Hardware Ports

Ethernet 1973
Usb (1.0, 2.0, 3.0/3.1) 2000
Audio Port 1878
PS/2 Port 1987
Parallel 1981
Serial 1986
vga 1987
dvi 1999
rs232 1962

History Of Computer Ports
(There's Alot!)
Ethernet
The Oldest Port Is...
?
What do you think is the oldest port?
?
Who invented
the thunderbolt port?
?
What does HDMI stand for?
?
What Is the
Standard
Resolution of
VGA?
Usb (1.0, 2.0, 3.0/3.1) 2000
-Different connectors, A-type or B-type to prevent electrical overloads
-A-type full, B-type vary in size

RS232 compatible port was a standered feature for serial communication, such as modems and personal computers (widespread) until the 1990s
RS232 1962
There Are 2 catagories of computer ports
IEEE 1394
Serial Interface
Parallel Interface
Transfer info one bit at a time
Transfer data from a computer to various devices
Transfer more than one bit simultaneously.
Re-sync's the data once transferred
The Audio Jack
Invented in :
1878
Different Sizes

1/4 inch
3.5mm (most common)
sub mini 2.5mm
Found On...
Pros:
Cheaper to Implement
Easier to Over-Clock
Headphone
Computers/Laptops
Speakers
Instruments (electric guitars)
Phones
Camera's
Cons:
More Expensive (+Pins)
Sync Issues
Pros:
Faster Speeds (In Theory)
Invented :
VGA
Invented:
PS/2
1962
Invented :
1973

Usage:
Defined:
Invented in:
Ethernet is a family of computer networking technologies for local area networks (LANs).
It was commercially introduced in 1980
Cons:
Slower Speeds (In Theory)
How it works
Invented in :
2002
Different Sizes

Type A (standard)
Type C (mini)
Type D (micro)
Found On...
Televisions
Desktops
Laptops
Phones
Cameras
Serial Port
Systems using Ethernet communicate by dividing the stream of data into shorter parts called frames. Each of these frames have a source, a destination, and error-checking data so damaged data can be noticed and re-sent
.

Digital (HDMI) vs Analogue (VGA)
What Is It:
High Definition Multimedia Interface
Creates high-bandwidth connections
Standard connection for High definition video
Ability to carry multiple signals (Parallel) including video and audio (8 channels)
1987
-standard size used on USB Flash Drvies
-Mini size used on cameras
-Micro size on modern cell phones
Standard Output
VGA connectors and cables carry analog component RGBHV (red, green, blue, horizontal sync, vertical sync)
How It Works

640x480
1987
The VGA port won't be around much longer
Use:
Will be rare this year
Manufactures are no longer making them
Better technology is available (HDMI)
VGA(ANALOG) -> HDMI(DIGITAL)
To connect mice and
keyboards before USB
The Future
USB 4.0 - It will be reversible
-Replaced RS-232

Thunderbolt port

Developed by Intel
Electronically identical to Display port
Also transfers electricity
Invented :
2011
How it Works
Thunderbolt combine multiple lanes of data from connected devices called multiplex via one duplex Thunderbolt lane, then de-multiplex's them to be used by other devices such as monitors and peripherals.
Invented:
1994
Use:
Serial Bus Interface
for high speed communications.
Developed by apple
who called it Firewire
(Comparable to USB)
Also known by i.Link
(Sony) and Lynx
(Texas Instruments)
Works Citied:
