alamvõrkude

Alamvõrkude, often translated as subnetting, is a process in computer networking that involves dividing a larger network into smaller, more manageable segments. This division is achieved by reallocating bits from the host portion of an IP address to the network portion. The primary purpose of subnetting is to improve network performance and security by reducing the size of broadcast domains and allowing for more granular control over network traffic.

Subnetting can lead to more efficient use of IP address space. By creating smaller subnets, organizations can avoid allocating large blocks of IP addresses that might go unused. It also enhances network security by isolating different segments of the network. For instance, sensitive servers might be placed on a separate subnet, with stricter access controls applied to that segment.

Furthermore, subnetting can improve network performance by reducing broadcast traffic. In a large network, broadcast messages are sent to all devices, which can consume significant bandwidth. Subnetting limits the scope of these broadcasts to within their respective subnets, thus reducing overall network congestion. The process of subnetting involves understanding IP addressing, subnet masks, and network calculations.
