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 ...
Shortest-Job-First 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 shortest-job-first scheduling. 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 ...
Operating System Memory Page Sharing
In a paged environment sharing of memory among processes provides numerous benefits including sharing non-self-modifying reentrant code and interprocess communication. More ...
Program Flow Charting
Depending upon the language used, program code my be difficult for humans to read and understand. However, one type of programming that is very easy to understand is flow charting. More ...
Microcontroller Internal EEPROM (Electrically Erasable Programmable Read Only Memory) Memory
In some situations it is required that some program parameters such as configuration settings be keept after the system is powered off. This is made possible by including a EEPROM internally to the microcontroller. 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 ...
Getting started with Raspberry Pi
So you have a Raspberry Pi, or you're thinking of getting one, and you want to know how to get started and how to become a master user of one. 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 ...
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 ...
Operating System Process Management
A program is not a process. A program is a file containing a list of instructions stored on disk. A process is an active entity with a program counter specifying the next instruction to execute and a set of resources. A program becomes a process when an executable file is loaded into memory. More ...
Intel's Core 2 Processors
Intel's Core 2 processors, released in July of 2006, are based on the Core microarchitecture, a dual core design using a 65nm manufacturing process to put 291 million transistors on a 143 square mm die. Each core has its own 64KB L1 cache. The two cores share an L2 cache that can be either 2MB or 4MB. More ...
