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.Know More
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
PCI Express is a hardware protocol that moves data through serial connections that operate as a network. A switch is used to control multiple data connection channels, and each device connected to the PCI Express receives a dedicated communication channel that eliminates problems with data bandwidth bottlenecks. Each connection lane is made up of two pairs of wires that function as a path for the sending and receiving of data.Full Answer >
SATA is a newer technology and affords users technological advances over PATA. PATA and SATA are both types of hard drive connections. PATA stands for parallel ATA, and SATA stands for serial ATA.Full Answer >
The main difference between the IDE and SATA storage connectors is that SATA has a much faster data transfer rate, compared to IDE. SATA connectors usually support transfer rates of up to 6 gigabytes per second compared to only 133 megabytes per second for the IDE.Full Answer >
Two laptops can be connected together using a pair of CAT-5 cables or through wireless connectivity over a network. In most cases, it can be as easy as connecting them using the USB wireless adapters already built into the system without involving a hub, router or even a switch.Full Answer >
