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 lost. Content: … [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 type 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 before … [Read more...]

There exist some similarities and dissimilarities between the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). One of the differences is that TCP is a connection-oriented protocol as it establishes an end to end connection between computers before transferring the data. On the other hand, UDP is a connection-less protocol since it does not determine the connection before sending data. The similarity between them is that both TCP and UDP is present in the Transport Layer of … [Read more...]

For transferring data between computers, laptops two methods are used, namely, Serial Transmission and Parallel Transmission. There are some similarities and dissimilarities between them. One of the primary difference is that; in Serial Transmission data is sent bit by bit whereas, in Parallel Transmission a byte (8 bits) or character is sent. And the Similarity is that both are used to connect and communicate with peripheral devices. Other differences are discussed below. Content: Serial Vs … [Read more...]

Most of us get confused between the terms Internet and Intranet. Although there exist a lot of disparity between them, one of the differences is that the Internet is open to all and can be accessed by everyone whereas, Intranet requires authenticated login as an organization privately owns it.

The "Antivirus" and "Internet Security" are the software that protects the user from malicious programs by blocking and removing them. There are some similarities and dissimilarities between them. One of the major differences is that Antivirus protects the computer from viruses whereas, Internet Security provides protection from spyware, viruses, phishing, spam, and email attachments. Content: Antivirus Vs Internet Security Comparison Chart Definition Key … [Read more...]

Virus and Worms are the malicious programs, which enters our computers through CD's, Pen drives, email attachments and the files we download from the Internet. Both have some similarities and dissimilarities between them. One of the major differences is that Worms do not require any human action to replicate while Viruses replicates as soon as the user runs the infected file. Content: Virus Vs Worms Comparison Chart Definition Key Differences Conclusion Comparison … [Read more...]

The Network allows computers to connect and communicate with different computers via any medium. LAN, MAN, and WAN are the three types of the network designed to operate over the area they cover. There are some similarities and dissimilarities between them. One of the major differences is the geographical area they cover, i.e. LAN covers the smallest area; MAN  covers an area larger than LAN and WAN comprises the largest of all. Content: LAN Vs MAN Vs WAN Comparison Chart Definition Key … [Read more...]

TCP/IP and OSI are the two most widely used networking models for communication. There are some similarities and dissimilarities between them. One of the major difference is that OSI is a conceptual model which is not practically used for communication, whereas, TCP/IP is used for establishing a connection and communicating through the network. Other differences are discussed below. Content: TCP/IP Vs OSI Model Comparison Chart Diagram Definition Key Differences … [Read more...]
