Network Basics

What are the two main types of networks?

• Intranet and Extranet

• Ethernet and Token Ring

• WiFi and Bluetooth

• LAN and WAN

Explain the difference between LAN and WAN.

• LAN connects devices within a small area, while WAN connects devices over a large area.

• LAN connects devices over a large area, while WAN connects devices within a small area.

• LAN is used for wireless connections, while WAN is used for wired connections.

• LAN and WAN are the same and can be used interchangeably.

What is a network topology?

• A network topology is the layout pattern of interconnections between devices in a network.

• A network topology is a type of exotic fruit

• A network topology is a type of mathematical equation

• A network topology is the study of ancient geographical features

List and briefly explain the different types of network topologies.

• Triangle

• Pentagon

• Square

• Bus, star, ring, mesh, and hybrid

What is network security and why is it important?

• Network security is important for protecting sensitive information, preventing cyber attacks, and ensuring data privacy and integrity.

• Network security is only important for preventing physical break-ins and theft

• Network security is not important and does not affect sensitive information or data privacy

• Network security is important for increasing the speed and efficiency of data transfer

Name and describe three common network security threats.

• Spyware, ransomware, firewall

• Phishing, firewall, antivirus

• Malware, phishing, DDoS attacks

• Trojan horse, antivirus, encryption

What is a router and what is its function in a network?

• A router is a type of musical instrument used in traditional folk music

• A router is a type of power tool used for shaping wood

• A router is a networking device that forwards data packets between computer networks.

• A router is a type of software used for editing photos

Explain the role of a switch in a network.

• It filters out unwanted data based on IP addresses.

• It stores and manages the network configuration settings.

• It directs data to the appropriate destination based on MAC addresses.

• It amplifies the signal strength of the data packets.

What is a firewall and how does it protect a network?

• A firewall protects a network by monitoring and controlling incoming and outgoing network traffic based on predetermined security rules.

• A firewall protects a network by encrypting all incoming and outgoing network traffic

• A firewall is a type of antivirus software that scans the network for potential threats

• A firewall is a physical barrier that prevents any network traffic from entering or leaving the network

What is a modem and what is its purpose in a network?

• A modem is a device that compresses and decompresses signals to enable digital data to be transmitted over analog communication lines. Its purpose in a network is to reduce the amount of data being transmitted.

• A modem is a device that encrypts and decrypts signals to enable digital data to be transmitted over analog communication lines. Its purpose in a network is to provide security for data transmission.

• A modem is a device that amplifies and filters signals to enable digital data to be transmitted over analog communication lines. Its purpose in a network is to boost the speed of data transmission.

• A modem is a device that modulates and demodulates signals to enable digital data to be transmitted over analog communication lines. Its purpose in a network is to convert digital data from a computer into analog signals for transmission over a telephone line, and to convert incoming analog signals back into digital data for the computer to receive.
