Buyer's Guide
USB ports have become ubiquitous in modern life. They allow us to connect our computers, phones, tablets, cameras, and other electronic devices to each other and to power sources. However, not every USB port is created equal - some are better than others. This article explains what makes a good USB port, and why you might want to avoid certain ones.
The USB ports on most computers connect to external peripherals like printers, scanners, cameras, and more. Most modern computers come with at least two USB ports, but some even have four! This allows for multiple connections to be made simultaneously, allowing you to plug in several different types of devices all at once without having to unplug any of them first.
If you need to connect many different kinds of devices at once, a computer with four USB ports will allow you to make this happen. You could connect a printer, scanner, camera, mouse, keyboard, speakers, and more all at once. If you only need to connect one device at a time, there are still benefits to owning a computer with four USB ports. For example, if you only need to print documents occasionally, you may find yourself needing to disconnect the printer while using a different kind of peripheral. With a computer with four USB ports, you won't have to worry about accidentally unplugging something important.
The USB ports on most computers only offer two connections. But that doesn't mean you can't connect four devices at once. With a hub, you can add another connection to any device that has one. This makes it possible to charge multiple devices at once.
USB hubs are useful for charging cell phones, tablets, cameras, MP3 players, and other portable electronics. They also let you use peripherals such as printers, scanners, and speakers while keeping your laptop free for typing documents or surfing the web.
Hubs aren't limited to laptops either. Many desktop PCs now feature built-in USB ports. These allow you to plug in external hard drives, thumb drives, and other devices. Some models even support wireless networking.
There are several types of hubs available. Most are designed to fit standard USB 2.0 connectors. However, some newer models accept 3.0 connectors. Even better, some hubs are equipped with power supplies. This lets you recharge batteries using the same connector.
If you already have a USB hub, you can easily upgrade to a model with more ports. You can then plug in additional devices.
Some manufacturers sell USB hubs separately. Others bundle them with other products. Still others sell them online. Regardless of where you shop, you'll probably find a variety of prices and features.
• More ports - As mentioned above, some models support three or four connections. Look for this number on the product page.
• Power supply - Some hubs include a built-in battery charger. This allows you to use the same unit to charge mobile devices or recharge batteries.
• Wireless connectivity - While wired networks are still the best solution for connecting devices, wireless technology offers convenience and flexibility. Some hubs support Wi-Fi, Bluetooth, and/or infrared signals.
• Multiple speed settings - Most USB hubs operate at a maximum of 480Mbps. However, some models support faster speeds of 1.5Mbps and 5Mbps.
USB ports. USB ports are convenient, but they can be expensive. That's why it's important to know how many USB ports you actually need. The standard number of USB ports available on most computers is four. However, if you plan on using more than four USB devices at once, you may want to invest in a hub.
Hubs. Hubs allow you to connect multiple USB devices together into one connection. This makes it easier to charge your cell phone while charging other items such as MP3 players and digital cameras. Most hubs feature two USB connections, although some models feature three or even four USB connectors.
Compatibility. Many laptops and desktop PCs now feature built-in USB ports. These ports are usually located near the front edge of the device. Some manufacturers place these ports on the side of the laptop or PC instead. In either case, you'll want to check to make sure the port you're purchasing supports your specific model of laptop or PC.
Size. While there are several types of USB ports available, the most common type is the micro-USB connector. Micro-USB connectors are smaller than traditional USB plugs and can fit inside a variety of electronic devices including mobile phones, mp3 players, digital cameras, and portable speakers.
Power. When you're shopping for a USB port, you'll want to make sure it has enough power to handle whatever devices you plug into it. Make sure the port features a 5V/2A output rating. This means it can supply 2 amps of current for each port.
Cost. Buying a USB port isn't always inexpensive. But, you can often find deals on USB ports online.
The USB ports on computers are essential for connecting peripherals such as printers, scanners, cameras, speakers, and keyboards. Unfortunately, they don’t always stay connected to the device they were originally attached to. That’s why it’s important to know how to remove a USB cable from its original port. Here are four ways to do it.
Remove the plug. When removing a USB cable, simply pull off the plug. This is the easiest way to disconnect a USB cable. Just remember to keep track of the plug so you don’t accidentally throw it away.
Unplug the power cord. Unplugging the power cord is the second easiest way to disconnect a USB cable. Simply unplug the power cord and wait until the light turns off. Then gently tug on the end of the power cord to detach it from the wall outlet.
Pull the plug. Pulling the plug is the third easiest way to disconnect a USB cable. To do this, grab the plug and yank it straight up. This should release the connection between the plug and the socket.
Use a paper clip. A paper clip is the fourth and last way to disconnect a USB cable. Insert the tip of the paper clip through the hole in the plug and twist it clockwise. This should loosen the connection between the plug and the socket.
