Exam 1: Introduction to Computer Networks and Data Communications

It is not possible to connect two local area networks so that they can share peripherals as well as software.

The OSI model consists of seven layers: application, presentation, session, ____________________, network, data link, and physical.

____________________ are personal computers or microcomputers where users reside.

The OSI model tells us what kind of wire or what kind of connector to use to connect the pieces of a network.

Telnet is used to allow a remote user to log in to another computer system.

The ____ layer of the OSI model performs a series of miscellaneous functions necessary for presenting the data package properly to the sender or receiver.

The TCP/IP protocol suite does not have rigidly defined layers as the OSI model does.

One of the most explosive areas of growth in recent years has been cellular phone networks.

A dictionary might define "____________________" as the process of coming together toward single point.

The two most common architectures known today are the Open Systems Interconnection (OSI) model and the ____________________ protocol suite.

Network architectures are cohesive layers of protocols defining a set of communication services.

____ is the transmission of multiple signals on one medium.

The ____ was not created by a standards-making organization but by a group of computer scientists.

Connecting two wide area networks requires devices such as high-speed ____.

The TCP/IP ____ layer commonly uses the Transmission Control Protocol (TCP) to maintain an error-free end-to-end connection.

The ____ layer of the OSI model performs end-to-end connection control.

The session layer of the OSI model is responsible for establishing synchronization points.

A(n) ____________________ converts the local area network data into wide area network data.

The application layer of the OSI model is responsible for token management.
