One physical network can be dividedinto multiple subnetworks or more commonly called subnets. The vector quantities, however, involve much more information than simply representable in a figure, often requiring a specific sense of direction within a specified coordinate system. Subnetting a network address in order to subnet a network address, the subnet mask has to be extended, using some of the bits from the host id portion of the address to create a subnetwork id. V vn v magnitude of v n unit vector whose magnitude is one and whose direction coincides with that of v unit vector can be formed by dividing any vector, such as the geometric position vector, by its length or magnitude. If we include two bits from the host part to the network part, the subnet mask is. All of these require a magnitude to be represented.
