True

ANSI is a voting participant in the ISO.

True

According to John Chambers, CEO of Cisco (a leading networking technology company), the information age is the second Industrial Revolution.

True

At the transport layer in the Internet model, TCP is responsible for breaking large files received from the application layer into smaller messages and opening a connection to a server for transferringthem.

True

Data communication standards enable each layer in the sending computer to communicate with its corresponding layer in the receiving computer.

True

Due to advances in high speed communication networks, the information lag, or the time it takes for information to be disseminated around the world, has been significantly shortened.

True

In the OSI model, the application layer provides a set of utilities for applications and is the end user's access to the network.

True

It is not uncommon for companies to end up spending more money on network management and security tasks than they do on the actual computer equipment itself.

True

Telecommunications is the transmission of voice and video as well as data and usually implies transmitting a longer distance than in a data communication network.

True

The specification stage of the de jure standardization process consists of developing nomenclature and identifying the problems to be addressed.

True

session, presentation and application

The three stages of the de jure standardization process are ______________________.

specification, identification of choices and acceptance.

Which of the following is not a function of the data link layer?

specifying the type of connection, and the electrical signals, radio waves, or light pulses that pass through it

store data and software programs that can be used by client computers on the network.

The fourth layer of the OSI model is called the __________ layer.

transport

Which layer of the OSI model is responsible for ensuring flow control so that the destination station does not receive more packets that it can process at any given time?

transport

Which layer of the OSI model is responsible for ensuring that all packets sent are received by the destination station by dealing with end-to-end issues?
