A logical address and numerical label that is assigned to a device that is connected to a computer network.

15

What is NAT?

Network address translation allows multiple computers on a network to connect to the internet through a single IP address.

18

Definition of Link local addresses

Private non-routable addresses confined to a single subnet. They are used by hosts when communicating with neighboring hosts on the same link.

19

What are unique local addresses?

Meant for private addressing, with the addition of being unique so that joining two subnets does not cause address collisions.

20

What is the role of Network and Sharing Center?

It provides real-time information about your network. Can be used to configure and manage network connections including wireless networks and the level of access.

21

What is the role of Network Discovery ?

It Allows this computer to see other network computers and devices and makes it visible to other network computers

22

What is the role of File and printer sharing?

It allows people on the network to access files and printers that you have shared on this computer.

23

What is the role of Public folder sharing?

It allows people on the network to access files in the public folder.

24

What is Media Streaming?

It lets people and devices on the network can acces pictures, music and videos on the computer.

25

What is password protected sharing?

Only people who have a user account and password on the computer can access shared files, printers attached to the computer and the public folders.

26

What are ports for?

A host uses ports to identify which packets belong to a network service or program.

27

What is the difference between ipconfig and ipconfig/all?

Ipconfig displays the IP address, subnet mask and default gateway for all adapters whereas ipconfig/all displays the full TCP/IP configuration for all adapters including host name, DNS servers and the Physical/MAC Address.

28

what does the command ipconfig/displaydns do?

This command displays the contents of the DNS client resolver cache which includes both entries pre-loaded from the local hosts file and any recently obtained resource records for name queries resolved by the computer.

29

What does the command ipconfig.registerdns do?

It initiates manual dynamic registration for the DNS names and IP addresses that are configured at a computer.

What is a DNS?

Short for Domain Name System, is a hierarchical client.server based distributed database management system that translates domain Host names to an IP address.

43

What is WINS?

short for Windows internet name service. Another name resolution technology which translates from netBIOS to a specify a network resource. Since the growth of the internet and the scalability of DNS, WINS is considered a legacy system.
