Explanation:
Downloading an image from a website on the internet.
- Right-click the image.
- Choose the command Save Picture As. The command might be different in browsers other than Internet Explorer.

- Use wget -i images.txt.
- You will find all your downloaded files in the folder.
How your computer finds the CodeHS server, requests information from the server, and receives it.
- When you enter an URL into the address bar of browser, browser will send the domain to a server call DNS to convert the domain into IP address.
- For example: google dot com will be convert into 113.171.253.224
- Next, the browser will send your request to that IP.
- All your sent data will be divided into packages, each package contains your IP address.
- That is the reason why server know who it will send the response.
Solution:
Running computer programs and their data are stored in Rom.
ROM is "built-in" computer memory containing data that normally can only be read, not written to. ROM contains the programming that allows your computer to be "booted up" or regenerated each time you turn it on. Unlike a computer's random access memory (RAM), the data in ROM is not lost when the computer power is turned off. The ROM is sustained by a small long-life battery in your computer.
Answer:
A fixed expense is an expense that has a constant total expense value (the total amount of the fixed expense) that remains the same (does not change) when there is a change in the number being managed, manufactured, or sold
Examples of fixed expense includes; depreciation of assets, salaries of workers, payment for rental lease, and some utility payment, such as road users toll fees payment at a toll gate
Explanation:
Answer:
<h2> RAM</h2>
- <em>It</em><em> </em><em> </em><em>stands</em><em> </em><em>for</em><em> </em><em>Random</em><em> </em><em>Access</em><em> </em><em>memory</em><em>.</em>
- <em>It</em><em> </em><em>is</em><em> </em><em>used</em><em> </em><em>for</em><em> </em><em>both</em><em> </em><em>purpose</em><em>(</em><em> </em><em>read</em><em> </em><em>and</em><em> </em><em>write</em><em>)</em><em>.</em>
- <em>It</em><em> </em><em>is</em><em> </em><em>volati</em><em>le</em><em> </em><em>memory</em><em>.</em>
<h2>
<em>R</em><em>O</em><em>M</em></h2>
- <em>It</em><em> </em><em>stands</em><em> </em><em>for</em><em> </em><em>Read</em><em> </em><em>only</em><em> </em><em>memory</em><em>.</em>
- <em>It</em><em> </em><em>can</em><em> </em><em>be</em><em> </em><em>used</em><em> </em><em>only</em><em> </em><em>to</em><em> </em><em>perform </em><em>the</em><em> </em><em>read</em><em> </em><em>oper</em><em>ation</em><em>.</em>
- <em>It</em><em> </em><em>is</em><em> </em><em>non-volatile</em><em>.</em>

The script that Andy would want to use is Javascript, here is the source code: document.getElementById("para1").innerHTML = formatAMPM();
function formatAMPM() {var d = new Date(), minutes = d.getMinutes().toString().length == 1 ? '0'+d.getMinutes() : d.getMinutes(), hours = d.getHours().toString().length == 1 ? '0'+d.getHours() : d.getHours(), ampm = d.getHours() >= 12 ? 'pm' : 'am', months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'], days = ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'];return days[d.getDay()]+' '+months[d.getMonth()]+' '+d.getDate()+' '+d.getFullYear()+' '+hours+':'+minutes+ampm;<span>}
The HTML code needed to call this Javascript on his website is this: </span><span><div id="para1"></div>
</span>
You could call the Javascript up using PHP.
Hope this helps! Good luck! :)
