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.

5 Qustions on exam

Q.Define hardware
A.The physical components of a computer system,in the form of computer hardware.

Q.Define software
A.One or more computer programs held in the storage of the computer for purposes.

Q.Describe what is meant by the term 'file'.
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.

Hardware:the physical components in a system eg.harddrive,
Software:disk utility software is used to change the system(control panel in system preferences) 3 types=
-set of commands
-operating system
-application
Components of a general-purpose computer: input device (eg. keyboard,mouse) CPU, RAM(random access memory)-holds what's going on now/ ROM(read only memory(non-volatile), Secondary Storage(hardrive), Output(printer)

The masters text box are only for changing style eg. red size 11

Don't use the 'side masters' text box to replicate a word onto every slide. Delete the masters text box and replace it with one of your own.

Remove the bottom three boxes on each side or ignore them as 'slide master' ignores them completley, add a new text box and put the function into it.Don't add the page numbers manually.

Remember main areas of the 'slide master' and just text and colour,everything else is just a guide-you must use your own textbox in an exam

100 words 4 fav. lesson today

My favourite and most interesting lesson today was P.E. because i learnt how to successfully do triple jump. After many fails i sat back and watched others do it and found the technique to be rather simple. Instead of doing the skip i was doing a normal and casual step. After correcting my mistake i landed on the 10.1m mark. It wasn't the best but i felt that i had learnt and accomplished something that lesson that i might be able to take up next year as a main sport or even as something on the side. In previous years i had either failed or had got a estimated mark.

1.CSV file= Comma Seperated Values(Standardized Format)
2.Absolute and relative references(relative cell references means formula changes to where you copy and paste it)Changes the numbers relative from where you moved from eg.A1+B1|B1+C1.
Absolute means it will always refer to that cell even if you copy and paste the formula from somewhere else.
$=Absolute Cell References, /=Divide, *=Times
3.-Named Cells means to change names to make cells easier, is an automatic absolute reference.
   -Named Range is an automatic relative reference, all class marks named ''marks''
  -It makes reading formulas easier, if you are naming the information rather saying B1,D1 etc
4.Sun,Average,Maximum,Minimum,Integer,Rounding,Counting,IF,Lookup
5.(Filtering)Perfrom searches using AND,OR,NOT,LIKE,>,<,=,>=,<=
6.Perform searches using wildcards(broaden searches)
7.Sort data
8.Adjust row height,column width,cell sizes
9.Colour/shading Cells
10.Set titles,use headers and footers
11.Format numeric data

Interface: One thing talking to another, allows communication. Allowing you to talk to the machine.GUI(graphical user interface) GUI's are WIMPS(windows,icons,menus,pointers),Command line interface(when a geek types what he wants the computer to do)

Primary memory is closest to the CPU,which is RAM/ROM. Secondary storage is the hardware
