start bit signals receiver end to receive sequence of bits(data bits) and stop bit to signal the end of bit transmission.

An ARP query is sent in a broadcast frame because the querying host does not know

which adapter address corresponds to the IP address in question. For the response, the

sending node knows the adapter address to which the response should be sent, so

there is no need to send a broadcast frame (which would have to be processed by all

the other nodes on the LAN).

It is connected by a network cable, switch and a router.

Excessive broadcasts, and using hubs instead of switches or routers to segment the network.

to split the Internet between different computers or to make it wireless if it is a wireless router

There are 2^24 host in class A but (2^24)-2 hosts are valid since the first and last address are reserved .

The routers in the network are operating with consistent routing knowledge.

A transport layer is the backbone of TCP/IP and the Internet. In this day and age, there are not design flaws in the system. The design of transport layer incorporates data stream with transmission.

They are all good careers. You have to decide what you are interested in and what you are good at. Some may suit some people better than others. So different people will go into these different roles. There are needs for them, so whichever they go into, there will be jobs in them.

There is no need for the ICMPv4 message to travel outside of its own network because its only purpose is to inform the next router in the spanning tree of group member-ship.

How much the business is willing to pay them.

IP datagram can be used to describe a portion of IP data. Each IP datagram has set of fields arranged in an order. The order is specific which helps to decode and read the stream easily. IP datagram has fields like Version, header length, Type of service, Total length, checksum, flag, protocol, Time to live, Identification, source and destination ip address, padding, options and payload.

MTU:- Maximum Transmission Unit is the size of the largest packet that a communication protocol can pass. The size can be fixed by some standard or decided at the time of connection

Fragmentation is a process of breaking the IP packets into smaller pieces. Fragmentation is needed when the datagram is larger than the MTU. Each fragment becomes a datagram in itself and transmitted independently from source. When received by destination they are reassembled.

I would say a greedy protocol is one which tends to use more resources for its performance but does not provide good service for the high resource usage.

A proprietary network protocol is one that does not comply to any open standards. The intent of a proprietary protocol is to limit communication only to nodes that implement a specific application. NetBIOS is an example of a proprietary network protocol that is only applicable to Microsoft Windows hosts. The opposite of a proprietary protocol is an open standard, which can be utilized by any application. An example of an open standard is TCP/IP, the standard protocol of the Internet.

Yes. A mac address is assigned to a device at the factory and cannot be altered. In most cases, it is the IP address that is temporary and often changes.
