A protocol is a set of communication rules to make sure that everyone speaks the same language.

FALSE

A network interface card (NIC) is a card that plugs into the back (or side) of your computers and lets them send and receive messages from other computers.

TRUE

TRUE

FALSE

Architecture includes peer-to-peer networks and client/server networks.

FALSE

These are examples of network architecture.

FALSE

Architecture includes peer-to-peer networks and client/server networks.

TRUE

TRUE

FALSE

A client is a computer designed to request information from a server. A server is a computer dedicated to providing information in response to requests.

FALSE

A client/server network is a model for applications in which the bulk of the back-end processing, such as performing a physical search of a database, takes place on a server, while the front-end processing, which involves communicating with the users, is handled by the clients.

FALSE

Interoperability is the capability of two or more computer systems to share data and resources, even though they are made by different manufacturers.

FALSE

Ethernet is a physical and data layer technology for LAN networking.

TRUE

TRUE

FALSE

The transport layer handles end-to-end packet transportation.

FALSE

The Internet layer formats the data into packets, adds a header containing the packet sequence and the address of the receiving device, and specifies the services required from the network.

Wire media are transmission materials manufactured so that signals will be confined to a narrow path and will behave predictably.

FALSE

Twisted-pair cable refers to a type of cable composed of four (or more) copper wires twisted around each other within a plastic sheath.

FALSE

Coaxial cable is cable that can carry a wide range of frequencies with low signal loss. It consists of a metallic shield with a single wire placed along the center of a shield and isolated from the shield by an insulator.

A local area network (LAN) is designed to connect a group of computers in close proximity to each other such as in an office building, a school, or a home. A wide area network (WAN) spans a large geographic area, such as a state, province or country. WANs often connect multiple smaller networks, such as local area networks (LANs) or metropolitan area networks (MANs). A metropolitan area network (MAN) is a large computer network usually spanning a city.

Networks are differentiated by the following: (1) architecture—peer-to-peer, client/server, (2) topology—bus, star, ring, hybrid, wireless, (3) protocols—Ethernet, Transmission Control Protocol, and (4) media—coaxial, twisted-pair, fiber-optic.

A peer-to-peer (P2P) network is any network without a central file server and in which all computers in the network have access to the public files located on all other workstations. A client is a computer that is designed to request information from a server. A server is a computer that is dedicated to providing information in response to external requests. A client/server network is a model for applications in which the bulk of the back-end processing, such as performing a physical search of a database, takes place on a server, while the front-end processing, which involves communicating with the users, is handled by the clients.

Network topology refers to the geometric arrangement of the actual physical organization of the computers and other network devices in a network. The five common types found in networks include: (1) Bus—All devices are connected to a central cable, called the bus or backbone. Bus networks are relatively inexpensive and easy to install for small networks. (2) Star—All devices are connected to a central device, called a hub. Star networks are relatively easy to install and manage, but bottlenecks can occur because all data must pass through the hub. (3) Ring—All devices are connected to one another in the shape of a closed loop, so that each device is connected directly to two other devices, one on either side of it. Ring topologies are relatively expensive and difficult to install, but they offer high bandwidth and can span large distances. (4) Hybrid—Groups of star-configured workstations are connected to a linear bus backbone cable, combining the characteristics of the bus and star topologies. (5) Wireless—Devices are connected by a receiver/transmitter to a special network interface card that transmits signals between a computer and a server, all within an acceptable transmission range.

Transmission Control Protocol/Internet Protocol (TCP/IP) provides the technical foundation for the public Internet as well as for large numbers of private networks.

Wire media are transmission materials manufactured so that signals will be confined to a narrow path and will behave predictably. The three most commonly used types of guided media are twisted-pair wiring, coaxial cable, and fiber-optic cable. Wireless media are natural parts of the Earth’s environment that can be used as physical paths to carry electrical signals.
