having the same subnet mask for all subnets ends up wasting address space. In this situation VLSM is used. During this method the subnets are of variable length‚ depending on the needs. For example for two serial link we can use subnet mask with /30 i.e. only two allowable hosts. If we need 6 hosts we can use a subnet mask of / 29 i.e. 6 allowable hosts. CIDR (Imp) Classless Interdomain Routing (CIDR) was introduced to improve both address space utilization and routing scalability in the Internet

INTRODUCTION: A local area network (LAN) is a network of computers that interconnects computers in a limited or a small area such as a home‚ computer lab‚ school‚ or office building using the network media. The defining characteristics of LANs‚ is in contrast to the wide area networks (WANs)‚ including their higher data-transfer rates‚ smaller geographic area‚ and lack of a need for leased telecommunication lines. ARCNET‚ Token Ring and other technology standards have been used in the past‚ but

exists. Without broadcasting the network people that are not aware of your network have no way of even knowing it is there. Another way to help to secure a WLAN is by using MAC address filtering. MAC filtering requires a list of the valid MAC addresses the user wants to be able to access the network. Any computer with a MAC address that is not on the provided list will not be able to gain access to the network. These steps alone are not enough to keep a network secure but when used with other security

through e-mail. E-mail spoofing involves sending messages from a bogus e-mail address or faking the e-mail address of another user. Fortunately‚ most e-mail servers have security features that prevent unauthorized users from sending messages. However‚ spammers often send spam messages from their own SMTP‚ which allows them to use fake e-mail addresses. Therefore‚ it is possible to receive e-mail from an address that is not the actual address of the person sending the message. Another way spoofing takes place
