What is Forward Error Correction?Forward Error Correction (FEC) is a way of getting error control in data transmission in which the source (transmitter) provides redundant data and the destination (receiver) recognizes only the portion of the data that is error-free. FEC can broadcast data to several destinations simultaneously from a single source because it does not require handshaking between the source and the destination.Each character is conveyed twice in the simplest form of FEC.The receiver verifies that both instances of each character follow the protocol in use.If both conformance cases occur, the character is accepted.If one instance of conformance occurs ...

DjVu is a computer file format created to hold scanned documents, particularly ones that include text, line drawings, indexed color pictures, and photographs. It uses various methods such as image layer separation of text and background/pictures, progressive loading, arithmetic coding, and lossy compression for bitonal (monochrome) images to compress the files.People who want to distribute high-resolution documents in the public domain need a lossy compression technique to deliver a high compression rate. These documents are usually read in a web browser. The compression technique employed should have a rapid decoding rate to allow displaying such a high-resolution document in a ... Read More

WiFi networks are getting more and more common. WiFi has applications in interior and outdoor localization, home automation, and physical analytics and provides network connectivity.SSID is short for Service Set Identifier, which is the name for a WiFi network in layman's terms. SSID is a name for the network that is used to identify a wireless network. But don't get confused. SSID is not the name that we assign to a wireless router though it may be the name shown to users. Instead, SSID is a different 32-Octet string that distinguishes any other nearby network name.SSID acts as a street ... Read More

Routers are critical networking equipment that control the data flow across a network. Routers have one or more input and output interfaces via which packets are received and sent.Since a router's memory is limited, it may be unable to handle newly incoming packets. This happens when the pace at which packets arrive exceeds the rate at which packets leave the router's memory. New packets are ignored in this circumstance, while older packets are discarded. Routers must implement some sort of queuing discipline as part of their resource allocation algorithms, in order to regulate how packets are stored or discarded as ... Read More

Layer 2 Forwarding (L2F) is a Cisco Systems-developed media-independent t technology. Virtual private networks (VPNs) can be formed over a public network like the Internet using Layer 2 Forwarding (L2F), which tunnels data-link layer packets in protocols like Point-to-Point Protocol (PPP) or Serial Line Internet Protocol (SLIP).L2F can be utilized on the server-side with capabilities like user authentication via Remote Authentication Dial-In User Service (RADIUS), dynamic address allocation, and quality of service (QoS). In addition, Cisco's Internetwork Operating System is used to implement L2F in routers (IOS).Since the tunnelling approach is not connected to an IP (Internet Protocol) network, it ... Read More

IPv6 is the latest version of the main communication method that identifies and places computers and other devices online. Provides efficient package management, which improves performance and security. Despite this, the entire Internet is taking its toll on switching from IPv4.IPv4 uses a 32-bit speech mode to support 4.3 billion devices, which was considered sufficient at the time. However, the rise of the Internet, personal computers, smartphones, and now the Internet of Things devices shows that the globe needs more addresses.The Internet Engineering Task Force (IETF) fortunately recognized this 20 years ago. It designed IPv6 in 1998, which employs 128-bit ... Read More

Wireless/Mobile computing is divided into three categories: Mobile communication, hardware, and software. Since most of us are familiar with hardware and software, we will concentrate on mobile communication.GSM (Global System of Mobile communication)GSM uses TDMA (Time Division Multiple Access) technologies that split the narrow band 30 kHz wide and 6.7 milliseconds long into three time slots.Traditional analog technologies can only contain as much data as we can carry in one-third of the three time slots. Another exciting feature introduced in GSM is that users can use SIM to identify themselves in the network and switch phones whenever needed.CDMA (Code Division ... Read More
