Tech Differences

Substitution technique and transposition technique are the fundamental methods of codifying the plaintext message to acquire the respective ciphertext. These two methods are the basic building blocks of the encryption techniques and can also be used together, which is called a product cipher. The essential difference between the substitution technique and transpositional technique is that the substitution technique substitutes the letters of the plaintext from other letters, number and … [Read more...]

Network security has become a crucial part of the modern communication system. The need for network security was arisen to sustain the confidentiality and integrity of the data and guard it against the unauthorised access. The steganography and cryptography are the two sides of a coin where the steganography hides the traces of communication while cryptography uses encryption to make the message incomprehensible. The steganography does not employ changes in the structure of the message. On … [Read more...]

Jitter and latency are the characteristics attributed to the flow in the application layer. The jitter and latency are used as the metrics to measure the performance of the network. The main difference between the jitter and latency lies within their definition where latency is nothing but a delay through the network whereas the jitter is variation in the amount of the latency. The increase in latency and jitter have the adverse effect on the network performance, so it is essential to monitor … [Read more...]

The cloud computing works in a consolidated manner, and the big data comes under the cloud computing. The crucial difference between cloud computing and big data is that cloud computing is used to handle the huge storage capacity, (big data) through extending the computing and storage resources. On the other side, big data is nothing but an enormous amount of the unstructured, redundant and noisy data and information from which the useful knowledge have to be extracted. To perform the above … [Read more...]

Both the Firewall and the Proxy server reside between the network and the local computer which provides the security against the network threats. The firewall and proxy server works in conjunction. Firewall functions at a lower level and can filter all types of IP packets while the proxy server deals with the application level traffic and filter the requests coming from the unknown client. A proxy server can be considered as a part of the firewall. A firewall basically prevents the access of … [Read more...]
