Section 6

Hacking: The unauthorized access of data. people do this to make money from the data. Having a firewall will protect you from hackers as long as it has approiate security(ie Password)

Virus:Its a program/software that corrupts a system and/or the data. It does no good for anybody at all. Anti virus scans the computer for known files with viruses.However it still allows viruses onto your computer.It gets rid of them once you've  scanned the computer using todays list.

Employment: Computer/roots= unemployment. They're more efficent, faster and capable of doing things compared to Humans. The lack of workers with approiate IT skills menas there must be

Section 4

What  is a router: router goes to isp first.
dividing two bits of information up and passes information thats goin around one network to another keeping traffic separate.
doesnt have to go on internet
every router gets number
if sending something to something to some in own house doesnt need the internet
router control traffic
two setting internal eg inhouse, external if message is not for that person in that house.
tr ansfering thhings between your house withut using internet.


WIFI:
Tramsferring data between devices without the need for physical connection or wiring


 Bluetooth: 
is used by mobile devices for transferring smaller files
it is slower than wifi
bluetooth creates its own network and is an agreement between two devices wear is wifi is with multilple devices


How to set up a network:
to set a network with the internet you need a isp they will provide you with a router browser
IRB


ISP: Internet Service Provider eg: telecom, orcon
                                                                                                                                                                     


 advantages-communication, transfer of files, resources, share storage, common (all similar)
    disadvantages-virus', malware, hackers, loss of resource, loss of connection

 id's and passwords are used to divide personal files by accounts, authorize different access
    home directory=personal area of network


                                                                                                                                                                   


Faxes: hard copy to hard copy and legal.
Not secure as it could be unknown who picks up the fax
is also a delay- unknown that it could be there and could sit there for days


Email: Blind copy, 


-CC not for you but could be of intrest


Tele/video calling- Multiple people so that you can confrence and discuss something meaning you don't have to get on a plane just for a meeting.
tele - phone
video-video


local area network (LAN) - a network on one site 
(WAN) - two sites are permately linked


Differnce = one vs two sites
also to create a lan you need switches, hubs, bridges
to create a wireless lan need an access point thats linked on to the lan.
to create a WAN you a need a rotuer on eitehr end you also need an external internet line.


Intranet- web technoolgy being used inside your business, being more secure and people are more familar interface


Internet-providing services sharing information and advertising


HUB- is a confused nox , 
bridge - is a link between two parts of a LAN
, used to orginize the LAN to maximise the sending signal
Switches- Manages the traffic going from a specific port to another

Student privacy

-We want more Disclosure about our personal life

-Desprate for attention

-We dont care who reads our posts, we just Disclosure

-There is no force on earth from keeping teens from looking at something in the internet

How do we create a market for Facebook

when internet is blocked it limits the kids form for themselves.

Makes kids use proxies and makes it harder for the kids to use the internet propely

Trains kids to believe that survilence on the internet is a bad thing and privacy is a bad thing

Slows them thinking bout there privacy

Teach kids to incript and jailbreak, and teach them to portect and use privacy.

Teach how to bust sensor wall

Teach how to spoof every form

We need to accept that someone needs to know what you are doing

Feedback

Must be as close to the attempt as possible. You want to do better immediately as oppose to a week later.
Games are popular because the result of your action is shown to you as you play.

back storage at kc

• Fixed hard discs- Used in every computer in the school
• Portable hard discs- Used to store large files
• Magnetic tape- Uses serial access for reading and writing.  Used for backups of file servers for computer networks. Optical backing storage media such as CDs and DVD and is quite cheap for backing up files at King's.
• Optical backing storage media such as CDs and DVD-CDs tend to be used for large files (but smaller than 1Gb) which are too big for a floppy disc to hold such as music and general animation.  DVDs are used to hold very large files (several Gb) such as films at school.
• CD ROM/DVD ROM-Applications which require the prevention of deletion of data, accidental or otherwise for students.
• CD R/DVD- Applications which require a single burning of data, e.g. CDs Z recording of music downloads from the internet, recording of music from MP3 format, recording of data for archiving or backup purposes at King's.
• CD RW/DVD RW-Applications which require the updating of information and ability to record over old data at King's.
• DVD RAM- Same properties as DVD RW but quicker access and data can be overwritten more easily. 
• Blu-ray-Capacities of 25Gb, 50Gb and 100 Gb.  Used for storing films (movies). 25Gb equates to 2 hrs HDTV, 13hrs standard definition TV
• Solid state backing storage-Smallest form of memory, used as removable storage at school.  More robust than other forms of storage. 
• Memory sticks/Pen drive-Used at Kings to transport small files conveniently.
• Flash memory cards-Used in digital cameras, palmtops, mobile phones, MP3 players at Kings

Cheers Sheets for this information

BAcking storage ( class work)

DVD would be used at school over Blu-ray because blu- ray players are more expensive. Although there quailty of 25-100 Gb would be good it is an unessicarry want that we simply do not need. A simple DVD player would do the job just fine and is easier to access as they are built into Students and teachers Laptops.
Blu-ray players may be needed in some subjetcs like Media Studies where all they do is watch and anaylse movies, so this could be useful for them.

