Computer and Network Techniques Pre-Test

What is the purpose of network protocols?

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

• To establish security protocols for data encryption.

• To manage hardware resources in a computer system.

• To define the physical layout of a network's infrastructure.

Name three common network protocols.

• SMTP

• HTTP, FTP, TCP

• POP3

• IMAP

What does IP stand for in networking?

• Internet Protocol

• Internet Provider

• Interconnected Protocol

• Internal Protocol

What is the difference between IPv4 and IPv6?

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

• IPv4 uses hexadecimal addresses, while IPv6 uses decimal addresses.

• IPv4 supports unlimited devices, while IPv6 is limited to 4 billion addresses.

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

How many bits are in an IPv4 address?

• 64 bits

• 128 bits

• 32 bits

• 16 bits

What is a subnet mask?

• 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 a type of firewall.

• A subnet mask is used to encrypt data.

Explain the concept of subnetting.

• Subnetting refers to the physical layout of network cables.

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

• Subnetting is a method for increasing the size of a network.

• Subnetting is the practice of dividing a network into smaller sub-networks to improve performance and security.

What is the purpose of a default gateway?

• The purpose of a default gateway is to route traffic from a local network to external networks.

• To connect multiple devices within the same local network.

• To provide a backup for local network devices.

• To assign IP addresses to devices on the network.

What is the range of a Class C IP address?

• 192.0.0.0 to 223.255.255.255

• 224.0.0.0 to 239.255.255.255

• 128.0.0.0 to 191.255.255.255

• 10.0.0.0 to 10.255.255.255

What is the function of DHCP in a network?

• To establish a physical connection between devices.

• The function of DHCP in a network is to automatically assign IP addresses to devices.

• To provide network security by filtering traffic.

• To manage network bandwidth and prioritize data packets.
