Go-Back-N Protocol Vs Selective Repeat Protocol

Image
“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 repea t protocol” retransmits only that frame which is damaged or lost. Key Differences Between Go-Back-N and Selective Repeat Go-Back-N protocol is design to retransmit all the frames that are arrived after the damaged or a lost frame. On the other hand, Selective Repeat protocol retransmits only that frame that is damaged or lost. If the error rate is high i.e. more frames are being damaged and then retransmitting all the frames that arrived after a damaged frame waste the lots of bandwidth. On the other hand, selective repeat protocol re-transmits only damaged fra...

Internal Fragmentation Vs External Fragmentation

Whenever a process is loaded or removed from the physical memory block, it creates a small hole in memory space which is called fragment. Due to fragmentation, the system fails in allocating the contiguous memory space to a process even though it have the requested amount of memory but, in a non-contiguous manner. The fragmentation is further classified into two categories Internal and External Fragmentation. Key Differences Between Internal and External fragmentation The basic reason behind the occurrences of internal and external fragmentation is that internal fragmentation occurs when memory is partitioned into  fixed-sized blocks  whereas external fragmentation occurs when memory is partitioned into  variable size blocks . When the memory block allotted to the process comes out to be slightly larger than requested memory, then the free space left in the allotted memory block causes internal fragmentation. On the other hands, when the process is removed from the ...

Frame vs Packet

Image
Difference Between Frame and Packet     The crucial difference between frame and packet is that frame is the serial collection of bits, and it encapsulates packets whereas packets are the fragmented form of data and it encapsulates segment. Data link layer performs framing process. On the other hand, Network layer performs fragmentation of the data and create smaller chunks known as packets. Another major difference is that a frame includes device’s MAC address while a packet includes device’s IP address. Basis for comparison Frame Packet Basic Frame is the data link layer protocol data unit. Packet is the network layer protocol data unit. Associated OSI layer Data link layer Network layer Includes Source and destination MAC address. Source and destination IP address. Correlation Segment is encapsulated within a packet. Packet is encapsulated within a frame. Conclusion: Frames and Packets function as protocol data units utilize...
