line 4
if salary < 30000
error missing ":"
solution
if salary < 30000:
line 6
tax = salary * 0.2
error is missing identifier for tax
solution add identifier for tax on line 3
tax = 0.0
line 11
error syntax
solution is move tax = salary * 0.4 + 6000 to the right
tax = salary * 0.4 + 6000
Answer:
All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.
A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision
Explanation:
Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.
CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.
Answer:
The answer to this question is given below in the explanation section
Explanation:
The correct answer is :
A reader needs to hear a word pronounced
A student needs to take notes about a text
Because, text to speech tools mostly used to hear the text written in some files such as reading text from pdf file etc, or word pronunciation. However other options are not right because, reading a difficult material does not make sense with reading it links to understanding.
However, speech to text can be used by the student to take notes while listening the text, but would be easy instead of taking notes and listening, it is easy to copy the text.
