Introduction

The Parallel Port is the most commonly used port for interfacing home made projects. This port will allow the input of up to 9 bits or the output of 12 bits at any one given time, thus requiring minimal external circuitry to implement many simpler tasks. The port is composed of 4 control lines, 5 status lines and 8 data lines. It's found commonly on the back of your PC as a D-Type 25 Pin female connector. There may also be a D-Type 25 pin male connector. This will be a serial RS-232 port and th ....etc

Introduction
The PC parallel port is a powerful platform, though inexpensive, for implementing projects dealing with the control of real-world peripherals. It can be used to control the printer as well as household and other electrical appliances.
The computer program included as part of the project controls relays through the interface circuit, which, in turn, switch the appliances ‘on’ or ‘off’. The parallel port has 12 outputs including 8 data lines and 4 control lines.
The hardware circuit developed ca ....etc

LED BRIGHTNESS CONTROLLING USING SERIAL PORT




Interfacing with pc

Interfacing is done using RS232 DS-9 port which is connected to pc & microcontroller.
On port 3,at p3.0 & p3.1 the input signal is received.
TXD,RXD pins are also used in interfacing.


Sending signals from pc

To send signals from pc we need to make a software using vb .net .This signals will vary from 0 to 255.As per this signals the PWM will vary by duty cycle in microco ....etc

DUAL PORT FIFO

Abstract:- The dual port FIFO is now a standard building block in most designs, especially in the area of communications where it is used frequently for packet work. Although very useful in its basic form, the standard FIFO does lack two attributes; autonomy and cascadability. Unfortunately you cannot simply connect two FIFOâ„¢s together, as shown below, and expect them to automatically transfer data ....etc

Online Port Scanner

Online Port Scanner is a web user control in C# NET 2. The web user control will later be placed within an ASP.NET page. The purpose of the control is to offer admin a control panel where he can add port like http 80, FTP 21 and so on. Next will be to offer user a form where he/she can start a scan towards own firewall or computer. The purpose of the test is to display ports that are open or exposed to threats.

The port scanner will also have a statistics module that show what ports are most often found open. How many ....etc

Real Time Port Scan Detection for Internet Backbone

Malware of many different varieties continue to spread through todayâ„¢s Internet at an alarming rate and volume. Port scanning, along with email and web page phishing, are the major channels of such propagation. This perpetual and unwanted scanning traffic is often aimed at discovering and infecting vulnerable hosts with viruses, leading eventually to botnets and criminal activities To understand, detect and eliminate such traffic is a vital part of enhancing Internet security.
