Factors in Choosing an Oscilloscope
An oscilloscope is an instrument used to display the waveform of electronic signals. It draws a graph of the voltage as a function of time. A digital oscilloscope can also store waveforms and perform mathematical analysis of the waveform. More ...
Introduction to Computer System Main Memory Operation
The CPU can be shared by a set of processes. Using CPU scheduling, we can improve the utilization of the CPU and the speed of the computer's response. To realize this increase in performance, multiple processes must be kept in memory. 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 ...
CPU Chip Packaging
Over the development time of the computer, several different designs of packaging for the CPU chip die have been used. Each type of packaging has its advantages and disadvantages. This article reviews some common packages that might still be in use. More ...
Operating System File Management
The operating system abstracts from the physical properties of its storage devices to define a logical storage unit, the file. The operating system maps files onto physical media and accesses these files via the storage devices. More ...
AMD's Microarchitectures
A microarchitecture describes the physical features, functions, and the technology level of the processes used to manufacture the core of a microprocessor. This article describes the microarchitectures used by AMD. More ...
Virtual Memory and Memory Paging
In the early days of computers, memory chips were small capacity, scarce, and expensive. Because of this a memory management scheme called paging was invented. More ...
Operating System Memory Allocation Methods
Operating System Memory Allocation is the process of assigning blocks of main memory to various running processes and to move processes back and forward between the main memory and disk. 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'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 ...
Microcontroller's Parallel I/O System
The most common way for microcontrollers to interact with the outside world is the The digital I/O lines. More ...
