My research project is on Bluetooth technology. Bluetooth is an open wireless protocol for exchanging data over short distances between different devices and creates a Personal Area Network. Bluetooth allows devices such and mobile devices, laptops, computers, printers, and many other devices through secure short-range wireless interconnection. Bluetooth allows devices to communicate with each other wirelessly without having to use cords or any other wire to connect the devices. I currently use many devices that use Bluetooth so I am going to research how Bluetooth functionality actually works and what is required to setup Bluetooth connectivity on different devices. Bluetooth technology is a wireless technology that breaks the barrier of having to use wires and instead provides the versatility to be able to link devices such as mobile devices, computers, portable handheld devices, and connectivity to the internet. The concept behind Bluetooth technology was first discovered in 1994 by the Swedish company Ericsson when they began researching the idea of replacing cables connecting mobiles devices and computers with wireless links (Morrow, 2002). The name Bluetooth came from a 10th century Viking monarch name Harald Bluetooth and therefore was name after him due to the origin of where it was founded. They quickly realized that the potential market for Bluetooth products was absolutely huge. However, they also realized that there would need to be cooperation from around the world for Bluetooth products to succeed. This led to the formation of Bluetooth SIG in 1998 and the first Bluetooth technical specification in 1999. The early applications of Bluetooth were initially developed for mobile communication between mobile devices and computers. This was initially designed with Bluetooth wireless communication using radio frequency technology, which is using radio waves to communicate through the air in a manner fundamentally similar to broadcast radio and television. Radio frequency technologies employ transmitters and receivers tuned to produce and consume, respectively, radio waves of a given frequency range (Bluetooth SIG, 2014). Transmitters and

“The clinical microsystem is the place where patients, families, and caregivers meet. It is the lotus of value creation in healthcare.”(Nelson, Batalden, et.al, 2011)
Lilly Walden describes herself as an active, athletic, and healthy woman. In her mid-forties she continues to run 2–3 miles 5 days per week. Lilly is married with three children and is employed by the local school district as a speech therapist. Lilly describes herself as health-conscious. Her diet is balanced, and she is a nonsmoker…
such as Bluetooth and infrared communication typically form a wireless PAN.
Local area network
A local area network (LAN) is a network that connects computers and devices in a limited geographical area such as home, school, computer laboratory, office building, or closely positioned group of buildings. Each computer or device on the network is a node. Current wired LANs are most likely to be based on Ethernet technology, although new standards like ITU-T G.hn also provide a way to create a wired…
RQ3. In about 200 words, compare the POP e- mail protocol to the IMAP e- mail protocol. Describe situations in which you would prefer to use one protocol over the other and explain the reasons for your preference.
Both POP and IMAP e-mail protocols allow clients to send and receive e-mail as well as support Multipurpose Internet Mail Extensions (MIME), which are attachments such as documents, photos, and music. The Post Office Protocol (POP) runs on an email program, which connects to a…

e. Network Topology: Physical Star Topology with a central switch and a router in each location. Each office will have workstations that will form a LAN and the routers will provide communicate between each LAN and with the central insurance office.
i. The location of each switch and router is going to be separated from the main offices, in a small climate controlled room under lock and key.
ii. We are going to have fault tolerance and daily backups.…

Internet Protocol Suite
TCP/IP is not just a protocol, but a protocol suite. It encompasses many protocols, such as IP, TCP, UDP, ICMP, IGMP and so on.
The TCP/IP suite (like its conterpart, the OSI model) uses the principal of a "stack". Each level of the protocol stack solves some set of problems, and has a "payload" area. The "payload" (data) contains data in another higher-level protocol, which solves a different set of problems. And so on.
The TCP/IP model was designed as the solution to…

For a website to be accessed on the internet it needs to initially be uploaded on to a webserver. Firstly, the process of uploading involves a protocol called FTP (file transfer protocol). Ftp’ing can be done using a browser of through programs such as CuteFTP. Moreover, when webpages are uploaded onto a webserver, all other associated files should also be uploaded with it. These associated files are elements such…
