Answer:
<u>The total time elapsed from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B is </u><u>25.11 ms</u>
Explanation:
Host A first converts the analog signal to a digital 64kbps stream and then groups it into 56-byte packets. The time taken for this can be calculated as:
time taken 1= 
= (56 x 8) bits / 64 x 10³ bits/s
= 7 x 10⁻³s
time taken 1= 7 ms
The transmission rate of the packet from Host A to Host B is 4 Mbps. The time taken to transfer the packets can be calculated as:
time taken 2= (56 x 8) bits / 4 x 10⁶ bits/s
= 1.12 x 10⁻⁴ s
time taken 2= 112 μs
The propagation delay is 18 ms.
To calculate the total time elapsed, we need to add up all the time taken at each individual stage.
<u />
<u> = Time taken 1 + Time taken 2 + Propagation Delay</u>
= 7 ms + 112 μs + 18 ms
= 0.025112 s
= 25.11 ms
<span>C. Maintenance
is an important practice can help prevent hardware trouble. Maintenance involves operational and
functional checks, servicing, repairing or replacing if necessary. Maintenance has
two types which are </span>preventive
or scheduled maintenance and corrective maintenance. Inspecting, maintaining
and protecting a device, equipment or facilities before breaking down or other
problems occur it is called preventive while corrective is when it is repaired
or replaced after wear, malfunction or break down.
Answer:
its copyright has expired

Answer:
A mouse.
Explanation:
An input device can be defined as any device that is typically used for sending data to a computer system.
Generally, all of the output and input device of a computer are known as peripheral (external) devices and they provide data (informations) to the end users in various formats such as video, audio, texts, images etc.
Since input devices are peripheral (external) devices, they can be connected to the computer system wirelessly or through a wired-connection (cable).
Some examples of peripheral (external) devices are monitor, speakers, keyboard, printer, scanner, projector, mouse, etc.
A mouse is an input device that is designed and used to select specific menu options, drag and drop options and to draw something on screen.
