Cyber Security: Networking Knowledge Flashcards

What is subnetting?
Subnetting is a technique used in computer networking to divide a large network into smaller, more manageable sub-networks, or “subnets.”
Why does subnetting enhances network performance and security?
Subnetting enhances network performance and security by reducing broadcast traffic and enabling better control over IP address allocation
Why does each subnet have its own range of IP addresses?
Each subnet has its own range of IP addresses, which allows network administrators to optimize network traffic and reduce congestion (Stauung, Überlastung) by isolating different sections of a network.
In how many and which parts is an IP address in subnetting split?
In subnetting, an IP address is split into two parts: the network portion and the host portion
What does the network portion of the IP address in subnetting?
The network portion identifies the overall network.
What does the host portion of the IP address in subnetting?
The host portion identifies individual devices within that network.
What does the subnet masks define in context of the IP address?
Subnet masks are used to define how much of the IP address belongs to the network and how much is reserved for hosts.
What is the advantage for administrators by adjusting the subnet mask?
By adjusting the subnet mask, administrators can create multiple subnets from a single network, with each subnet having a limited number of devices.
Why is subnetting particularly useful for large organizations?
Subnetting is particularly useful for large organizations, allowing them to efficiently manage IP addresses, improve security by segmenting different parts of the network, and control traffic flow by minimizing unnecessary data transmissions between segments.
