Explain network classes.

By
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 they must be configured.

 10. Routers has an internal program called a routing table, which it uses to send the data to a host or another router.

How to configure Network file system version 4 (NFSv4) client?

By
69.How to configure Network file system version 4 (NFSv4) client? Ans. 1. There are two new options listed in NFSv4 are introduced as: clientaddr and ports 2. The version 3 of NFS introduced NFS over TCP, which improved NFS’s reliability. 3. In NFSv3, users use the mount option i.e., tcp as client whether client wants to use TCP or UDP to communicate with the server. NFSv4 replaces tcp or udp with a single option i.e. ports=tcp or udp 4. The default buffer size for NFSv4 is 8192 bytes, but it can grow to as large and by 32,678 bytes, which results performance improvements. 5. Following are the mount options: clientaddr=n – Declares client to be multihomed proto=type – Declares port as either udp or tcp resize=n – declares read size of clients buffer wsize=n – Declares write size of clients buffer sec=mod – Declares security model as either krb, krb5 etc.

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.

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.
