Explain the concept of subnetting the network.

48.Explain the concept of subnetting the network.
Ans.
1. Every IP network has two addresses that cannot be used –The network IP number itself and the broadcast addresses.

2. Every time we subnet we are creating these two unusable addresses, so the more subnet we have, the more IP addresses we lose.

3. We need to determine the subnetwork mask and network numbers. Subnetworking takes one or more of the available host bits and makes them appear as network bits to the local interfaces.

4. If we want to divide our Class C network into two subnetworks, we’d change the first host bits to ones, and this would give us a net mask of 255.255.255.192

5. Lastly, assign the appropriate numbers for the network, the broadcast address, and the IP addresses for each of the interfaces.

Absolute Links vs. Relative Links – SEO Value

Absolute Links vs. Relative Links – SEO Value The debate between  absolute links and relative links  continues to live on in the SEO world. The individual significance of each has been contested, but it is widely regarded that absolute links provide better SEO value on the whole than relative links. Many believe that absolute links have less potential for getting messed up when search engines index your page. It shouldn’t really make a difference, but many conclude that this is reason enough.

Explain network classes.

43.Explain network classes. Ans. 1. TCP/IP network are 4 bytes long, called IP addresses and written in dotted-decimal notation. (ex. 192.168.166.5) 2. The decimal numbers must be within the numeric range of 0-255, each IPv4 addresses consist of 4 parts. 3. Each part should conform to the 1-byte requirement. 4. Depending on the value of the first byte of the address, IP addresses can be divided into classes. 5. Network classes are of 3 type and have some specific range • Class A 0-127 • Class B 128-191 • Class C 192-233 6. Class division enables us efficient use of the address numbers. 7. Assigned network numbers are maintained in a database managed by InterNIC to insure that each assignment is unique. 8. After obtaining a network number, the host numbers may be assigned as required, for data transfer ARP maps the IP address to the MAC address of the device. 9. Routers are used for transferring data between 2 devices, routers are default gateway ...
