Why is USB Type-C so important?

Published

on

Over the past decade, devices using the Universal Serial Bus (USB) standard have become part of our daily lives. From transferring data to charging our devices, this standard has continued to evolve over time, with USB Type-C being the latest version. Here’s why you should care about it.

First, here’s a little history

Chances are you’ve encountered devices that have a USB port, such as a smartphone or computer. But what exactly is the USB standard? Simply put, it’s a communication protocol that allows devices to communicate with other devices using a standardized port or connector. It’s basically what language is for humans.

When USB was first introduced to the market, the connectors used were known as USB Type-A. You’re likely familiar with this connector; it’s rectangular and can only be plugged in a certain orientation. To be able to make a connection, a USB Type-A connector plugs into a USB Type-A port just like how an appliance gets connected to a wall outlet. This port usually resides on host devices such as computers and media players, while Type-A connectors are usually tied to peripherals such as keyboards or flash drives.

There are also USB Type-B connectors, and these usually go on the other end of a USB cable that plugs into devices like a smartphone. Due to the different sizes of external devices, there are a few different designs for Type-B connectors. Printers and scanners use the Standard-B port, older digital cameras and phones use the Mini-B port, and recent smartphones and tablets use the Micro-B port.

Specifications improved through the years

Aside from the type of connectors and ports, another integral part of the USB standard lies in its specifications. As with all specifications, these document the capabilities of the different USB versions.

The first-ever version of USB, USB 1.0, specified a transfer rate of up to 1.5Mbps (megabits per second), but this version never made it into consumer products. Instead, the first revision, USB 1.1, was released in 1998. It’s also the first version to be widely adopted and is capable of a max transfer rate of up to 12Mbps.

The next version, USB 2.0, was released in 2000. This version had a significantly higher transfer rate of up to 480Mbps. Both versions can also be used as power sources with a rating of 5V, 500mA or 5V, 100mA.

Next up was USB 3.0, which was introduced in 2008 and defines a transfer rate of up to 5Gbps (gigabits per second) — that’s a tenfold increase from the previous version. This feat was achieved by doubling the pin count or wires to make it easier to spot; these new connectors and ports are usually colored blue compared to the usual black/gray for USB 2.0 and below. USB 3.0 also improves upon its power delivery with a rating of 5V, 900mA.

In 2013, USB was updated to version 3.1. This version doubles what USB 3.0 was capable of in terms of bandwidth, as it’s capable of up to 10Gbps. The big change comes in its power delivery specification, now providing up to 20V, 5A, which is enough to power even notebooks. Apart from the higher power delivery, power direction is bidirectional this time around, meaning either the host or peripheral device can provide power, unlike before wherein only the host device can provide power.

Here’s a table of the different USB versions:

Version Bandwidth Power Delivery Connector Type
USB 1.0/1.1 1.5Mbps/12Mbps 5V, 500mA Type-A to Type-A,

Type-A to Type-B

USB 2.0 480Mbps 5V, 500mA Type-A to Type-A,

Type-A to Type-B

USB 3.0 5Gbps 5V, 900mA Type-A to Type-A,

Type-A to Type-B

USB 3.1 10Gbps 5V, up to 2A,

12V, up to 5A,

20V, up to 5A

Type-C to Type-C,

Type-A to Type-C

Now that we’ve established the background of how USB has evolved from its initial release, there are two things to keep in mind: One, each new version of USB usually just bumps its transfer rate and power delivery, and two, there haven’t been any huge changes regarding the ports and connectors aside from the doubling of pin count when USB 3.0 was introduced. So, what’s next for USB?

USB Type-C isn’t your average connector

After USB 3.1 was announced, the USB Implementers Forum (USB-IF) who handles USB standards, followed it up with a new connector, USB Type-C. The new design promised to fix the age-old issue of orientation when plugging a connector to a port. There’s no “wrong” way when plugging a Type-C connector since it’s reversible. Another issue it addresses is how older connectors hinder the creation of thinner devices, which isn’t the case for the Type-C connector’s slim profile.

From the looks of it, the Type-C connector could become the only connector you’ll ever need in a device. It has high bandwidth for transferring 4K content and other large files, as well as power delivery that can power even most 15-inch notebooks. It’s also backwards compatible with previous USB versions, although you might have to use a Type-A-to-Type-C cable, which are becoming more common anyway.

Another big thing about USB Type-C is that it can support different protocols in its alternate mode. As of last year, Type-C ports are capable of outputting video via DisplayPort or HDMI, but you’ll have to use the necessary adapter and cable to do so. Intel’s Thunderbolt 3 technology is also listed as an alternate mode partner for USB Type-C. If you aren’t familiar with Thunderbolt, it’s basically a high-speed input/output (I/O) protocol that supports the transfer of both data and video on a single cable. Newer laptops have this built in.

