MAC - Media Access Control, address is a globally unique identifier assigned to network devices, and therefore it is often referred to as hardware or physical address.

Management Information Base is part of every SNMP-managed device. Each SNMP agent has the MIB database that contains information about the device's status, its performance, connections, and configuration. The MIB is queried by SNMP.

It provides a framework for discussing network operations and design

The IP address of a packet is normally analyzed by Router.

FTP-File Transfer Protocol

NO.It is Transmission Controll Block

Hubs regenerate electrical signals, which are specified at the Physical layer.

The network layer concerns with the packets. It brings the packets from the source to the destination.

MAU is Multistation Access Unit

IPv6 - Internet Protocol Version 6.

The speed of the transmission data is generally determined by the cables or connectors we use for data transmission. In networking, layer-1 the physical is which deals with the network cables like pins, usb, connectors, etc... we use for data transmission.

The logical arrangement of the nodes of different networks to communicate is called as topology.

Telnet uses TCP at layer 4. It uses IP at layer 3. We know that Telnet uses TCP/IP protocol, but in the question, it is asked specifically at layer 4 what is used in Telnet. So it is TCP at layer4 and IP at layer 3.

Ethernet uses Bus topology.

Fiber-optic physical or wired connection is the fastest communication connection.

Application layer protocol defines types of messages exchanged, message format, syntax and semantics and rules for when and how processes send and respond to messages.

Frame relay is a packet switching technology. It will operate in the data link layer.

It is a protocol formerly used to exchange routing information between Internet core routers.

It is a simple protocol used to exchange information between the routers.
