The Processor

For your Blog notes you need to write about the following (use the teacher's presentation to help you):

1.  What is the computer processor?

2.  What does it do?

3.  How many tasks can the processor carry out at one time?

4.  How does it  manage to do lots of tasks?

5.  What is the speed of a processor?  How is it measured?

6.  How many instructions per second can a 1Hz processor execute?

7.  Which is faster - a 5MHz or a 2GHz processor?

Storage devices and binary

Here is the work that you need to do.  (You can look at the teacher's presentation in lesson 3 of the Building a Computer unit for help).

1.  Open a new post on your Computer Science blog and title the Post the same as this one.

2.  How do computers use binary code?

3. What numbers in binary code represent the electric current inside the computers being turned off and on (don't forget to say which is on and which is off!)

4.  Write a short description of the activity you did with torches sending messages to each other.

5.  Explain why the more "bits" that are in a code give more colours (this is from your Binary Images spreadsheet work). 

6.  Write down the information from the teacher's presentation, slide 8, explaining the different units of data storage (bits, bytes, etc).

7.  When you have done all the work above, click Publish!  :-)

8.   If you don't finish this in the lesson, you'll need to either finish it at lunchtime or at home.  Deadline is by the end of the weekend, ready for next week!
