physical and tangible components forming a computer are called “Hardware”. It includes not only the computer system but also cables‚ connectors‚ power supply units and peripherals such as Keyboard‚ Mouse‚ Audio Speaker‚ Printer etc. Software: The software refers to the program that instructs the computer what to do. Or The term Software refers to non – physical elements of a computer system. Software makes the hardware usable. Such as Ms. Office‚ Corel Draw‚ Oracle etc. Q - 3) Define a programming

Systems‚ Topic 1 System - collection of parts working together‚ forming a functioning whole. Three types of systems Open System - exchanges matter and energy with its surroundings‚ ex. Ecosystem * energy from sun‚ converted to sugar by plant‚ plant is eaten by a bug - energy exchange * animals eating each other - matter exchange Closed system - exchanges energy with its surroundings but not matter‚ ex. Biosphere 2 experiment * closed systems do not occur naturally

Systems’ thinking is derived from viewing elements and components that work together in relationships for the overall good of the vision or the whole. Every aspect of our lives is involved in a system whether it is electronics‚ biology‚ organizations‚ relationships‚ or ecology. By being able to recognize these systems we can focus on facts‚ not theories‚ and can look at a problem or issue understanding better where it came from‚ why it happened‚ and how to improve it. "Systems thinking is a discipline

"Systems thinking" involves thinking in loops rather than in straight lines. Because all parts of a system are interrelated‚ if change becomes initiated in one part of the system all parts will be impacted in a ripple effect all the way back to the original action – this is called a feedback loop. Discuss how a feedback loop would benefit a change initiative within an organization. Most systems have feedback loops‚ which enforce communication in some type of way. If an organization implements a

Suppose a | b ‚ so that b = at for some t ‚ and b | c‚ so that c = bs for some s. Then substituting the first equation into the second‚ we obtain c = (at)s = a(ts). This means that a | c‚ as desired. 6. Under the hypotheses‚ we have c = as and d = bt for some s and t . Multiplying
