What is Service pack..?

A service pack (in short SP) is a collection of updates, fixes and/or enhancements to a software program delivered in the form of a single installable package. Many companies, such as Microsoft or Autodesk, typically release a service pack when the number of individual patches to a given program reaches a certain (arbitrary) limit. Installing a service pack is easier and less error-prone than installing a high number of patches individually, even more so when updating multiple computers over a network.

Difference between .ost and .pst

The difference between an .ost file and a set of .pst files is that the .ost file starts as a mirror image of your folders on the Exchange Server, and works in conjunction with the Exchange Serve during synchronization. A set of .pst files, on the other hand, is simply a storage location on your hard disk or a server other than the Exchange Server.

When you work offline, you can add, delete, and modify the contents of an .ost file exactly as you would with a folder on a server. For example, you can change and move items in your offline Inbox, send messages that are placed in your offline Outbox, and read your offline public folders. In the meantime, information on the server is still processing. You continue to receive new messages in your mailbox while other users can add, delete, and change items in public folders. However, you are not be aware of these changes on the server until you connect to the network.

When you need to update the contents of the .ost file and its corresponding server folder so that they are identical, you synchronize the folders, and then continue to work offline. In Outlook 2002, this is done through Send/Receive Groups. Synchronization connects to the server through Dial-Up Networking, copy the changes made in each folder to the other folder, and then disconnect. An item that you delete from either the .ost file or the corresponding server folder is deleted from both after synchronization.

You have made it much clearer as to what the role of an .ost file is - thanks - but in the jobs I have had, if a user calls in a panic to say he can't see his inbox, etc we always needed to locate the pst file - not the ost file.

Yet if the pst file is 'simply a storage location on your hard disk', wouldn't it make more sense for users to concern themselves about their ost file, especially if it
works in synchrony with the server simply by pressing Send/Receive Groups?

LG Electronics launched the DM50D 3D-capable monitor

In another innovative move, Korean manufacturer LG Electronics has launched the DM50D 3D-capable monitor which comes with a built-in digital TV tuner. The monitor/HDTV hybrid features the company’s passive Cinema 3D technology, and will appeal to those who dislike the idea of having to wear active-shutter 3D glasses which can be relatively cumbersome. LG’s Cinema 3D displays use polarized 3D glasses that are lighter, more comfortable to wear, and do not require synchronisation, charging nor batteries.

The LG DM50D offers high refresh rates, and as such has been certified as “Flicker Free” – an added bonus because it places less strain on the eyes of users looking to enjoy 3D gaming and viewing. Viewers will also purportedly benefit from reduced crosstalk artefacts when watching extra-dimensional content, which is important to keep eye fatigue to a minimum. For four-eyed folks a clip-on style is available, which can simply be attached onto standard prescription lenses. Si-hwan Park, vice president of the monitor division at LG’s Home Entertainment Company, said that the company had carried out research which revealed that many people are not happy about wearing the more cumbersome 3D glasses, while some have concerns about their health when using these glasses.

The monitor itself features 2D-to-3D conversion capability, which will work automatically with games, and regardless of whether it is hooked up to a PC. LED backlight technology and HDMI connectivity will come as standard. Users will also be able to watch videos from a flash drive without the need to boot up the computer thanks to the USB Quick View feature of the DM50D.

The new offering from LG effectively provides consumers with a cross between a PC monitor and a personal 3D TV. Surprisingly, the Seoul-based corporation remains coy on the actual screen size, but judging from the model number it could be either 50 inches or 50 centimetres (20 inches), with the latter being more likely given that the 3-dimensional television/monitor is meant to “fit easily on a desktop”. The LG DM50D is scheduled to hit the shelves in Europe from July before being rolled out on a global basis.
