For your computer to function properly, you need to know what cables are inside the computer’s case. USB cables are the most popular, but not only them
When assembling your computer, the hardest part is definitely getting all the cables in their place. Components of the computer must be connected to the motherboard for everything to work properly. Untangling the hard drive and fan cables is not easy at all.
You also need to add Ethernet cables to connect the router to the network card and the HDMI cable to connect the video card to the monitor. Unless you are a computer expert, untangling all these cables can be very complicated and can lead to computer crashes. That is why it is worth knowing every single “cable” that is used to connect computer components, so that you do not have problems with fixing minor faults.
USB cables
The most common cables are USB cables, which are used to connect other devices to the computer and to charge the smartphone. Universal Serial Bus cables are undoubtedly the most easily recognized and used by users. They are very flexible and above all can be found almost anywhere. Note, however, that not all USB cables are created equal. What’s the difference between the different types of USB cables? The baud rate changes. The USB 1.0 port can transfer data at speeds up to 12 Mb / s. USB 2.0 can transfer data at speeds up to 480 Mb / s and is backwards compatible.
USB 3.0 can transfer data at much faster speeds up to 4.8 Gb / s. This port is also backward compatible. The micro and mini variants are used in small electronic devices and often in laptops.
DVI
The Digital Visual Interface cable is the direct successor to VGA. DVI connectors are divided into three variants, each of which has different technical properties. DVI-A enables the transmission of analog signals and is useful in the case of inferior CRT and LCD monitors. In turn, DVI-D is a technology that is used to transmit digital signals. Conversely, DVI-I is useful for transferring both digital and analog signals.
HDMI
This connector has been popularized over the years by game consoles and televisions. It is a fairly new technology and therefore not compatible with older electronic devices and is highly dependent on very good signal quality. There are four types of HDMI cables. There are Type A, the most popular and widely used. Then type B, type C (mainly used in cameras and camcorders) and finally type D.
IDE
These are very popular connectors that not everyone knows about. They are mainly found in the connections between the motherboard and external storage devices. IDE stands for Integrated Drive Electronics.
SATA
The latest hard drives use SATA ports, short for Serial Advanced Technology Attachment, instead of IDE ports. Where did this change come from? Because SATA ports allow much faster data exchange than IDE cables. Almost all motherboards are now SATA compatible.
ESATA
As the name suggests, ESATA (External Serial Advanced Technology Attachment) connectors are an improvement over SATA cables. The main differences are in the compatibility. The ESATA connector allows you to connect devices such as external hard drives and optical drives. Additionally, the data transfer speed is better.
FireWire
The purpose of FireWire ports and cables is similar to USB: transferring data in the shortest possible time. They are very common in devices such as scanners and printers. It must be admitted, however, that FireWire has never been as popular as USB. There are two types, one with a maximum speed of 400Mbps and the other with a speed of 800Mbps.
Ethernet
Ethernet cables are used to create local networks.
In most cases they are used to connect routers and computers. There are currently three versions available. The basic model is Cat. 5, which offers speeds from 10 Mb / s to 100 Mb / s. Then we have Cat 5e, short for Cat 5 Enhanced, which enables faster data transmission, up to 1000Mbps. And finally, Cat. 6, which reaches speeds of up to 10Gb / s.
