Subnetting is the practice of dividing a network into two or more smaller networks. It increases routing efficiency, enhances the security of the network and reduces the size of the broadcast domain. 1. Fixed-Length Subnet Masking: Introduction:  A fixed-length subnet mask ( FLSM ) is a sequence of numbers of unchanging length that streamlines packet routing within the subnets of a proprietary network.  Addressing:   FLSM Static Routing:     2.Variable-Length Subnet Masking: Intoduction:  Variable-Length Subnet Masking (VLSM) amounts to "subnetting subnets ," which means that VLSM allows network engineers to divide an IP address space into a hierarchy of subnets of different sizes, making it possible to create subnets with very different host counts without wasting large numbers of addresses  Addressing:   VLSM Static Routing:    

Static Routing: Static routing is a form of routing that occurs when a router uses a manually-configured routing entry, rather than information from a dynamic routing traffic. Static Routing With 3 Routers:   This video explains the Static routing process in FLSM with 3 routers

Question Number may be different but you can see the Question and solution down there: S.No1.Question Ten students (s1,s2,s3,s4,s5,s6,s7,s8,s9,s10) are going to attend an event. There are lots of gift shops, they all are going to the gift shops and randomly picking the gifts. After picking the gifts they are randomly arriving in the billing counter. The accountant gives the preference to that student who has maximum number of gifts. Create a C program to define order of billed students? Downlaod: click 2. Consider a scenario of demand paged memory. Page table is held in registers. It takes 8 milliseconds to service a page fault if an empty page is available or the replaced page is not modified and 20 milliseconds if the replaced page is modified. Memory access time is 100 nanoseconds. Assume that the page to be replaced is modified 70 percent of the time. Generate a solution to find maximum acceptable page-fault rate for access time that is not more than 200 nan
