Sniffers monitor network data . A sniffer can be a self contained software program or a hardware device with the appropriate software or firmware programming. Sniffers usually act as network probes or "snoops." They examine network traffic, making a copy of the data without redirecting or altering it. Some sniffers work only with TCP/IP packets, but the more sophisticated tools can work with many other protocols and at lower levels including Ethernet frames. here is a simple figure of network cable.   Sniffers were tools used exclusively by network engineers.

A computer basically performs five major operations or functions irrespective of their size and make. These are 1) it accepts data or instructions by way of input, 2) it stores data, 3) it can process data as required by the user, 4) it gives results in the form of output, and 5) it controls all operations inside a computer. 1. Input: This is the process of entering data and programs in to the computer system. You should know that computer is an electronic machine like any other machine which takes as inputs raw data and performs some processing giving out processed data. Therefore, the input unit takes data from us to the computer in an organized manner for processing. 2. Storage: The process of saving data and instructions is known as storage. Data has to be fed into the system before the actual processing starts. It is because the processing speed of Central Processing Unit (CPU) is so fast that t...

It is   embedded   as a part of a complete device that inculdes hardware and mechanical parts to acheive the tast of embedded system. By contrast, a general-purpose computer, such as a   personal computer   (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems control many devices in common use today. eg: Washing Machines, Micro Waves etc. Embedded systems contain processing cores that are typically either microcontrollers or   digital signal processors   (DSP).   The key characteristic, however, is being dedicated to handle a particular task. Since the embedded system is dedicated to specific tasks, design engineers can optimize it to reduce the size and cost of the product and increase the reliability and performance. Some embedded systems are m...
