BLOCK DIAGRAM OF MICROCOMPUTER
What is microcomputer? Definition - Computer Notes
Notebook Notebook is the smallest microcomputer, which can be ultra-mobile 3 inches thick with less than 3 pounds lightweight and smaller than a briefcase, allow for easy setup in a room. A notebook can be effectively connected to the Internet ISP via a cable or Wi-Fi. Laptop Laptop microcomputer is bigger than the notebook computer powered by a battery and designed for
Power Supply Classification And Its Various Types - ElProCus
The power supply block diagram, and the step by step conversion of 230V AC to 12V DC is discussed below. Generally, these types of power supplies use an essential microcomputer for controlling as well as monitoring the operation of a power supply. A power supply provided with an interface of computer uses standard (or) proprietary[PDF]

Direct memory access (DMA) - Computer Notes
For example, a sound card may need to access data stored in the computer’s RAM, but since it can process the data itself, it may use DMA to bypass the CPUo cards that support DMA can also access the system memory and process graphics without needing the CPU. Ultra DMA hard drives use DMA to transfer data faster than previous hard drives that required the data to first [PDF]
