Answer:
<u>D. In DMA, interrupt is sent when the task is completed</u>
Explanation:
Note, the term Direct Memory Access simply refers to a computer feature that allows hardware subsystems to directly access the main system memory of a computer, without any the aid of the central processing unit (CPU).
It is a fact that while the transfer process is ongoing, an interrupt (interrupt signal) is not sent until when the task is completed.
Answer:
D. Crowdsourcing
Explanation:
Crowdsourcing can be defined as a collaborative process which typically involves completing a project (task) and solving a problem through a group of people (crowd) that are geographically dispersed over the internet.
Basically, crowdsourcing refers to an outsourcing technique which allows a project or task to be jointly completed by a group of people (crowd) such as volunteers or freelancers who are made to work remotely over the internet.
<em>In this scenario, an online music provider such as Pandora or Jango uses crowdsourcing for collaborative filtering, which helps define the list of songs available to listeners. </em>
Answer:
a) 255
b) 61602
c)
d)
Explanation:
You need to understand the decimal equivalent of hexadecimal numbers, <em>from 0 to 9 numbers are represented the same way, from 10 to 15 we use the alphabet, meaning 10 equals A in hexadecimal base, 11-B, 12-C, 13-D, 14-E, and 15-F.</em>
For your first exercise you'll enumerate the number's positions fromright to lef begining with 0:
a. F F
position 1 0
Now you'll multiply your hexadecimal number (using the decimal equivalent for your letters) for the base (16) elevated to the number of the position:
Finally, you'll add your results:
240+15=255
FF=255
b. F 0 A 2
position 3 2 1 0
F0A2=61602
c. F 1 0 0
position 3 2 1 0
0F100=61696
d. 1 0 0
position 2 1 0
100=256
