Difference between Ethernet and LAN
A LAN is a computer network that is limited to a particular geographic area. Ethernet, on the other hand, is a LAN network standard used in wired LAN. Go through this article to find out more about the features of Ethernet and LAN and how they are different from each other. What is Ethernet? Ethernet is a widely used LAN standard that defines networking technologies and systems used in local area networks (LANs) to connect computers inside a single physical space. It is defined under IEEE 802.3 standards and is part of the Physical and Data Link layers ...
Read MoreJoint Photographic Experts Group (JPEG)
JPEG (Joint Photographic Experts Group) is a standardized image compression technique commonly used for digital photographs. Developed by the Joint Photographic Experts Group in the early 1990s, JPEG is designed to reduce file sizes of digital images while maintaining reasonable image quality through lossy compression. JPEG uses a lossy compression algorithm, meaning some data is permanently lost during compression. The compression level can be adjusted − higher compression yields smaller files but lower quality, while lower compression maintains better quality at the cost of larger file sizes. This flexibility makes JPEG ideal for web usage and digital photography. ...
Read MoreTraditional Wireless Mobile Communication
The cellular device has evolved significantly and become an integral part of everyone's life as a portable communication device. Most people now have access to mobile technology that uses the Global System for Mobile Communication (GSM), which represents traditional wireless mobile communication. The first mobile phones used radio waves for communication, with cellular technology comprising cells and base stations that divide coverage areas into smaller cells for frequency reuse. The traditional analog system was designed to transmit voice signals in analog form rather than digital format. The Motorola DynaTAC 8000X, introduced commercially in the 1980s, was the first wireless ...
Read MoreRole of Subnet Mask
A subnet mask is a 32-bit address that separates the network and host portions of an IP address. It plays a crucial role in subnetting, which divides large networks into smaller, more manageable segments to reduce network traffic and improve performance. The subnet mask uses binary notation with network bits set to 1 and host bits set to 0. This allows routers and network devices to determine which part of an IP address represents the network and which part represents the host device within that network. Subnet Mask Operation ...
Read MoreMaster TCL Scripting: Discover How to Sum Up n Natural Numbers with Looping Statements
TCL (Tool Command Language) scripting is a powerful scripting language commonly used for automating network device configuration and management tasks. In networking environments, TCL scripts help automate repetitive operations such as configuring interfaces, monitoring performance, and generating reports on routers and switches. One fundamental programming concept that demonstrates TCL's versatility is calculating the sum of n natural numbers using looping statements. This mathematical operation forms the foundation for many network automation calculations and serves as an excellent introduction to TCL scripting techniques. Algorithm for Summing Natural Numbers To calculate the sum of n natural numbers using TCL ...
Read MoreDifferentiate between GSM and CDMA in Computer Network.
In mobile telecommunications, two major digital cellular technologies have dominated the market: GSM (Global System for Mobile Communication) and CDMA (Code Division Multiple Access). Both technologies enable mobile communication but use fundamentally different approaches for handling multiple users on the same network infrastructure. Understanding the differences between GSM and CDMA is crucial for network engineers and telecommunications professionals, as each technology offers distinct advantages in terms of security, flexibility, and network capacity. GSM (Global System for Mobile Communication) GSM is a digital mobile communication standard that operates as a second-generation (2G) cellular technology. It uses Time Division ...
Read MoreFrame bursting in Computer Network
Frame bursting is a transmission technique used at the data link layer of the OSI model to increase the rate of transmission of data frames. It can be effectively deployed in Gigabit Ethernet networks to increase network throughput and is specified in the IEEE 802.11e QoS specification. By this technique, a sender can transmit a series of frames in succession without surrendering control of the transmission medium. A set of smaller frames may be concatenated to form a large frame that is transmitted at one go, reducing overhead and improving efficiency. How Frame Bursting Works Standard Transmission ...
Read MoreDifference between Fast Ethernet and Gigabit Ethernet
Ethernet is a set of protocols that are used primarily in LANs, although they can also be used in larger networks like MANs and even WANs. Ethernet was first standardized in the 1980s as the IEEE 802.3 standard. Since then, it has seen several upgrades and its data carrying capacity kept increasing with each upgrade. Standard Ethernet can support data speeds up to 10 Mbps. Fast Ethernet can carry data at a maximum speed of 100 Mbps. Gigabit Ethernet data speeds reached a maximum speed of 1 Gbps. 10-Gigabit Ethernet can ...
Read MoreMotion Picture Experts Group (MPEG)
Motion Picture Experts Group (MPEG) is a family of international standards for audio and video compression and transmission, developed by a working group of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). MPEG standards enable efficient storage and transmission of multimedia content by significantly reducing file sizes while maintaining acceptable quality. MPEG uses lossy compression, meaning some data is discarded during the compression process to achieve smaller file sizes. The compression level can be adjusted to balance between file size and quality based on specific requirements. MPEG Compression Process ...
Read MoreUniversal Plug and Play (UPnP)
Universal Plug and Play (UPnP) is a networking protocol that enables automatic device discovery and connectivity within local area networks. It uses standard protocols like TCP/IP, DHCP, and HTTP to establish connections and acquire IP addresses for wirelessly connected devices. UPnP simplifies device interactions by allowing automatic configuration without manual setup. Common examples include streaming video from laptops to smart TVs, connecting printers to multiple devices, and enabling home automation through IoT devices. UPnP Device Discovery and Connection Laptop 192.168.1.100 ...
