Computer Organization
1. Define the term "sample" as it applies to digital systems.
Ans : Measure the signal at intervals.
2. Define the term "sampling rate" as it applies to digital systems.
Ans : The rate at which these samples are taken.
3. What are the two primary problems that sampling could cause?
Ans : The two primary problems of sampling , between the measurements and information can be lost due to the
rounding of the measurement.
4. Name the three parts of the system used to input an analog signal into a digital system and describe their purpose.
Ans : Sensor , Signal Conditioning , Analog to Digital Converter the purpose is to convert the analog signal to digital signal.
5. Name four benefits of a digital system over an analog system.
Ans : if an analog signal is transmitted over long distances, noise attaches itself to the signal. To keep the signal strong enough to reach its destination, it must be amplified.
All of the noise that attached itself to the signal, however, is amplified along with the original signal resulting in distortion.
6. Name three drawbacks of a digital system over an analog system.
Ans : Data is Invalid or undefined No data
in transitions data is available
7. True or False: Since non-periodic pulse trains do not have a predictable format, there are no defining measurements of the signal.
Ans : True
8. If a computer runs at 12.8 GHz, what is the period of its clock signal?
Ans : 0.078125microseconds
9. If the period of a periodic pulse train is 0.000000125 nanoseconds, what is the signal's frequency?
Ans : 800,000 Hz
10. If the period of a periodic pulse train is 50 microseconds, what should the pulse width, tw, be to achieve a duty cycle of 15%?
Ans :tw= Tx(Duty cycle)/100%
tw= 0.00000050 microseconds x 0.15
-10
tw= 7.5x10 or 0.00000000075 picoseconds
11. True or False: A signal’s frequency can be calculated from its duty cycle alone?
Ans: False

"4 sTeps 2 God"
1 God Loves You!
The Bible says, "God so loved the world that He gave His one and only Son, that whoever believes in Him shall not perish, but have eternal life"
The problem is that . . .
2 All of us have done, said or thought things that are wrong. This is called sin, and our sins have separated us from God.
The Bible says “All have sinned and fall short of the glory of God.” God is perfect and holy, and our sins separate us from God forever. The Bible says “The wages of sin is death.”
The good news is that, about 2,000 years ago,
3 God sent His only Son Jesus Christ to die for our sins.
Jesus is the Son of God. He lived a sinless life and then died on the cross to pay the penalty for our sins. “God demonstrates His own love for us in that while we were yet sinners Christ died for us.”
Jesus rose from the dead and now He lives in heaven with God His Father. He offers us the gift of eternal life -- of living forever with Him in heaven if we accept Him as our Lord and Savior. Jesus said "I am the way, the truth, and the life. No one comes to the Father except by Me."
God reaches out in love to you and wants you to be His child. "As many as received Him, to them He gave the right to become children of God, even to those who believe on His name." You can choose to ask Jesus Christ to forgive your sins and come in to your life as your Lord and Savior.
4 If you want to accept Christ as your Savior and turn from your sins, you can ask Him to be your Savior and Lord by praying a prayer like this:
"Lord Jesus, I believe you are the Son of God. Thank you for dying on the cross for my sins. Please forgive my sins and give me the gift of eternal life. I ask you in to my life and heart to be my Lord and Savior. I want to serve you always."
