2. Read the following excerpt on 'Clock Speed'. Is it true or false?
3. The image below shows an Intel CPU. Read the paragraph below and fill in the blanks.
4. The performance of the CPU is directly related to the performance of your personal computer. There are four factors (The 4 Cs) to consider. Fill in the blanks.
5. Who is the image below and the paragraph describing?
6. Two brains are better than one right? And four brains are even better. Multiple cores are a key factor in performance. Read the following paragraph and fill in the blanks.
7. The Neumann architecture design consists of a Control Unit, Arithmetic and Logic Unit (ALU), Memory Unit, Registers and Inputs/Outputs. One of the main purposes of the CPU is to ...
8. Although CPUs fetch instructions from RAM, there is another place they can get instructions from, called _______.
9. The speed that a CPU works at is measured in _____, Hz. Modern processors often run so fast that gigahertz, GHz, is used instead. One gigahertz is one billion _____.
10. Cache is like RAM but the one difference is that it is much ___________ to read and write from it rather than from RAM. This obviously speeds up CPU performance.
11. Ever wondered how your brain is involved in executing an instruction? For instance, if someone says "Pass the salt"....what happens?
12. The fetch-decode-execute cycle is the sequence of steps that the CPU follows to process instructions. This is also sometimes called the ...
13. Here is a diagram (Source: BBC Bitesize) of the Fetch Decode Execute cycle. Out of the following options, what happens first?
14. The next steps that occur in the Fetch Decode Execute cycle are shown in the excerpt below. Can you fill in the blanks?
15. The three stages of the FDE cycle are 'Fetch', 'Decode' and 'Execute'. What happens in the fetch stage?
16. What happens in the decode stage of the FDE cycle?
17. What happens in the 'execute' part of the FDE cycle?
18. Why is the fetch decode execute cycle called a cycle?
19. The program counter stores the memory address of the next instruction to be fetched. What happens when that address has been used?
20. What is overclocking?
21. Parallel and multi-core processing both refer to the same thing: the ability to __________________________________ (in more than one core/CPU/machine.) So in this sense multi-core is just a means to do parallel processing.
22. Analyse the "pipeline" below and fill in the blanks.
23. The image shows an Intel CPU with a math co-processor. What is a co-processor?
24. Describe how the CPU and RAM work together to make a tablet computer work and execute instructions/programs?
25. This would perform an operation such as 5+8 (1-4)
26. This would reduce the number of memory/processor transfers
27. This sends signals such as ?I/O Read?
28. This doesn?t happen during the Fetch part of the cycle:
29. Which of the following is held in ROM?
30. What carries the address of the next instruction that will be fetched
31. One of the properties of an address bus is that it is uni-directional.
32. Developments in the field of storage are progressing every day. There is talk of 'embedded storage chips' becoming common place. Can you name one more type of storage that is not on the below list.
33. A storage device is sometimes defined as devices used to store data in binary format (used for processing later). Which of the following in the list is NOT a storage device?
34. An E-Book reader would be best off using a particular type of storage for the following reasons. What type of storage is this likely to be referring to?
35. The online company TechHamper is producing a free e-book to distribute to its customers about the latest technology items. Which of the following reasons are valid for why a CD-ROM might be best?
==Advantages of Opitcal Storage=====
#1 Cheap to Produce
#2 Expensive to Produce
#4 Enough capacity for something like an e-book
#5 Can easily be read by other devices (e.g. computers)
#6 Read-only (cannot write over it)
#7 Massive capacity for storage
#8 No moving parts / reliable and robust
