Windows Operating System Services, Functions, Routines, Processes, Threads, and Jobs
The Windows operating system uses many confusing terms. This article explains the meaning of the terms: Services, Functions, Routines, Processes, Threads, and Jobs. More ...
The Android Operating System
Android os is similar to Apple ios in that it is a layered stack of software that provides a rich set of frameworks for developing mobile applications. At the bottom of this software stack is the Linux kernal. 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 ...
Multithreaded Programming Process' and Threads
A process generally has a complete, set of private resources, each process has its own memory space. Threads exist within a process, every process has at least one. Threads share the process's resources, including memory and open files. More ...
Stored Program Architecture
Almost every computer system ever made is based on the stored program architecture designed in 1945 design by the mathematician John Von Neumann. He described a system where data and instructions would be stored in memory. More ...
Multi-Processor Scheduling
Here, we discuss several concerns in multiprocessor scheduling in the context of Multicore, Multithreaded core, NUMA (Non-uniform memory access), and Heterogeneous multiprocessing architectures. 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 ...
Intoduction to Digital Electronics
The entire field of computer technology relies on transistors. This article describes how transistors are constructed and how modern MOSFETs are combined to make digital logic circuits. 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 ...
Introduction to Microprocessor Programming
Assembly language involves using instructions that are mnemonics called opcodes, along with values and/or addresses in hexadecimal notation. To make learning as easy as possible, we'll first learn how to program a simple microprocessor, the 6502. More ...
Direct Memory Access (DMA)
In early computers, all data transfers required the processor to read and write single words from memory until the entire transfer is complete. With DMA, the DMA controller takes control of the system buses to move data between the device and main memory. More ...
Intel's Dual-Core Core i3 Processor
Core i3 is an entry-level 2-core processor using the 32nm Westmere micro-architecture. With a Thermal Design Power (TDP) of 73 watts, the i3-530 is a cool-running chip that doesn't gobble loads of electricity, so those looking for a power-efficient, quiet machine will be happy with it. More ...
