The class will have a class assessment on the 16th of December, this assessment will cover all areas of the class covered.
The assessment will be based on a single past paper taken from the last 6 or so years, I will remove all the content we have not covered.
I will return the paper to you before the holidays so that you can look over the sections to need to study before the prelim.
Right, you should have finished off the prep task for next Tuesday Dec 6th.
The submission must have the following parts
No time will be given in class to print it off, if you need to print it then do so at lunch time this week or on Monday.
There are plenty of posts on the internet about image file sizes and image file types.
We discussed in class how to calculate image file sizes, however, it’s often hard for raw numbers to mean anything. We forget that file storage was not always the multi Gigabyte size it is now. Here is a way for you to try and get your head around it.
The new iPhone 4s’ camera has a resolution of 3264 by 2448 pixels @ 24 bits per pixel, how many uncompressed images can you fit on a standard 16GB iPhone 4s?
Answer the following questions.
Convert the following to decimal
How many pixels in the following files
What are the sizes of the following files in bytes
Calculate the storage requirements for the following images in Megabytes (to 2 decimal places)
OK so here is what we have covered so far.
Here is the PDF of the paper copy I plan to hand out at the end of the topic.
These notes are short and to the point, think of them as like the how to pass book. Remember you should also be using Scholar.
I posted on this last year, I don’t feel the need to go back over it. However, if you would like me to give another full post please just ask.
Remember for 8 bit 2’s complement the column headers are -128 64 32 16 8 4 2 1
The homework for tonight is to convert the following to binary using 2’s complement, the answers should be in Bytes so either 8 or 16 bits.
Have fun
All of the class have been given a login and password for the following sites. I have verified that each pupil’s login details work within the class, they have all assured me they have tested these from home.
We have been using Glow within the class this year and I have uploaded all the course notes, past papers, past course works & revision materials to the various Glow areas. All pupils are encouraged to contribute to the Glow forum & blog for the subject. Scholar has its on discussion board which is staffed by Scholar approved teachers & lecturers. Materials and quizzes can also be found on the school’s website and a copy can be lifted directly from the school’s server using a flash drive.
This term has seen the introduction of Glow mail, the pupils can use this to send messages directly to my Glow inbox. Details are given within the Glow groups.
Hopefully the pupils will make full use of these digital resources; usage stats show a slow but steady uptake.
