Network Communication
A simple model used to divide network communication into four layers.
What is TCP/IP model?
A message sent over a local network to all devices on the network. The message does not contain recipient information.
What are broadcast messages?
A shorthand notation for expressing an IPv4 address and subnet mask.
What is CIDR notation?
In TCP/IP version 6, an IP address used when packets are delivered to a group of nodes on a network.
What is multicast address?
Using TCP/IP version 6, a type of IP address used by routers that identifies multiple destinations. Packets are delivered to the closest destination.
What is Anycast address?
A message on TCP/IP network. A PDU might be called a packet or frame.
What is the Protocol data unit.
In TCP/IP version 4, each of the four numbers that are separated by periods and make up a 32-bit IP address.
What is an Octet?
In TCP/IP version 4, an IP address available to the Internet.
What are public IP addresses?
Any device that connects to the network, such as a computer, printer or router.
What is a node?
In TCP/IP version 6, an address used to identify a specific site within a large organization. It can work on multiple links within the same organization.
What is a unique local address?
The primary TCP/IP protocol, used by the Internet layer, that is responsible for getting a message to a destination host.
What is the IP Internet Protocol?
A model for understanding and developing computer -to-computer communication that divides networking functions among seven layers: Physical, Data Link, Network, Transport, Session, Presentation and Application.
What is OSI (Open Systems Interconnection) model?
A technique that substitutes the public IP address of the router for the private IP address of a computer on a private network when the computer needs to communicate on the Internet.
What is NAT (Network Address Translation)?
In TCP/IP version 6, the last 64 bits or 4 blocks of an IP address that identify the interface.
What is an Interface ID?
In TCP/IP version 6, the last block (16 bits) in the 64 bit prefix of an IP address.
What is Subnet ID?
Any private network that uses TCP/IP protocols.
What is an Intranet?
The leftmost bits in an IP address.
What is a Network ID?
In TCP/IP version 4, an IP address used on a private network that is isolated from the Internet.
What are private IP addresses?
In TCP/IP version 6, two or more nodes on the same link.
What are neighbors?
A name that identifies a computer, printer, or other device on a network.
What is host name?
An IP address that indicates your own computer and is used to test TCP/IP configuration on the computer.
What is loopback address?
A group of local networks tied together in a subsystem of the larger intranet.
What are Subnets?
In TCP/IP version 6, a local area network or wide area network bounded by routers.
What is a link?
Using TCP/IP version 6, an IP address assigned to a single node on a network.
What is a Unicast Address?
A name that identifies a network and appears before the period in a website address.
What is domain name?
