5.3 Networking 5.3.1 TCP/IP stack The TCP/IP stack is shorter than the OSI one: TCP is a connection-oriented protocol; UDP (User Datagram Protocol) is a connectionless protocol. 5.3.2 IP datagram’s The IP layer provides a connectionless and unreliable delivery system. It considers each datagram independently of the others. Any association between datagram must be supplied by the higher layers. The IP layer supplies a checksum that includes its own header. The header includes the source and destination

management and leadership development, team building, and other principles of organizational change in the effort to create positive change within an organization. The first component of this discussion evaluates systems thinking and the application and limitations of systems logic as essential considerations in managerial decision making. Systems thinking is also a technique that manages a process as a whole while understanding that individual pieces of the process can cause an impact. Systems thinking applies

master the subject I have published another paper on A Review Of Low Cost Object Tracking System in IJCSET (ISSN 2231-0711). This paper proposes and implements a low cost object tracking system using GPS and GPRS and GIS using HTTP protocol. A web application is developed using PHP, JavaScript. Working on these, I came to know how we can control the devices using programming skills. Through these, interest towards programming has been infused in

some basic information theory, applied mathematics theory, and things like network topology/design, database design, and the like. IT concerns itself with taking building blocks such as servers, operating systems, network switches, and software applications and creating a whole system to solve a problem (such as creating a sales order handling systems). Computer Science - this is a theoretical field, with emphasis on the mathematical basis which underlies modern programming. That is, computer
