Safebrace Project: A Case Study

Module 1 establishes the framework of networking standards and protocols for the rest of the class. The module introduces data communications and defines their components and the types of data exchanged. You will learn how different types of data are represented and how data is flowed through the network.

As we all know, the growth of computer networks continues to rapidly grow. The digital revolution has changed the way we work and communicate almost beyond recognition. Provided that, foreseeing the changes and potential compatibility problems, in the mid nineteen eighties, the international standard organization (ISO) developed a networking reference model to standardize how network systems communicate with each other. It is a logical model for how network systems are supposed to communicate with each other. It breaks down the different components of the network communication and puts them into layers which reduce complexity. This reference model consists of seven layers: Application Layer, Presentation Layer, Session Layer, Transport Layer, Network Layer, Data Link Layer, and the Physical Layer. Each layer provides a service to the layer above it in the protocol specification and then communicates with the same layer’s software or hardware on other computers. It's important to realize, that these layers are separated into 2 sets: Transportation Set (Laters 1- 4) and Application Set (Layers 5 – 7). More importantly, the OSI model is 7 logical

1. The device layer is responsible for communicating with a specific subsystem’s devices.It is present in every

With this in place Kudler will keep using the ANSI standards when designing and developing the new systems. Along with these standards the system will need to work on a common communication protocol in order for all devices to be able to talk to each other as well as transfer data and other information correctly and efficiently.

Protocols - a protocol is the special set of rules that end points in a telecommunication connection use when they communicate, protocols also specify interactions between the communicating entities. (Tech target, 2004)

A communications protocol characterizes the guidelines for sending pieces of information starting with one hub in a system then onto the next hub. Conventions are regularly characterized in a layered way and give all or part of the administrations indicated by a layer of the OSI reference show. A convention characterizes the operation of the convention and may likewise propose how the convention ought to be actualized. It comprises of three sections:

This section gives the details and specification of the hardware on which the system is expected to work.

Testing of the entire system will be performed to verify that all parts and counterparts are functional. This is the testing that is made prior to release. Tests performed in this stage verify for the following:

3. Specify the standard transmission distance and transfer speed for the wireless technology you identified.

Host A will use application for the OS while allowing the PC to still communicate to other devices. Transport will control the data sent and received. The network will place IP addresses to the packets allowing data to be added to the MAC addresses and physical link between host and lines.

Predication: On 09/21/17, Store Manager (SM) Anna Smirnov-Rodriguez contacted Asset Protection Manager (APM) regarding Beauty Consultant (BC) Ebony Bourne who was suspected of violating the Be Safe Policy.

Newer cruise control systems are being tested to combat this issue through use of GPS systems.

ET2 Sturges is the “Go-To-Technician” for the DGPS Bullpen. He has yet to be given tasking that requires rework on his efforts and never requires direct supervision. When the Asset Line needed to test 114 GPS receivers, ET2 developed a system to quickly test them all in 25% of the original time it would take.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

Transmission Path Level: This extends between network elements that assemble and disassemble the payload of a transmission system. For end-to-end communication, the payload is end-user information. For user-to-network communication, the payload may be call-control signaling information (call setup and call termination). Cell delineation and header error-control functions are required at the end points of each transmission path.
