So, who's doing this paper?
Also, how do you go about answering the longer questions in the second section? Not the 12 mark essay ones, those are simple; I'm more interested in the 4-6 markers.
Any tips?

I'm doing it, though I'm not revising because I need something like 70/120 to get an A* because of my controlled assessments, which seems ridiculous but I'm not complaining.

The 4-6 markers can be tricky as they're often an obscure topic, or they want you to say a really specific thing. Not sure what advice I'd give, I guess just make sure you spell out everything no matter how obvious you think it is.

I'm in the same boat, my CA's were quite good, but I need around 86. I can get an A* without revising easily, but I hate those medium sized answer questions...

The 4-6 markers are easy. You just need to display to them that you're knowledgeable in a particular area. That means putting in enough detail and a few points.

You mentioned 12 markers are easy, I struggle a lot with them. Any tips?

Can you or somebody else help me please?

I got 110/120 in one CA (A*)
And the other one I got a high A* but don't know the UMS, lets pretend it was 110 too

So what do I need to get to get an A* overall?

Hi,
Was wondering if anyone knows anything about the 12 mark questions to get into the top bands or has any that they've completed that they can put up where they've got like full marks?

Please let me know, this is where I lose all my marks, I'm predicted A* and don't want to stupidly lose marks and not get this.

Thanks

I can't say for sure, so don't take this as fact.
But I do know I got about 90% on each Controlled Assessment, and as a result I need around 70/120 on the exam for an A* overall.

Those numbers may be out, so don't read to much into this, but I'd expect you'll need a similar amount to me to get an A* overall.

Yeah I got around 92% for one, the other I only know it is a high a*

Thanks!
Don't worry, I'm not using it as a fact, I was just curious to see how many marks I have to lose approximately before I drop a boundary

Complete GCSE ICT Notes

Data

  • Bit- each individual ‘1’ or ‘0’ is a bit-short for binary digit.
  • Byte- 8 bits are a byte.
  • Kilobyte-is 1000 bytes (1024)
  • Megabyte-is 1,000,000 bytes
  • Gigabyte-is 1,000,000,000 bytes
  • Each character on keyboard-8 bit



[edit]Computer systems v Manual systems

  • Benefits of computer system:
  • Takes up less space
  • Searching is very quick
  • More than one person can access the same data form their network PC.
  • The data stays in the computers memory
  • Fewer staff are needed to look after a computer system
  • Reports can be generated very quickly-automated




  • Problems of a computer system:
  • Setting up is very expensive
  • Computer systems need people to maintain them
  • POWER CUTS!
  • It is easy to hack into a computer system.



[edit]Types of computer

  • Mainframes-biggest
  • They are the most powerful
  • They are very large
  • VERY expensive
  • They are used in BIG businesses-banks, insurance companies.




  • Minicomputers-middle
  • Less powerful than mainframe but more powerful than micros


  • Microcomputers-most common-usually called PC’s.
  • Are designed to stand alone
  • Much less powerful than mainframes.



[edit]Networks-LANS AND WANS

  • Local area network-LAN-small-offices and schools.
  • Wide area network-WAN-large-link together different places.




  • Advantage of using networks-peripherals such as printers can be shared amongst several users.
  • Software can be shared amongst several users.
  • Communication across network is fast + cheap




  • Disadvantage of using networks-cabling can be expensive to install and replace
  • A fault with the server will prevent the whole network from working
  • Security measures are needed to restrict access to network
  • WANS are vulnerable to hackers and viruses.



[edit]'Networks-security

  • SERIAL NUMBERS
  • ALARMS
  • DOORS
  • FIRE PROTECTION
  • LOCK
  • AVOID
  • BLINDS




  • JUST REMEMBER SADFLAB


  • Passwords-should be changed frequently.
  • Backup-and files should be kept secure-in locked fireproof rooms.



[edit]Input devices

  • Keyboards
  • Mouses-touchpad, tracker balls.
  • Graphics pads make drawing easier and more accurate.
  • Joystick
  • Scanner
  • OCR scanners-read text
  • MICR-magnetic ink character recognition-cheques
  • OMR-optical mark recognition-registers-read lines in boxes.
  • Credit cards have a magnetic stripe on the back-carries info so the computer can identify the customer.

[edit]The CPU

  • The control unit makes the system work-CU
  • It controls all hardware attached to the system.
  • It controls the output and input of data
  • It controls the flow of data within the CPU




  • The ALU is where the processing happens-Arithmetic and logic unit.
  • Arithmetic part-does calculations!
  • Logic part-makes decisions like whether a number is bigger than –5.




  • The IAS is where active data is stored.
  • IAS-immediate access store



[edit]Output devices-PRINTERS

  • Dot matrix
  • Laser
  • Inkjet




  • Advantage of dot matrix-cheap and low operating costs.
  • Disadvantage of dot matrix-low res, slow, noisy.




  • Advantage of laser-high res, very fast
  • Disadvantage of laser-expensive.




  • Advantage of inkjet- good res, cheap
  • Disadvantage of inkjet- slow (ish), expensive to run



[edit]Data storage-ROM and RAM

  • RAM is temporary-random access memory
  • It stores data as electric signals.
  • If the power is cut or electricity fails everything in RAM-LOST!
  • ROM is permanent-Read-only memory
  • ROM however is not a backing storage on hard disk.



