Parallel port and serial port ppt

A parallel port is a type of interface found on computers (personal and otherwise) for connecting peripherals. The name refers to the way the data is sent; parallel ports send multiple bits of data at once, as opposed to serial interfaces that send bits one at a time. To do this, parallel ports require multiple data lines in their cables and port connectors and tend to be larger than

Well, that's it. The above is not limited to the parallel port. You can use it with any sort of interface that uses a standard I/O port. Of course, this code would not be ideal in controlling the serial port, as a lot of low level coding would be necessary. For example, to read bit 5 of port 888, you would use: Bit5Variable% = BitStatus%(888, 5) A parallel port is a type of interface found on computers (personal and otherwise) for connecting peripherals.

16 Types of Computer Ports and Their Functions A computer port is also called as a Communication Port as it is responsible for communication between the computer and its peripheral device. Generally, the female end of the connector is referred to as a port and it usually sits on the motherboard. In Computers, communication ports can be divided into two types based on the type or protocol used for communication. They are Serial Ports and I/O Interfaces - utica.edu I/O Interfaces Objectives In this chapter, you will:-Learn about serial, parallel and USB ports-Learn how UART chips work-Get the details on the new USB 2.0 standard-Learn about IEEE-1394 - aka Firewire I/O Interfaces The adapter interface is a way to connect one piece of hardware to another PS/2 Serial Ports USB •Parallel Ports use a DB25-pin, female connector Serial Ports The asynchronous Why Is Serial Data Transmission Faster Than … Some things like PCI Express do the best of both worlds, they do a parallel set of serial connections (the 16x port on your motherboard has 16 serial connections). By doing that each line does not need to be in perfect sync with the other lines, just as long as the controller at the other end can reorder the “packets” of data as they come in using the correct order. The How Stuff Works

Using Parallel Ports to Control Devices - Open …

Parallel port is a parallel interface for connecting an external device such as a printer.Most personal computers have both a parallel port and at least one serial port.. PC Parallel Ports. On PCs, the parallel port uses a 25-pin connector (type DB-25) and is used to connect printers, computers and other devices that need relatively high bandwidth.It is often called a Centronics interface Embedded Systems/Serial and Parallel IO - … Data can be sent either serially, one bit after another through a single wire, or in parallel, multiple bits at a time, through several parallel wires. Most famously, these different paradigms are visible in the form of the common PC ports "serial port" and "parallel port". Early parallel transmission schemes often were much faster than serial schemes (more wires = more data faster), but the Port Devices - Neurobehavioral Systems If you would like to use a parallel port not detected automatically by Presentation, click the "Add" button, select "Parallel Port" as the type, and enter the "LPT" number assigned to the port by Windows. After adding the port, the "Address" field in the "Properties" box will be editable. You should set this value to the start of the "I/O Range" reported for the port by the Windows device

Why Is Serial Data Transmission Faster Than … Some things like PCI Express do the best of both worlds, they do a parallel set of serial connections (the 16x port on your motherboard has 16 serial connections). By doing that each line does not need to be in perfect sync with the other lines, just as long as the controller at the other end can reorder the “packets” of data as they come in using the correct order. The How Stuff Works CENTRONICS interface and Parallel Printer Port LPT Today the parallel port in the PC environment is almost no more used, but this doesn’t happen in the industrial fields. For the connections, especially for the printers, now are commonly used other communication standard as the USB, that is a multifunction serial communication. The LPT allows the connection of many different peripheral devices and it transfers 8 parallel bits with the TTL Beyond Designs - PC Parallel and Serial Port … During our years of developing PC serial and parallel port interfaces we encountered a need for simple, yet robust utility programs that could be used to exercise and test these ports. Back in the DOS days, we used ProComm for serial ports. With the advent of Windows, we needed something that would give us direct access to the port signals. We developed VBHexTerm for use with the serial port

03/02/2013 · Port 2 pins are momentarily changed by the address control signals when supplying the high byte of a 16-bit address. Port 2 latches remain stable when external memory is addressed, as they do not have to be turned around (set to 1) for data input as is the case for port 0 . Port 3 . Port 3 is an input/output port similar to port 1 . The input
