Answer:
(a)Applications Time Stamp Events
(b)S=0.5(W-)+, where ≤W≤+8.
Explanation:
Some applications assume that clocks always advance, so they could timestamp events under this assumption.
In our case we have the wrong timed clock, say W and the hardware clock H which is supposed to advance at a perfect rate.
We proceed to construct a software clock such that after 8 seconds we can replace the wrong timed clock with the software clock in good conditions.
Let us denote the software clock with S.
Then, S=c(W-)+ where:
=The current Time(10:27:54) and;
c is to be found.
We already know that S=+4 when W= +8,
So:
S=c(W-)+
+4=c(+8-)+
4=8c
c=0.5
We obtain the formula
S=0.5(W-)+, where ≤W≤+8.

Answer:
(c) Router Delay
Explanation:
The network layer of the TCP/IP provides a mechanism or tool for troubleshooting and error messaging called Internet Control Message Protocol (ICMP). Network layer devices such as routers may use this tool to communicate errors especially if there is an issue delivering data packets.
Some of these error messages are;
i. Source Route Failed
ii. Source Host Isolated
iii. Network Unreachable
iv. Host Unreachable
v. Destination Network Unknown
vi. Destination Host unknown
Note:
Router delay is not one of the error messages identified by the ICMP.
Answer:
HypeTextMarkupLanguage aka HTML is a Markup Language (as in the name) and is used for making websites and functions that you would add variables using Javascript. CSS aka Cascading Style Sheets, is a style sheet. The purpose of CSS is to make the site/game or whatever your making too look nice.

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Example</title>

<style>
body {
background-color: yellow;
}
</style>
</head>
<body>
<!-- In HTML you can make buttons or links -->
