Branch (2012)‚ in his article What is a Ping Sweep he says “A ping sweep‚ also called an Internet Control Message Protocol (ICMP) sweep‚ is a diagnostic technique used in computing to see what range of (IP) addresses are in use by live host‚ which are usually computers”. Ping sweeps are not unusual‚ they are often used by administrators in diagnosing network

What is the difference between Serial transmission and parallel transmission? Answer: Digital data transmission can occur in two basic modes: serial or parallel. Data within a computer system is transmitted via parallel mode on buses with the width of the parallel bus matched to the word size of the computer system. Data between computer systems is usually transmitted in bit serial mode . Consequently‚ it is necessary to make a parallel-to-serial conversion at a computer interface when sending

Authentication Protocol for Vehicular Ad Hoc Networks ABSTRACT Vehicular Ad Hoc Networks (VANETs) adopt the Public Key Infrastructure (PKI) and Certificate Revocation Lists (CRLs) for their security. In any PKI system‚ the authentication of a received message is performed by checking if the certificate of the sender is included in the current CRL‚ and verifying the authenticity of the certificate and signature of the sender. In this paper‚ we propose an Expedite Message Authentication Protocol (EMAP)

United Kingdom’s climate change protocol will be reported and verified through a variety of procedures. Most dominantly‚ England is a proud member of the Kyoto protocol‚ which monitors progress of all the countries involved. The program evaluates all emissions of GHG from each country to find where monitoring of the gases is most necessary. Precise records of emission trading are recorded to ensure the target goal is within reach. To ensure the rules of the protocol are followed‚ the UN Climate

Data transmission‚ digital transmission‚ or digital communications is the physical transfer of data (a digital bit stream) over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires‚ optical fibres‚ wireless communication channels‚ and storage media. The data are represented as an electromagnetic signal‚ such as an electrical voltage‚ radiowave‚ microwave‚ or infrared signal. Data representation can be divided into two categories: Digital
