19 9) Compression occurs at the receiver's end and increases the number of bits to be transmitted based on some type of compression scheme.
2330) A LAN is usually the most expensive of networks to set up.
2125) The network layer of TCP/IP supports IP, or Internet Protocol.
2439) A LAN is between a MAN and a WAN in terms of its geographic scope.
2336) A business cannot have both a local area network and a backbone network at the same time.
2121) The layers of the OSI and TCP/IP models do not have many of the same functionalities.
2337) A MAN can be used to connect BNs and LANs.
1910) The session layer is responsible for establishing, maintaining, and terminating communications running between processes or applications across the network.
2229) A network will fall within one of the following four categories: local area network, backbone network, metropolitan area network, wide area network.
2122) The application layer of TCP/IP includes the functionalities of the OSI application, presentation, and session layers.
2127) The four protocols associated with the IP protocol are: the Address Resolution Protocol (ARP), the Reverse Address Resolution Protocol (RARP), the Internet Control Message Protocol (ICMP), and the Internet Group Message Protocol (IGMP).
1913) Whereas the transport layer in the OSI model is responsible for determining if the entire message has been delivered, the network layer is concerned about the delivery of individual packets across network links.
187) E-mail, remote file access and transfer, printing services, various messaging services, and shared database management are all services supported at the data link layer of the OSI model.
22 28) Both the TCP/IP model and the OSI model have the physical layer, but the physical layer is vastly different in each model.
2120) TCP/IP is known as having either a four- or five-layer model.
2123) In TCP/IP, the application layer is also sometimes referred to as the process layer because this is where a protocol stack interfaces with processes on a host machine, enabling that host to communicate across the network.
2124) The transport layer of the TCP/IP model has two key protocols that are identified with it: TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
2335) A backbone network is usually a high-speed circuit that connects all of the networks within the enterprise, allowing them to communicate with each other.
2019) TCP/IP stands for Transporting Computer Protocol/Internet Protocol.
2331) Because LANs typically cross public thoroughfares or property, they are regulated by the FCC or state public utility commissions.
