1. USB Cable
USB cables are the most widely used connections in computers. They connect keyboards, mice, printers, cameras, and flash drives. USB supports data transfer and power delivery.
USB versions include USB 2.0, USB 3.0, USB 3.1, and USB4. Newer versions offer faster speeds and better power output. USB Type-A, Type-B, Micro USB, and Type-C are common connector shapes.
2. HDMI Cable
HDMI cables transmit high-quality video and audio through a single connection. They are used for monitors, TVs, and projectors. HDMI supports HD, Full HD, 4K, and even 8K resolution.
This cable is popular because it reduces clutter. One cable handles both sound and display. It is a standard choice in modern computer setups.
3. VGA Cable
VGA is an older video cable used mainly with legacy monitors and projectors. It carries analog signals only. Image quality is lower compared to digital cables.
Despite being outdated, VGA is still found in schools and offices with older equipment. It is slowly being replaced by modern alternatives. Know more about VGA Connector: Basics, Pinout and Important Types
4. DVI Cable
DVI cables were introduced to improve video quality over VGA. They support digital signals and offer sharper images. DVI comes in DVI-D, DVI-I, and DVI-A types.
Many desktop monitors still support DVI. It is reliable for basic display needs but does not carry audio.

5. DisplayPort Cable
DisplayPort is a high-performance digital display cable. It supports high resolutions, high refresh rates, and multi-monitor setups.
This cable is common in professional workstations and gaming systems. DisplayPort is often preferred over HDMI for advanced displays.
6. Ethernet Cable
Ethernet cables connect computers to networks and the internet. They provide stable and fast data transfer compared to wireless connections.
Common types include Cat5e, Cat6, and Cat6a. Higher categories support faster speeds and lower interference. Ethernet is essential in offices and data centers.

7. Power Cable
Power cables supply electricity to computers and monitors. Desktop computers use separate power cords for the CPU and display.
Using the correct power cable prevents overheating and electrical damage. Always match the cable rating with the device requirements.
8. SATA Cable
SATA cables connect internal storage devices like hard drives and SSDs to the motherboard. They support fast data transfer inside the computer.
Modern systems use SATA III for better speed. These cables are thin and easy to manage inside the case.

9. IDE Cable
IDE cables were used in older computers to connect hard drives and optical drives. They are wide ribbon cables with multiple connectors.
IDE is now obsolete. It has been replaced by SATA due to better performance and easier installation.
10. Thunderbolt Cable
Thunderbolt cables offer very high data transfer speeds. They can carry data, video, audio, and power through one connection.
Thunderbolt is common in high-end laptops and professional devices. It is ideal for external displays and fast storage solutions.
11. Audio Cable
Audio cables connect speakers, headphones, and microphones to the computer. The most common type is the 3.5mm jack.
Some systems also use optical audio cables for better sound quality. Audio cables play a key role in multimedia setups.
