Dedicated Server
In the Web hosting business, a dedicated server refers to the rental and exclusive use of a computer that includes a Web server, related software, and connection to the Internet, housed in the Web hosting company's premises. A dedicated server is usually needed for a Web site (or set of related company sites) that may develop a considerable amount of traffic. The server can usually be configured and operated remotely from the client company.
A dedicated server is a single computer in a network reserved for serving the needs of the network. For example, some networks require that one computer be set aside to manage communications between all the other computers. A dedicated server could also be a computer that manages printer resources. Note, however, that not all servers are dedicated. In some networks, it is possible for a computer to act as a server and perform other functions as well.

A standby server is a second server that can be brought online if the primary production server fails. The standby server contains a copy of the databases on the primary server. A standby server can also be used when a primary server becomes unavailable due to scheduled maintenance. For example, if the primary server needs a hardware or software upgrade, the standby server can be used.
a standby SQL Server will have a copy of the main production database, which is as closely in synch with the original database as possible, in terms of transactions.
Since SQL Server provides so many options for copying data between different databases and servers, novice/inexperienced DBAs often get confused, as to which option to go with, for maintaining a standby server. Some of those options include Data Transformation Services (DTS), BCP, Replication, Clustering, Backup/Restore, Logshipping.
