In order for network devices and applications to communicate with each other, they must follow protocols and specific rules that are laid out by the Open System Interconnection (OSI) and Transmission Control Protocol/Internet Protocol (TCP/IP) model. In order for data to travel from one device to another, seven layers were created for the OSI & TCP/IP model. These seven layers are a basic standard, utilized by most networks today and are based on the OSI. Even though the OSI model is standard…
There are many technical requirements. One requirement is to have a internet connection. The environmental requirements are power source, operating latitude and an operating system platform. Table 4: Technical Requirements of HWD (Weng M. , 2016) Environment Temperature: -4° to 113°F Operating altitude: less than 30,000 feet Compatibility Iso Android Windows Sync Method Bluetooth 4.0 or 4.1 Bluetooth Low Energy 2.7 Leading Healthcare Wearable Device Brands Wearable continues to develop…
This report investigates three mini cases as provided by the brief (insert book title), these include Big E. Bank, Global consultants and Atlas advertising. The first mini case Big E. Banking (BEB) discusses the problems with connecting networks together over a wide area, all using different protocols to communicate. The second mini case addresses the problems with software acquisition including the methods used to communicate across different software products. The third mini case investigates…
3. Results and discussion 3.1. Grafting of CNT on the ramie fabric The schematic representation for the mechanism of ramie fiber surface treatments is shown in Fig. 2. For the alkali treatment of ramie fiber, the NaOH reacts with the hydroxyl groups of the ramie fiber as shown in Fig. 2(a). During silane treatment, the hydrolysis of silane takes place initially (Fig. 2(b)) which then reacts with the active hydroxyl functionalities in ramie fiber (Fig. 2(c)). Each silane molecule has three…
After adding up all these costs of living for a single person the total per month will come to around $1,436.00. Even with everything added in it still falls way short of the total monthly cost of living the almost same lifestyle at the Staybridge suites which would be around $3,678.30. That come to a total difference of $2,248.30 meaning one would have to pay almost double to live in this hotel rather than renting. After all my research it is obvious that it does not economically make sense…
1. I agree that increasing the router memory to infinite cannot control congestion because even if routers have an infinite amount of memory, congestion gets worse, because by the time packets reach to the front of the queue, they have already timed out (repeatedly), and duplicates have been sent. 2. Flow Control vs Congestion Control It ensures that the sender only sends what the receiver can handle. The congestion control makes sure that everyone across a network has a "fair" amount of…
Figure 3 demonstrates the 3 layers that make up the SDN structure. Lowest layer represents the Infrastructure Layer or Forwarding Plane, mainly focusing on data forwarding but it also takes care of monitoring local information and gathering statistics. Next layer represents the Control Layer or Control Plane which is responsible for programming and managing the Forwarding Plane. Control Plane makes use of the information gathered by the Forwarding Plane in order to define the route and operation…
1. What file transfer protocols would you recommend? Be prepared to support your recommendations. The Data Link Layer allows various protocols to transmit data between nodes in a network. This layer involves framing of data, synchronization of nodes and multiplexing of nodes. The Transfer Control Protocol (TCP) and High-Level Data Link Control (HDLC) ensure the reliability of data. They ensure that data transfers from one node to the other without any error. Moreover, the data is transferred…

the layers in an interface showing each other of the points in the corresponding layer in the TCP/IP protocol suite. I will also be describing the type and functions of entities and the service they provide. A) The way communications are done between a computers on a network is through protocol suits. The most used protocol suite and commonly available protocol suite is TCP/IP protocol suite. A protocol suit contains a layered structural design where each layer represents some functionality…
