Exploring Computer Networking Concepts

What is the primary purpose of a router?

• To provide internet access to a single device.

• To store data packets for later use.

• To forward data packets between networks.

• To connect devices within a single network.

Define the term 'IP address'.

• A method for encrypting data on a network.

• A type of software used for browsing the internet.

• A physical address of a computer in a local area network.

• An IP address is a unique numerical label assigned to each device on a network that uses the Internet Protocol for communication.

What is the difference between TCP and UDP?

• UDP guarantees delivery of packets while TCP does not.

• TCP is faster and connectionless; UDP is reliable and connection-oriented.

• TCP and UDP are both connection-oriented protocols.

• TCP is reliable and connection-oriented; UDP is faster and connectionless.

Explain what a subnet mask is.

• A subnet mask is used to encrypt data for secure transmission.

• A subnet mask is used to specify the network and host portions of an IP address.

• A subnet mask defines the maximum number of devices on a network.

• A subnet mask is a type of firewall that blocks unwanted traffic.

What does DNS stand for and what is its function?

• Domain Name Service

• Domain Naming System

• Dynamic Name System

• Domain Name System

What is the role of a switch in a network?

• A switch amplifies signals to extend network range.

• A switch connects devices in a network and forwards data to the correct destination based on MAC addresses.

• A switch is used to connect a network to the internet.

• A switch stores data permanently for future access.

Describe the concept of a VPN.

• A VPN is a type of antivirus software.

• A VPN is a hardware device that boosts internet speed.

• A VPN is a social media platform for sharing files.

• A VPN is a service that encrypts your internet connection and masks your IP address to protect your online activities.

What is the function of a firewall in networking?

• To store and manage user data securely.

• To provide a physical barrier between devices.

• To increase network speed by optimizing data flow.

• The function of a firewall in networking is to monitor and control network traffic to protect against unauthorized access and threats.

What is the difference between a public and a private IP address?

• Private IP addresses can be accessed from anywhere on the internet, while public IP addresses are restricted to local use.

• Public IP addresses are accessible over the internet, while private IP addresses are used within local networks and are not accessible from the internet.

• Public IP addresses are always static, while private IP addresses are always dynamic.

• Public IP addresses are used for local networks, while private IP addresses are accessible over the internet.

Explain the term 'bandwidth' in the context of networking.

• Bandwidth is the number of devices connected to a network.

• Bandwidth is the maximum data transfer rate of a network connection, measured in bits per second.

• Bandwidth is the amount of time a network connection is active.

• Bandwidth refers to the physical distance between network devices.
