What Do I Need to Know Before Buying My New Device for School?

We've got you.

This post is presented in partnership with Microsoft.

School’s in. For many, it means the time has come to spend big on a new device. But before you make such a massive investment, we're sure there are questions you need answering.

(It's okay to be confused. Admitting it is the first step.)

For instance, what exactly is an IntelCore processor? How much storage is 1TB really? What’s the difference between 227 and 264 PPI resolution? Is being ‘802.11a/b/g/n compatible’ even a good thing? And what in the world is a USB?! (Okay, you should already know that last one.)

Read on for answers to all the questions you were too afraid to ask!

What is a computer processor and why do computers need it?

This is kind of like asking, “What is a brain and why do I need it?” Without the processor—which “processes” basic instructions—your device is just a hunk of aesthetically-pleasing magnesium.

Intel’s processors are among the most used in the marketplace. As of this writing, Intel is up to its ‘7th Generation’ of processor. Obviously, the newer the better, but you only need the latest Gen if you want the absolute fastest performance possible. Consider what you’ll be using your computer for (like gaming, or simply writing) before deciding on an upgrade, as it’ll cost ya.

How much internal storage do I need?

Leading models offer you a few choices, usually beginning at 32GB. (Tablets and smartphones obviously start smaller.) If that doesn’t seem big enough for your needs, you can usually upgrade, perhaps all the way to 1TB (equalling 1000GB). However, those upgrades can be pricey, and your computer’s internal storage is really only for the essentials. An affordable external hard drive can be purchased on the cheap to help you store your music and other such hefty files. Better than paying for an absurdly—and unnecessarily—large internal memory. Still, don't skimp on internal storage if you plan on regularly using large programs and applications.

Oh, and don't confuse your internal storage with RAM (Random Access Memory, where data relating to in-use programs/applications live, for quick access). These can start as small as 2GB, but don't fret: You won't be using it for any kind of long-term storage.

What do I need to know about ‘Screen Resolution’?

1920 x 1080. 2736 x 1824. 3000 x 2000. You’ve likely seen these sums thrown around, and been left wondering what they actually mean. See, a computer screen is made up of pixels (which is the unit of measurement for elements within a picture). Resolution means the number of pixels on a screen. So, when you see something like “1920 x 1080”, that means the screen is 1920 pixels wide and 1080 pixels tall. Got it?

That said, pixels don’t indicate screen size or picture clarity. That's why you need to consider the PPI, which stands for pixels per inch. This number will explain how densely packed the pixels are on your screen; the denser, the more clearly the image will display. If you’re dead-set on a giant screen, inspect the PPI first. Hey, sometimes a smaller screen with a high resolution (and therefore, PPI) will look sharpest. If your priority is having enough space on your desktop for icons, screen size doesn't matter as much as a high resolution.

Battery life: Do I need it?

Uh, yeah; especially if you’re going to be moving from class to class and won't be able to charge throughout the day. You don’t need any special insight into technological minutiae to figure out what’ll suit you best. Shop around and find the largest number of hours!

Sure, my device is for school… but it'd be nice to play a game or two.

We hear you. Putting aside the need for an advanced processor (and generous RAM) to facilitate a fast-performing game, you’ll most certainly require a decent GPU (graphics processing unit) to get your game on. Literally every out-of-the-box computer will come with an integrated GPU of some sort; otherwise, you wouldn’t see anything at all on your screen. Some gamers invest in a separate graphics card, but if your device is running a recent Intel graphics chip (or something like it), you’ll probably be fine. If you have a particular game in mind—perhaps Overwatch or Minecraft—search for its name online alongside the specs listed against your preferred device, and you’ll probably find a list of recommended graphics cards. Then, you'll see if you're all set.

Okay, great, anything else?

Well, it wouldn’t be a bad idea to double check that your preferred computer has a headphone jack (given the trend to ditch these, in favour of slimmer devices). Also, depending on what you’re studying, you may want to see if the device you’re shopping for comes with any physical additions that’ll suit your subjects (such as a stylus, or in the case of Microsoft Surface devices, detachable flip screens).

And if you were still wondering, '802.11a/b/g/n compatible' means your device supports the most common wireless internet technology. Without getting bogged down in the details, if you see all those letters, that's a good thing. The only thing better is 802.11ac compatibility; this is the newest generation of Wi-Fi signalling. It's even backwards compatible, if that means anything to you.

Above all, know what it is you need from your device, do your research and take advantage of any discounts through Student Edge (obviously). You’ve got this.
