Port unreachable and TTL (Time to Live) Expired messages are received at the sending host.

In cases when a packet reaches an end-host destined for a UDP port for which no host is associated, it generates an ICMP port unreachable in response. Also, an ICMP Port unreachable message can be generated in instances where the router could not find the server.

TTL expired on the other hand is used upon the execution of traceroute command. An ICMP message is sent out with a TTL value of 1 set in the IP header. The end host receiving a traceroute probe would send a TTL Expired ICMP when a single probe finally reaches it.

____ twisted pair is the least quality twisted pair wire that should be used in a data/voice application.

xxMikexx [17]

Answer:

Category 5 (Cat 5) twisted pair is the least quality twisted pair wire that should be used.

Explanation:

The reason is as follows:

Category 1 twisted pair is not suitable for transmitting data but comes in handy for telephone communications. Hence, it should not be used in a data/voice application.
Category 2 twisted pair is suitable for data transmission, however, it can only transmit at 4Mbps which is very slow. Hence, it should not be used in a data/voice application.
Category 3 twisted pair can transmit data with speed reaching 10Mbps which is slow for voice/data communication.
Category 4 twisted pair can transmit data with speed reaching 16Mbps and is used in token ring networks. It is slow for communicating in a voice/data application.
Category 5 twisted pair is the least qualified to be used in a voice/data application because it can transmit data at speeds that reach 100Mbps.

Hence, Cat 5 or Category 5 twisted pair is the least quality twisted pair that should be used in a data/voice application.

Television broadcasts were originally delivered by using which technology

o-na [289]

Answer:

Wireless technology.

Explanation:

In earlier years, the broadcasting of information or any video or audio type was done "over-the-air". This means that sharing or the distribution of any content was done "wireless", through the use of transmitters that are wireless or requires no physical connecting wires.

Wireless technological form of broadcasting became the original form of distributing media, be it entertainment, news or information, etc. This 'over-the-air' broadcasting was then replaced by the cabled-wires transmission later on.

A customer wants to increase his storage capacity by 25gb

Tom [10]

The answer is "SSD-25GB", and its further calculation can be defined as follows:

The current generation of computer storage devices is a hard drive (SSD).
It uses a flash memory that is substantially faster than a conventional mechanical disc.
The user does not require Storage or GPU, Video Card cannot be used.
RAM is a memory volatile that cannot be utilized as storage media.
SSD is better than magnetic HDD in terms of speed and performance.
SSD has become substantially quicker than USB 3.0.

That's why the answer is "SSD-25GB".
