Computer Networks

The data link layer provides a reliable link between two directly connected nodes, by detecting and possibly correcting errors that may occur in the physical layer.

X.25 is an ITU-T standard protocol suite for packet switched wide area network (WAN) communication.

Tunneling protocols operate at the transport layer, such as carrying non-IP protocols such as IBM's SNA or Novell's IPX over an IP network, or end-to-end encryption with IPsec.

SMTP is the protocol used to transport electronic mail from one computer to another.

The session layer controls the dialogues/connections between computers.

This property of IIS 6.0 limits IIS to support host-header routing only.

This I/O mode in 8255 allows handshake signals to exchange between the microprocessor and peripherals prior to data transfer.

It defines the server's hostname or IP Address.

OSI application layer is responsible for displaying data and images to the user in a human recognisable format and to interface with the presentation layer below it.

Both are the protocols used in WAP model.

This layer is also called WDP (Wireless Datagram Protocol).

Transaction layer provides the simplified protocol suitable for low bandwidth wireless stations by using TCP/IP protocol.

In remote reference layer, Java Remote Method Protocol (JRMP) runs.

HTTP protocols are stateless in nature.
