Basic Functions of Power and Data Cables
Power and data cables serve different but essential roles in electronic and communication systems.
Power cables are responsible for transmitting electrical energy from a power source (such as an outlet or battery) to a device. Their primary functions include:
Supplying Power: Delivering electricity to electronic devices, appliances, and machines.
Voltage Regulation: Ensuring the correct voltage and current reach the device safely.
Safety & Protection: Many power cables include insulation and shielding to prevent electrical hazards like short circuits or overloads.
Data cables are used to transmit digital or analog signals between devices for communication and information exchange. Their main functions include:
Data Transfer: Enabling communication between computers, storage devices, networks, and peripherals.
Signal Integrity: Ensuring data is transmitted accurately without loss or interference.
Connectivity: Facilitating wired communication in networks, audio/video systems, and industrial setups.
Common examples:
Power cables: AC power cords, USB charging cables, power adapters.
Data cables: Ethernet cables, HDMI cables, USB cables, fiber optic cables.
Both cables play crucial roles in powering and connecting modern electronic devices. 🚀

The two basic types of cables are power cables and data cables. Early PCs used a ribbon cable to connect both hard drives and floppy. Later the Hard drive cable was changed from 40 wires on 40 pin to 80 wires on 40 pins. The additional wires were grounds between each data carrier. Newer computers use a smaller serial ATA (SATA) cable that uses 7 individual wires - 4 data wires and 3 ground wires. Other data cables and connectors usually use a flat ribbon cable for connections in the case. Examples are the serial ports, parallel ports, USB ports. The early PC had few connections sold with it, and we used to use a multi-purpose card to add ports and memory capability. Since the card was overcrowded, an extra "back plane connector" was included to give you a place hook up your printer of modem. It connected with a ribbon cable and a "header" block that plugged onto pins on the multi card. The power connectors on the early PC power supply were round and a keyed header attached them to the motherboard. Newer Motherboards often have an auxiliary power connector that enhances the distribution of power to the motherboard. This is only a benefit if the computer power supply has isolated rails for the different voltage supplies, or if the board must use more current than the other wires can safely carry. Hard drives and floppy all used the same size 4 pin Molex connector. The mini power connector arrived with the smaller floppy. The new SATA drives use a special power connector. New video cards that are high performance usually include one or more power headers requiring a feed just for the video card, and possibly it's fan. Early fans for the computers piggy backed across the power connectors going to the disk drives. More modern designs have dedicated sockets on the motherboard to allow reading the fan speed or better yet, controlling the fan speed. Some mother boards allow the control of "case fans". The power and sensor wiring for these fans is a 3 conductor cable, and some use a fourth conductor as a control line.
To transport power & or data.
One of the basic functions of a computer are to input data and then process it. A computer also outputs data and stores data.

Doing that might give you interference with your data transfer rate.
This is a good example of a question you might get in a bad computer repair class.Never assume you know what a cable does.Always study the motherboard and see where every cable is connected. Then identify what the function of the cable is.That said. In a generic Personal Computer there are typically only two types of cables. Data and Power. Data connects the motherboard bus to your equipment (eg. HardDrive). Power cables feed power from the DC converter to your equipment.

Check that all cables, power and data cables are pluged in and working, verify that mains power is switched on to the monitor.
the four basic functions of the microcomputer are input, output, processing, and storage of data.
The first functions involved writing text to the screen, then adding integers, then other basic data functions were added.
The instructions of a program generally direct the computer to perform three basic functions over and over again. These functions are input, processing and output. Collectively, these functions operate the data processing cycle.
