Answer:
To get the IP address and other information on the workstation, type 'ipconfig' for windows or 'ifconfig' or Linux and press the return key.
The subnet mask is a class B type and 169.254.14.11 IP address shows that the workstation cannot access the DHCP server, so the IP address is not properly configured for network connection.
Explanation:
A computer network is an interconnection and intercommunication of two or more computer devices. All devices in a network must have an IP address, which can be static or dynamic from a DHCP server.
When a computer is configured to receive IP address from a DHCP server, but cannot reach the server, the IP address from the range of 169 is automatically assigned to it but still would not be able to communicate with other devices in the network.

The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches of rain falls yearly. Rain forests belong to the tropical wet climate group.
Explanation:
- The temperature in a rain forest rarely gets higher than 93 °F or drops below 68 °F. The average humidity is between 77 and 88%, rainfall is often more than 100 inches a year. In monsoonal areas, there is a real dry season.
- Rainforests now cover less than 6% of Earth's land surface. Tropical rainforests produce 40% of Earth's oxygen.
- About 1/4 of all the medicines we use come from rainforest plants. Curare comes from a tropical vine, is used as an anesthetic and to relax muscles during surgery. Quinineis used to treat malaria.
- There are four very distinct layers of trees in a tropical rain forest. They are the emergent, upper canopy, understory, and forest floor.
- The soil of the tropical rainforests is shallow, poor in nutrients and without soluble minerals. Years of rainfall have washed away the nutrients in the soil obtained from weathered rocks.
- The tropical rain forest can be found in three major geographical areas around the world.
-
Central America in the the Amazon river basin. Africa - Zaire basin, with a small area in West Africa. Indo-Malaysia - west coast of India, Assam, Southeast Asia, New Guinea and Queensland, Australia.
