Difference between SSD and HDD
CD ROM / DVD ROM
CD: Compact Disc
DVD: Digital Versatile Disc
Video Card
Known as Graphics Card
Function:
Contains the memory and other circuitry necessary to send
Information to the monitor for display on screen.
Sound Card
Known as Audio Card
Attached to the ISA or PCI slot on a motherboard
to enable the computer to input, process, and deliver sound.
Cables of Computer
USB Cable
Universal Serial Bus Cable
HDMI Cable
High Definition Multimedia Interface
Transfer high definition audio and video

SATA Cable
SATA: Serial Advanced Technology Attachment
Function:
To connect a computer's host bus adapter to storage devices
such HDD, SSD
Difference between SATA Power and Molex Power?
Molex is an old technology that powers most of your internal components. Molex power
has four pins on the connector and four wires.
Talking about SATA power cables, these are L-shaped cables with 15-pins on the
connector. However, we can only see five cables in the SATA wire.
Ethernet Cable
Provide Internet Connection
Connect device to a network
5 mm Audio Cable
Transmit audible signals such as voice and music
