In this case, there are 251 IP addresses available. They are unique addresses for the Internet Protocol.
<h3>What is an IP address?</h3>
An Internet Protocol (IP) address is a unique address on Internet, which is used to indicate a local network.
The term 'Internet Protocol' indicates the principles associated with the format of the data used by the local network.
An Internet Protocol address is always denoted by a set of numerical tags that indicate the local network.

D. Anything is possible if you put your mind to it and the knowledge and patience. I hope this helped :D
There are various connectivity technologies that we use to connect. They are Ethernet, Internet (Wireless Connection), Bluetooth, Wi-Fi and Cellular.
Explanation:
- Ethernet is the direct connection among the devices that are located close to each other in a building. This is used for small scale enterprises.
- Wi-Fi lets wireless connections among multiple devices without any physical connection. And it is most extensively used in most of the corporate companies.
- Bluetooth is used to transfer the data from one device to the other when they are near.
- Cellular is used to connect people across the globe. And it is used widely in every enterprises.
Answer:
A) 2.56 ms
B) 128 μs
Explanation:
Time for Bus cycles = 500 ns
Transfer of bus control = 250 ns
I/0 device data transfer rate = 50 KB/s
Data are transferred at : 1 byte at a time
A) Determine how long the device tie up the bus when transferring a block of 128 bytes
Block size to be transferred = 128 bytes
Bandwidth = 50 KB/s
data transfer = (Block size ) / ( Bandwidth)
= ( 128 * 8 ) / ( 50 * 10^3 * 8 )
= ( 1024 ) / ( 50 * 10^3 * 8 )
= 2.56 ms
To determine the actual transfer time we have to add up the transfer time for the bus control in both directions :
2.56 ms + 500 ns = 2.56 ms. this is because 500 ns is not a significant value
B) cycle stealing mode
In this mode each byte is transferred at a time and The total transfer time needed for the bus control in both directions will be double the total time i.e 2 * 500 ns = 1000 ns. because additional control time of 250 ns is required at both ends
since 1 byte is transferred at a time , 1 byte will be transferred in 1 μs
128 bytes = 128 * 1 μs = 128 μs
