1 answer:

Answer:

(b) is used in Traceroute

(d) is used by Ping

Explanation:

ICMP is the short form of Internet Control Message Protocol. It is a protocol used by networking devices such as routers to perform network diagnostics and management. Since it is a messaging protocol, it is used for sending network error messages and operations information. A typical message could be;

i. Requested service is not available

ii. Host could not be reached

ICMP does not use ports. Rather it uses types and codes. Some of the most common types are <em>echo request</em> and <em>echo reply.</em>

<em />

Traceroute - which is a diagnostic tool - uses some messages available in ICMP (such as <em>Time Exceeded</em>) to trace a network route.

Ping - which is an administrative tool for identifying whether a host is reachable or not - also uses ICMP. The ping sends ICMP <em>echo request </em>packets to the host and then waits for an ICMP <em>echo reply</em> from the host.

ICMP is not required to solve NAT traversal problem neither does it have a new version in IPV6.

1. Name a two methods for creating text in Adobe Illustrator.
Fittoniya [83]

Answer:

Point type is a horizontal or vertical line of text that begins where you click and expands as you enter characters. Each line of text is independent—the line expands or shrinks as you edit it, but doesn’t wrap to the next line. Entering text this way is useful for adding a few words to your artwork.

Select the Type tool  or the Vertical Type tool .

The pointer changes to an I-beam within a dotted box. The small horizontal line near the bottom of the I-beam marks the position of the baseline, on which the text rests.

(Optional) Set text-formatting options in the Control panel, Character panel, or Paragraph panel.

Click where you want the line of text to begin.
