A network is __.

two or more computer systems linked together by some form of transmission medium that enables them to share information.

Network clients are __.

computers and software that allow users to request resources shared by and hosted on servers.

A Local Area Network (LAN) is __.

a network in a single location.

Wide Area Networks (WAN) are __.

networks in different geographic locations but with shared links.

Wide area networks can also use __.

copper or fiber optic cabling and various types of wireless networking.

A network protocol __.

identifies each host on the network using a unique address.

A packet is __.

a wrapper for each data unit transmitted over the network.

The overwhelming majority of networks use __.

the TCP/IP suite.

Packet switching introduces __.

the ability for one computer to forward information to another.

A router is __.

a host capable of performing this forwarding function.

A packet switching protocol is described as 'robust' because it __.

can automatically recover from communication link failures.

Besides the forwarding function and use of multiple paths, __

dividing data into small chunks or packets.

Transport layer protocols __.

provide communication sessions between computers.

Transport Control Protocol (TCP) __.

provides connection-oriented delivery.

User Datagram Protocol (UDP) __.

provides connectionless delivery.

The application layer __.

contains protocols that provide the communications formats for exchanging data between hosts.

The Internet Protocol (IP) is __.

the primary protocol responsible for the forwarding function.

It provides __.

packet delivery for all higher-level protocols within the suite.

Source IP address __

Identifies the sender of the datagram by IP address.

Time to Live is __.

the number of seconds a datagram is allowed to stay on the network before being discarded.

The network number (network ID) is __.

common to all hosts on the same IP network.

The host number (host ID) __.

identifies a host on a particular network or logical subnetwork.

At the data link layer, each host is identified by __.

the address of its network interface.

The MAC address is __.

assigned to the network adapter at the factory.

The Address Resolution Protocol (ARP) __.

enables this process of local address discovery to take place.

There are protocols to __.

assign names to hosts and networks and to convert these names into IP addresses.

The Domain Name System (DNS) is __.

a hierarchical, client/server-based distributed database name management system.

The purpose of the DNS database is to __.

resolve resource names to IP addresses.

The URL (or web address) __.

contains the information necessary to identify and (in most cases) access an item.

HyperText Transfer Protocol (HTTP) is __.

the basis of the World Wide Web.
