In This Video We Are Going to See How a Personal Computer Hardware Is Organised the PC Was Designed with an Open Architecture
In this video we are going to see how a personal computer hardware is organised The PC was designed with an open architecture. This means that it uses standard modular components. We can add, replace, update or swap them easily and the computer will identify and handle the new devices automatically. The main component of a computer system is the motherboard or main board. It is a printed circuit board (PCB) that holds the main components of the computer and the electronics needed to communicate between them and to expand the system. We could say that it is the central nervous system of the computer. A motherboard provides the electrical connections by which the other components of the system communicate. Unlike a backplane, it also contains the central processing unit and hosts other subsystems and devices The form factor is the specification of a motherboard – the dimensions, power supply type, location of mounting holes, number of ports on the back panel, etc. In the IBM PC compatible industry, standard form factors ensure that parts are interchangeable across competing vendors and generations of technology, while in enterprise computing, form factors ensure that server modules fit into existing rack mount systems. Traditionally, the most significant specification is for that of the motherboard, which generally dictates the overall size of the case. The most used form factor for IBM PC compatible motherboards is ATX (Advanced Technology Extended) and its derivatives. For small form factor mainboards mini ITX is the de facto standard. A power supply unit (PSU) converts mains AC to low- voltage regulated DC power for the internal components of a computer. -

Investigating Choices of Appropriate Devices for One-To-One Computing Initiatives in Schools Worldwide
International Journal of Information and Education Technology, Vol. 6, No. 10, October 2016 Investigating Choices of Appropriate Devices for One-to-One Computing Initiatives in Schools Worldwide M. Sirajul Islam and Annika Andersson schools should be governed by “creating an environment in Abstract—The use of technology in schools is rapidly which the child will become highly involved in experience of increasing – today most notably through the one-to-one (1:1) a kind to provide rich soil for the growth in intuitions and programs that are being implemented all around the world. concepts for dealing with thinking, learning, playing, and so Considering how new technologies are emerging fast and obsoleting others in schools, there is a need to continuously on” [5]. In this direction, one of the first practical initiatives monitor and understand the features of various devices in terms on implementing constructionist learning for children with of embedded technology and interaction with users. This paper computers was the development of programming language therefore presents the nature of computing devices used in 1:1 called „Logo‟ in 1967. Following such initiatives, Alan C. computing programs in schools around the world, including Kay, who was closely associated with Papert for promoting investigating the benefits and drawbacks, by means of a and implementing computer based educational constructivism, systematic literature review and a survey conducted in some schools in Sweden. The paper also presents findings based on developed a laptop computer for children in 1970 based on how the various uses of technology affect cooperation practices the sketches of the KiddiComp called „Daynabook‟ as well as personal exploration. -
