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 ...
Using The I2C Bus
The I2C bus is used for communications between individual integrated circuits located on the same PCB. The I2C protocol supports multi-master, multi-slave communication, which means you can add a lot of functionality to your design. More ...
The Microcontroller's Asynchronous Serial Interface
An Asynchronous Serial Interface sends data one bit at a time, as apposed to a parallel interface which send one byte or one word at a time, and asynchronous means it sends them when its ready, without reference to a clock signal. More ...
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 ...
Priority 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 priority CPU scheduling. More ...
Operating System Process Scheduling Queues
The objective of multiprogramming is to have some process running at all times, to maximize CPU utilization. To meet these objectives, the process scheduler selects a process from a queue for execution on the CPU. More ...
CPU Process Scheduling
CPU scheduling is the basis of multiprogrammed operating systems. By switching the CPU among processes, the operating system can make the computer more productive. More ...
Operating System Services
An operating system provides an environment for the execution of programs. It provides certain services to programs and to the users of those programs. These operating system services are provided for the convenience of the programmer, to make the programming task easier. More ...
AMD's Phenom Processor
Since 2005 AMD has used the Athlon name for their processors. This changed in 2007 when they released their new processor called Phenom. So we must ask the question; what is the difference between the Athlon and the Phenom? More ...
The Motherboard Chipset
Because the chipset dictates the bus speed, type and amount of memory, and the type and number of I/O ports, much of a computer's performance is determined by its chipset. 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 ...
The Fetch, Decode, Execute Cycle
The Fetch, Decode, Execute cycle is paramount to the functioning of a microprocessor. In this article I'll describe the Fetch, Decode, Execute cycle simplified to its bare-bones in a highly simplified fictitious microprocessor. More ...
