Address resolution Protocol (ARP) Advanced Computer Network by Ravinder Nath Rajotiya - October 13, 20210 Address Resolution Protocol Address Resolution Protocol (ARP) is a communication protocol used to find the MAC (Media Access Control) address of a device from its IP address. This protocol is used when a device wants to communicate with another device on a Local Area Network or Ethernet. Types of ARP There are four types of Address Resolution Protocol, which is given below: Proxy ARP Gratuitous ARP Reverse ARP (RARP) Inverse ARP Click the link to view the PPT Address Resolution Protocol
Introduction to data Link Layer Advanced Computer Network by Ravinder Nath Rajotiya - September 25, 2021September 28, 20210 Data Link Layer Communication at DLL is node-to-node (two end host and the routers as nodes). Links-Cable, air. Two types Broadcast and point-to-point. In broadcast link is shared and in point-to-point the link is dedicated between two ends Services: Located between physical and network layer – When packet is travelling in the internet, DLL of a node(host or router) is responsible for delivering a datagram to the next node in the path. Framing – link addres(dst and src) IP add(src, dst) data, CRC Flow Control Error Control Congestion control Although the TCP/IP reference model is primarily supported as the standard model based on TCP/IP protocol suite, the focus of the TCP/IP reference model does not clearly separate and distinguish
Introduction to Physical Layer Advanced Computer Network by Ravinder Nath Rajotiya - September 25, 2021September 28, 20210 Role of Physical Layer Physical Layer Signals – bit Bite Rate- no. of bits sent in one seconds Bit length- distance one bit occupies on the transmission medium = propagation speed x bit duration Attenuation- Loss of energy as it travels on the medium. To compensate for loss, we may use different components such as amplifiers, Decible- It is the unit that measure the relative strength (power or voltage) of two signals one signal at two different points. db = 10 log10(P2/P1) or db = 20 log10 (V2/V1) It should be noted that db will be +ve if signal is amplified and –ve if signal is lost/attenuated Nyquist bit rate :For noiseless channel, the nyquist bit rate define theoretical maximum bit rate as Nyquist bit
