how serial data transmission can be faster than parallel data transmission ? But lets see what it means..
To be with basics , At a given frequency Parallel data transmission is better than Serial data transmission. With parallel transmission , for one clock cycle we can transfer 1 byte but only one bit with serial data transmission.
But we can not use parallel data transmission at high frequency. High frequency will cause data lost , data corruption and synchronization issue . So it may need to transmit the data and finally data rate will be limited.
If we use high frequency for serial data transmission , we can achieve higher data rate because data will be transmitted at only one line . so there is no synchronization and stability issues.
This is the reason SATA AHCI interface makes faster than PATA. In latest technology we use only SATA AHCI.
SATA can run at lower power compared to PATA due to no of pins are less.
So , latest serial data transmission can be called it as High Speed Serial Data Transmission .
One more example is PCIe is faster than PCI.
PCIe is a high speed serial computer expansion bus.
