Difference Between Pure ALOHA and Slotted ALOHA

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...]

Difference Between Bandwidth and Frequency

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.

Difference Between ARP and RARP

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...]

Difference Between FTP and TFTP

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...]

Interface and Abstract class both contribute to "incomplete type" in OOP. Sometimes we need a superclass to define "what to do" but, not "how to do", it's how to do part will be implemented by the derived class according to its need, "interface" provide a solution to this. Sometimes we need a superclass class that defines some generalised structure that can be implemented by derived classes and some specified structure that can be utilised by the derived classes, "abstract class" provides a … [Read more...]
