There is little difference you would need to know about in general, with the major one being the physical difference in that they use entirely different cables.
IDE has a big ribbon cable.
SATA has a smaller serial cable.
If you need to know about bus controllers, you'll be better off taking a course in computer architecture at your local university.

There is really no difference between IDE and SATA hard disks, except in the way they connect to the PC. The SATA connector is simpler and the cable is less fussy.

They use different cables, SATA's supposedly draw a bit less power and run a bit cooler relative to their speed. SATA's theoretically can transfer data much faster than EIDE, but in the real world, the speed difference is not as dramatic as the specs lead you to believe.

Answer:
Enhanced Integrated Drive Electronics (EIDE), also known as Fast AT Attachment (Fast ATA), is an updated version of the Integrated Drive Electronics (IDE) storage interface that works with hard drives and CD-ROM drives. It can shuttle data to and from the drive three to four times faster than the IDE standard (transferring data between 11MB and 16.6MB per second) and can support data storage devices that store up to 8GB more than IDE drives.
SATA (Serial ATA) is a new interface for internal devices such as hard drives, debuting in 2002. Serial ATA, initially having a theoretical maximum throughput of 150MBps, allows better signal timing and higher speeds than the parallel EIDE standards such as Ultra ATA/133/100/66. SATA also enables easier device setup and better airflow within the computer case with less obstructive data cables. Industry analysts expect SATA eventually to supplant EIDE.
Hard drives are running faster as they mature, and the common EIDE (Enhanced Integrated Drive Electronics) interface (connection between the drive and the computer’s microprocessor) won’t be able to keep up for long. Serial ATA (Advanced Technology Attachment) is the answer. SATA sends one bit of data at a time faster than a parallel interface, such as EIDE, can send a group of bits at once. For this reason, some observers now call EIDE parallel ATA, or PATA, to distinguish it from Serial ATA. Other variations of EIDE you’ll encounter are ATA, UltraDMA (direct memory access), IDE, and so on.
But beware - SATA drives use different cables than typical EIDE drives. They require an SATA-compatible motherboard, or an SATA adapter card that fits in a PCI (Peripheral Component Interconnect) slot in your computer. SATA will replace EIDE as the standard interface for hard drives, and later, other devices such as optical drives.

SATA uses a much smaller and different cable and connector. Less obstruction to get in the way of airflow for cooling.

It is the interface and the address lines. Look them up in wikipedia.org for complete description.