Rapid adoption of the Type-C port has already begun, as seen on notebooks such as Chromebooks, Windows convertibles, and the latest Apple MacBook Pro line. Smartphones using the Type-C connector are also increasing in number.

Summing things up, the introduction of USB Type-C is a huge step forward when it comes to I/O protocols, as it can support almost everything a consumer would want for their gadgets: high-bandwidth data transfer, video output, and charging.

Everyone’s angry at PlayStation’s new no-disc policy, and this is why

It’s a tragedy for nostalgia, ownership, and preservation.

Published

on

Check in with your gamer friends today. Today, a lot of gamers are up in arms over Sony’s decision to kill the physical game disc starting in 2028. But, if you’re a digital-only gamer or just not a gamer yourself, you might not understand the anger. If you want to understand the ire or just want to relate with your gamer friends, here’s a primer for you.

Ending the era of the physical media

Last year, Nintendo launched the Switch 2. Though the console still has a slot for physical cartridges, the Switch 2 also introduced the Virtual Game Card as a way to digitize your library of games.

Of course, the feature wasn’t positioned as a way to eliminate physical cartridges. In fact, Nintendo just wanted to add the flexibility of physical cartridges to the digital world. In the end, the feature strangely coincided with less cartridges. For example, Pokémon Pokopia, one of the most popular games this year, does not come with a cartridge even if you buy a “physical” copy in a brick-and-mortar store. It was a portent of things to come.

Fast forward to today, Sony has made the monumental decision to stop producing physical game discs starting in 2028. The PlayStation’s future is completely digital.

On a similar note, Microsoft is also experimenting with a disc-to-digital feature. Much like the Nintendo Virtual Game Card, the experiment will digitize libraries and attaches the digital copy to the physical game disc. It sounds awfully like a prelude to killing off the game disc.

Why this matters

The physical disc is synonymous with a simpler time. It represents a time when gamers camped out stores to anticipate midnight releases, when gamers can learn more about their games through an in-box manual, and when gamers can show off their fandom through a beautifully stocked shelf of games.

And yes, that’s part of why this situation sucks, but it’s not the only reason.

If you’re an outsider looking in, this nostalgia factor is the easiest to see. Then again, it’s also the most difficult to relate with, especially if you’ve never had the history of buying physical games.

The more crucial reason — and the one that most people will relate with — is media ownership. By not having a physical copy, you will no longer have ownership of what you bought digitally.

And it’s not an imaginary issue. In 2024, Steam amended its policies to reflect that players do not own the games they buy. Rather, they simply own a license to play the game.

In the same year, Ubisoft delisted The Crew, a sure sign that the new policy means business. Though Steam itself has a relatively good track record of prioritizing its customers, publishers and developers can get rid of games if they choose to.

That limitation doesn’t exist with a physical copy. As long as you have a working disc drive, you can install a game whenever you want, even if the publisher decides to pull it from stores.

Therein lies how much this is a touchy topic. Should you own digital goods in the same way as you own physical ones? If the answer is yes, then selling only the license for the good doesn’t make sense. But if it’s a no, we shouldn’t pay full price for something we don’t own anyway.

Will PlayStation actually delete games?

Now, just because they can, does it mean that they will?

Right now, it’s hard to say. You can certainly go by the optimistic hope that PlayStation would never do something as anti-consumer as that. And yes, there are times when you’d be right.

Plus, there is a good chance that governments, especially those in the European Union, will protect consumers if PlayStation even thinks about deleting a game that others have paid for. Governments have been known to intervene in the past, such as when the EU forced Apple to adopt USB-C as a standard. There are checks and balances available.

Then again, Sony has had recent history of deleting media from a user’s library.

Only a few days ago, PlayStation made headlines for deleting over 500 titles from their library. Starting September 1, users can no longer access movies distributed by Studio Canal, due to licensing agreements. Sony was unapologetic about unceremoniously deleting this content. No refunds, no apologies; just 500 movies, which you thought you bought, gone for good.

No matter how you angle it, Sony’s recent decisions just don’t bode well for media ownership.

You can argue that this is the price we’re paying for not buying enough physical games. Still, losing PlayStation discs, even as an option, is tragic for nostalgia, ownership, and preservation.

The world we live in

Unfortunately, this all comes with precedent. Unless you buy physical games and movies, we already don’t own anything in today’s world.

Outside games, Netflix and Disney+ remove the ownership of movies and shows from us. It’s already common practice for these platforms to remove titles regularly. Some platforms even give you a last chance to catch these titles before they go away. Moreover, they can even restrict access, like with Disney+, if you travel abroad.

In exchange for convenience, subscription services and digital storefronts have made it all too comfortable to not own media. With a rental service like Netflix, that’s all expected, but we’re now at the inevitable stage when even bought games and movies are at the behest of our corporate overlords.

This is where the fury comes from. Companies are getting more brazen about taking more options from us. Between this and the increasing prices of RAM, it’s getting harder and harder to live as a tech-savvy citizen in today’s age.
