         <p>This part of a computer focuses on graphics. Graphics are images of all kinds (pictures, animations, videos). <u>The GPU delivers images, animations, and videos that can be viewed on the computers screen.</u> If you want to use the best picture quality for your favourite computer game, you'll need a high-end GPU to make the graphics look good.</p>
         <br>
         <p>Think of the CPU as a jack-of-all-trades (like a handyman) and the GPU as the master of a trade (like a plumber). The CPU is great for completing a variety of everyday tasks well; the GPU specializes in processing display information quickly. You wouldn't want a handyman to replace all the pipes in your home. Instead, you'd want your plumber to use his or her special skills to perform that task.</p>

+        <h2>Output</h2>
+        <p>Putput refers to the parts that the computer uses to send information to you. This includes the projector, the monitor, the printer, speakers, and headphones.</p>
+        <br>
+        <p>The parts of hardware all work together. Data (information) comes from the user (who may be the person or a computer) and goes through the imput device into processing. Data can then be placed in storage (saved) or taken out of storage and then sent to the user.</p>
+        <br>
+        <p>Is a touch screen an imput or output part? It's both.</p>
+        <br>
+        <p>The process is like digestion: We take in food, process it and store it, and then pass it out.</p>

+        <h1>A Closer Look At Software</h1>
+        <br>
+        <h2>Application Software (Apps)</h2>
+        <p>Application software (apps) are programs that allow the user to complete tasks.</p>
+        <br>
+        <p>"App" is short for "application."</p>
+        <br>
+        <p>Word processors, internet broswers, and games are all examples of application software. Every app in a phone's app store is also application software. There's a wide variety of application software, and programmers can specialize in one of the subcategories.</p>
+        <br>
+        <h3>For example:</h3>
+        <ul>
+            <li>A <b>Web Developer</b> is a programmer who makes application software that runs on websites.</li>
+            <li>A <b>Mobile Developer</b> is a programmer who writes application software for mobile devices like phones and tablets.</li>
+            <li>A <b>Game Developer</b> is a programmer who developes application software video games.</li>
+        </ul>
+        <br>
+        <h2>System Software</h2>
+        <p>System software are the programs that make sure the individual hardware devices work together and properly with other programs. <mark>Operating Systems</mark> like Windows on a laptop or iSO (the mobile operating system) on an iPhone are examples of system software (and also Android). Operating systems run in the background; you cannot see what they're doing on-screen. <u>The operating system makes it possible to install games, social media, and other apps on the phone.</u></p>
+        <br>
+        <p>Applications cannot work without the system software.</p>
+        <br>
+        <h3>Operating Systems</h3>
+        <p>Programs that communicate with hardware, allowing other programs to run in the background</p>
+        <br>
+        <p>Hardware and software are pretty much useless on their own. Only when they are put together in a complete system do they become tools.</p>
+        <br>
+        <p>For example:</p>
+        <br>
+        <p>Hardware + Software = Final Result</p>
+        <ul>
+            <li>Cameara + Photo App = Phone To Take Selfies</li>
+            <li>Keyboard And Printer + Word Processing Program = Printed Party Invitation</li>
+            <li>Car And Sensors And Camearas + Street Navigation Program = Self-Driving Car</li>
+        </ul>
