Business Communications Networks

A collection of vocabulary flashcards based on important terms and concepts from the Business Communications Networks lecture.

Network Layer

Responsible for addressing and routing of messages to select the best path from computer to computer.

Transport Layer

Links the application layer to the network layer and is responsible for end-to-end delivery of messages.

IP Addressing

The process of assigning unique identifiers (IP addresses) to devices on a network.

OSPF (Open Shortest Path First)

A link state routing protocol used for finding the shortest path in a network.

RIP (Routing Information Protocol)

A distance vector routing protocol that uses the number of hops to determine the best route.

Subnetting

Dividing a larger network into smaller, more manageable sub-networks.

DHCP (Dynamic Host Configuration Protocol)

A network management protocol used to configure devices on IP networks.

DNS (Domain Name System)

The system used to translate domain names into IP addresses.

BGP (Border Gateway Protocol)

A protocol used to exchange routing information between autonomous systems on the Internet.

MAC Address

A unique hardware identifier assigned to network interfaces for communications at the data link layer.

IPv4

Internet Protocol version 4, using 32-bit addresses for devices on a network.

IPv6

Internet Protocol version 6, utilizing 128-bit addresses for a significantly larger address space.

Quality of Service (QoS)

A set of technologies that work on a network to manage data traffic and ensure the performance of critical applications.

Packet Switching

A method of grouping data transmitted over a digital network into packets.

Three-way Handshake

A method used in TCP to establish a connection between a client and a server.

Congestion Control

Techniques used to manage traffic in a network to prevent overload.

Dynamic Routing

Routing that occurs when routing decisions are made at the time of packet transfer based on current network conditions.

Static Routing

Routing that occurs when routes are manually configured and do not change with network conditions.
