Which interface standard is commonly used for internal hard drives?

• A. SATA
• B. RJ11
• C. ROM
• D. RAM

Answer: (A)

SATA, or Serial ATA, is the interface designed for connecting internal storage devices to the motherboard. It uses thin cables and supports fast serial data transfer, making it the standard for internal hard drives in most desktops and laptops. SATA has evolved through faster generations (SATA I, II, III) and often supports hot-swapping, which means drives can be swapped without powering down in many setups. The other options don’t fit: RJ11 is a telephone-style connector, not used for storage; ROM refers to read-only memory, not a drive interface; RAM is volatile system memory, not a storage interface. So SATA is the commonly used interface for internal hard drives.
