Network devices, or networking hardware, are physical devices that are required for communication and interaction between hardware on a computer network. Hubs connect multiple computer networking devices together. A hub also acts as a repeater in that it amplifies signals that deteriorate after traveling long distances over connecting cables.

By: Tracy V. Once, home networks were primarily the realm of technophiles -- most families either didn't need or couldn't afford more than one computer. But now, in addition to using computers for e-mail , people use them for schoolwork, shopping, instant messaging , downloading music and videos, and playing games. For many families, one computer is no longer enough to go around.

How Home Networking Works

Switches , routers , and wireless access points are the essential networking basics. Through them, devices connected to your network can communicate with one another and with other networks, like the Internet. Switches, routers, and wireless access points perform very different functions in a network. Switches are the foundation of most business networks. A switch acts as a controller, connecting computers, printers, and servers to a network in a building or a campus. Switches allow devices on your network to communicate with each other, as well as with other networks, creating a network of shared resources. Through information sharing and resource allocation, switches save money and increase productivity.

Top Tip: Security in a home wireless network? As is common for most home networking with in-house coaxial cable wiring, the transmission path between any TV connection points covers an output port-to-output port connection of a splitter. Preston Gralla provides step-by-step instructions to guard against bad guys trying to hack in to your home or office Wi-Fi network. Wireless Networking - an overview ScienceDirect Topics. Wired Network Edge vs. Wireless Edge PCWorld.

In computer networks, networked computing devices exchange data with each other using a data link. The best-known computer network is the Internet. Network computer devices that originate, route and terminate the data are called network nodes. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. Computer networks support an enormous number of applications and services such as access to the World Wide Web , digital video , digital audio , shared use of application and storage servers , printers , and fax machines , and use of email and instant messaging applications as well as many others. In most cases, application-specific communications protocols are layered i.

IoT Standards and protocols guide — protocols of the Internet of Things

Networking hardware , also known as network equipment or computer networking devices , are electronic devices which are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network. Networking devices includes a broad range of equipment which can be classified as core network components which interconnect other network components, hybrid components which can be found in the core or border of a network and hardware or software components which typically sit on the connection point of different networks. The most common kind of networking hardware today is a copper-based Ethernet adapter which is a standard inclusion on most modern computer systems. Wireless networking has become increasingly popular, especially for portable and handheld devices. Other networking hardware used in computers includes data center equipment such as file servers , database servers and storage areas , network services such as DNS , DHCP , email , etc. Taking a wider view, mobile phones , tablet computers and devices associated with the internet of things may also be considered networking hardware.

Network Devices Explained

Here we will have a brief overview of keypoints summearized from these web pages, reports, news analyses and technical papers. First, we will go over the market and technology potential, then we will list the keypoints further in five possible networking technologies, traditional LAN, phoneline networking, powerline networking, wireless networking including RF and wireless LAN and infra-red digital access IrDA. Then there is a discussion on the service and requirement issues for home networking. Finally an overview of current market players is given. Back to Table of Contents 2.

Internet of Things IoT constitutes the next step in the field of technology, bringing enormous changes in industry, medicine, environmental care, and urban development. Various challenges are to be met in forming this vision, such as technology interoperability issues, security and data confidentiality requirements, and, last but not least, the development of energy efficient management systems. In this paper, we explore existing networking communication technologies for the IoT, with emphasis on encapsulation and routing protocols. The relation between the IoT network protocols and the emerging IoT applications is also examined. A thorough layer-based protocol taxonomy is provided, while how the network protocols fit and operate for addressing the recent IoT requirements and applications is also illustrated.

Chapter 7. Telecommunications, the Internet, and Information System Architecture. The electronic transmission of information over distances, called telecommunications, has become virtually inseparable from computers: Computers and telecommunications create value together. Components of a Telecommunications Network. Telecommunications are the means of electronic transmission of information over distances.

    IoT protocols are a crucial part of the IoT technology stack — without them, hardware would be rendered useless as the IoT protocols enable it to exchange data in a structured and meaningful way.
