CSC 535-02 Advanced Computer Networking Home Work - 4 1) A signal has a fundamental frequency of 1000 Hz. What is its period? - Given, Fundamental Frequency (f) = 1000Hz Period (P) = 1/f =1/1000 = 0.001 Sec =1 millisecond 2) If the solid curve in Figure 1 represents sin (2πt), what does the dotted curve represent? That is, the dotted curve can be written in the form A sin (2πt + φ); what are A, f, φ? - For a given blue Solid Curve given equation is = sin (2πt) For a Dotted Curve: Phase Angle φ = 0 At time t=0, Amplitude (A) = 2V Time t = 0.5 Frequency (f) = 1/t = 1/0.5 = 2 Hz Therefore equation for Dotted Curve is = 2sin (2π*2*t+0) =2sin (4π*t) 3) Given the following frequencies listed below, calculate the corresponding periods: (a) 24Hz (find T in ms) - Given frequency f=24Hz Frequency (f) = 1/time period f = 1/T T = 1/f = 1/24 = 0.04167 seconds = 41.67 ms (b) 8MHz (find T in micro seconds) - Here, frequency f =8MHz = 8 *106 Hz T = 1/f = 1/8*106 Hz = 0.125*10-6 sec = 0.125 micro seconds (c) 140 kHz (find T in micro seconds) - Here, frequency f= 140 KHz f = 140 * 103 Hz f = 140 * 103 *103 /103 = 140* 106/1000 =0.14 * 106 T = 1/f
Explain the key components required for client workstations to connect to a network and access network resources.
Given the following proposed circuit an are required to re-implement is functionality using the minimum umber of gates possible. Using K-maps to achieve this outcome.
Something that really struck out to me was the topic of networking. In Chapter 2, author, Don Raskin goes into depth about the importance of networking. What Raskin says about networking really makes a lot of sense because it is much easier for companies to make hiring decisions based on recommendations from a trusted source than hiring someone through the interviewing process. Employers can get an idea of who the interviewees are, but having people recommended to them makes their job way easier. Networking is something that I will definitely do to my fullest when I look for an internship/job. Getting to know many influential people that will help me better my career will really set me aside from others. Having as many connections as possible
1. List two advantages of wireless networking. User mobility in the workplace, and cost effective networking media for use in areas that are difficult or too costly to wire.
I will be on vacation on August, so tomorrow will be the last time I will try to start and finish this task because I have a lot of work I need to finish before going on vacation.
For each received frame, use the data-link trailer frame check sequence (FCS) field to ensure that the frame has no errors; if errors occurred, discard the frame (and do not continue to the next step).
The PCNet project has run into some issues which are going to take an effect on this project.
When a CPU is composed of two or more processors, each one is referred to as a(n) ________.
y = sec x, - £ x £ , stating the coordinates of the end points
Riordan Manufacturing is a very large company. Because of this, Riordan is made up formal and informal power structures. Companies typically have an organizational chart that lists the relationship and ranks of positions within the company. Formal power may refer to position on the corporate ladder, corporate structure or even job function. The most powerful person in your department is not necessarily your manager. Informal power in an organization refers to the ability to lead, direct or achieve without an official leadership title. The power and political structure of the organization does affect employee behavior.Interaction between various levels of hierarchy requires employees to
The first tutorial I chose was Computer Security by Rozeberger and Zeldich. The tutorial gave a basic overview of computer security, including viruses, worms, and Trojan horses. It discussed how to avoid attacks or at least to become aware of the potential of attacks. The tutorial also looked at how hackers work, to help explain how breaks are performed. I chose this tutorial because I believe that computer security is one of the most significant and serious issues for any emerging IT professional. It a network is not secure, it will become vulnerable to attack by hackers. Therefore, any other work that an IT professional does on a computer must be considered secondary to the safety of the network.
Step 7: Destination device send the Address Resolution Protocol (ARP) reply message and it will not be a broadcast, but a unicast.

Computer technology and networking have wide ranges of needs to keep it secured while providing fast service to its users. One way this can be done is through cybersecurity, the protection of information by using technologies and processes to defend a computer or network from attacks and unauthorized access. Many people don’t exercise enough cyber protection and get security problems in multiple ways. There are the more well-known hacking attempts where people get into other’s accounts and steal information or, sometimes, money. There are also attacks that aren’t easily identified, like phishing emails that lure people to click links or send personal information with fake emails. There are many different types of attacks that could harm individuals and businesses, but there are techniques used in cybersecurity that help to prevent and stop those assaults. An example of an older, outdated approach is Wired Equivalent Privacy, or WEP, which is an encryption technology ratified in 1997 that is now easily hackable. Newer technologies are coming out that can improve protection procedures and create a safer world. However, there are also methods and hardware that are becoming popular that make it easier for cyber criminals to attack others and cause harm. Some newer technologies that are impacting cybersecurity in many ways are artificial Intelligence, deception technologies, Graphics Processing Units, and quantum computing.
