I/O port address and IRQ 9) What is the name of the process by which a network interface adapter determin es when it should transmit its data over the network? Media Access Control 10) Which bus type is preferred for a NIC that will be connected to a Fast Ether net network? PCI 11) A passive hub does not do which of the following? Transmit management information using SNMP 12) To connect two Ethernet hubs together, you must do which of the following? Connect the uplink port in one hub to a standard port on the other 13) Which term describes a port in a Token Ring MAU that is not part of the ring ? Intelligent 14) A hub that functions as a repeater inhibits the effect of____________? Attenuation 15) You can use which of the following to connect two Ethernet computers togethe r using UTP cable?

A hub 4) To achieve 100 Mbps speed over Category 3 cable, 100BaseT4 Ethernet uses whic h of the following? All four wire pairs 5) In which of the following standards is Gigabit Ethernet defined? IEEE 802.3z 6) The Frame Check Sequence field in a data-link layer protocol header is used f or ____________? Error Correction 7) List the hardware components that you have to replace when upgrading a ten-ye ar-old 10BaseT network to 100BaseTX? The components are NICs, hubs and cable (because a 10 year old network is most l ikely using Category 3 cable, and Category 5 is required for 100Base TX.) 8) How could you upgrade a ten-year-old 10BaseT network to Fast Ethernet without replacing the cables? Use 100Base T4 and hubs. 9) Which data-link layer protocol is preferred on a network with high levels of traffic, Ethernet or Token Ring? Why?

  • Gigabit Ethernet - CH 3 - Ethernet, Fast Ethernet, and Gigabit Ethern
    Switched, Fast, and Gigabit Ethernet - CH 3 - Ethernet, Fast Ethernet, and Gigabit Ethern.. Page 1 of 36 [Figures are not included in this sample chapter] Switched, Fast, and Gigabit Ethernet - 3 - Ethernet, Fast Ethernet, and Gigabit Ethernet Standards This chapter discusses the theory and standards of the three versions of Ethernet around today: regular 10Mbps Ethernet, 100Mbps Fast Ethernet, and 1000Mbps Gigabit Ethernet. The goal of this chapter is to educate you as a LAN manager or IT professional about essential differences between shared 10Mbps Ethernet and these newer technologies. This chapter focuses on aspects of Fast Ethernet and Gigabit Ethernet that are relevant to you and doesn’t get into too much technical detail. Read this chapter and the following two (Chapter 4, "Layer 2 Ethernet Switching," and Chapter 5, "VLANs and Layer 3 Switching") together. This chapter focuses on the different Ethernet MAC and PHY standards, as well as repeaters, also known as hubs. Chapter 4 examines Ethernet bridging, also known as Layer 2 switching. Chapter 5 discusses VLANs, some basics of routing, and Layer 3 switching. These three chapters serve as a precursor to the second half of this book, namely the hands-on implementation in Chapters 8 through 12. After you understand the key differences between yesterday’s shared Ethernet and today’s Switched, Fast, and Gigabit Ethernet, evaluating products and building a network with these products should be relatively straightforward. The chapter is split into seven sections: l "Ethernet and the OSI Reference Model" discusses the OSI Reference Model and how Ethernet relates to the physical (PHY) and Media Access Control (MAC) layers of the OSI model.

Email: [email protected] Received: 15 January 2021; Accepted: 17 February 2021 Abstract: Wireless sensor network (WSN) is considered as the fastest growing technology pattern in recent years because of its applicability in var- ied domains. Many sensor nodes with different sensing functionalities are deployed in the monitoring area to collect suitable data and transmit it to the gateway. Ensuring communications in heterogeneous WSNs, is a critical issue that needs to be studied. In this research paper, we study the system performance of a heterogeneous WSN using LoRa–Zigbee hybrid communi- cation. Specifically, two Zigbee sensor clusters and two LoRa sensor clusters are used and combined with two Zigbee-to-LoRa converters to communicate in a network managed by a LoRa gateway. The overall system integrates many different sensors in terms of types, communication protocols, and accuracy, which can be used in many applications in realistic environments such as on land, under water, or in the air. In addition to this, a synchronous man- agement software on ThingSpeak Web server and Blynk app is designed.

  • PCI20EX PCI Express (Pcie)
    PCI20EX PCI Express (PCIe) Bus ARCNET® Network Interface Modules INSTALLATION GUIDE INTRODUCTION The PCI20EX series of ARCNET network interface modules (NIMs) links PCI Express (PCIe) bus compatible computers with the ARCNET local area network (LAN). Since most PC motherboards have migrated from the legacy PCI and PCI-X Bus, a PCI Express style NIM is required. The PCI20EX series is compliant to the PCI Express Card Electromechanical Specification Revision 2.0 and both standard height and low-profile brackets are provided. The PCI Express interface allows for jumperless configuration and Plug and Play operation. The module operates with either an NDIS driver or a null stack driver in a Windows® environment. The PCI20EX incorporates the COM20022 ARCNET controller chip with enhanced features over the earlier generation ARCNET chips. New features include command chaining, sequential access to internal RAM, duplicate node ID detection and variable data rates up to 10 Mbps. Bus contention problems are minimized since the module’s interrupt and I/O base address are assigned through Plug and Play. The PCI20EX exploits the new features of the COM20022 which includes 10 Mbps communications utilizing the various EIA-485 transceiver options. Each PCI20EX module has two LEDs on the board for monitoring network operation and bus access to the module. It is equipped with an 8 position, general purpose DIP switch typically used to assign the ARCNET node address. Ultimately, the node address is configured via software so the DIP switch can also indicate user-defined functions such as data rate, cable interface, or master/slave status of the system.
