The dimension of usability that is being addressed by Beth is known as efficiency.
<h3>The dimension of usability.</h3>
In Usability Engineering, there are five (5) qualities of a usable product suggested by Jakob Nielsen and these include the following:
- Errors (low rate, easy to recover)
In this scenario, we can infer and logically deduce that the dimension of usability that is being addressed by Beth is known as efficiency because she's focused on identifying early-stage interface problems in software.

Answer:
the mouse is an optical mouse
Explanation:
The user's mouse does not have a ball to be cleaned when it does not work right because he or she is using an optical mouse. This type of mouse does not use the old-ball-system, but rather uses a light source, which usually consist of a light detector and a light-emitting diode, and this set-up ensures that movement is detected relative to a surface and hence the cursor is moved too.
Answer:
5 seconds
Explanation:
Given that :
Message size = 16kb
Packet size = 2kb
Speed = 4kbps
Number of links = 3
The time taken is calculated using the formula :
[Number of packets + (Number of links - 1)] * (packet size / speed)
Number of packets = message size / packet size
Number of packets = 16kb / 2 kb = 8
Hence,
[Number of packets + (Number of links - 1)] * (packet size / speed)
(8 + (3 - 1)) * (2 / 4)
(8 + 2) * (1 /2)
10 * 1/2
= 5 seconds
