Exploring Networks and Security

What is a network topology?

• The speed of a network connection

• The type of devices used in a network

• Network topology is the layout or structure of a network, including how devices are connected and communicate.

• The software used to manage a network

Name three common types of network topologies.

• Hybrid

• Tree

• Mesh

• Star, Bus, Ring

What is the main advantage of a star topology?

• Requires extensive cabling and hardware.

• Easy to manage and troubleshoot, with high reliability.

• Difficult to set up and maintain.

• Low performance under heavy load.

How does a bus topology work?

• A bus topology requires a central server to manage data traffic.

• A bus topology connects devices wirelessly without any cables.

• A bus topology uses multiple interconnected switches to route data.

• A bus topology connects all devices to a single central cable, allowing data to travel in both directions until it reaches the intended recipient.

What is network security?

• Network security is the practice of protecting computer networks from intrusions, attacks, and unauthorized access.

• Network security is the process of enhancing internet speed.

• Network security refers to the physical layout of a network.

• Network security is the practice of improving user interface design.

Why is network security important?

• To reduce the cost of network infrastructure.

• Network security is important to protect data and maintain the integrity and availability of network resources.

• To increase network speed and performance.

• To enhance user experience without any security measures.

What is a firewall in network security?

• A firewall is a network security system that monitors and controls traffic based on security rules.

• A firewall is a type of antivirus software.

• A firewall is a physical barrier that prevents unauthorized access.

• A firewall is a device that boosts internet speed.

What are some common threats to network security?

• Strong passwords

• Unauthorized access, malware, phishing attacks, denial of service (DoS) attacks, insider threats

• Regular software updates

• Firewall configurations

What does encryption do in network security?

• Encryption slows down network performance significantly.

• Encryption is used to increase the size of data files.

• Encryption secures data by converting it into a format that is unreadable without a decryption key.

• Encryption makes data more accessible to unauthorized users.

How can users protect their networks from unauthorized access?

• Share passwords with all users

• Implement strong passwords, enable firewalls, use encryption, update software regularly, and monitor the network.

• Disable all security software

• Use public Wi-Fi for all connections
