Question
1- What software creation by Xerox changed the way users looked at computers? Why was it important to users?
2- Look at the following statements and select the one that is more correct than the others.
Computers (PC's) of today can not be compared with the computers of 20 years ago.
Computers (PC's) of today at the most basic level are the same as those of 20 years ago.
Computers (PC's) of today at the most basic level are very different from those of 20 years ago.
d- None of these statements are correct
3- PCIe and AGP are methods to deliver data in the system. In terms of video cards, they can be very different. Provide 2 technical differences between PCIe and AGP. (you may not say 1 is this and the other isn't).
4- Virtual Memory and Swap files are a component of most Operating Systems today. Answer the following 3 questions.
1. How do you determine the correct size of the swap / virutal memory file?
2. What will happen if you set the file to low?
3. What will happen if you set the file to high?
5- Many devices may be "overclocked" in a PC...the CPU, the Video Card, etc. Provide 1 advantage and 1 disadvantage to overclocking. (They can be technical or non-technical)
6- The CPU only performs 4 items and does them all the time. These 4 tasks are?
7-
When we discussed upgrading of ANY component in class, there were non-technical items we always had to take into consideration. Ex. Use of computer for the next 3-5 years. Name 3 others NON-TECHNICAL considerations.
Question 27 options:
7- Describe what a class is when we discuss memory (flash cards) ex. SDHC, XD, etc and why it is important.
a-Computers (PC's) of today can not be compared with the computers of 20 years ago.
b-Computers (PC's) of today at the most basic level are the same as those of 20 years ago.

Question 27 options:
Blank # 1 Blank # 2 Blank # 3 Blank # 4 Blank # 5 Blank # 67- Describe what a class is when we discuss memory (flash cards) ex. SDHC, XD, etc and why it is important.
Explanation / Answer
2.a(con;t compare
3.AGP:a.AGP cards can access the system memory to help with complex operations such as texture mapping
b. AGP doesn't share bandwidth with other devices,.
pci:fPCI cards can only access the memory available on the actual card.
PCI share bandwidth with other devices.
4.
1.virtual memory size could result in performance loss if size is too high or too low
2.(not clear what size)
if memory size is low then it occupies low ammount of memoroy on RAM so then it quickly executes
3.
if memory size is high then it occupies huge ammount of memoroy on RAM so then it executes slowly.
5.advantage:by overlocking your system components your system perfomance will be increased.
disadvantage:there is no second hand sale for overlockerd devices
6.fetch,decode,executing,storing
7.xd,flash cards are emerging now because of cost,size and perfomance
