According to the structure of the polymer, it is classified into- Linear polymers Branched-chain polymers Cross-linked or network polymers Co-polymers

According to the structure of the polymer, it is classified into- Linear polymers Branched-chain polymers Cross-linked or network polymers Co-polymers Correct Answer All I, II, III

The correct answer is Option(3) .i.e.All I, II, III.    

  • According to the structure of the polymer, it is classified into three types. 
  • Linear polymers: 
    • The linear polymer consists of a straight & long-chain structure.
    • Examples- Polyvinyl chloride(PVC), High-density polythene, etc. 
  • Branched-chain polymers:
    • Polymers having some branches in a linear structure.
    • Examples -Polythene of Low-density.
  • Cross-linked or network polymers:
    •  To form a 3-dimensional network polymer, the monomer units are cross-linked together in this structure.
    • Examples-melamine, Bakelite, etc. 
  • ​Polymers:
    • Polymers are substances of high molecular mass, which consisting of a huge number of structural units.
    • The polymers are generally single entity & some of them are big size molecules means giant molecules, are also called macromolecules. 
    • A polymer is a macromolecule that is a combination of many subunits.  
    • It naturally occurring biopolymer to polypropylene, used as plastic throughout the world.

You are the administrator of a Windows 2000 Server computer. The server contains one network adapter and is a file and print server for critical company resources. You install a second network adpater in the server and connect it to the same network subnet as the first adapter. You want to ensure that the first adapter is used for all network traffic and the second adapter is used only if the first adapter fails or is disconnected from the network. You also want to ensure that the server always has network connectivity even if one network adapter fails. What should you do?

Your network uses TCP/IP as the only network protocol. Devices on the network are configured to use IP address from the private 10.0.0.0 range. All the client computers on the network runs Windows 2000 Professional. The network includes Windows 2000 Server computers and UNIX servers. User's print jobs are sent to shared printers on a Windows 2000 Server computer named PrintServ that directs the print jobs to print devices attached directly to the network. You have a high-capacity print device that is attached to one of the UNIX servers. The UNIX computer uses the LPR printing protocol, and it's IP address is 10.1.1.99. The name of the printer queue is GIANT. You want users to be able to connect to this printer from their computers. What should you do?
