REMOTE DESKTOP

You can use Remote Desktop Connection (RDC) to connect to a remote computer on your network or the Internet and use the remote computer as if you were physically in front of it. Before you can connect toa remote computer, it needs to be turned on (available for a network connection). It also has to be set up to allow users to connect to it remotely. You can allow anyone to connect to the remote computer, or you can specify users with a password. After the remote computer is set up, you can use RDC to connect to it. When the RDC dialog box opens, you need to have the name or IP (Internet Protocol) address of the remote computer and, if required, the username and password specified on the remote computer for security purposes. In the RDC dialog box, you can also customize settings for the remote connection, which include the display size and color depth, when to use local or remote resources, and what programs to use and options to allow. Once you connect to the remote computer, the remote desktop appears on your screen and is ready to use.

File System

File system is a way of organizing files on a storage device like a hard disk drive, pen drive, memory card, DVD writer, DVD drive, CD ROM and other removable devices.

Types of file system

1)   FAT (File allocation table)

·         It is 32-bit file system

·         FAT provides user level security

·         No security like in NTFS

·         FAT supports drives upto 2TB

2)   NTFS (New technology file system)

·         It is 32 & 64 bit file system

·         NTFS provides data level security such as data compression, data encryption, data (disk) quota

·         NTFS supports high level authentication protocol for managing the logical server OS.

·         Shadow copies feature utility is also provide in NTFS in server OS only.

·         Disk quota reserves the space in the server to user in a particular day.

 Soft quota (we can set a warning eg.100MB for 1GB)

Hard quota (in this quota the system stops working eg. At 1024MB we can set hard quota)
