Answer:
a: Twisted pair won't span a 400-foot distance.
Explanation:
The maximum distance that twisted pair cables can support without attenuation is 100 meters which is approximately 328 feet and the two office buildings are 400 feet apart, so it is useless to install a twisted pair cable for such a large distance. A much better option would be to install optic fiber. Though it is a bit expensive but it is the best option in this case.
Hence option (a) is the correct reason for installing an optic fiber cable rather than a twisted pair cable.
There are six basic functions of IT.
1. Capture: Compiling detailed records of activities.
2. Processing: Converting, analyzing, computing and synthesizing all forms of data and information.
3. Generation: Organizing information into a useful form.
4. Storage: Retaining information for further use.
5. Retrieval: Locating and copying stored data or information for further processing or for transmission to another user.
6. Transmission: Distributing information over a communication network.
Answer:
the type of reference
Explanation:
There are many cell reference types eg relative,absolute and mixed cell referencing. if you write your cell reference in relative type then it will change as you copy it to another cell. if you select absolute cell referencing then it will not change if you copy to another cell.
Answer:
Link-local address
Explanation:
IP addresses that have "FE80" as the hexadecimal representation of their first 10 bits are IPV6 reserved addresses for link-local unicast addressing. These addresses are automatically configured (though may be manually configured too) on any interface and should not be routed. They are used for addressing on a single link with the main aim, among others, of automatic configuration and routing protocol advertisement. Devices attached to this link can be accessed or reached using the link-local addresses as they don't need a global address to communicate.
However, routers will not forward datagram or packets using link-local addresses. In other words, routers are not allowed to connect to the internet using the unicast link-local addresses.
