1)Not sure about this one (it is kinda late here sorry :P)
2) All you need to know is that computers can't 'read' analogue data and can only read Digital. So if you want a computer to read data off of a sensor then you need a Analogue to Digital converter (usually a modem).
3)File consists of data, Record is a single structured data item in a table, Primary Key is a unique record (such as Bar Code or Civil ID Number) that is unique to each field.
4)Don't actually understand this one.
5)Web 2.0 is the name given to recent development of interactive websites, allows you to share info (Facebook, Notes) Interact (Chat comment) Collaborate (Create web pages) Create (Youtube vids is a good example)
Wikis are pages edited and allow people to collaborate information. Blogs are personal websites of people that post about various things (like war,fashion,games). Media upload sites are sites which allow you to upload and share Media such as videos or pictures (Youtube,Flickr). Social networking sites are sites which allow you to connect and interact with other people/friends, they allow you to share pictures videos and other (Facebook, Myspace)
6) Phishing is when some one is trying to gain personal information by acting as a official and stealing your information (an example of this is hotmail. You sometimes might get e-mails claiming your e-mail has been hacked and they require your info, once you send it they hack your e-mail). Pharming is when a hacker redirects a sites traffic to his own to gain either views or steal info, for example you open facebook and you go to a site which looks like it, you might think they updated it or something so you enter your info and get hacked. Spam is unwanted information, or e-mails etc.

By the way thx for the rep but it still says 0. Hmm glitch?
Any way I hope I helped, keep em coming!

Verification is when another person checks if the data entered had any mistakes, there is two ways to do this. Compare data on screen with that on paper or get two people to enter the same data.
Validation is when a computer checks if the information entered is valid. Examples include validating e-mail and password enters(i.e. if your e-mail username match's that of your password)

If you need anything else just ask

Heyy guys. In paper 1, there is a question

"The systems analyst will also design a medical staff record system. She will need to
produce a screen display which the hospital administrators could use to read details of
a member of staff.
 
 Design a suitable output format for displaying the details of one member of staff."

In the marking scheme, it says that it should "clearly" look like a computer output screen. What does a computer output screen look like?
