this file.

2. What is a blue screen of death? How to trouble shoot the computer in such situation?
I will reboot my machine 3 times. If the problem continues, the 4th time, I will press f2 to enter the setup which will automatically make my machine go through a process called bios. The bios process will read all my hardware and take me to a configuration setup, then I will go on the boot tab or press F12/F8(depending on the computer) and start windows normally. IF THIS DOESNT SOLVE THE ISSUE, then I will reboot my machine, press F12 and enter the safe mode. Once I enter the safe mode, I will type "msconfig" and click on the "startup" then I will click "DISSABLE ALL >Ok>APPLY>RESTART.
IF SAFE MODE DOESN'T WORK:
I will insert the system recovery CD and press F8 or F12. Then I will press "R" for repair, and restore the system.
IF SYSTEM REPAIR DOESNT WORK:
Reinstall
LAST STEP, IF NOTHING WORKS:
Create a ticket for the client and transfer to tier 2.

Windows 2000 and Windows XP are essentially the same operating system (known internally as Windows NT 5.0 and Windows NT 5.1, respectively.) Here are some considerations if you're trying to decide which version to use:Windows 2000 benefits * Windows 2000 has lower system requirements, and has a simpler interface (no "Styles" to mess with). * Windows 2000 is slightly less expensive, and has no product activation. * Windows 2000 has been out for a while, and most of the common problems and security holes have been uncovered and fixed. * Third-party software and hardware products that aren't yet XP-compatible may be compatible with Windows 2000; check the manufacturers of your devices and applications for XP support before you upgrade. Windows XP benefits * Windows XP is somewhat faster than Windows 2000, assuming you have a fast processor and tons of memory (although it will run fine with a 300Mhz Pentium II and 128MB of RAM). * The new Windows XP interface is more cheerful and colorful than earlier versions, although the less-cartoony "Classic" interface can still be used if desired. * Windows XP has more bells and whistles, such as the Windows Movie Maker, built-in CD writer support, the Internet Connection Firewall, and Remote Desktop Connection. * Windows XP has better support for games and comes with more games than Windows 2000.
30. What is the difference between LCD and TFT?
LCD Means Liquid crystal display
TFT means Thin Film Transistor Liquid Crystal Display.
What I think you mean is Active and Passive matrix LCD panels. This is where there is a difference in price. A typical active TFT panel capable of resolutions of just 1024x768 is made up of nearly 2.5 million transistors (commonly known as small 3 legged lumps of silicon found in TV's and most other electronics) eccept in this case, the transistors are etched onto glass, to microscopic precision hence the name "Thin Film Transistor". A normal LCD basicaly has two layers of glass, one with rows, one with columns, this makes up a grid that can be referenced to control each pixel. The control is done with an IC (integrated circuit or silicon chip) on the LCD's circuit board/s. TFT's tend to be quicker ( response time) and nicer to look at in general.
31. Suppose If a customers blackberry stopped syncing their calendar wirelessly, what would you do?
Firstly, we can create a backup on a pc and wipe out device contents,

Options - Advanced Options - Enterprise Activation,
You need a username and password to proceed. Username is your email address and re-activation pw can be generated through bb server by searching the user and right click and set Activation Pw. This should fix the issue.

Hope this is the answer you where looking for.
'Slow' is a relative question, so first determine what the user is experiencing. Is it slow opening applications or while working in them? is this a networked application or local? If it is a website or network application, the tech can try to open it from their workstation. When did this start? Can you check co-workers sitting near you to see if they also report slowness?
Also, ask the user what, if anything, has changed since it was working 'correctly'. Ask if the user is working from the location they normally do -- maybe they are working at an alternate workstation, working from home over VPN or other issue which they might not realize is a factor, so they fail to inform you.
