Explain Network File System V 4 (NFSv4).

56.Explain Network File System V 4 (NFSv4).
Ans.
1. NFS version 4, offers better security and performance enhancement over previous versions of NFS protocols.

2. NFSv4 incorporates RPCSEC-GSS security, which makes it possible to encrypt the data stream transmitted between NFS client and server.

3. To increase performance, NFSv4 makes complete use of client-side caching to reduce the frequency with which clients must communicate with an NFS server. It increases overall performance by minimizing the number of server round tips.

4. NFSv4 extends its support to ACL (Access control list).

5. Although it is interoperable with NFSv3 but its clients cannot
mount NFSv2 Exports.

6. NFSv4 enhances performance over internet even on low bandwidth network connections.

7. NFSv4 also supports UTF-8 filenames making cross-platform and inter-character set file sharing more comfortable.

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 ...
