COMPUTER FUNDAMENTALS

Detailed explanation-1: -Serial ATA (Serial Advanced Technology Attachment or SATA) is a command and transport protocol that defines how data is transferred between a computer’s motherboard and mass storage devices, such as hard disk drives (HDDs), optical drives and solid-state drives (SSDs).

Detailed explanation-2: -Hard disk drives are accessed over one of a number of bus types, including parallel ATA (PATA, also called IDE or EIDE; described before the introduction of SATA as ATA), Serial ATA (SATA), SCSI, Serial Attached SCSI (SAS), and Fibre Channel.

Detailed explanation-3: -USB is the most common connection type for external devices, whether external hard drive, thumb drives, flash drives, printers, cameras, all kinds of other devices.

Detailed explanation-4: -IDE and SATA are different types of interfaces to connect storage devices (like hard drives) to a computer’s system bus. SATA stands for Serial Advanced Technology Attachment (or Serial ATA) and IDE is also called Parallel ATA or PATA.

Detailed explanation-5: -Any SATA hard drive has two L-shaped ports: the smaller one is for data connection, while the wider one is for power. Thus, you need two cables per each SATA drive: A SATA data cable is flat, typically red-colored, with small identical 7-pin connectors on each end that have recognizable L-shaped notches.
