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 automation and networking purposes in…

Even though VANET is considered as a type of MANET, it has its own particular features that make it different from MANET. These characteristics include: 1. Each vehicle is turned into a router or wireless node with the capability to connect and become a part of a network in the range of approximately 100-300m. 2. Network topology changes as the vehicles fall out of range or new vehicles join the network, thus making the network density vary according to traffic density. For example, network…

positive values. A role model can be an actress, sports star or even a super hero, it should be a person that could give inspirations to make a right decision or achieve some goal. I like to introduce my role model who is an internet entrepreneur and computer programmer, Mark Elliot Zuckerberg. He was born on 1984 in White Plains, New York. He is the founder of Facebook and also known as the youngest multibillionaire of the world in 2012. He is a successful person and made a great website to…

The HC-05 is a serial Bluetooth module for transparent wireless serial communication. It communicates with the microcontroller using serial port [5]. It operates in the 2.4 – 2.485 GHz frequency band The HC-05 has 6 Pins. Table 3.1 Pin description of HC06 Pin Description Key to toggle between data mode and command mode, if set to high, it works as command mode, but default is data mode. RXD Receive data serially (received data will be transmitted wirelessly by Bluetooth module). TXD Transmit…

INTRODUCTION A network refers to a group of computers and other devices that are connected together usually by communication lines. The internet is a global network connecting millions of computers throughout the world allowing them to send and receive information. When it comes to multimedia communication both the internet and the network are vital platforms since multimedia elements such as graphics, videos, texts and audio need to be sent from one computer to another. As we know sending a…

concerns, iSCSI has a high security risk than the risks of NAS storage system. 4) NAS provides a faster data transfer rate and work performance since it is working in local network without any long distance traffic issues. iSCSI is based on Internet networking for connecting remote server which needs more latency time on the traffic. (“Iscsi vs NAS”, n.d.) 3. List 6 major strengths of SAN. (6 pts) 1) Reliable and fast performance because SAN has its own private network which does not affected by…

workers to work from property in their off hours if necessary. You will discover powerful 2.5GHZ pace pocket book computer systems obtainable for nearly as inexpensive as their desktop counterparts. Making use of a major enterprise brand for instance Toshiba, HP, or IBM (Lenovo) is actually a smart move, as is obtaining some extra warranty against breaking. Notebook personal computers break much more usually as they 're a lot more apt to slip and hit the floor. If you happen to be going to have…

six-hour-long competitions several times a year. These competitions are an integral part of CyberPatriot, a national computer security education program for high school students. For nearly the entire six-hours, I focus on securing a Linux system by using command line, editing server configuration files, and digging through the Linux filesystem, while my teammates complete networking quizzes and work on securing Windows systems. During competitions and weekly meetings, we made frequent use of…

Boarding school was liberating, so much so that I focused almost solely on my computer science passion to the detriment of other subjects. I founded the Programming Club to teach peers to code well beyond the two school computer science (CS) classes offered, resulting in furthering my coding knowledge to prepare for growing classes. Naively, I plotted ideas to become the "next big thing". Needless-to-say my report cards showed one cannot be a genius without studying. Despite having built an…

Application / Files sharing between computers Windows Homegroup Windows home networking has been extremely complicated to configure in the past, but Homegroup is easy to set up. Just create a Homegroup from the Homegroup option within Windows Explorer (File Explorer on Windows 8) and you’ll get a password which enables you to access fromyour nearby computers and they can join your Homegroup. The other members of the Homegroup will now have access to your shared files when they log ON to the…
