Networking Fundamentals Quiz

A technique used to divide a large network into smaller, more manageable subnets, improving network efficiency and security.

A smaller network within a larger network, identified by a unique subnet mask.

A 32-bit number that defines the network and host portions of an IP address.

A shorthand notation for IP addresses and subnet masks, using a single slash and the number of bits used for the network portion.

A set of tools used to analyze network traffic and identify potential problems or security threats.

Software that captures and analyzes network packets, providing insights into network activity.

A powerful command-line network sniffer in Linux, allowing for detailed packet analysis.

A popular GUI-based network analyzer, offering extensive filtering and analysis capabilities.

The process of borrowing bits from the host portion of an IP address to create smaller subnets.

A command-line tool used to determine if a host or server is online. It sends packets to a target IP address or domain name and awaits a response.

A command-line tool used in Linux and other Unix-like systems to display network interfaces and their associated settings.

Sub-netting is a technique used to divide a larger network into smaller, more manageable subnets. This allows for more efficient use of IP addresses and resources.

Sub-netting utilizes bits reserved for hosts within a network to expand the network ID, thereby enabling creation of networks of varying sizes.

A network mask is a binary mask that is applied to an IP address to identify whether two IP addresses belong to the same subnet. It determines which bits represent the network ID and which represent the host ID.

In CIDR notation, an IP address and its associated network mask are combined using a slash (/) followed by a decimal number representing the number of bits in the network mask. For instance, 192.168.1.0/24 indicates a network mask with 24 bits.

The network mask, also known as the subnet mask, is a 32-bit structure that distinguishes between network ID and host ID bits. A bit set to '1' signifies a network bit, while a '0' indicates a host bit.

By dividing a network into smaller subnets, organizations can create diverse physical networks and broadcast domains, thus minimizing network congestion and enhancing performance.

A Class A network typically has an 8-bit network ID, a Class B network has a standard 16-bit network ID, and a Class C network has a standard 24-bit network ID. Sub-netting allows for the creation of network IDs of any size.

Sub-netting helps network administrators use the 32-bit IPv4 address space more effectively and create networks with more realistic host numbers. It offers a flexible way to determine which part of the IP address represents the network ID and which represents the host IP.