[edit]Backing storage

  • Hard disk-main internal storage.
  • Large capacity-range from 20gb to 100gb!
  • Floppy disk-3.5 inch
  • 1.44 mb-very small capacity
  • Magnetic tape-used to backup large amounts of data-cheap as well!
  • Access time is slow because it has to run through whole disc to find something.
  • Optical disks have fast access time.
  • CD-ROMS-oldest type-650mb
  • CD-R’s-sold as blanks-data can be written only once to it.
  • CD-RW’s-most popular. RW stands for read and write.
  • DVD-17 gb
  • ZIP disks-larger, thicker-100mb



[edit]Operating systems

  1. Enable applications to run
  2. Enables software to communicate with systems hardware
  3. It manages system resources
  4. Monitors performance of system
  5. Prompts error messages.


  • Multi tasking means an OS can run more than one program at a time
  • Basic systems that are not multi tasking are called single program mode OS’s.



[edit]User interfaces

  • Can be command driven-blank screen and commands and code used.
  • Can be menu driven- headings and menus
  • Most common is GUI-graphical user interface-combines menu driven and icons-
  • GUI’s are known as WIMPS-windows, icons, menus, pointers



[edit]Data capture

  • Data capture turns info into data
  • Automatic data capture-is fast and accurate
  • BUT manual data capture- is necessary sometimes, and it’s cheaper!



[edit]Data validation and verification

  • Validation-4 checks
  • Range check-checks data is in specified range
  • Presence check-makes sure data is present
  • Check digit-check that numerical data is accurate
  • Data type-checks that text is not where numbers are meant to be.
  • Verification-2 checks
  • Proof reading-read it and make sure that its accurate
  • Double-entry-data entered twice and compared.


  • Validation problems- mistakes may be allowed if carried out wrong and only makes sure that data is right type-NOT ACCURATE.




  • Verification problems-double entry is time consuming-expensive and proof reading is time consuming and does not eliminate human error.

[edit]Data processing

  • Real time processing does it instantly
  • Batch processing-all in one go
  • Transaction processing-one off specials
  • Interactive processing-talk to the computer



[edit]Access to data

  • Serial access-records are stored one after another in creation order
  • Sequential access-records are stored one after another acc. to sensible order
  • Direct access-can go to record directly



[edit]Implementation and evaluation

  • 3 types of implementation-
  • Direct-straight away and old system goes down but bugs not picked up in testing-bad news!
  • Phased-different parts are introduced one at a time
  • Old system is kept running


  • Parallel-new system is introduced in one go BUT old system stays
  • New system can be tested quickly but all tasks need to be done twice.
  • Evaluation just checks that the system meets all objectives




  • DTP SOFTWARE-is good because it creates pro. Looking documents and the layout can be changed more easily than word processors and the user can control the number of pages more easily than a word processor



[edit]INTERNET

  • The Internet is basically a very big WAN.
  • To connect you need a PC connected to a normal telephone line and a modem
  • You use your modem to dial up a computer that is owned by an ISP
  • You need 2 pieces of software- email client and web browser.
  • Internet has 2 main parts-WWW (world wide web) and email.
  • Speed of access depends on 3 things-
  • Modem speed-either 28kbps or 56kbps
  • Telephone line-either ISDN or ADSL
  • Volume of traffic-more people using the Internet, the slower the speed of access.




  • Http-hypertext transfers protocol-language that web uses.








  • Cgpbooks-domain name



[edit]Health and safety

  • RSI- repetitive strain injury-aches pains and muscle or tendon damage

Spending too long in front of a VDU can cause eyestrain and headaches. Circulation and fitness and back problems result from sitting all day in front of a computer



  • Solutions-
    • Take regular breaks, look away from screen walk around and exercise fingers
    • Use correct equipment- a chair with a backrest, a keyboard making it easier to type without straining
    • Good background lighting, good screens and a screen filter to reduce VDU glare.

You mentioned 12 markers are easy, I struggle a lot with them. Any tips?
When I answer them, I tend to think of pros and cons. Like the june 2012 asked about the impact of communications and entertainment tech on society. I remember splitting the two, and thinking holistically.
So for entertainment, I wrote down all the technology associated with entertainment, like TV, Music, Movies and Games. From there, I think of pros and cons one or two for each,if possible. I try to balance the number of pros and cons for that aspect.
TV-people are able to record programmes, makes it more flexible. Piracy
Music-Piracy, and digital use has led to decline in CD sales, but digital is easier to store etc.
Film- Rise of Netflix or equivalent, making film more accessible. Piracy
Games- People can play online easily with the rise of PSN/Xbox live.

I'd try to keep the number of impacts balanced for the entire question. I also would try to evaluate how big an impact each of the impacts have actually had, so piracy for film and music is big, but not as big for games and tv, although it is still there.
At the end, I'd summarize with a conclusion.
Hope this helps..

I've done zero revision for this, my controlled assessment was good (I don't know how good exactly) but my teacher said I need a good exam to get an A*. I sat it in January and got a medium A, so I was wondering if anyone could help me out with the exam technique? I'm proficient and knowledgeable about ICT in general so I think it was my style of answering that let me down.
