A device that can bridge multiple network structures is known as a gateway. Therefore gateways can connect two dissimilar LANs. The major difference between gateways and routers is that routers work at the OSI model’s network layer. In contrast, gateways work from the lowest to the topmost layer, i.e., the ... Read More

Let us understand what GSM is.GSMGSM represents Global Systems for Mobile Communications. It is the fundamental standard-bearer of 2G technologies. It is generally used in mobile communication. Short Messaging System (SMS) was introduced into GSM networks along with the capability to download content from multiple service providers. The content can ... Read More

Data Communication is a phase of swapping data or information. This process contains a communication system that is created from hardware and software. The hardware part contains the sender and receiver devices and the intermediate devices through which the data moves. The software element includes specific rules which determine what ... Read More

Antivirus software is a program that operates against virus protection. It can find or perceive the virus, and afterward, subsequent to discovering the nearness of the virus, it operates on expelling it from the computer system. Antivirus software operates as a prophylactic with the objective that it takes out a ... Read More

Hacking is the art of examining the private things that are being private from general usage and discovering loopholes in the security and facilitating them to benefit others. Hacking is the procedure of discovering vulnerabilities in a system and using these found vulnerabilities to boost unauthorized access into the system ... Read More

Simplified Data Encryption Standard (S-DES) is equivalent to the DES algorithm. The SDES encryption algorithm produces an 8-bit block of plaintext (example: 10111101) and a 10-bit key as input and makes an 8-bit block of ciphertext as output. The S-DES decryption algorithm takes an 8-bit block of ciphertext and the ... Read More

Cyber security can be defined as information technology (IT) security.Cyber Security is all about preserving your devices and network from unauthorized access or alteration. The internet is not only ... Read More

Let us begin by understanding what SNAT is.SNATSNAT represents Source NAT. Source NAT is used when an internal user starts a connection with an external Host. Therefore, the layer 3 device on which we already configured NAT, interprets the private IP address of the Host to Public IP. It can ... Read More

In Cloud Computing, Virtualization is creating a virtual platform of server operating framework and storage devices. This will support the client by supporting various machines simultaneously. It also enables sharing an individual physical example of a resource or an application to several clients.Cloud Virtualizations also handles the workload by changing ... Read More

Cluster computing defines several computers linked on a network and implemented like an individual entity. Each computer that is linked to the network is known as a node.Cluster computing provides solutions to solve difficult problems by providing faster computational speed, and enhanced data integrity. The connected computers implement operations all ... Read More
