CPU Cache Basics
After the processor accesses a location in memory, there's a high probability that the next location in memory that it will access is in the same area of memory. So to make the computer run faster, a a smaller, faster memory called a cache is placed between main memory and the processor. 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 ...
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 ...
Operating System Memory Management
Computers must keep several programs in memory, creating a need for memory management. Many different memory-management schemes are used. The operating system Keeps track of which parts of memory are currently being used, and moves data into out of memory, and allocates and deallocates memory as required. More ...
Electronic Circuits Basics
This article's main target is to teach the electronics language to readers that are not familiar with electronics by using a group of rules and simple equations that describe the behavior of every electronic component and the relationship between the components in the circuit. More ...
The Many Processes of Silicon Wafer Manufacturing
A silicon wafer is a thin, circular disc used in the manufacture of integrated circuits and semiconductors. The silicon wafer manufacturing process is interesting. More ...
Simplified Windows Architecture Overview
A simplified overview of the Windows operating system architecture divides it into user-mode and kernel-mode components. More ...
Microprocessor Registers
To a large extent the operation of a microprocessor involves loading, transferring, and manipulating the contents of registers. In this article you learn about the functions, and purposes of the register set of the Intel 8086 microprocessor. More ...
Pentium P5 Processor
The Pentium P5 processor was introduced in 1993 was the first superscalar processor. It featured two integer pipelines and a pipelined floating-point unit. This article describes other innovations introduced in the P5. More ...
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 ...
Digital to Analog Convertion with a Microcontroller
Digital to analog conversion (DAC) is the process by which a digital signal (expressed as a string of 1s and 0s) are converted to an analog signal (a continuously varying voltage). More ...
Difference between Stack, Heap, and Queue
Stack, heap, and queue are ways that elements are stored in memory. Stack elements are added to the top of the stack, and removed from the top of the stack. The mnemonic LIFO is used to describe a stack (Last-In-First-Out). With a queue, the first one in is the first one out. The mnemonic FIFO is used to describe a queue. A heap is an area of memory where elements can be stored and removed in any order. More ...
