Flow control and Error control are the control mechanism at data link layer and transport layer. Whenever the sends the data to the receiver these two mechanisms helps in proper delivering of the reliable data to the receiver. The main difference between the flow control and error control is that the flow control observes the proper flow of the data from sender to receiver, on the other hand, the error control observes that the data delivered to the receiver is error free and reliable. Let's … [Read more...]

Pure ALOHA and Slotted ALOHA both are the Random Access Protocols, that are implemented on the Medium Access Control (MAC) layer, a sublayer of Data Link Layer. The purpose of the ALOHA protocol is to determine that which competing station must get the next chance of accessing the multi-access channel at MAC layer. The main difference between Pure ALOHA and Slotted ALOHA is that the time in Pure Aloha is continuous whereas, the time in Slotted ALOHA is discrete. Let us discuss the other … [Read more...]

Bandwidth and frequency both are the measuring terms of networking. The basic difference between bandwidth and frequency is that bandwidth measures the amount of data transferred per second whereas the frequency measure the number of oscillation of the data signal per second. Let us study the comparison chart of the bandwidth and frequency. Content: Bandwidth Vs Frequency Comparison Chart Definition Key Differences Conclusion Comparison Chart Definition of … [Read more...]

ARP and RARP both are the Network layer protocol. Whenever a host needs to send an IP datagram to another host, the sender requires both the logical address and physical address of the receiver. The dynamic mapping provides two protocols ARP and RARP. The basic difference between ARP and RARP is that ARP when provided with the logical address of the receiver it obtains the physical address of the receiver whereas in RARP when provided with the physical address of the host, it obtains the … [Read more...]

FTP and TFTP both are the application layer protocols. Both are used to transfer a file from client to server or from the server to the client . But FTP is more complex than TFTP. There are many differences between FTP and TFTP, but the major difference between FTP and TFTP is that FTP establishes two connection for transferring a file between client and server that are TCP's port 20 for data connection and TCP's port 21 for the control connection. On the other hand, TFTP uses the only single … [Read more...]

In Computer Networks, the term unicast and multicast are the information transmission methods. In unicast, one station transfers the information to only one receiver station. In multicast, the sender transfers the information to a group of interested receiver stations. The fundamental difference between unicast and multicast is that unicast is one-to-one communication and multicast is a one-to-many communication process. Let us study in brief the difference between unicast and multicast … [Read more...]

Bridge and gateway, are the backbone devices of the networking. A "bridge" operates on two layers, a physical layer, and a data link layer. A "gateway" operates on all the seven layers of the OSI model. The primary difference between a bridge and a gateway is that a "bridge is used only to transfer the frame to the expected destination, in a most efficient path". A gateway "converts the format of the packet in one protocol to the format of the packet in another protocol". Let study, the … [Read more...]

"Go-Back-N Protocol and "Selective Repeat Protocol" are the sliding window protocols. The sliding window protocol is primarily an error control protocol, i.e. it is a method of error detection and error correction. The basic difference between go-back-n protocol and selective repeat protocol is that the "go-back-n protocol" retransmits all the frames that lie after the frame which is damaged or lost. The "selective repeat protocol" retransmits only that frame which is damaged or … [Read more...]

In the previous article, we have discussed Serial and Parallel Transmission. As we know in Serial Transmission data is sent bit by bit, in such a way that each bit follows another. It is of two types namely, Synchronous and Asynchronous Transmission. One of the major differences is that in Synchronous Transmission, the sender and receiver should have synchronized clocks before data transmission. Whereas Asynchronous Transmission does not require a clock, but it adds a parity bit to the data … [Read more...]

TCP and UDP are the transport layer protocols that are responsible to provide end-to-end communication. However, TCP is a connection-oriented protocol whereas, UDP is a connection-less protocol. Do you know why we require these protocols? Well, the layer 3 protocol that works on the IP is usually connectionless, unacknowledgeable and unreliable. Thus, these protocols don't provide the guaranteed delivery of data. So, there was a need for a protocol that would resolve the problems like … [Read more...]
