The computers and other electronic devices transmit the data from one to another device in the form of signals and using a transmission media. The transmission media can be fundamentally categorised into two types guided and unguided. Unguided media is a wireless communication which carries electromagnetic waves by making use of air as a medium and also in the vacuum, it can transmit data and without requiring a physical conductor. Guided media need a physical medium to transmit signals such … [Read more...]

Repeater and Amplifier both are electronic devices used for enhancing the power of the transmitted signal. The prior difference between them is that repeater is used as a regenerator of the signal which also eliminates the noise from the signal. On the other hand, amplifier just enhances the amplitude of the signal waveform and does not care about the noise that is being amplified along with the signal.

The difference between Static and Dynamic IP address lies within the duration of assigned IP address. The static IP address is fixed IP address which is manually assigned to a device for a long period of time. On the other hand, the Dynamic IP address frequently changes whenever user boots his/her machine, and it is automatically assigned. An Internet Protocol (IP) address is a unique numerical identifier assigned to each device on a network to identify each connection uniquely. It encodes … [Read more...]

Telnet and FTP are the TCP/IP, application layer, connection-oriented protocols which establishes a connection to the server from the remote host to remotely log in to a system or transfer a file. These protocols can be used in a collaborated way, to transparently log in to the FTP server and then can be used to transfer files. The common difference between Telnet and FTP is that Telnet permits a client user to login to remote server to access its resources while FTP is used to transfer a … [Read more...]

Routing algorithms in the context of networking can be classified variously. The prior classification is based on the building and modification of a routing table. This can be done in two manners statically or dynamically. More precisely these are known as static and dynamic routing respectively. In the Static routing, the table is set up and modified manually whereas in the Dynamic routing the table is built automatically with the help of the routing protocols. Dynamic routing is preferred … [Read more...]

Network Address Translation (NAT) and Port Address Translation (PAT) are the protocols used to map the unregistered private (inside local) address of an internal network to a registered public (inside global) address of an external network before transferring the packet. The main difference between them is that NAT is used to map public IP addresses to private IP addresses, it could be a one-to-one or many-to-one relation. On the other hand, PAT is a type of NAT where the multiple private IP … [Read more...]

The terms confusion and diffusion are the properties for making a secure cipher. Both Confusion and diffusion are used to prevent the encryption key from its deduction or ultimately for preventing the original message. Confusion is used for creating clueless ciphertext while diffusion is used for increasing the redundancy of the plaintext over the major part of the ciphertext to make it obscure. The stream cipher only relies on confusion. Alternatively, diffusion is used by both stream and block … [Read more...]

The major difference between active and passive attacks is that in active attacks the attacker intercepts the connection and modifies the information. Whereas, in a passive attack, the attacker intercepts the transit information with the intention of reading and analyzing the information not for altering it. There are various types of threats, attacks and vulnerabilities present to corrupt and breach the system security. Security attacks are the computer attacks that compromise the security … [Read more...]

The authentication and authorization are used in respect of information security which enables the security on an automated information system. The terminologies are interchangeably used but are distinct. The identity of a person is assured by authentication. On the other hand, authorization checks the access list that the authenticated person has. In other words, the authorization includes the permissions that a person has given. Content: Authentication Vs Authorization Comparison Chart … [Read more...]

DNS and DHCP both work on the client-server architecture but are dissimilar terms. DNS maps the domain name to IP address whereas DHCP is a protocol which assigns IP to the hosts in a network be it statically or dynamically. DHCP is also used while setting up the DNS server to the host. Content: DNS Vs DHCP Comparison Chart Definition Key Differences Conclusion Comparison Chart Definition of DNS DNS (Domain Name System) is a mechanism which provides directory lookup … [Read more...]
