Problem: Article: If you don’t want to expand externally, but don’t have any extra space inside the computer, you can replace the CD, DVD, or Floppy (AKA Optical Drive). A standard 3.5” internal desktop hard drive is a good way to add lots of space for cheap. Both hard drives and optical drives can utilize either an IDE or SATA interface cable(two alternates to USB). Most hard drives will come bundled with the cables they need, but you may need to purchase them separately as well. Most optical drives utilize a 5.25” expansion bay, which is too large for a 3.5” hard drive. You may need mounting brackets or a 5.25” to 3.5” bay adapter. Consult your manufacturer’s specifications to verify the size of your optical drive first. The expansion bay is the space that holds the drive. Both mounting brackets and bay adapters will allow you to fit your smaller hard drive into the larger space. You want to make sure the computer is completely powered off and unplugged before touching any of the electronic components. You will likely need a screwdriver to open the computer wall. The type of screwdriver will vary depending on manufacturer. Most optical drives are connected via two cables: power and data.  The power cable typically has a white tip attached with black, yellow, and red wires. The data cable has a wide tip attached to a ribbon cable. Once the screws are removed, the drive should either slide out or release with a latch. Secure the necessary adapter with screws. Slide the drive into the bay and reattach the screws. Reattach the power and data cables. You will need to plug the computer back in to setup the drive. BIOS (Basic Input/Output System) is the software used by the processor to identify its hardware like your newly installed hard drive. Different manufacturers use different software to access and modify the BIOS. Consult the manufacturer’s specifications to confirm exactly how to access the BIOS and the hardware section within.  Power on the computer, and press the necessary key during the startup screen. Look for a tab named “Hardware”, “Setup” or something similar. Navigate using the keyboard. You should see your newly installed hard drive listed. If not, power off the computer and double check the cable connections. Look for an option labeled “Auto-detect” and make sure it is enabled. Save and Exit. This usually has a specific key bound to it in BIOS. Your computer should restart automatically. The drive needs to formatted into a filesystem that your computer can read before it can be used. If you plan to use any Windows system files you will need to format to NTFS, but for simply storing data a filesystem like xFAT or FAT32 will be fie. The following steps are for Windows 10, but should work for other versions of Windows as well.  Press Windows Key + R to bring up the run menu. Type diskmgmt.msc and press OK. This launches the disk management tool. Right-click the new hard drive in the list and select ‘Format…’ Select your desired filesystem and press OK. Formatting a disk can take some time depending on the storage size of the disk. Once formatting is complete you can use your new hard drive to store data!
Summary: Purchase a new internal hard drive. Acquire necessary adapters. Remove power from the computer. Open the computer. Disconnect the cables attaching the drive. Unscrew and remove the drive. Install the mounting brackets or bay adapter (if necessary). Mount the hard drive in the empty bay. Connect the hard drive to the motherboard. Restore power to the computer. Setup the drive in the BIOS. Format the Drive.

In one sentence, describe what the following article is about: Almost all app-creation programs will require you to create an account and log in before you can get to work. You may need to download software, or apps may be created entirely through the website. After logging into the creation tools or downloading the creation software, you will need to start a new project. The process varies from program to program, but generally involves naming your app a name and description. Most app development programs will ask you to set a basic theme and color palette before you begin building the app. You will be able to change these choices later once the app is under construction. You may be able to add your own images for screen backgrounds. These images should typically be 1024 X 768 px. Most app creation programs work by letting you add prebuilt functions into your app. The combination of these functions and how they link together is what will make your app yours. There are a variety of different functions you can add to your app, including calendars, photo galleries, podcasts, Facebook integration, audio players, and more.  Typically, each one of these functions will be its own screen on your app. As you add functions, you will be able to customize each screen with your own text and content. For example, if you add an RSS feed function, you can link to your blog's feed and automatically populate the app with your latest posts. After you've added a few functions to your app, spend some time organizing the layout of each screen so that you have a cohesive look for your app. Your title bars should all be in the same location, and content should appear in consistent parts of the screen. Different app creation programs will give you different levels of control over how everything is laid out. Some apps only let you add completely prebuilt functions, while others allow you to drag and rearrange each element on the screen. You will have the opportunity to assign icons to each of your app's functions. Many app creation programs have a library of icons you can choose from, or you can design and upload your own. Good icons will help set your app apart and contribute to the overall feel of the app.
Summary:
Log in to the program you choose. Start a new project. Choose a theme. Add functions, or activities, to your app. Adjust the layout of each of your screens. Choose icons for your functions.
