One of the foremost changing technology trends of the past decade is the accessibility and growing anticipation of universal connectivity. Whether it is for checking email, carrying a voice conversation, web browsing, or innumerable other use cases, we now expect to be able to access these online services regardless of location, time, or circumstance: standing in line, on the run, , on a subway, while at the office or in flight, and everywhere in between. Today, we still must be proactive in…

Q1.Ethernet has become the standard for LAN communications. Give a brief overview of structure of an Ethernet frame. Ethernet and Wi-Fi are the most commonly used technologies to set up Local Area Networks today. It operates by using Carrier Sense Multiple Access Detection (CSMA/CD) to control media access. (Study CCNA, 2016) The structure of an Ethernet Frame is as follows: The Ethernet Frame Structure (Anon., 2013) Explanation: • Preamble: This field is responsible for harmonizing bits…

1.1 Describe common physical network topologies Topologies Topologies describes the how different computers or other devices in a computer network is arranged. Topologies can be either physical (meaning placement of the components are arranged in a particular shape) or logical (meaning how data flows despite of its physical layout). There are different recognised topologies including star, mesh, tree and ring. In a star topology, each network device (computer or peripheral) is linked to a…

ABSTRACT This paper basically compares various wireless networking technologies which can be used for industrial automation and sensing. Among all these technologies, special emphasis is given on Zigbee. Zigbee is a technology known for its low power consumption, low data rates, and self-healing reliable networks, which makes it very efficient for industrial applications. The layer by layer protocol stack architecture of Zigbee illustrates these advantageous features. Zigbee is used for…

range of the signal. WLAN came about in the early 90s but was very expensive so you wouldn’t have a wireless router in your home back then. It wasn’t till the late 90s when it began to become cheaper. Most WLAN and proprietary protocols were using IEEE 802.11 either 802.11A through to 802.11N, prices for this declined rapidly making it more affordable. What WLAN does is extends your LAN connection where a wired connection cannot, you would then connect to this through your access point…

technology was used to connect these devices 1. Switch to hub 2. Hub to hub 3. Router to router 4. Pc to pc. Wi-Fi Technology This was used to connect the electronic devices used in the network using the 2.4-gigahertz. Our Wi-Fi network is based on the IEEE 802.11 b/g standards, which is the most commonly used…

AN OVERVIEW OF TELEMATICS 1.1 INTRODUCTION Telematics established in 1987 and later acquired by Bahri & Mazroei is a provider of Converged Building Systems, which covers ICT Systems (Information and Communication Technology) like Structured Cabling, Data Networks, Telephoning, etc. and ELV (Extra Low Voltage) Systems like Security, Fire, BMS, Guest Room Management Systems and Car Park etc. Telematics has “ISO 9001:2008; ISO 14001:2004 and OHSAS 18001:2007 certification” and it’s arena…

Vertical Handover Abstract: In this era of technology, next generation wireless networks are very popular that allow users to connect to different radio access technologies such as UTMS, WiMax, GSM, etc. In such heterogeneous environment Vertical Handover is executed thus a user can switch among different radio access networks that makes whole process so complex. Vertical Handover algorithms require many parameters such as interference power, QoS, network conditions, terminal capabilities,…
