The Celeron processor is a budget processor offering moderate performance at an affordable price. The Celeron processor is suitable for use in notebook and desktop computers running home-office applications and providing access to the Internet. More ...
Processor Affinity in Symmetric Multiprocessing
Processor Affinity refers to a process's tendency to continue running on the processor on which it is currently running. When a process executes on a CPU, that process's cache is populated with its most recently accessed data, if a process is moved to a different CPU, that second processor's cache must be populated with that data. More ...
Operating System Boot
The procedure of starting a computer by loading the kernel is known as booting the system. On most computer systems, a small piece of code known as the bootstrap program or bootstrap loader locates the kernel loads it into main memory, and starts its execution. More ...
Digital Logic Levels and Transfer Characteristics
A digital system uses discrete logic levels, 0 and 1, while the real world is a continuous range such as a voltage from 0 to 5. To make design easier, engineers view the system in the abstract. More ...
Introduction to the Raspberry Pi
The Raspberry Pi is a tiny bare-bones computer motherboard. You can easily make it into a Linux PC by connecting your own keyboard, mouse, and display. More ...
The AMD Athlon 64 Processor
AMD's Athlon 64 processor, released in September 2003, was their first 64-bit processor targeted for the workstation market to compete with Intel's Pentium 4. AMD's first 64-bit processor was the Opteron, released earlier in April that same year, targeted for the server market to compete with Intel's Xeon processor. More ...
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 ...
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 ...
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 ...
Operating System Processes
An Operating System Process is a program in execution. It includes the value in the program counter and in the processors registers. A process also includes a stack, data section, and a heap. 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 ...
Operating System Memory Paging Hardware Support
Paging is a memory management scheme that involves breaking physical memory into fixed-sized blocks and breaking logical memory into blocks of the same size called pages. When a process is to be executed, its pages are loaded into any available memory blocks. More ...
