There are varied peripheral devices you may wish to connect to your primary system. You may be a gamer and need to connect a gaming controller or a joystick to your PC; you may be a digital artist and need to connect your tablet to your computer; if you want to use a projector, you need a suitable cable to connect it to your computer. And knowing which cable to use for optimal results solves half your problem.
Let me give you a quick rundown of some of the different types of computer cables:
HDMI stands for " High Definition Media Interface." This type of computer cable is used to carry high-definition audio and video signals. When you use an HDMI cable to transfer video and audio signals, be assured that they will be done without losing out on the quality of the images; they will be received crystal clear. Using an HDMI cable, you are able to connect lots of things, such as TVs, DVD players, and other devices. All sorts of audio/visual devices can be connected via an HDMI cable. Moreover, a single HDMI cable is able to carry both video and audio signals simultaneously.
As mentioned earlier, a standard computer setup includes a monitor connected via a cable. Ideally, you would use a VGA (video graphic array), which transmits analog signals and supports up to 640 x 480. Taking it one step further, we have the SGVA (super video graphic array) cable, which carries analog signals and supports resolutions up to 800 x 600. Another name for SVGA is ultra/enhanced VGA. Most SVGA monitor cables on the market do support a higher display resolution than the 800 x 600 standard. Read more about the Types and Uses of VGA Cables.
You use a DisplayPort cable when you want to connect a computer to a display device. These cables are specifically designed to carry audio and video signals over one cable. Displayport cables come with a distinctive connector that has 20 or more pins and are available in various lengths to work with different distances between the display device and the source device. These cables are mostly used in computer systems and are able to support resolutions up to 8K, HDR content, and high refresh rates.
An Ethernet cable is a computer network cable that is used to establish a wired network. An ethernet cable is used to connect monitors, switches, and personal computers to the Local Area Network (LAN). The durability and length of the cable determine the quality of the connection. Should the cable be too long and not durable, then the signal quality will be poor. An ethernet cable may look like a cable, but it contains more wires than found in cables. If you're interested in computer networking, you might have heard the terms Ethernet cable, LAN cable, and network cable used interchangeably. However, are they really the same thing? Let's explore the similarities and differences between Ethernet cables, LAN cables, and Network cables and clarify any confusion.
The basic cable that is used to connect the keyboard and mouse to a computer system is the PS/2 cable. Its length is long enough for the user to easily connect the keyboard and mouse to the device. Your typical PS/2 cable has a round connector and a total of 6 pins. It comes in two sizes: the smaller one is, the more common of the two, but there are some connectors that are used to convert these to a larger size.
3.5mm audio cables are cables that are used to connect audio applications to computers. This cable is used to connect a mini-stereo audio device, a portable CD player, or a PC sound card to a multimedia speaker. Additionally, it can be used to connect headphones and earphones to a computer. The blue port is for MP3 players and DVD players. The pink port is for connecting microphones. The green port is used to connect computer speakers and headphones.
When you wish to connect universal devices or personal computers, you use a USB (Universal Serial Bus) cable. Its main use is for short-distance digital communication. Digital data can be transmitted using a USB cable. These days, you use a USB cable to charge devices like Bluetooth speakers, trimmers, smartphones, Kindles, and more. USB cables also allow for direct connections between two devices. All the peripheral devices of a computer system can be connected using a USB cable.
A power cord, or a connector, is a cable containing one or more wires which are covered in a plastic covering and which connect your computer to a power source. Typically, a computer has two main types of cables: data cables and power cables. The cable that provides communication between devices is the data cable. Any cable that provides power to your computer is a power cable.
Firewire, or as it is known in some circles, IEEE , is a common type of connection for a lot of electronic devices like printers, scanners, digital video cameras, external hard drives, etc. These cables are hot-swappable, which means that neither the main devices nor the computers the firewire devices are connected to need to be shut down before they are disconnected or connected. Firewire supports something called plug-and-play, which means that an operating system will automatically detect the device when it’s plugged in and will ask to install a driver if need be.
Given above is a brief introduction to only a few types of desktop cables a computer system would require. There are cables that only transmit audio signals, there are those that only transmit video signals, there are old tech cables that don’t give you the best quality but are still commonly used, and there are new tech cables that give the best speed. There are multiple cables you can go for your specific requirements.
Before you invest in any device which can be considered a peripheral device to your primary system, do thorough research on the cables you may require. Cables have the power to make or break the connection. A good, suitable cable goes a long way.
SF Cable stocks all of the cables mentioned above and we can guide you in choosing what best matches your requirements.
The Complete Guide to Computer Cables and Connections
There are relatively few computer components that can function without the correct cables and connectors. With the right accessories, you can make the most of every aspect of your digital setup while ensuring that you can get everything up and running quickly and efficiently. That’s why we’ve compiled the complete guide to computer cables and connections below.
USB
Many modern devices use a USB port in some capacity. Virtually all computer peripherals such as keyboards, mice, external hard drives, mics, and printers that aren’t wireless will use these cables to make a connection. Furthermore, you can also use USB cables to charge a range of devices, such as mobile phones, or transmit files from one device to another.
