Bit
Binary Digit a single “bit” can store one of two values: 1 or 0
Nibble
4 bits i.e. 0110
Byte
8 bits i.e. 11010101
“bps”
Bits per second
1000 bits
1 Kilobit (1Kb)
b =
bits
B =
Bytes (8x as many bits)
1 million bits =
1 Megabit (Mb)
1 million bytes =
1 Megabyte (MB)
1 billion bits =
1 Gigabit (Gb)
1 billion bytes =
1Gigabyte (GB)
1 trillion bits =
1 Terabit (Tb)
1 trillion bytes =
1 Terabyte (TB)

HDMI:
High Definition Multimedia Interface (most widely used)
HDMI Category 1 (Standard):
used for video content. supports 1080p and 60 hertz
HDMI Category 2 (High Speed):
has great length of distance and high resolution allows up 4k/8k resolution and higher refresh rates 60/120/144 hertz. (premium high speed of 18Gbps and ultra high speed of 48Gbps)
HDMI Digital Content Protection (HDCP)
Allows a device to validate the connection i.e. ROKU
Display Port Interface (DP):
developed as a competitor to HDMI to avoid royalty fees and has all the same capabilities as HDMI
DVI: Digital Video Interface
supports analog and digital outputs
What are the 3 types of DVI and what do they do?
- DVI-A (Analog) only supports analog signals
- DVI-D (Digital) only supports digital signals
- DVI-I supports both digital and analog signals
VGA: Video Graphics Array
uses a 15-pin standard analog video interface port
Thunderbolt
acts like a display interface and can do data transfer
Thunderbolt 1 and 2 connector
is backwards compatible with Display Port(DP) they look identical to DP but are signified by a small lightning bolt
Thunderbolt 3:
physical interface that uses the same port as USB-C. Port fully compatible with USB-C however USB-C ports do not always support Thunderbolt 3
Serial:
can connect one device at a time
Thunderbolt 3 length limitation
maximum of 1.6ft which provides up to 40Gbps
Parallel:
can connect multiple devices at once
Thunderbolt 1 and 2 :
uses DP type connector
Thunderbolt 3 and 4 :
uses USB-C type connector
Lightning Cable:
specific propriety connector created by Apple for mobile devices has either USB-C or USB-A on other end of cable
SATA Cable: Serial Advanced Technology Attachment
Standard method of connecting a storage device to a motherboard.
SATA 7-Pin Data Cable
Performs the data transfer and does not supply power.
SATA 15-Pin Power Connector
Provides the power and does not transfer data.
SATA1:
supports speeds of up to 1500Mbps(1.5Gbps)
SATA2:
supports speeds of up to 3000Mbps(3Gbps)
SATA3:
supports speed of up to 6000Mbps(6Gbps)
External SATA (eSATA):
