Exercises 3.8.2 Questions: Q3-2. What does the amplitude of a signal measure? What does the frequency of a signal measure? What does the phase of a signal measure? Amplitude: it measures the proportion of the energy that a specific area can carry it, and it always include (peak amplitude) which represent the highest intensity that carried by the area. Frequency: it used to measure “the number of periods in 1 second”. Phase: it is used to “describe the position of the waveform relative to time

1. Describe the process by which software recognizes keystrokes. Keystrokes are translated into electrical signals by the modern keyboard. They use an integrate microprocessor to generate bit-stream outputs. Pressing a key sends a coded signal to the controller, and the controller generates a bit-stream output according to an internal program or lookup table. 2. What is a font? What is point size? A font is a collection of characters of similar style and appearance. Point size refers to characters’

Red 1. What are some of the advantages and disadvantages of the ways teachers try to relate to their students? A teacher has to be relatable to their students. A connection must exist in order for any real learning to occur. A disadvantage of becoming relatable would be becoming too familiar with the students and then a loss of respect could occur. A teacher must maintain a position of authority. 2. Why do you think it is important to have challenging academic expectations for each and every student

Describe some of the health, safety & environmental risks that have been linked to CCS and explain how these risks can be quantified and communicated in an understandable way to the public. There are some risks associated with CCS that can impact health, safety, and environmental factors. If a leakage were to result, it would be hazardous to not only people but also the surrounding wildlife and ecosystems. The elevated CO2 concentrations in confined areas would play an adverse role in

1. When running Snort IDS why might there be no alert When running a new system such as Snort IDS there is always the possibility that a user’s may run into problems fetching the data. A user may have difficulties in creating the snort configuration file. The signature file or rule set or database may be pointing to the wrong location. The database configuration must have correct parameters such as username, password and database name. According to “snort.org “ an errant pass rule could cause alerts

Question 2 1) What is a computing cluster? Clustering is when two or more computers are connected to behave like a single computer. This alters the overall power, increasing processing speed and storage capacity. All the computers perform the same tasks and are normally connected by LAN. 2) Describe how the SETI@home project uses distributed computing to achieve its objectives. SETI@home operates by using computers across the globe to analyse radio telescope signals. SETI@home uses a large and sensitive
