Of all the different ports that are built into computers today, none is more prominent than the USB port. Every computer, from the most budget-friendly laptop to a high-end liquid-cooled desktop, has at least one USB port somewhere on it. The trouble is when you have a computer with USB ports and not much else. Luckily, USB adapters can be used when you need to change USB into another format.

Cables to Keep Around the House
Spring is here and a lot of us are going to use that nicer weather to get a little cleaning done. If your house is anything like everyone else's, there is probably a junk drawer somewhere with a big mess of old cables. After untangling all the knots, you will want to look at each cable to see what you should keep and what can be tossed.

“Pinout” is a term describing how an electrical cable is wired. Some cables do not have pinouts because they only contain a single internal wire, like coax cables. But if a cable has multiple pins on the end of the cable, it will have a pinout.
Each type of multi-pin cable has a standard pinout or two, but these layouts are not set in stone. Some machines will require non-standard pinouts; this will require users to use a custom cable.
Pinouts also come into play when using a cable with two different ends. For example, going from DB9 (9 pins) to DB25 (25 pins) will mean the DB25 side has 16 unused, “dead” pins.
If you need to know what pinout a cable needs, ideally there will be a spec sheet h
Cable splitters are used to connect multiple TVs, computer monitors, or other devices to a single signal source. There are differences between the various types of splitters, but a few general rules apply to them all. Splitters only go from one input to multiple outputs; if you need to go from multiple inputs to one output, you need a switch instead.
When a signal goes through a splitter, it is divided and becomes weaker. Imagine an HDMI splitter as an example. Modern HDMI cables are capable of a 4k signal, which works fine if you are using a single HDMI cable by itself. However, say you use a 4-way HDMI splitter to run four cables to four TVs. Each signal would only have half the normal strength so none of the TVs will have 4k quality.
Because the signal is evenly divided, the signal will become weaker for bigger splitters.
3.5mm jacks, also called headphone jacks, are the most common type of audio cable. There are different variations of this jack, such as the smaller 2.5mm and the larger ¼”, but they are all functionally similar. 3.5mm cables are commonly available as off-the-shelf items, but sometimes a repair it easier than a replacement. Other times, users need a custom size not available as a standard cable.
This guide will show users how to assemble 3.5mm themselves, either as a repair or brand-new in
Audio and video cables go hand-in-hand, often being paired together. Some cables can even transmit audio and video on just one line. Over time a lot of new audio and video cables have been introduced, so the cable you need will often depend on the age of the equipment you are using. Most TVs, computers, and other devices can use multiple types of audio and video connections, so it is good to be able to identify them and know your options.
