First-Come, First-Served CPU Scheduling Algorithm
CPU Scheduling deals with the problem of deciding which of the processes in the ready queue is to be alocated the CPU. There are many different CPU scheduling algorithms. In this article we describe first-come, first-served scheduling. More ...
Multiuser Operating System Functions
Some operating system functions like resource allocation, accounting, protection and security exist not for helping the user, but rather for ensuring the efficient operation of the system itself. More ...
Arduino Microcontroller Development Platform
The benefit of the open source Arduino Microcontroller Development Platform is that the software is free and the hardware is cheap. This makes it one of the cheapest platforms on which to develop prototypes. More ...
Operating System Process Control Block
An Operating System Process is a program in execution. It includes the value in the program counter and in the processors registers. A process also includes a stack, data section, and a heap. Although two processes may be associated with the same program, they are considered two separate execution sequences. More ...
Operating System Memory Paging Hardware Support
Paging is a memory management scheme that involves breaking physical memory into fixed-sized blocks and breaking logical memory into blocks of the same size called pages. When a process is to be executed, its pages are loaded into any available memory blocks. More ...
The Use of SOI (Silicone on Insulator) Wafers in MEMS (Micro-Electro-Mechanical Systems) Production
The main advantage of Silicone on Insulator (SOI) technology is that they enable the manufacture of smaller devices. The manufacturing process optimizes the efficiency of transistors and allows chips to be packed close together, resulting in a greater yield per wafer. More ...
Operating System Memory Paging - Page Table Structure
One method of memory management is to break physical memory into fixed size blocks and break logical memory into same sized blocks called pages. The physical location of pages is tracked by a page table. More ...
Capacitors in AC Circuits
In an AC circuit capacitors exhibit a property similar to resistance called reactance and cause a phase shift between votage and current. The vector sum of resistance and reactance in an AC circuit is called impedance. More ...
Using the Microcontroller Timers
Timing is an essential function for generating signals with precisely determined duration, or for counting external events. For this reason, a timer subsystem is present in all microcontroller implementations. More ...
The Microcontroller Memory Map
a microcontroller is a set of resources. Each resource is identified by one or more addresses in an address space. The memory map is a graphic representation of how the resources are associated with addresses. More ...
Basic Computer Architecture
Computers today, even that PC on your desk are unbelievably complex. You can't understand computers without an understanding of the basics. In this article I explain basic computer architecture in simple, basic terms. More ...
Capacitors in DC Circuits
A capacitor is a component that can be used to store an electrical charge. A capacitor can be used to create a timer. This time delay can be used to smooth a changing current flow in a circuit, or it can be used to absorb spikes and prevent false triggering of other components. More ...
