Document Summary

When a network is segmented into multiple smaller networks, traffic on one network is separated fro(cid:373) a(cid:374)other (cid:374)et(cid:449)ork"s traffi(cid:272) a(cid:374)d ea(cid:272)h (cid:374)et(cid:449)ork is its o(cid:449)(cid:374) (cid:271)road(cid:272)ast do(cid:373)ai(cid:374). A network administrator might separate traffic to accomplish the following: 1) enhance security: Broad(cid:272)ast do(cid:373)ai(cid:374)s are li(cid:373)ited to ea(cid:272)h (cid:374)et(cid:449)ork so there"s less possi(cid:271)ility of ha(cid:272)kers 2) improve performance: segmenting limits broadcast traffic by decreasing the size of each broadcast domain. 3) simplify troubleshooting - easy to examine, for example, it"s easy to examine smaller network rather than larger networks, thanks to segmentation. Ipv4 address has 32 bits and is divided into two parts: the network portion, which identifies the network, and the host portion, which identifies the host. host. How does a computer know how many bits of its ip address is the network. Bits: first to find the network id, you need to identify what class it is. subnet mask.
