Fibre Channel Protocol
Fibre Channel Protocol (FCP) is a communication protocol designed to provide fast and dependable data transfers between servers and storage devices in storage area networks (SANs). History of FCP FCP was first introduced in the early 1990s as a outcome of a deal between the tech giants among IBM, HP, and Sun Microsystems. The protocol was designed to improve upon the limitations of previous communication protocols used in SANs, such as SCSI, and to enable higher-speed data transfers. How FCP Works As mentioned, FCP is a layered protocol that operates at the transport and session layers of the OSI model. ...
Read MoreNetwork Hubs
A network hub is a common networking device that allows multiple devices to communicate with each other. Hubs are used in local area networks (LANs) to connect devices together, such as computers, printers, and servers. This article will explore the basics of network hubs, including how they work, the different types of hubs available, their advantages and disadvantages, their challenges and advancements. What is a Network Hub? A network hub is a central connection point for multiple devices in a LAN. It operates at the physical layer of the OSI model, which is responsible for transmitting data across a network. ...
Read MoreDigital Audio Broadcasting (DAB)
Radio broadcasting has come a long way since its inception over a century ago. From analog to digital, radio broadcasting has evolved to provide listeners with high-quality audio that can be received on a variety of devices. One of the latest advances in radio broadcasting is Digital Audio Broadcasting (DAB), a technology that is changing the way we listen to radio. What is DAB? DAB is a digital radio broadcasting system that uses digital audio compression to transmit audio signals over the airwaves. Unlike traditional analog radio, DAB offers higher quality audio and a wider range of features, such as ...
Read More2-tier and 3-tier Architecture in Networking
Architecture in networking refers to the way a network is designed and organized, serving as the blueprint for the interaction and cooperation between different components and systems. Effective network architecture is crucial for a successful network setup and requires careful planning and design. When it comes to classifying network architecture, a common division is single-tier, two-tier, or three-tier. In a two-tier architecture, the network is separated into a client tier where the end-user interacts with the system, and a server tier where applications, data, and processing power reside. This clear separation of responsibilities makes the network easier to manage, secure, ...
Read MoreHow to hide an IP address
An IP address is like a digital fingerprint, revealing your location and identity online. But just like how you can put on a disguise to hide your physical identity, you can also conceal your IP address to protect your privacy and security. Here are a few methods to do so − I. Using a Virtual Private Network (VPN) Think of a VPN as a cloak of invisibility for your internet browsing. It creates a secure tunnel for all your online activity, and assigns you a new IP address from a different location, making it appear as though you are somewhere ...
Read MoreCable TV for Data Transfer
Cable television (TV) networks have been used for data transfer in the past. Cable TV networks were initially designed to transmit television signals, but they have also been used to provide internet access and other types of data transfer services. This is typically done using a technology called "cable modem, " which allows data to be sent over the same cable that is used to transmit TV signals. Cable TV companies often provide internet service through cable modems as part of a bundle that includes TV and telephone services. Cable modem internet service is generally faster than DSL and has ...
Read MoreCable TV Networks
Cable television networks are television channels that are delivered to viewers through cable television systems, as opposed to broadcast television, satellite television, or the internet. Some examples of popular cable TV networks in the United States include ESPN, TNT, and HBO. Cable networks can also be divided into categories, such as news networks (CNN, Fox News), sports networks (ESPN, NBC Sports), movie networks (HBO, Showtime), and lifestyle networks (Food Network, HGTV). Cable Network operate by subscription where viewer pays to the operator to get access to the channels. Types of Cable TV Networks There are several different types of cable ...
Read MoreBerkeley's Algorithm
Berkeley's Algorithm is a distributed algorithm for computing the correct time in a network of computers. The algorithm is designed to work in a network where clocks may be running at slightly different rates, and some computers may experience intermittent communication failures. The basic idea behind Berkeley's Algorithm is that each computer in the network periodically sends its local time to a designated "master" computer, which then computes the correct time for the network based on the received timestamps. The master computer then sends the correct time back to all the computers in the network, and each computer sets its ...
Read MoreBinary Synchronous Communication (BISYNC)
Binary Synchronous Communication (BISYNC) is a communication protocol that uses synchronous transmission to transfer data between devices. In BISYNC, data is transmitted in fixed-length blocks, called frames, with a start and stop bit at the beginning and end of each frame. The start and stop bits are used to synchronize the sender and receiver, so that they can accurately read and interpret the data in the frame. BISYNC uses a complex set of control characters to manage the flow of data and to maintain the synchronization between the sender and receiver. For example, the "ENQ" (enquiry) character is used to ...
Read MoreBirman Schiper Stephenson Protocol
The Birman-Schiper-Stephenson (BSS) Protocol is a distributed computing protocol that allows a group of computers to maintain a consistent shared state despite the possibility of failures. It was first described in a paper by Michael Birman, Roger Schiper, and Tom Stephenson in 1985. In the BSS Protocol, each computer in the group is assigned a unique identifier and acts as a "replica" of the shared state. The replicas communicate with each other using a series of message passing operations to maintain consistency of the shared state. The protocol is based on a "token" that is passed between replicas, which serves ...
