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.
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
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 >
A motherboard links the different components within a computer to allow communication between all the hardware components. It holds the system memory, expansion slots, networking systems, audio, input/output systems and the central processing unit. The motherboard is the central component of a computer, and the computer can not run without it. There are huge variations in motherboards in terms of size, design, compatibility, cases and power supply.Full Answer >
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 >
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 >