Steps for Access

Step one: Open Access
Step two: Start blank database and name it J08Database
Step three: Open text file csv
Step four: Press next
Step five: keep as delimited
Step six: Tick first row contains fields name, and make sure comma is ticked and press next
Step seven: Press next
Step eight: tick primary key and press next
Step nine: Press finish and close

Step ten: once pressing finish a box will appear, never ever tick it

IGCSE Theory Section 3

Section 3: Storage devices and media
Candidates should be able to:
(a)  describe common backing storage media (including magnetic tapes, hard discs, all forms of CD and
DVD, memory sticks, flash memory) and their associated devices
(b)  identify typical uses of the storage media, including types of access (e.g. serial/sequential, direct/
random) and access speeds

• Fixed hard discs Used to store operating systems, software and working data.  Any application which requires very fast access to data for both reading and writing to.  Not for applications which need portability.  Used for online and real time processes requiring direct access.  Used in file servers for computer networks
• Portable hard discs Used to store very large files which need transporting from one computer to another and price is not an issue.  More expensive than other forms of removable media
• Magnetic tapes Any application which requires extremely large storage capacity and speed of access is not an issue.  Uses serial access for reading and writing.  Used for backups of file servers for computer networks.  Used in a variety of batch processing applications such as reading of bank cheques, payroll processing and general stock control
• Optical backing storage media such as CDs and DVDs CDs tend to be used for large files (but smaller than 1Gb) which are too big for a floppy disc to hold such as music and general animation.  DVDs are used to hold very large files (several Gb) such as films.  Both CDs and DVDs are portable i.e. they can be transported from one computer to another.  Both can be used to store computer data
• CD ROM/DVD ROM Applications which require the prevention of deletion of data, accidental or otherwise.  CDs used by software companies for distributing software programs and data; by music companies for distributing music albums and by book publishers for distributing encyclopaedias, reference books etc.  DVDs used by film distributors
• CD R/DVD R Applications which require a single eburningf of data, e.g. CDs Z recording of music downloads from the internet, recording of music from MP3 format, recording of data for archiving or backup purposes.  
• DVDs Z recording of films and television programs
• CD RW/DVD RW Applications which require the updating of information and ability to record over old data.  Not suitable for music recording but is very useful for keeping generations of files.  DVDs have between five and ten times the capacity of CDs
• DVD RAM Same properties as DVD RW but quicker access and data can be overwritten more easily.  Similar to floppies in nature but has 3000Z6000 times more storage and uses optical technology
• Blu-ray Capacities of 25Gb, 50Gb and 100 Gb.  Used for storing films (movies). 25Gb equates to 2 hrs HDTV, 13hrs standard definition TV.  It is possible to playback video on a disc while simultaneously recording HD video.  (Will be) used for storage of PC data
• Solid state backing storage Smallest form of memory, used as removable storage.  More robust than other forms of storage.  More expensive than other forms, but can be easily written to and updated
• Memory sticks/Pen drives Can store up to many Gb.  Used to transport files and backup data from computer to computer
• Flash memory cards Used in digital cameras, palmtops, mobile phones, MP3 players

IGCSE Syllabus Section 2

Candidates should be able to:
(a)  identify the following input devices:
   keyboards, numeric keypads, pointing devices (including mouse, touch pad and tracker ball), remote
controls, joysticks, touch screens, magnetic stripe readers, chip readers, PIN pads, scanners, digital
cameras, microphones, sensors, graphics tablet, MICR, OMR, OCR, barcode readers, video cameras,
web cams, light pens
(b) identify suitable uses of the input devices stating the advantages and disadvantages of each:

• Numeric keypad Applications where only numeric data is to be entered.  Inserting personal identification number (PIN) for Chip and PIN credit/debit cards, or when using an ATM machine to withdraw money or check a bank balance
• Pointing devices Z all All applications which require selection from a graphical user interface.  For example: the selection of data from a set list or menu
• Trackerball For use by people with limited motor skills e.g. young children or people with disabilities
• Magnetic stripe readers At POS terminals, ATMs and in security applications
• Chip readers and PIN pads Payment cards, ID cards, door control systems, public transport tickets
• Optical Mark Reader Inputting pencil marks on a form such as a school register, candidate exam answers, any application involving input of a choice of options 
• Optical Character Reader Inputting text to a computer ready for processing by another software package such as word processors, spreadsheets, databases etc.
• Light pen Where desktop space is limited, it is used instead of a mouse or for drawing applications where a graphics tablet might be too big, for more information : http://en.wikipedia.org/wiki/Light_pen
• CRT monitor Applications where space is not a problem.  Applications where more than one user may need to view screen simultaneously such as in design use, e.g. when several designers may need to offer suggestions on a prototype
• TFT monitor Applications where space is limited such as small offices.  Applications where only one person needs to view the screen such as individual workstations
• Laser printer Applications which require low noise and low chemical emissions, e.g. most networked systems.  Applications which require rapid, high quality and high volumes of output, e.g. most offices and schools
• Inkjet printer Applications which require portability and low volume output, where changing cartridges is not an issue e.g. small offices and stand alone systems.  Applications which require very high quality output and where speed is not an issue, e.g. digital camera applications
• Dot matrix printer Applications where noise is not an issue and copies have to be made, e.g. industrial environments (multipart forms, continuous stationery, labels etc.), car sales and repair companies, manufacturing sites
• Graph plotter CAD applications, particularly where large printouts are required such as A0