USB-Type A
USB-Type A is the most common type of USB port you’ll find, and they feature an iconic but straightforward rectangular shape. This type of port may support USB-2.0 or USB-3.0 speeds, according to the hardware. Although this USB type may not have its own visual standard, you can use a universal docking station or adapter featuring DisplayLink to connect to displays.
USB-Type C
In the upcoming years, USB-Type C is poised to overtake all other USB types and is already the dominant connection on many modern devices, especially slim laptops. The cable connector is significantly thinner than its USB-A equivalents, and it’s entirely reversible, so you’ll never input the wrong side. To their credit, USB Type-C ports can accommodate a variety of standards, but not all of them provide the same performance.

HDMI
The HDMI platform enables a port to transmit high-resolution digital video, theater-quality sound, and device instructions over an HDMI connection using just a single HDMI cable. Most HDMI cables come in three sizes: standard, mini, and micro. Each one can handle the HDMI specification’s video quality and functionality.
Standard Type-A
A Standard (Type-A) connector is the most prevalent HDMI connection. Virtually all modern televisions, gaming consoles, streaming devices, and computers feature these 19-pin connectors to send and receive HD-quality audio and video.
Mini Type-C
Mini HDMI connections (Type C) also feature 19-pins and provide the same functionality as their full-sized counterparts but are much smaller. You’ll typically use these cables with portable devices such as DSLRs and tablets due to their compact design.
Micro Type-D
Micro HDMI (Type D) might be the smallest HDMI connection, roughly half the width of the Mini HDMI connector, but it still has every one of the capabilities of the larger cables. You’ll commonly use Micro HDMI with lightweight, mobile devices such as smartphones.
DVI
DVI (Digital Visual Interface) is immensely helpful for connecting video sources to monitors. They produce high-resolution pictures, and you often find them in CRT displays. The interface can accommodate digital and analog video signals via a single DVI cable.
Types of DVI Connectors
You can divide DVI connections into three categories: DVI-A (analog), DVI-D (digital), and DVI-I (integrated; analog and digital). Both DVI-I and DVI-D connections feature two data speeds, designated as single-link and dual-link, respectively. Each link type has a maximum data rate that guarantees data flow can occur between the video card and monitor without corruption.
Ethernet
While many people use Wi-Fi for convenience, you need an Ethernet cable to achieve the highest speeds. Ethernet cables are the physical connections between your computer and your router or modem.
Hardwiring your Internet connection has the advantage of being speedier and more reliable than depending on wireless signals. Furthermore, you won’t have to fret about abrupt reductions in Internet speed since walls or other structures won’t block your Wi-Fi signals. Coaxial, twisted pair, and fiber-optic cabling are the three most popular forms of Ethernet cabling.
Coaxial
A coaxial cable features an inner conductor extending right through the middle. This cable is resistant to any outside interference because of an insulating layer covering the conductor, further enclosed by another conducting shield. This cabling is available in two varieties: Thinnet and Thicknet. The maximum transmission speed for both kinds is 10 Mbps.
Twisted-Pair
Twisted-pair cables are composed of four pairs of wires. The wires wrap around each other to protect from outside interference and minimize any crosstalk. You can commonly find this type of Ethernet in modern LANs (Local Area Networks).
Fiber-Optic
Fiber-optic cables use optical fibers that send their data in light signals. Each cord is encased in a cladding material while the inside has strands of glass wires. This type of Ethernet connection’s most prominent advantage is accommodating exceptional cable lengths without worrying about electromagnetic interference.
DisplayPort
DisplayPort is a digital interface that allows you to send video and audio via a single cable. It can connect a monitor to a data source, such as a graphics card, and transmit the audio and video to the display screen. While comparable to HDMI, it has a significant advantage in that it is the only technology that can concurrently handle high resolutions and fast refresh rates.
VGA
VGA is the abbreviation for Visual Graphics Array. The cable connects the CPU to the monitor and transmits a video display. It is generally blue and comprises a cord and a connector on either end. The VGA cable has one endpoint that connects to the graphics card on the motherboard and another end that connects to the monitor screen.
It is an electrical connection consisting of three rows of 15 pins. In the world of electronics, you can use a VGA cable in many ways. For example, you can use it as a connector for many different devices such as laptops, TVs, video cards, and many other electronics.
PS/2
You use a PS/2 cable, also referred to as the personal system cable, to connect to a computer’s mouse or keyboard port. The PS/2 cable has a 6-pin connection that complements the openings in the port of a compatible device.
3.5 mm Jack
The 3.5mm audio jack is the most popular format for audio. You’ll find it present on most computers, phones, and tablets. Although older devices may feature two audio ports for microphones and headphones, most modern devices combine the two into a single connection.
3.5mm cables carry analog, mono, or stereo signals. The jacks can also transmit mics and other peripherals. Line-in refers to the sound card’s related inputs, whereas line-out refers to the headphone ports.
Power Cords
Computer power cables, also known as power cords, supply electricity to electronic devices and computers. Generally, these cables work by providing the necessary voltage for the device to operate. You can refer to them as AC adapters for laptops.
