Network Issues and Communication

Network Issues

Network congestion happens when too many devices are connected to the network, slowing down data transmission speed.
Latency is the delay in transmitting or processing data, usually due to distance and network congestion.
Interruptions in the network caused by physical damage or power outages are known as network downtime.
Data corruption can occur during transmission, making the data unusable or incorrect at the receiving end.
Network security breaches can happen when unauthorised users gain access to the network, leading to potential data theft or corruption.
A hack is when someone breaks into a network or computer system to steal, change or destroy information.
Networks can be susceptible to malware, malicious software designed to harm or exploit any computing device or network.
An overload of network traffic can lead to a Denial of Service (DoS) attack, where the network becomes unavailable to its intended users.

Data packets are units of data broken down for efficient routing and transmission over the network.
TCP/IP is the primary protocol suite used on the internet, ensuring reliable transmission of data packets.
HTTP and HTTPS are protocols used for transmitting hypermedia over the internet safely.
Network protocols are established sets of rules that determine how data is transmitted and received in a network.
File Transfer Protocol (FTP) is used to transfer files from one host to another.
Simple Mail Transfer Protocol (SMTP) is used to send and receive email.
Instant Messaging (IM) allows for real-time direct text-based communication between two or more people.
Voice over Internet Protocol (VoIP) delivers voice communications and multimedia sessions over the Internet.

Troubleshooting is the process of diagnosing the source of a network problem.
Regular system updates help prevent many network issues by fixing known problems and improving system performance.
Installing a firewall prevents unauthorised access and blocks harmful software.
Encryption of data safeguards sensitive information during transmission.
To mitigate network congestion, a network traffic management system could be used to control the data traffic.
Regular backups can help keep data safe in case of a network problem.
User training and awareness programs can prevent network issues caused by human error.

Network issues can lead to a loss of productivity due to downtime.
They can cause a loss of data, which can have serious consequences for businesses.
Breach of customer trust can occur when personal or confidential data is compromised.
Financial losses can occur due to remedial costs and loss of business owing to damaged reputation.
