WebOct 29, 2024 · 1. Broadcast : Broadcast transfer (one-to-all) techniques and can be classified into two types : Limited Broadcasting, Direct Broadcasting. In broadcasting mode, transmission happens from one host to all the other hosts connected on the LAN. The devices such as bridge uses this. WebLimited broadcasts are required for many protocols included in the IPv4 based TCP/IP protocol suite to function. Therefore, the limited broadcast messages should reach all the connected interfaces of all the devices in the broadcast domain. The router of the network also should receive the broadcast copy and should process the information in ...

The trap is answer (a) : 10.1.255.255/16 is a broadcast address, as is 10.1.255.255/24, but without mask information, we must assume classful addressing, and 10.1.255.255/8 is a unicast address. The hint is the word network in the question. WebMar 20, 2024 · What is IPv4? IPv4, or Internet Protocol version 4, was developed back in the early 1980s. And despite the invention of the more modern IPv6, IPv4 still routes most of the world’s traffic. IPv4 uses a 32-bit address and can support a maximum of 2 32 (or more than 4 billion) IP addresses.
WebNov 6, 2024 · In IPv4, there’re two kinds of addressing: classful and classless. Classful IP addressing is divided further into classes: A, B, C, D, and E. Moreover, we can perceive the class of an IP address using the first few bits in binary form notation. Furthermore, we can divide the IP addresses into classes based on the requirement.

In computer networking, broadcasting refers to transmitting a packet that will be received by every device on the network. In practice, the scope of the broadcast is limited to a broadcast domain. Broadcasting is the most general communication method and is also the most intensive, in the sense that many messages may be required and many network devices are involved. This is in contrast to unicast addressing in which a host sends datagrams to another single host, identified …
