Understanding Computer Networks

What is the purpose of network protocols?

• To provide power to devices

• To increase the speed of the internet

• To manage hardware components

• The purpose of network protocols is to facilitate communication and data exchange between devices in a network.

Name three common network topologies.

• Mesh

• Star, Ring, Bus

• Hybrid

• Tree

What does IP stand for in networking?

• Internet Protocol

• Internal Protocol

• Interconnected Path

• Internet Provider

What is the difference between IPv4 and IPv6?

• IPv4 uses hexadecimal addresses; IPv6 uses decimal addresses.

• IPv4 has a 32-bit address space; IPv6 has a 128-bit address space.

• IPv4 is faster than IPv6 due to its smaller address size.

• IPv4 supports unlimited devices; IPv6 has a limited address space.

What device is used to connect multiple devices in a network?

• Router

• Switch

• Modem

• Access Point

Explain the function of a router in a network.

• A router amplifies signals to boost network speed.

• A router provides power to connected devices.

• A router is used to store data permanently in a network.

• A router functions to connect different networks and route data packets between them.

What is a subnet mask?

• A subnet mask is a type of firewall.

• A subnet mask is a physical device for networking.

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

• A subnet mask is used for data encryption.

Describe the star topology in networking.

• In a star topology, devices communicate directly with each other without a central hub.

• A star topology connects devices in a linear fashion.

• A star topology is characterized by a ring of interconnected devices.

• A star topology is a network configuration where all devices are connected to a central hub or switch.

What is the role of a switch in a network?

• A switch stores data permanently for backup purposes.

• A switch is used to connect to the internet directly.

• A switch amplifies signals in a network.

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

How is an IP address structured?

• An IP address is always 32 bits long.

• An IP address is a single number.

• An IP address consists of only letters.

• An IP address is structured as either IPv4 (e.g., 192.168.1.1) or IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
