A router is a networking device that connects multiple networks and directs traffic between them. A switch is a networking device that connects devices within a network.

• A router operates at the network layer (Layer 3) of the OSI model, while a switch operates at the data link layer (Layer 2).

• Routers are used to connect different networks, such as connecting a home network to the internet, while switches are used to connect devices within a network, such as connecting computer...read more

DHCP (Dynamic Host Configuration Protocol) is a network protocol that automatically assigns IP addresses and other network configuration settings to devices.

• DHCP is used to manage and allocate IP addresses in a network.

• It allows devices to obtain IP addresses dynamically instead of manually configuring them.

• DHCP servers provide IP addresses, subnet masks, default gateways, and other network settings to clients.

• Leases are used to control the duration of IP address assignments....read more

There are no Leary in OSI.

• OSI (Open Systems Interconnection) is a conceptual model for communication between computers.

• It has seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• There is no mention of Leary in any of the OSI layers or in the model itself.

FQDN stands for Fully Qualified Domain Name, which is the complete domain name for a specific computer or server on the internet.

• FQDN includes the hostname and the domain name, separated by periods.

• It is used to uniquely identify a specific computer or server on the internet.

• Example: www.google.com is an FQDN.

• FQDN is used in DNS to translate domain names into IP addresses.

OSI model is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system.

• OSI stands for Open Systems Interconnection.

• It has 7 layers, each with a specific function.

• The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer communicates with the layer above and below it.

• Example: HTTP (Application layer) uses TCP (Transport layer) to establish a connection and trans...read more

HA, VRRP, BGP, VRF are networking protocols and technologies used for high availability, redundancy, routing, and virtualization.

• HA (High Availability) ensures continuous operation of network services by eliminating single points of failure.

• VRRP (Virtual Router Redundancy Protocol) allows multiple routers to work together in a group, providing backup in case of failure.

• BGP (Border Gateway Protocol) is used for routing between different autonomous systems on the internet.

• VRF (...read more

To fix a printer, first check the connections, restart the printer, update drivers, and check for paper jams.

• Check the connections - ensure the printer is properly connected to the power source and computer.

• Restart the printer - power off the printer, wait a few seconds, then power it back on.
