Final answer:
All of the option. A lack of bandwidth can lead to QoS issues such as jitter, latency, packet loss, and congestion, affecting data transfer efficiency and quality.
Step-by-step explanation:
A lack of bandwidth on a network can lead to several Quality of Service (QoS) issues, including jitter, latency, packet loss, and congestion. Jitter refers to variations in packet timing during data transfer, which can impact the quality of real-time applications such as video conferencing. Latency is the delay between the sending and receiving of packets, and high latency can cause noticeable lags in communication. Packet loss happens when network congestion leads to packets being dropped, which can reduce the overall quality of the transmitted data. Lastly, congestion occurs when the network lacks sufficient bandwidth to handle all traffic efficiently, leading to the aforementioned issues of jitter, latency, and packet loss.
A lack of bandwidth can lead to several Quality of Service (QoS) issues. These include:
Jitter: Jitter refers to variations in packet delay, causing inconsistent voice or video quality during real-time communications.
Latency: Latency is the time delay between sender and receiver, resulting in slow response times in applications and web browsing.
Packet loss: Packet loss occurs when data packets are dropped during transmission, leading to missing or incomplete information and degraded performance.
These QoS issues can arise when the available bandwidth is insufficient to handle the amount of data being transferred. For example, if multiple users are streaming videos or downloading large files simultaneously on a network with limited bandwidth, it can cause congestion and impact overall network performance.
