Hub

Unlike a hub, a ______ is intelligent. It can actually learn the physical addresses of the devices that are connected to it and it stores these physical addresses in its table.

switch

A device that routes or forwards data from one network to another based on their IP address. It is the gateway of network

Router

• Local, per router function •Primarily forwarding and moving a datagram from an input link to an output link at a router

Data Plane

•Network-wide logic •Determines how datagram is routed among routers along end to end path from source host to destination host

Control Plane

The __________ is the third layer in the OSI model of computer networks. Its main function is to transfer network packets from the source to the destination. It is involved both the source host and the destination host.

network Layer

Convert information into small packets

Fragmentation

Assembling of data

Defragmentation

The main responsibility of the ______ is to carry the data packets from the source to the destination without changing or using them.

Network layer

The process of encapsulating the data received from the upper layers of the network (also called ______) in a network layer packet at the source and decapsulating the payload from the network layer packet at the destination is known as _______

packetizing payload

___________ is simply defined as the action applied by each router when a packet arrives at one of its interfaces. Routers are used on the network for forwarding a packet from the local network to the remote network. pushing of data

Internet Protocol (IP):

is used to send error messages and other control information between devices on a network.

Internet Control Message Protocol (ICMP): ICMP

is used to map IP addresses to Media Access Control (MAC) addresses. MAC addresses are unique identifiers assigned to network devices.

Address Resolution Protocol (ARP):

Internet Protocol Address

addresses are the identifier that allows information to be sent between devices on a network: they contain location information and make devices accessible for communication.

IP Address

A ______ is a fixed address assigned to a device that remains constant. They are typically used for hosting websites or running servers. Static IP addresses are typically provided by the user’s ISP or network administrator, and typically come at an additional cost.

static IP address

A ________ refers to an address assigned to a device temporarily by an ISP. Dynamic IP addresses are typically assigned to devices such as computers, smartphones etc. They provide a level of anonymity and security as the IP address changes periodically
