Registered Jack The Registered jack is a network interface to connect various data equipment and telecommunication systems to provide the services offered by the telephone exchange. The local channels then exchange data for the shorter or longer-distance carriers. It offers network cabling, fixing wires, and jack construction. Customers and telephone companies have to register through the registration interface to deliver and manage the physical installation of jacks and wires this was made mandatory in the year 1970 by Federal Communications Commission (FCC) and registered connections have brought to real-time usage in the year 1973 with the physical setup of wires, ...

Email communication has been possible only with the help of the SMTP protocol. It is used at the last layer of the OSI (Open Source Interconnection) model. The SMTP has two main parts SMTP client request and SMTP server response. The mode of communication between the client and server is established with the commands. The SMTP Response is sent with a 3-digit number along with the text messages and can be detected using the first digit of the SMTP response. Simple Mail Transfer Protocol (SMTP) SMTP is a type of Application layer protocol used to send and receive mail. It ... Read More

Google Cloud provides users with different resources and one among them is Database services. After exploring the database services from the websites, choosing the right for your concern is difficult as there are many options available. The primary purpose of these services is to store the data securely and globally. There are three types of services provided namely hybrid data distribution, regional data distribution, and multi-cloud distribution. In the below article based on the database, the services provided by them are explained. Google Cloud Database Services Deploying Database The Google Cloud database supports three main types of deployment that are ... Read More

Repeaters and bridges are both networking devices, both used to extend the range of a network, more specifically bridge provides the facility to combine various LANs (Local Area Networks) to develop a larger LAN. While repeaters are mainly used to amplify signal strength when the signal comes to the repeater it regenerates, which would be an amplified signal of the same and retransmits. Repeaters are commonly used in LANs to extend the range of a network more than the 100-meter limit of Ethernet. Bridge works at the Data Link Layer (DLL) of the model named OSI and they use MAC ...

In an IT field or any company, the computer systems are interconnected to the same server to share information among them. It follows distributed information systems, in which every computer is physically connected and connected to a common network. RPC stands for Remote Procedure Call which is a type of protocol used in the operating system for making communication over remote devices. Using the RPC message protocol, the message request is sent and after getting the reply the communication is established. Remote Procedure Call The TCP/IP or UDP comes under the low-level transport layer protocol for communication between the networks ... Read More

People are getting connected easily with others using the network for sharing data. The data is transmitted from the sender side to the client side either in a wired or wireless connection and the mode of medium will be guided or unguided. For the wired way of data transmission, the connections can be chosen from the coaxial cable, fiber optic cable, and twisted pair cable. Wireless Communication emerged in the 19th century and is used in every field of communication. Wireless Communication Data communication occurs in the unguided medium when the sender and receiver are not physically connected but use ... Read More

Filtering Filtering is the process of validating or screening, whether input data given by the user meets the standard format or not. Content filtering is the process of screening emails or web pages that are undesirable. These operate with predefined patterns that include user text string or image data. Recent versions of firewalls include filtering options as built-in features either as hardware or software support. Content filtering is used in cybersecurity as it can block malicious or hacked websites and also block social networking websites as per standard policies defined in corporate organizations. Filtering methods can be deployed in applications ... Read More

Pubic Wi-Fi is more dangerous in the early times and now it has included solutions to the risks of Wi-Fi. In the modern world, Wi-Fi is installed in every place to make people have easier access to the internet. Even though it provides the usage of the internet without any password, it is also possible that the devices that are connected to public Wi-Fi will face cyber attacks. Some examples of public Wi-Fi are set up in airports, Railway stations, Restaurants, and public libraries. Public Wi-Fi The websites have a separate encryption technique to prevent cyber attacks and so it ... Read More

In the world of cyberattacks, organizations should have a trustable source to make secured file transfers. For this IETF (Internet Engineering Task Force) developed a protocol named the Secured File Transfer Protocol along with the secure shell to have the strongest protection against hackers. Using this protocol, we can avoid the Man-in-the-attack which is the most vulnerable attack faced during file transfer on the internet. The transferred file is authenticated and a secured shell is provided so the hacker cannot see the password, thus reducing the threats. Secure File Transfer Protocol SFTP comes under the network layer of the OSI ... Read More

BSS and ESS are terms used in wireless networking to describe different types of wireless networks and their functions. A BSS is a wireless network made up of a group of devices within range of an access point and its AP, while an ESS is a network made up of multiple BSSs connected through a distributed system. Key differences between BSS and ESS include coverage, scalability, roaming, and definition. BSS has limited coverage, scalability, and roaming, while ESS provides better scalability, coverage, and roaming capabilities. Understanding these differences is important in choosing the right wireless network for your particular application. ... Read More
