We are moving towards an age where people are using laptops and tablets more than the computer system. But we have yet not given up using a computer system. There are certain professions that still prefer a system like IT companies, government offices, schools, etc
Talking about computer systems, one of the key challenges that most of you might have faced is during its setup. For a hassle-free setup, the most important thing to understand is computer cables. There are a lot of cables that run inside and outside the CPU. It is important to know them well in order to get the best quality output.
Here we have discussed seven cables from which some are used inside while some are used outside the CPU for different purposes. Let us understand it one by one.
Bi-directional Printer Cables
A bi-directional cable means it can send real-time information from computer to printer and vice versa. Such communications enable monitoring printer status and print job scheduling even if it is distributing print jobs from multiple computers to multiple printers. Nowadays, most printers allow turning off the bi-directional option from the computer or from printer drivers. This way the printer gets some extra buffer resources for status checking, communication, and error reporting.
DVI Cables
Digital Visual Interface (DVI) is used to connect displays with the CPU. DVI cables deliver better picture quality compared to VGA cables. So DVI took the place of VGA cables. The main intention behind developing these cables was to transmit both digital and analog signals at industry standards.
D-Subminiature Cables
D-subminiature or D-sub or DB connectors are commonly used in communication. The name is derived from the fact that its shape resembled the shape of the letter D. It was developed by Cannon in the 1950s. The connector consists of two parallel rows of pins. Day by day it is replaced by USB connectors, but still, there are devices that use only DB connectors like computers, projectors, medical devices, etc. As these connectors have screws for the enclosure which help to create a solid mechanical connection.
DisplayPort Cables
DisplayPort is to transfer audio and video data over a singular cable. It is something similar to an HDMI cable. It can connect a display and graphics card, laptop, or computer. The resolution and refresh rates are high. DisplayPort has many advantages like strong manufacturing, greater bandwidth, and an explicit feature set. You can also manually set the resolution and refresh rate for the displays.
Firewire
Firewire is a connecting device used for connecting digital camcorders, hard drives, keyboards, digital cameras, etc. Firewire cable was developed by Apple and was the standard feature for many years of Mac computers. In recent years, Macs have been installed with a new interface called Thunderbolt. FireWire devices are also called hot-pluggable which means that without any power, they can be connected and disconnected.
Null Modem Cable
A null modem cable, also known as a cross-over cable, allows a head-to-head connection between two serial devices through their communication ports. It has a length limit of up to 30 feet. It is usually used to connect two computers in the same room for gaming or sending and receiving files.
IDE Cables
Integrated Drive Electronics (IDE) is an electronic interface standard. It defines the connection between a computer's motherboard and a disk storage device. One IDE ribbon cable connects one hard drive and a CD drive to the motherboard. It can connect two hard drives also to the motherboard. For successful implementation, the jumpers must be configured correctly.
Conclusion
Now that you know what cables go inside and outside the CPU, the only thing that remains is to ensure the quality of these cables. It is wise to buy good quality cables from authorized sellers. This way you will save your system from any other damage. To buy these cables online, you just need to search “firewire cables” or “IDE cables” or “Computer cables” and you will find the products with the pricing.
