Variable Length Subnet Mask (VLSM) is asubnet-- a segmented piece of a larger network -- design strategy where all subnet masks can have varying sizes. This process of "subnetting subnets" enablesnetwork engineersto use multiple masks for different subnets of a single class A, B or C networ...
A Variable Length Subnet Mask (VLSM) is a numerical masking sequence, or IP address subset, based on overall network requirements. A VLSM allows a network administrator to use long masks for networks with few hosts and short masks for networks with multiple hosts. A VLSM is used with a VLSM...
Using masks of variable length, the established objectives can achieve. For example, suppose your network is 192.214.11.0. First, use mask 255.255.255.128 to divide the network address into two subnets with 128 hosts each. These two subnets are represented by 192.214.11.0. (.0 to .127), the...
variable By TechTarget Contributor What is a variable? In programming, a variable is a value that can change, depending on conditions or on information passed to the program. Typically, a program consists ofinstructions that tell the computer what to do anddatathat the program uses when it is...
Here, x is a variable and can take any value. If x = 1, the value of this algebraic expression will be 2(1) + 6 i.e. 8 and if x = 2, the value of the algebraic expression changes to 10. Hence, we can say that the value of the algebraic expression varies as the x varies...

What is a Variable? The definition of a variable changes depending on the context. Typically, a letter represents them, and it stands in for a numerical value. In algebra, a variable represents an unknown value that you need to find. For mathematical functions and equations, you input their...
The main difference is that a zoom lens has a variable focal length while a prime lens has a fixed focal length. Here’s more on the differences: Zoom lens A zoom lens has a variable focal length (e.g., 16–35mm). This gives you a wide variety of focal lengths in one lens. Ther...
Variable overhead, as alluded to earlier, fluctuates according to levels of production. It may be tougher to pin down and keep within a budget. The key difference between variable and fixed overhead costs is that if production stopped for a period, there would be no variable overhead while...
A variable cost is an expense that changes in proportion to production output or sales. When production or sales increase, variable costs increase; when production or sales decrease, variable costs decrease. Variable costs stand in contrast to fixed costs, which do not change in proportion to pro...
