4.1.4 Daar word gesê dat hierdie „App‟ „n Multidraadverwerking („multi-threading‟)-verwerkingstegniek gebruik. Verduidelik wat Multidraadverwerking is en gee „n voorbeeld. (3)

Multidraadverwerking is die vermoë van „n bedryfstelsel ✓om dit vir programme moontlik te maak om hulself in „n klomp take (threads) ✓te verdeel sodat daardie take tegelyk kan uitvoer asof hulle verskillende programme is.

Bv.: Die verdeling van „n woordverwerkers-program om spelling te kontroleer, drukwerk in die agtergrond te doen terwyl die gebruiker toevoer doen en afvoer op die skerm plaasvind. ✓

4.1.5 Name TWO other processing techniques AND explain when it will be used. (4)

Multitasking ✓ When different programs are active and the

OS splits the CPU time between the active programs and give each program a few fractions of a second of access time to the CPU so that it appears to run multiple programs at the same time. ✓

Multiprocessing ✓ When the CPU consists of more than one

physical CPU, then the OS divides the programs/threads/processes between more than one physical CPU. ✓

4.1.5 Noem TWEE ander verwerkingstegnieke EN verduidelik wanneer dit gebruik sal word. (4)

Multitaakverwerking: ✓ Wanneer „n rekenaar veelvuldige

programme tegelyk uitvoer. Die bedryfstelsel verdeel die SVE-tyd tussen die aktiewe programme en gee elkeen „n paar millisekondes toegangstyd tot die SVE. ✓

Multiverwerking: ✓ Die bedryfstelsel verdeel die programme,

drade of prosesse tussen verskillende verwerkers. ✓

made. ✓ Entering incorrect data in a program. Losing or misplacing portable storage

devices. ✓ Allowing other unauthorised users to get

access to data by not following basic security principles such as having a secure password and changing it on a regular basis. ✓

4.3.4 Give THREE reasons why social

networking sites are so prone to social engineering. (3)

The vast number of users of social networking websites on a daily basis creates a potentially vast „target market‟✓. An „artificial‟ level of trust that is developed as „friends‟ on social networking sites can be used to cause the user to give out information that they should not. ✓ Users often publish personal details such as their cellphone numbers or names of their pets which they may have used as their passwords etc. ✓

Die verkeerde data word in „n program ingevoer. ✓

Draagbare toestelle raak weg. ✓ Basiese sekuriteitsbeginsels – soos sterk

wagwoorde en gereelde verandering daarvan – word nie gebruik nie. ✓ (ongemagtigde gebruikers kry toegang tot die data).

4.3.4 Gee DRIE redes waarom sosiale netwerktuistes so vatbaar is vir sosiale manipulasie. (3)

Duisende sosiale webtuistes word elke dag deur miljoene gebruikers besoek, wat van die gebruikers sowel as hulle rekenaars ‟n groot „teikenmark‟ maak. ✓

‟n „Kunsmatige‟ vlak van vertroue bestaan tussen „vriende‟ op sosiale netwerktuistes en kan uitgebuit word sodat gebruikers vertroulike inligting verskaf. ✓

Gebruikers vertoon dikwels hul persoonlike inligting soos selfoonnommers en hulle troeteldiere se name wat hulle dalk as hul wagwoorde gebruik het! ✓
