The application layer is the seventh layer of the Internet model and specifies the type of connection and the electrical signals that pass through it. True or false?

false- only 5 layers

Network layer functions include: providing services for an application program identifying all hosts in the network dealing with transmission errors regulating the flow of data

_________ is the process of determining the path that a message will travel from sending computer to receiving computer. Packetizing Addressing Routing Interfacing Broadcasting

Routing

With Client-Based Architecture, application software on the client computers contains presentation, application, and data access logic. True or false?

True

Network Address Translation (NAT): operates on a hub, usually connecting two networks together. allows you to use public IP addresses on the internal network. enables private IP networks that use unregistered IP addresses to connect to the Internet. is the feature implemented at Router to protect a network against Denial of Service attack.

enables private IP networks that use unregistered IP addresses to connect to the Internet.

The fourth layer of the OSI model is called the __________ layer. a. network b. transport c. session d. data link e. presentation

False- IPv6 used 128-bit addresses and IPv4 uses 32-bit addresses

In TCP/IP, the parts of the IP address that are used as the network and host addresses are fixed, so the network and host addresses can be determined without more information. True or False

In NDP Neighbor Solicitation does the following task; advertise their presence together with various link and Internet parameters either periodically, or in response to a Router Solicitation message. are used by nodes to respond to a Neighbor Solicitation message. are used by nodes to determine the link layer address of a neighbor, or to verify that a neighbor is still reachable via a cached link layer address. inquire with Router Solicitation messages to locate routers on an attached link.Routers which forward packets not addressed to them generate Router Advertisements immediately upon receipt of this message rather than at their next scheduled time.
