plant, and the traffic lights in the city. Embedded operating systems are growing increasingly common in everyday appliances and other devices. These operating systems provide application interfaces for a wide range of different applications. The challenge for developers is to determine which operating system or programming language to use in a particular device or project, and how to utilize the parallelism and concurrency capabilities of the hardware and programming language chosen for a project

Input/output Devices I will be Using in the Next Three Years The input devices I will be using in the next few years will be my MacBook Air lap top and a Logitech wireless trackball mouse. The output devices I will be using are my wireless HP laser jet printer and my Bose mini laptop speakers. I know there are so many other input/output devices out there but for me this is simple and all I need to complete my daily tasks for work and school. Technology has made life a lot more simple and smaller

used in a 1921 play titled R.U.R.: Rossum’s Universal Robots, by Czechoslovakian writer Karel Capek. Robot is a Czech word meaning “worker.” Merriam-Webster defines robot as “a machine that looks like a human being and perform various complex acts; a device that automatically performs complicated, often repetitive tasks; a mechanism guided by automatic controls.” ISO describes a robot as “an automatically controlled reprogrammable, multipurpose manipulator programmable in three or more axes, which may

unipolar devices arise. FETs are voltage controlled devices that have a very high input impedance and low noise level. Task 1: Frequency response of FET amplifier Task 2: Frequency response of Common-Drain FET amplifier: In this task, we dealt with the frequency response of Common-Drain FET amplifier shown in Figure 1 below. A dc voltage of the value 15 V is applied to the drain while the Vgg is removed. In addition, a constant 200mVpp input voltage is

Framework The theoretical framework shows the diagram about the input-process-output (IPO) of the existing or present and the proposing system. A theoretical framework guides the proponents to the research to the outline possible courses of action or to present a preferred approach to an idea or thought. The diagram will be use on showing and explaining the flow and outcome of both systems. Input Input Process Process Output Output The teacher manually uses chalks to writes on board and students

Automation is the use of control systems and information technologies to reduce the need for human work in the production of goods and services. In the scope of industrialization, automation is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the muscular requirements of work, automation greatly decreases the need for human sensory and mental requirements as well. Automation plays an increasingly important role in the world economy and
