Explain TCP/IP networking.

42.Explain TCP/IP networking.
Ans.
1. TCP/IP is transmission control protocol and belongs to the family of protocols used for computer communication.

2. TCP and IP are two different protocols from the group of protocols called as TCP/IP protocol suite.

3. TCP/IP protocols suite also includes address resolution protocol (ARP);Domain Name System (DNS);Internet Control message protocol(ICMP);User Datagram Protocol(UDP);Routing Information Protocol(RIP);Simple Mail Transfer Protocol(SMTP);Telnet and many others.

4. Each device connected to a network must have an address to communicate called as Device address.

5. Device address has two parts: the address of the network to which the device is connected and the address of device itself, i.e. host address.

6. These two unique addresses are called as network layer addresses and the media access control (MAC).

7. Network layer addresses are IP addresses that have been assigned to the device whereas Mac addresses are built into the Ethernet card by the manufacturer.

8. Data is transferred by breaking information into small piece of data called packets or Datagrams

9. Transferring data in packets avoids error in communication.

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

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.
