If you have yet to buy your first computer, you will want to have a specific purpose upon finally receiving or buying one. Having a purpose will drive motivation, fun, and gratification while also building other computer skills in the process. A nice choice for a computer newbie would actually be an Apple iPad, which is only $329 and relatively easy to navigate. From there, your understanding can translate to other computer operating systems like macOS or even Windows. Avoid old laptops though, as troubleshooting and sluggishness will frustrate you more than necessary.
Pulling out the power cord from an awake computer can put the machine at risk for hard drive failure. Interrupting a hard drive writing process could result in a mess of data all over the digital space. The ideal way to shut off a computer should always be the "Shut Down" option in the OS. If the computer is locked up, find a reset button or hold the power button for a few seconds before attempting to touch the power cord.
Richard is wondering if pulling the power cord on a computer (while it is on) hurts the machine. Leo says it is risky because if the computer/hard drive is in the middle of a writing process, pulling the plug could spew data all over the hard drive. Not to mention, physical damage could occur during the interruption as well. It is only okay to pull the cord when the computer is frozen solid and locked up. Unplugging is only a last resort, so always try to hold the power button first before attempting to cut off the power.
