The number of bytes that will be sent or transmitted next is; 1620 bytes
How to find the number of bytes?We are given that:
The file size = 100 KB
The payload size = 100 bytes
The negotiated window size = 300 bytes.
This tells us that the sliding window can only accommodate a maximum number of 300/100 = 3 payloads
The sender receives an ACK 1500 from the receiver.
Total byte of the file is :
1000 KB = 1024000 bytes
The TCP header requires 20 bytes and IPV4 header requires 20 bytes.
Total TCP/IP header is composed of 40 bytes.
Sender receives an ACK 1500 from the receiver and as such the overhead which represents the bytes that will be sent next is;
1500 + (3 * 40)
= 1500 + 120
= 1620 bytes

listen to exam instructions amber, a network administrator, is conducting voip training for other it team members. melanie, a new team member, is confused about the difference between latency and jitter. what is the best way to explain the difference?
The best way to explain the difference is ''Jitter is the up and down variation in latency''.
Explain the difference between latency and jitter ?The main difference between jitter and latency is that jitter is defined as a shift in the amount of latency, whereas latency is defined as a delay caused by the network. It's crucial to frequently check jitter and delay since they have a detrimental effect on network performance.Jitter should ideally be less than 30ms. Network latency shouldn't exceed 150 ms one-way, and packet loss shouldn't be more than 1%.In a nutshell, jitter is an unintentional increase in latency or ping rate. When the rate fluctuates, it shakes the signal and increases the ping rate or latency on the way to and from the server, slowing down signal transmission and possibly leading to data loss. This is known as jitter.Learn more about latency and jitter refer to :
