Network addresses are the addresses used in packets. Each network address has a network port, which identifies a particular data link, and a host or node part, which identifies a specific device on the data link identified by the network part.
Ans: Routing is a process of finding a path to transfer data from source to destination.
VLAN facilitates you to create a collision domain by groups other than just physical location while conventional LAN domains are always tied to a physical location.
Following are the main advantages of LAN switching:
1. It allows full-duplex data transmission and reception.
2. Media rate adaption.
3. Easy and efficient migration.
Public IP is used across the internet while private IP is used within the local LAN.
Unicast: It specifies one to one communication.
Multicast: It specifies one to group communication.
Broadcast: It specifies one to all communication.
Multicast: It specifies one to the nearest communication.
Static IP addresses are reserved and they don't change over time while dynamic IP addresses can be changed each time you connect to the internet.
Static IP addresses are given manually while dynamic IP addresses are provided by the DHCP server.

VLAN stands for Virtual Local Area Network.
Communication is a process of sending and receiving data by an externally connected data cable whereas transmission is a process of sending data from source to destination.
Data link layer is the second layer of the OSI model.
In full-duplex, communication occurs from both sides, while in half-duplex communication occurs in one direction.
Frame relay work at the Data link layer OSI model
When the topology enables the computers on the network only to simply listen and receive the signals, it is known as passive topology because they don't amplify the signals anyway.
No, you cannot assign IP addresses on layer 2.
These are the three possible ways of data transmission:
Open Shortest Path First
RIP depends on the number of hops to determine the best route to the network while, IGRP considers many factors before decides the best route to take i.e. bandwidth, reliability, MTU and hops count.
BootP is a short form of the Boot Program. It is a protocol that is used to boot diskless workstations connected to the network. BootP is also used by diskless workstations to determine its own IP address and also the IP addresses of server PC.
Latency is the amount of time delay. It is measured as the time difference between the point of time when a network receives the data and the time it is sent by another network.
PoE is said to be Power over Ethernet. It is used to pass an electric signal with data at a time.
MAC address stands for Media Access Control address. This is an address of a device that is identified as the Media Access Control Layer in the network architecture. The MAC address is unique and usually stored in ROM.
ARP stands for Address Resolution Protocol. ARP is a protocol that is used to map an IP address to a physical machine address.
RAPR stands for Reverse Address Resolution Protocol. RARP is a protocol that is used to map a MAC address to an IP address.

A stub area is an area that does not accept routing updates from outside its autonomous system.
The three sources of signal degradation on a data link are attenuation, interference, and distortion. Attenuation is a function of the resistance of the medium. Interference is a function of noise entering the medium. Distortion is a function of the reactive characteristics of the medium, which react differently to different frequency components of the signal.
PING stands for Packet Internet Groper. It is a computer network tool that is used to test whether a particular host is reachable across an IP address or not.
There are five types of passwords that can be set on a Cisco router:
HSRP is Cisco’s proprietary
Authentication, authorization, and accounting
It should include the subnet mask of each destination address.
