Need of Ports

Direct Cable connection is Difficult toimplement.

Multiple wires are used tocommunicate

Easy to implement bigger network

Physical shapes

Port physically may be of two types:

Male

Female

Male ports usually joined to wire and

have pin shaped.

Female ports usually joined by device

and have hole shaped and fits the male

Benefits of male femaleconnectors

Male female ports are stronglycoupled ports there for our

connection becomes more reliable

Small size

Low cost

Types of ports

There are basically two types ofports.

Serial PortParallel Port

Serial Port

Serial ports are universal I/O ports.They are available on almost every

computer.

Serial ports are slow, but they are

flexible.

Serial ports can be used for terminal

connections, printer connections,

Complication with serialport

You must set the communication speed(baud rate) of the device and the serial port.

You must set the correct form of paritychecking on the device and the serial port.

You must set the number of stop bits to beused on the device and the serial port.

Parallel Port

Parallel port is a simple andinexpensive tool for building

computer controlled devices andprojects

The parallel port is often used in

Computer controlled robots,Atmel/PIC programmers, homeautomation, ...etc

The simplicity and ease

Ethernet

Introduced in 1980

Ethernet has largely replacedcompeting wired LAN technologies.

Data rates varies from 10 megabitsper second, to 100 gigabits persecond.

IEEE 1394 Interface

The IEEE 1394 interface is a serialinterface standard for high-speed

communicationsand isochronous real-time datatransfer

Image data transfer up to 32MByte/s (400 Mbit/s interface)


13/174/26/12

PS/2 Connector

The PS/2 connector is a 6-pin Mini-DIN connector

Its name comes from the IBMPersonal System/2 seriesof personal computers

Introduced in 1987Serial data at 10 to 16 kHz with 1

stop bit, 1 start bit, 1 parity bit (odd)

VGA

A VGA connector is a three row 15pin connector.

Introduced in 1987

Widely used for Display devices


15/174/26/12

USB

Abbreviation for Universal Serial bus

Introduced in 1990

USB 1.0 up to 12 Mbps

USB 2.0 up to 480 Mbps

USB 3.0 up to 5 GbpsEasy to implement and Easy to use

Smaller Size

TRS

TRS name is made of conducting partof plug i.e. Tip, Ring and Sleeve

Introduced in 1907

Used for only audio communication

Data rate is poor.
