Serial advanced technology attachments (SATA) work by transmitting data between a motherboard and hard drives through a seven-pin cable that sends information twice as fast as previous technology, according to About.com. A single high-speed serial wire now inhabits most computer systems instead of a parallel bus system that incorporated 40-pin wires or 80-pin wires.Continue Reading
SATA cables transmit data at a higher clock rate than parallel bus systems. A clock rate is how fast a CPU executes instructions, therefore SATA cables handle faster CPU speeds than parallel cables. SATA lines transmit data up to 3 gigabytes per second to keep up with faster CPUs.
Serial wires use two lines for sending data and two lines for receiving data. Three lines are ground wires, which adds up to the seven wires and pins in a SATA cable. Serial wires take up less space than parallel ones, thereby making more space for hardware in desktop and laptop computers. SATA cables have allowed computer hardware to get smaller and faster as compared to parallel systems.
Older parallel systems were replaced because processor speeds increased. When speeds increased, interference in the lines also increased. Serial transmissions use just one line instead of several parallel lines, so interference is minimal.Learn more about Computers & Hardware
The dual shield Rg6 and quad shield Rg6 cables themselves are exactly the same, but the Quad shield housing offers more protection against static inference than the standard Rg6 cable. In instances in which there should be little to no signal interference, a dual shield Rg6 will work just as well as the Rg6 Quad shield.Full Answer >
Apple frequently uses proprietary cables for its mobile devices, namely the Apple 30-pin dock connector and the Lightning connector cable. Apple helped develop the Thunderbolt port and used it in desktops and laptops since 2011 but may be turning toward standardized USB Type-C connectors, as of 2015.Full Answer >
There are several ways to watch television on a laptop, including paid streaming sites, downloaded applications from cable and satellite companies and connecting HDMI or other cables to your television. Using HDMI or S-Video cables is more involved, but allows the television content to broadcast seamlessly on a laptop.Full Answer >
As the name indicates, a motherboard is an essential part of computer equipment that allows different components of the computer, including the hard drive, memory cards and processors, to connect and communicate with each other. The motherboard also allows the different computer components that are plugged into the motherboard receive power and are typically made from printed circuit boards, or PCB, and have multiple slots for things like video and sound cards. In many cases, a computer's motherboard will have empty slots that allow the user to expand his or her computer's capabilities through adding new equipment to the motherboard.Full Answer >
