Xenix
Definition
Essentially the first real version of unix that ran on the very first IBM computers back in the 70's. It is claimed to have many similarites to BSD unix and over the years has been rewritten many times.
Shell
Definition
A program that reads and decodes comand line inputs as a program. Essentially a big list of command line inputs that run like any other program.
Demonstration
echo "enter first number: " read num1 echo "enter second number: " read num2 echo "enter third number: " read num3 echo "enter fourth number: " read num4 sum=`echo $num1+$num2+$num3+$num4 | bc` echo "The sum of the numbers is: $sum" product=`echo $num1*$num2*$num3*$num4 | bc` echo "The product of the numbers is: $product"
process ID (PID)
Definition
This is a sort of a filing system for unix that assigns a specific and permanent number to a process the entire time that process is in mrmory. Very handy if you want to kill the process later as this number gives you direct means of telling the OS what to kill.
Demonstration
ps command displays the processes aslong with their corresponding PIDs
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND jhammo13 12321 0.0 0.1 13688 2064 pts/14 SNs 10:02 0:00 -bash jhammo13 12615 0.0 0.0 8588 988 pts/14 RN+ 10:06 0:00 ps u jhammo13 13014 0.0 0.0 13660 8 pts/37 SNs Jan24 0:00 /bin/bash jhammo13 13018 0.0 0.1 42536 1888 pts/37 SN+ Jan24 12:32 irssi
Swapping
Definition
This is a technique used by Unix's kernel in order to free up memory in times of extreme memory shortages or when a process has idled for a certain period of time.
Priority
Definition
This is a number that forces the Unix kernel to run more efficiently eith processes. The number inidicates to the kernel how often the individual process is used, therefore when the kernel sees a number indicating the process is used very often it targes that process and completes it more quickly than one of low priority.
Flag
Definition
This is a variable set to indicate that some condition in the program has been met.
Demonstration
If a useris chaecking for a certain condition such as the end of a file within a program, when the end of that file is reached the flag will be 'set.'
Centralized Server Farms
Definition
Databases that store a large magnitude of data so that an end user does not have to store it all locally. However, as the client needs large amounts of this data the bottleneck becomes the network.
Power Workgroups
Definition
A set of clients in a LAN that must send and receive large amounts of data in small amounts of time resulting in a need for a faster LAN.
hpc0 Objective
hpc0 Objective
State the course objective
Definition
In your own words, define what that objective entails.
Method
State the method you will use for measuring successful academic/intellectual achievement of this objective.
Measurement
Follow your method and obtain a measurement. Document the results here.
Analysis
Reflect upon your results of the measurement to ascertain your achievement of the particular course objective.
- How did you do?
- Is there room for improvement?
- Could the measurement process be enhanced to be more effective?
- Do you think this enhancement would be efficient to employ?
- Could the course objective be altered to be more applicable? How would you alter it?

Elastic Traffic
Definition
Adjusts over wide ranges to changes in delays and throughput and still meet the needs of its applications.
Inelastic Traffic
Definition
Does not adapt if at all to changes in delays and throughput.
Analog Signal
Definition
This is a smooth continuous signal and usually thought of in an electrical context. An advantage of analog is overall quality of a signal being better but analog is a lot harder to reproduce.
Digital Signal
Definition
This mantains a constant level for some period of time and then abruptly changes. This is a poorer quality than analog but is easier to reproduce.
Simplex
Definition
A data transmission that can only go one way on the medium
Demonstration
A television set. It can only receive signals from the cable company over the coax and display them on youe tv. It cannot receive input from you and senf it back to the cable company over the coax.
Half Duplex
Definition
There is trnsmission both ways over a medium but the transmissions cannot take place both ways at the same time.
Demonstration
Walkie talkies allow two people to communicate both ways but they cannot communicate simultaneously.
Absolute Bandwidth
Definition
In a wave refereing to data transfer this is the spot in the wave where most of the energy in the signal is caontained in a realatively narrow band of frequencies.
Full Duplex
Definition
There is transmission both ways and at the same time.
Demonstration
A telephone allows two end users to communicate and they can also speak simultaneously and neither one of them gets cut out.

Experiments
Experiment 4
Question
What is the question you'd like to pose for experimentation? State it here.
Resources
Collect information and resources (such as URLs of web resources), and comment on knowledge obtained that you think will provide useful background information to aid in performing the experiment.
Hypothesis
Based on what you've read with respect to your original posed question, what do you think will be the result of your experiment (ie an educated guess based on the facts known). This is done before actually performing the experiment.
State your rationale.
Experiment
How are you going to test your hypothesis? What is the structure of your experiment?
Data
Perform your experiment, and collect/document the results here.
Analysis
Based on the data collected:
- Was your hypothesis correct?
- Was your hypothesis not applicable?
- Is there more going on than you originally thought? (shortcomings in hypothesis)
- What shortcomings might there be in your experiment?
- What shortcomings might there be in your data?
Conclusions
What can you ascertain based on the experiment performed and data collected? Document your findings here; make a statement as to any discoveries you've made.

Resources
Evaluate their resources and commentary. Answer the following questions:
- Do you feel the given resources are adequate in providing sufficient background information?
- Are there additional resources you've found that you can add to the resources list?
- Does the original experimenter appear to have obtained a necessary fundamental understanding of the concepts leading up to their stated experiment?
- If you find a deviation in opinion, state why you think this might exist.
Hypothesis
State their experiment's hypothesis. Answer the following questions:
- Do you feel their hypothesis is adequate in capturing the essence of what they're trying to discover?
- What improvements could you make to their hypothesis, if any?
Experiment
Follow the steps given to recreate the original experiment. Answer the following questions:
