The 802.16 MAC Sublayer Protocol
The IEEE 802.16 is a set of standards defining the specifications for wireless broadband technology. It has been commercialized as Worldwide Interoperability for Microwave Access (WiMAX) that is responsible for the delivery of last-mile wireless broadband access. It lays down the standards for both physical layer as well as medium access control (MAC) layer for WiMAX. The IEEE 802.16 MAC sublayer is a part of the data link layer. The data link layer of WiMAX is divided into three sublayers as follows − Security sublayer − This is the bottommost layer and is concerned with the ...
Read MoreAlgorithm for Dynamic Time out timer Calculation
A dynamic timeout timer is a sophisticated timing mechanism that automatically adjusts its timeout value based on current system conditions, unlike static timers with fixed values. This adaptive approach is crucial in network communications where conditions like congestion, load, and data size vary constantly. Dynamic timeout timers are essential for reliable network protocols, particularly in TCP retransmission timeout (RTO) calculations, where they help maintain optimal performance across varying network conditions. How Dynamic Timeout Works The dynamic timeout algorithm continuously monitors system parameters and adjusts the timeout value accordingly. The core principle is to balance between being too ...
Read MoreWhat is Touchless Touchscreen Technology?
A touchscreen is an essential input/output device layered on top of a computer display. Users provide input through single or multi-touch gestures by touching the screen, allowing direct interaction with displayed content without intermediate devices. Traditional touchscreens use resistive or capacitive technologies. Resistive systems include two electrically conductive layers separated by spacers. When the screen is touched, these layers connect, changing the electrical current flow, which the software interprets as coordinates and executes corresponding functions. Touchless touchscreen technology is a subset of gesture control technology that enables interaction between computers and users without physical contact. It relies on ...
Read MoreConnectionless Services
A Connectionless service is a data communication method between two nodes where the sender transmits data without establishing a dedicated connection or ensuring the receiver's availability. In this model, each data packet contains complete destination addressing information and is routed independently of other packets through the network. Unlike connection-oriented services, connectionless communication requires no initial handshake or connection setup. Data packets, called datagrams, may take different paths to reach their destination, with the network making routing decisions independently for each packet. Connectionless Service - Independent Packet Routing Sender ...
Read MoreAll you need to know about Network Neutrality
Network Neutrality, also known as net neutrality, is the principle that all internet traffic should be treated equally, without discrimination or preference given to any particular type of data or service. This principle is based on the idea that the internet should be a level playing field, where all users have equal access to the same information and opportunities. Network Neutrality Core Principles No Blocking ISPs cannot block legal content No Throttling ISPs cannot slow specific services ...
Read MoreHow to hide an IP address
An IP address is like a digital fingerprint, revealing your location and identity online. Just as you can use a disguise to hide your physical identity, you can also conceal your IP address to protect your privacy and security. Here are several effective methods to hide your IP address: Methods to Hide Your IP Address Virtual Private Network (VPN) A VPN creates a secure, encrypted tunnel for all your online activity and assigns you a new IP address from a different location. This makes it appear as though you are browsing from somewhere else entirely. ...
Read MoreWhat are the types of Transfer Modes in HDLC?
HDLC (High-Level Data Link Control) is a bit-oriented protocol used for communication over point-to-point and multipoint connections. This protocol implements the structure of ARQ (Automatic Repeat Request) for reliable data transmission. The HDLC protocol is standardized by ISO and is designed for high-speed communication of large amounts of data. It was developed based on IBM's SDLC (Synchronous Data Link Control) protocol and can transmit data as bit strings of any required length. The basic unit of data communication in HDLC is called a frame. A transfer mode in HDLC defines the relationship between two devices in a network ...
Read MoreReference Models in Computer Network
In computer networks, reference models provide a conceptual framework that standardizes communication between heterogeneous networks. These models define how data should flow through different layers of network architecture, ensuring interoperability between different systems and technologies. The two most widely adopted reference models are: OSI Model − A theoretical seven-layer model TCP/IP Protocol Suite − A practical four-layer model used on the Internet OSI Model The OSI (Open System Interconnection) model was developed by the International Standards Organization (ISO). It provides a layered networking framework that conceptualizes how communication should occur between heterogeneous systems through ...
Read MorePublic-Key Signatures
A public key signature is a cryptographic method that uses asymmetric key pairs to authenticate digital messages and ensure their integrity. This system employs two mathematically related keys: a private key kept secret by the signer and a public key shared openly for verification purposes. Public key signatures operate on the principle that a message signed with a private key can only be verified using the corresponding public key. This creates a secure authentication mechanism where recipients can confirm both the sender's identity and that the message hasn't been altered during transmission. How Public Key Signatures Work ...
Read MoreWhat is the difference between Google and Microsoft?
Google and Microsoft are two technology giants that dominate different aspects of the digital landscape. Understanding their core differences helps clarify their unique roles in modern computing and internet services. Google Google is primarily an internet services company founded in 1998, specializing in search engines, online advertising, and cloud-based applications. Its core business model revolves around data collection and targeted advertising. Google's main products include the Google Search engine, Gmail, Google Drive, YouTube, and the Android operating system. Google Chrome, launched in 2008, has become the world's most popular web browser, supporting multiple platforms including Windows, macOS, ...
