NETWORK SEGMENT Meaning and
Definition
-
A network segment refers to a distinct portion of a computer network that is logically or physically separated from the rest of the network. It is a division or segment of a larger network infrastructure that allows for more effective management and control of network resources.
In a logical sense, a network segment is created by implementing different network routing protocols or subnetting techniques to partition a larger network into smaller, more manageable segments. Each segment may have its own unique network address range, enabling separate configuration and administration. This isolation allows for better control of network traffic flow, security, and troubleshooting. Network segments can be interconnected through routers or switches to facilitate communication between them.
In a physical sense, a network segment refers to a physical portion of a network that is separated either by geographical distance or by the use of network devices such as switches or bridges. For example, a large organization may deploy multiple network segments within a building or across different buildings in a campus. Each segment may have its own set of devices, such as switches, routers, and servers, dedicated to serving the users and services within that segment.
Overall, network segments offer enhanced flexibility, scalability, and security by dividing a network into smaller units that can be independently managed and controlled.
Etymology of NETWORK SEGMENT
The term "network segment" is derived from two separate words: "network" and "segment".
The word "network" comes from the Old English word "neteweorc", which meant "net-like fabric or structure". It later evolved into "nettwerk" in Middle English, referring to interconnected threads or wires. The concept of a computer network emerged in the mid-20th century, referring to a system of interconnected computers or devices.
The term "segment" has its roots in the Latin word "segmentum", meaning "section" or "part". In the context of computer networks, a segment refers to a section or portion of the overall network. It typically represents a group of interconnected devices that share a common network address range.
When combined, the term "network segment" refers to a specific portion or section of a computer network, delineated by shared characteristics or addresses.
