DATA LINK PROTOCOL AND COMMUNICATION NETWORKS
Similar to wide-area networks, local-area networks are an example of communication networks interconnecting several devices for information exchange. The LAN design is usually for a single floor or building, but it can also reach to multiple buildings via routers and bridges. The design is shared medium rather than switching nodes. The internal data rates for LANs are greater than for wide-area networks.

SLP 3 reviews sections 12 and 13 of the Data Communication and Networking e-textbook.

TRANSMISSION MEDIA AND DATA TRANSMISSION
Transmission media is the path between the sender and receiver. Transmission media is classified as 1) guided (such as cable and twisted wire) and 2) unguided (which is usually referred to as wireless transmission).

Additionally, the medium is controlled by the error-detection process (error detection and correction) to ensure transmission accuracy.

Parity check is an approach to error detection. In ASCII transmissions, the value bit is selected so that each 7-bit character is attached a 1 for even or odd parity. The receiving end will check, and if a 1 is inverted to 0, an error is detected. In addition, lost frames and damaged frames can occur when data is sent in frame sequence. Error control techniques include positive acknowledgment, retransmission after time-out, negative acknowledgement, and retransmission. Additionally, as an example of satellite transmission media, Keplers law is reviewed for calculating the period a signal reaches earth for satellite transmissions. The orbit section and assignment were extracted from Forouzan (2007, p. 479).

SLP 2 reviews sections 7 and 9 of the Data Communication and Networking e-textbook.

Orbit

An artificial satellite needs to have an orbitthe path in which it travels around the Earth. The orbit can be equatorial, inclined, or polar. The period of a satellite, the time required for a satellite to make a complete trip around the Earth, is determined by Kepler\’s law, which defines the period as a function of the distance of the satellite from the center of the Earth.

Example 1

What is the period of the Moon, according to Kepler\’s law?

Period:::: C x distance1.5

Here C is a constant approximately equal to 1/100. The period is in seconds and the distance in kilometers.

Solution

The Moon is located approximately 384,000 km above the Earth. The radius of the Earth is 6,378 km. Applying the formula, we get:

Example 2

According to Kepler\’s law, what is the period of a satellite that is located at an orbit approximately 35,786 km above the Earth?

Solution

Applying the formula, we get:

This means that a satellite located at 35,786 km has a period of 24 h (hours), which is the same as the rotation period of the Earth. A satellite like this is said to be stationary to the Earth. The orbit is called a geosynchronous orbit.

SLP 2 Assignment
Look up the altitude of a Globalstar satellite on the Internet. Use Kepler\’s formula to check the accuracy of a given period and altitude for a Globalstar satellite. Use the following exponent calculator to estimate the period.

http://www.rkm.com.au/CALCULATORS/CALCULATOR-powers.html

Submit the assignment answer in a 2- to 3-page Word document (excluding cover page and references) and explain how you arrived at the period using the Keplers formula.

HIGH SPEED WIDE-AREA NETWORKS
The most widely used data communication service is Frame Relay, which was developed as part of the ISDN project. It can be used in private and public network configurations. Frame Relay uses variable size pockets or frames, and the process is simpler than X.25. Data rates of 2 Megabits can be achieved.

According to Forouzan (2007, p. 453), Frame Relay provides permanent virtual circuits and switched virtual circuits. For example, Frame Relay network can be connected to the Internet and internal LANs and WANs through the use of routers. Frame Relay WANs can be used as one link in the global Internet.

SLP 4 reviews sections 17 and 19 of the Data Communication and Networking e-textbook.

SLP 4 Assignment
SLP questions were extracted from Forouzan (2007, p. 465). Use the hex converter http://www.binaryhexconverter.com/ for the following exercises.

Submit the assignment answers in a 2- to 3-page Word document.

The address field of a Frame Relay frame is 1011000000010111. What is the DLCI in decimal? What is the DLCI in binary?

Scenario:
The best-laid plans are always subject to disruption, especially when outside parties, tight deadlines, and too many people are involved. When employees do not understand their jobs’ connections to the organization’s outcomes, sometimes managers have to redirect and refocus the employees. This week’s project will help us clean up a mess caused when an outside vendor and two internal employees dropped the ball on mailing an important package by a critical deadline.
To prepare for this Assignment, you will examine the “Forever U. Case Assignment,” provided in this week’s resources. Then, you will prepare needs assessments to analyze two employees’ current skill levels, and a gap analyses on what should have happened, and what did happen in the scenario. Based on the needs assessment, you will address how to improve the performance of the mailroom specialist and the administrative assistant in their current jobs. Finally, you will create two performance improvement plans that outline for both employees their expected behaviors, metrics for improvement, steps they will take, consequences for not meeting the plan’s expectations, and their managers’ role, according to an established form.
Note that PIPs are a bit different from individual development plans (IDP), which are career management documents. Using an IDP, an employee creates a plan to develop skills over time, to prepare for new job opportunities, or promotions. Rarely are IDPs properly used to correct a missed step in work processes. PIPs are used when mistakes happen that are so egregious that the manager needs to put the worker on notice that the behavior must stop; they give the employee a plan of action.

Instructions:
As HR manager, draft the PIPs, along with instructions to the manager on how he or she should conduct a meeting with the employees about improvements and consequences. Your paper should include the following:
1. Introduction, briefly summarizing what happened.
2. Needs assessment with gap analysis (for both employees).
3. PIPs for both employees (create two Appendices for these – Appendix A and B).
4. A set of instructions for the manager on what s/he should do to implement the PIPs.
5. No conclusion is required – this is a work-based document, parts of which will go into the employees’ files.

NOTE: please Include a reference and title page. I will attach an example of a paper.

Hello Lateifa,
>
> Here is an assignment you can help with since I am not submitting the grades until Thursday inshallah.
>
> Instructions:
> Do your best to create a database of researchers of free zones and institutes that do research in free zones (worldwide). So create a table that lists institutes, their location, web addresses, research subjects and so on. Another list for prominent researchers who have a lot of research on the topic. For this list, include for each researcher what institution (university) or organization they work for, topics of research they study that is related to free zones (international economics, region of interest is China, etc) and their email addresses.
>
> Since another student had to do this I attached the work that she has done and what you can do is simply add to it.
>
> The way I helped her organize it was like this: In the first column, you will list the name of the (individual) researcher or organization that studies free zones; the second column should include which countries or areas are studied by the organization/researcher; the third column should include the research topics usually studied by the organization/researcher; the fourth column should include the location of the organization/researcher; the fifth column should include the website of the organization or email of the researcher.
>
> If you want to ask me more questions, you are more than welcome to do so. The main idea is to create a database so that if anyone has a question, they can refer to this database and say, we should call this number or visit this website or email this particular researcher.
