Notes from lecture

Facebook:

People express their disclosure online to attract the attention of other users. We don’t care what we write about as long as we get a response-it makes us feel like we’re cared and loved by others and gives us the feeling that we’re worth something. It has taught us to tell the world everything we do. Our responses and comments make us want to tell the world more. “Facebook taught us to tell the world everything we do”.

Privacy:

Definition: The ability of an individual or group to seclude themselves or information about themselves and thereby reveal themselves selectively.

If you block everything your not teaching kids anything about privacy. What your doing is not teaching them what to leave exposed and what to keep private.
 Blocking and monitoring school internet activity teaches students that trying to keep private is a bad thing and you should learn to accept that there will always be someone watching over you.

A.

Why backup...?

You should backup whenever your wanting to save files or any data to be used again in the near future.Depending on how much data your wanting to save and the format they're in there are many options to choose from including CD-R's and DVD-R's(for music and general animation),CD-RW's and DVD-RW's(for music and general animation however you have the ability to delete and re-add files),DVD-RAM(same properties asDVD-RW but with quicker access and easier to overwrite data),Blu-ray(better sound and picture quality than the standarised DVD,can hold 25gb,50gb and 100gb)memory sticks(can store many gb's and are small and easy to transfer data from computer to computer)

Reasons for Backing Storage (class work)

DVD would be used over blu-ray because blu-ray players are more expensive and aren't built into any teacher's laptops. Also blu-ray dvd's aren't as popular as the standard dvd and are quite expensive to buy. However blu-ray dvd's offer higher quality in picture and sound and can store 25,50 and 100GB onto a single disk.

DVD-R's would be used over a DVD-RW disk in case of data being accidently deleted. However DVD-RW's are useful and more appropriate when you're constantly saving and deleting different projects onto the disk.

However the best storage devie would have to be the simple though effective memory stick. These can store mane GB's of data without having to delete items already on it. They're small and loading and copying time is fast.
