There is no ideal length of a cat 5 cable but the specification states that it should not be more than 100m (328 feet). The specification of 328 feet has to do entirely with collision detection in a CSMA/CD (Carrier Sense Multi Access / Collision Detection network.
Is RS232 straight through?

What is the difference between usb1 and USB2?
USB 2.0 is the successor standard was released in 2000 with the new transfer mode Hi-speed that can transfer data at up to 480 Mbit/s (40x times higher the rate of USB 1.0). USB 1.0 and USB 2.0 are: half duplex – can either send or receive data, power usage – up to 500 mA per one host controller.
How can you tell the difference between two USB ports?
You can generally tell the difference between USB 1.0, 2.0, and 3.0 by color alone. While the size and shape may be identical, the key is to look at the color of the plastic inside the device. The USB 1.0 features a white plastic color, while USB 2.0 is black, and the USB 3.0 is blue.
Can I connect a USB device to a 2-0 slot?
It’s possible to connect USB 3.0 and 3.1 devices to 2.0 slots, but keep in mind that the speed will only reach that of the USB 2.0, which is 480 Mb/s as opposed to the much faster 5 Gb/s and 10 Gb/s. Both the device and slot should be the same for the most optimal speed. USB 2.0 devices can also connect to USB 3.0 ports.
