Air traffic control (ATC) is a service provided by controllers who direct aircraft on the ground and in the air. The main function of ATC systems worldwide is to separate aircraft to avoid collisions‚ to organize and expedite the flow of traffic‚ and to provide information and other support for pilots when able. In some countries‚ ATC may also play a security or defense role (as in the United States)‚ or actually be run entirely by the military (as in Brazil). Air traffic control was first introduced

Traffic accident has been a serious issue in Hong Kong. From 1997 to 2006‚ over 14000 traffic accident cases have been reported each year. The number of cases remained at a high level. In 2006‚ 14849 cases happened causing 144 people died and 18729 people injured. Averaging 40 traffic accident cases take place per day. Traffic accident not only endangers human life but also causes traffic congestion. It brings inconvenience to people. Undoubtedly‚ it wastes the time of road users and also cause serious

Linux evolved into a fully functioning Operating System (OS) with one of its first distributions created by the Manchester Computing Center‚ MCC Interim Linux‚ using a combined boot/root disk (Hayward‚ 2012). Linux luminaries‚ Slackware‚ RedHat and Debian began to rise between 1992 and 1994 as well as the Linux kernel growing to version 0.95‚ becoming the first kernel to run the X Windows System

Linux - The shell ------------------------------------------------- Introduction to the shell The command interpreter is the interface between the user and the operating system‚ hence the name "shell". The shell therefore acts as an intermediary between the operating system and the user thanks to command lines that are entered by the latter. Its role consists in reading the command line‚ interpreting its meaning‚ carry out the command‚ and then return the result via the outputs. The shell

Zone Routing Protocol in Computer Networking (ZRP) Abstract Routing protocols for mobile ad-hoc networks have to face the challenge of frequently changing topology‚ low transmission power and asymmetric links. Both proactive and reactive routing protocols prove to be inefficient under these circumstances. The Zone Routing Protocol (ZRP) combines the advantages of the proactive and reactive approaches by maintaining an up-to-date topological map of a zone centered on each node. Within
