The connection between two devices is completed through cables. Cables are designed to allow data transfer from one device to the connected one through electrical signals. Cables come in different sizes and designs, depending on the intended use. When being designed and manufactured, every cable is tailored to a particular purpose. That is why you will find some cables that are bonded, twisted, or braided to form a cable assembly.
When shopping for a computer cable for data transfer, you should check its quality regarding losses that occur in it. A high-loss miscellaneous cable is likely to reduce the fidelity of data being transmitted through it. When that happens, you might lose the data or receive an altered version of it at the target device. Think of what will happen to your system if the data was a control signal meant for triggering a given process.
Low-loss miscellaneous cables ensure that the fidelity or integrity of the data is conserved. It is important to choose an appropriate cable for every application because some have an unacceptable rate of losses that will degrade your signal.
Does the quality of a miscellaneous cable matter? Yes. Quality of every cable in a computer system or any other application matters. You need to shop for quality cables that are shielded and have acceptable characteristics such as low impedance, capacitance, and low-loss. The selected cable should also meet the expectations regarding data rate and bandwidth. Your miscellaneous cables should not be the bottlenecks in your application.
