TCP UDP Acronym for: Transmission Control Protocol User Datagram Protocol or Universal Datagram Protocol Function: As a message makes its way across the internet from one computer to another. This is connection based. UDP is also a protocol used in message transport or transfer. This is not connection based which means that one program can send a load of packets to another and that would be the end of the relationship. Usage: TCP is used in case of non-time critical applications. UDP is used for games or applications that require fast transmission of data. UDP's stateless nature is also useful for servers that answer small queries from huge numbers of clients. Examples: HTTP, HTTPs, FTP, SMTP Telnet etc... DNS, DHCP, TFTP, SNMP, RIP, VOIP etc... Ordering of data packets: TCP rearranges data packets in the order specified. UDP has no inherent order as a...

Procedure   oriented programming   (POP) Object oriented programming (OOP) POP emphasis on algorithms (procedure) OOP emphasis on data rather   than procedure. Large programs are divided into smaller programs known as functions. Programs are divided into objects. They have not facility to hide data. They have facility to hide data from outside world. Function can transfer data from one function to another and one form to another form. Objects can communication with each other using functions. It does not have powerful features like operator overloading, inheritance etc. It contains powerful features   like operator overloading, inheritance. For design program it uses top-down approach. For design program it uses bottom-up approach. Examples: C, COBOL, FORTRAN etc. Examples: C++, java Application of OOP o  ...

Science, Engineering, and Technology What is the difference between science, engineering, and technology? How do they interrelate? Here are a few simple ways to distinguish between and relate these fields.  Science : A body of knowledge Seeks to describe and understand the natural world and its physical properties Scientific knowledge can be used to make predictions Science uses a process--the scientific method--to generate knowledge Engineering: Design under constraint Seeks solutions for societal problems and needs Aims to produce the best solution given resources and constraints Engineering uses a process--the engineering design process--to produce solutions and technologies Technology : The body of knowledge, systems, processes, and artifacts that result from engineering Almost everything made by humans to solve a need or fulfill a want/desire is a technology Examples of technology include pencils, shoes, cell ph...
