Understanding Computer Networks

What is a network topology?

• Network topology refers to the speed of data transmission.

• Network topology is the type of software used in networking.

• Network topology is the security measures implemented in a network.

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

Name three common types of network topologies.

• Tree

• Hybrid

• Star, Bus, Ring

• Mesh

What is the purpose of an IP address?

• To assign a name to a device for easier identification.

• To provide internet access to all devices on a network.

• To uniquely identify a device on a network and facilitate communication between devices.

• To encrypt data transmitted between devices.

How many bits are in an IPv4 address?

• 64 bits

• 128 bits

• 32 bits

• 16 bits

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 cannot.

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

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

Explain the concept of subnetting.

• Subnetting eliminates the need for IP addresses in a network.

• Subnetting is only used for wireless networks.

• Subnetting allows for the creation of smaller networks within a larger network, improving management and security.

• Subnetting is the process of merging multiple networks into one.

What is a subnet mask?

• A subnet mask is a physical device that connects networks.

• A subnet mask is used to encrypt data.

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

• A subnet mask is a type of firewall.

How does subnetting improve network performance?

• Subnetting reduces broadcast traffic and improves network efficiency.

• Subnetting increases the size of the network.

• Subnetting simplifies network hardware requirements.

• Subnetting eliminates the need for routers.

What are the main functions of network protocols?

• Network hardware manufacturing standards

• Data encryption and decryption

• User authentication and authorization

• The main functions of network protocols include data transmission, error detection and correction, connection establishment, flow control, and device identification.

Name two common network protocols and their purposes.

• TCP and HTTP

• SSH and SNMP

• FTP and SMTP

• IP and DNS