History 3/3/11

Today in history we learnt a few new and intrestings things.

Our focus at the moment is the Treaty of Versailles and The League of Nations.
We are learning the facts and terms of these two things.

Treaty of Versailles Facts

- Was wrote after the Armistice of WWI in 1918
- Involved The Big three Who were Cleamaceau ( france) Wilson (USA) and Lyold-Geogre ( Britain)
- Was signed in June 1919

Terms

- Lost of 13% of German land which resulted in the lost of 7 million people to other countries who were in that border.
- Some of that land rich in raw materials
- Germany split in half by the polish corridor.( a strectch of ex German land given to poland)
- German army to be reduced to 100,00 men, 6 battleships, no Airforce, submarines, tanks and the demilitariztion of the rhineland.
- 6.6 billion pounds to be paid in repariations to the Victors.
- Article 231 in the treaty. Germany were to take full responsiblity in staring the war. Also known as the War guilt Clause.

These are just some quick facts on The Treaty of Versailles.

Twitter

In what ways did twitter help people in Christchurch?

Twitter has helped the people of Christchurch in many ways. The main example of this is when people were tweeting for help when they were under the rubble. They tweet that they are alive and there location so that they can be rescued. Also It helps people who are missing people to try and help find there missing or the missing to tell there relatives where they are.

Quote examples of tweets that show the different uses?

An example is when Someone tweeted that they had hundreds of bottled water in there factory once this tweet was out, people flocked to the factory to collect these bottles of water because Christchurch had no running fresh clean water. Another is  when A man had lots of meat in his frezzer, but because of the power cut he needed to get rid of it. So he tweeted for everyoen to come around and he had a BBQ with evryone who saw he tweet because of course there is a lack of food in Christchurch at this time.

How do people use the Twitter functions?

The functions on twitter are easy to use and very accesiable because you don’t even need an account it is now a very good search engine, because its efficient and real time. Instead of texting one person on a phome tweeting allows the whole world to see your tweet. Also there is no need to sign up which can be very helpful quick to use.

Why is twitter good in a crisis?

It is good because it is a good way of communicating with others for help or loved ones for comfort. Twitter can never be shutdown therefore it will always be  available compared with txing. It also does not cost to use so it would help those who would need urgent help because obvisouly they wouldn’t have money. It could also be used to orginise meetings and events. Also it can help raise money for the people involed in the crisis.

Compare it with Facebook?

Twitter does not sell your private information like facebook so your safe there. Also when tweeting the whole world can see it while with Facebook only friends can see it. Also Twitter you can use it while not having to sign up like Facebook does. Facebook also does not having regular tweeting like Twitter.

Excel

Save as …. Save As Type … excel workbook

=lookup is look up function

All forumlas have brackets.

Example of what we are doing =lookup(THIS, HERE)

Do not highlight titles when you highlight lists

Type name to replace number you must press enter otherwise it won't confirm

Always rember commas

Excel

These are required in the use of excel.

1. Import CSV- (comma separating values)

2. Absoulute and realative referances- A1 is cell referance.

Relative cell refernce is when it changes depending on where you paste it.

A aboslute reference is where its is absoluting always going to refer to that cell.

3. Named cells - makes reading cells easier

    Named ranges- naming a group of cells

4. Sum, average, maximum, minimum, integer, rounding, counting, if , lookup

5. perform searches using AND, OR , NOT, LIKE,  >,  < ,  = , >= , <=

  filtering searches like google.

6. Perform searches using wildcards

Software-utility software is used to change the system(control panel in system prefrences)
               A set of commands
              opperating sytem
              aplication
Hardware-the physical componets in a system

Input device eg keyboard, mouse

Cpu(central procssing unit)

Rom- read only memory, doesnt change.. rom stays permennant and Non volatile

Ram- random access memory, contiously changes, holds whats going on now

Hardive- secoundary storage( holds for days)

Output- eg printers ( four catergories)

Interface- GUI ( graphical use interface)

WIMPS- Windows, icons, menus, pointers
