Which cables are used to connect computers?
TYPES OF CABLES AND THEIR USES1. VGA Cable Show Also known as D-sub cable, analog video cable Connect one end to computer monitor, television (PC input port) Connect other ends to the VGA port on the computer (see image below)
Connect one end to the computer monitor Connect other ends to the DVI port on the computer (see image below) However, there are 2 types of DVI, DVI-I, and DVI-D.
Connect one end to computer monitor, television Connect other end to HDMI port on computer/laptop (see image above) Note: If you’re hooking up television to your computer, then we would recommend that you use an HDMI cable as your PC cable connection since it is able to transmit both display and sound – So you can not only use your TV screen as a monitor but also make use of your TV speakers to play PC audio. There are different sizes for the HDMI to HDMI cable they include; 1.5M, 1.8M, 3M, 5M, 10M, 20M, 30M, and 50M.
Connect one end to: PS/2 keyboard, PS/2 mouse Connect other end to: PS/2 ports on computer (see image below)
Also known as RJ-45 cable Connect one end to: router, network switch Connect other end to: Ethernet port on computer (see image above)
Also known as phone connector (since 3.5mm jacks are often found on mobile phones too) Connect one end to: computer speakers, 3.5mm headphones, 3.5mm microphone Connect other end to: audio ports on computer (see image below use Green socket)
USB 2.0 USB 3.0 For USB computer cable connections, there are two popular formats: USB 2.0 and the newer USB 3.0 How to tell USB 2.0 and 3.0 cables apart: USB 3.0 cables have a blue tip, and sometimes you can find a SS “Super Speed” label on it. Since USB was intended to be the one computer cable connection to replace them all, it’s no surprise that the possible uses for a USB port are quite mind-blowing. For this computer cable guide, we have listed its more common uses below: Connect one end to: USB device
Connect other end to: USB ports on computer (see image below) How to tell USB 2.0 and 3.0 ports apart: USB 2.0 ports have black tips while USB 3.0 ports come with blue tips. See image below: USB 3.0 is backwards-compatible… meaning that you can connect a USB 2.0 device to a USB 3.0 port and vice versa (but the USB 3.0 devices hooked up to a USB 2.0 port will perform at lowered rates) There are also USB cables which connect new external backup drives (see below), these are described as USB-A to Micro-B
Connect one end to: AC power socket Connect other end to: power supply unit (see image below), computer monitor Note: Always turn off your power supply unit (with the 1-0 switch at the back) before connecting a power cord to it.
Mostly seen on laptops and Apple Macs these cables are high speed and are capable of carrying Data, video and other information. There are 2 current types of Thunderbolt, the older version Thunderbolt 2 is seen below but this can also be confused with Mini Display ports as they look identical and only visual difference is the picture beside the port. Thunderbolt 2 (left) has a lightning symbol and carries Data and video. The Mini Display Port (right) will only carry Video. And Thunderbolt 3 also known as USB-C on Apple Macs.
Display Port is the best to use if you require a fast, high-resolution image. 11. FIBER OPTIC CABLEWhen it comes to a faster Internet – Electricity and light are 2 of the fastest things that we use to transmit data. But sadly, copper wires are reaching the technical limitations for data transfer. The newer generations of “serious networking devices” are skewed towards using fiber optic cables for ultra-fast data transfers. 12. POWER CORDSThe power cords of a computer comply with the IEC standards, which is the same as almost all of our other household appliances. Here are 3 of the common power plugs that you see in computers:
13. TELEPHONE CABLEWell, you should know this from your home telephone, and it is also connected to AIO printers to send out faxes. Call this RJ11 if people want to get technical. 14. LIGHTNING CABLELightning is the latest generation of iPhone/iPad connectors, and it is specific to Apple devices only. Well, the certain fruit company definitely has no love for the mainstream standards. 15) PARALLEL CABLEOnce upon a time in the stone age of computers, we connect printers to computers using these parallel cables. They are built like tanks and wouldn’t even budge if you yanked hard at it. Of course, they could not handle large amounts of data fast enough and have been totally phased out. 16) SERIAL CABLEThe serial connectors are cousins to the parallel connectors – As some of you may have noticed, yes, these are the ancestors of the USB. 17) FIREWIRE (IEEE 1394)The FireWire is Apple’s so-called early version of the USB – But this is not compatible with USB devices. While there are a couple of gadgets made for the FireWire, it was never too popular and was overshadowed by USB. 18) USB to RS232 USB to RS232 Converter Cable connector attaches to the RS-232 port of a data logger or peripheral, such as an MD485 Multi drop Modem or RF401-series Spread-Spectrum Radio. Alternatively, the RS-232 connector can attach to an SC32B interface, which attaches to the CS I/O port of a data logger via the SC12 cable. 19.) Console Cable (RJ45 to DB9) Also known as RJ45 to DB9, rollover cables and management cables There are two that are used more commonly than the rest, mostly because of the frequency with which you will see these different connectors. USB to RJ45 It is arguably the most modern console cable. It streamlines your communication via USB. It goes seamlessly from the console port on the rj45 port to a standard USB port on a PC. |
