The solution is contingent on your objectives. It can be useful if you need to transfer files from one computer to another (for example, on a USB key), but it is not required. USB is compatible with a wide range of devices, including printers, scanners, hard drives, and external hard drives. Because the USB ports are so little, the wires can be a pain.
One issue with USB is that there are so many various devices, power requirements, and ports (not to mention operating systems) to consider.
USB is better for peripherals and printers because everything plugs into one port and doesn’t require a separate power source. The correct driver must be installed on a computer linked to a USB printer, and the port must be configured in the computer to allow the printer to connect.
Because you have to put a full drive into a USB enclosure (even the smallest external hard drive has more storage than you’d want to put in a portable drive), it’s less helpful for data storage. You’ll need to purchase a USB hard disk enclosure and a power supply separately.
Some USB devices are better than others for transferring files between computers. A USB hard drive is ideal for moving data between computers because it can be used on multiple systems without needing to be configured. A USB CD-ROM is preferable since it can be configured as a CD-R, eliminating the need to set it to burn a CD. However, it may not allow you to duplicate it directly. Of course, it will still require power.
There are adapters for USB networking that allow you to connect a USB drive (such as a flash memory card) to a network adapter (such as a USB Ethernet adapter) to transfer files between computers. You can also use adapters to connect a portable printer to a network adapter.
It was created with the intention of being used with printers and scanners. They’re compact, and the connectors are simple to attach to the printer port on a computer. However, USB is now significantly more widely used. Digital cameras can be connected to computers via USB. It can be used to connect hard disks and other USB devices to a computer.
Another advantage of USB is that it may be daisy-chained, as you suggested. This means that any USB device can be linked to every USB port, enabling you to chain up to seven devices together.
USB cable doesn’t save any information. It’s necessary to connect to another computer or an external storage device in order to transfer data. This is much less expensive and time-consuming than plugging in a hard disk. However, keep in mind that USB is still a cable, therefore these are very long wires. A standard USB cable, for example, is about 5 feet long. It does not link the USB device to the computer; rather, it connects the computer to the USB device. This eliminates the need for a USB port on the motherboard. It does, however, require a free USB port on the computer to function.
