Priority 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 priority CPU scheduling. More ...
Electronic Circuits
There are five types of circuits; open, short, series, parallel, and series-parallel. Using Ohm's law, along with the reciprocal formula to calculate the equivalent resistance of resistors in parallel, you can calculate the voltage or current in any part of a circuit. More ...
Logical Versus Physical Memory Addresses
Computers use logical and physical addresses to access memory locatiuons. The CPU generates logical addresses. At run-time the Memory Management Unit (MMU) maps logical addresses to physical addresses. More ...
AMD Sempron Processor
The Sempron replaced the Duron as AMD's budget processor. The socket A Sempron is basically an Athlon XP with half the cache. The socket 754 Sempron is a cut down version of the Athlon 64 processor with half the cache. More ...
Computer Buses
A 16-bit bus can transfer 16 binary bits simultainiously. This requires 16 separate metal traces on a PC board. We also need traces for control signals. The whole group of traces is referred to as a bus. 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 ...
Processor Interrupts
An interrupt is a signal to the processor indicating an event has occurred that needs immediate attention. When an interrupt occurs, the processors normal path of execution is interrupted in order to run a routine to service the interrupt requester. More ...
Monolithic Kernel vs Microkernel vs Hybrid Kernel
An operating system consists of two parts, the kernel space which operates in privileged mode, and the user space which operates in unprivileged mode. More ...
Real-Time CPU Scheduling
In a real-time systems, is one whose operation depends on timing. A task must be serviced within a specific time interval. The tasks and their execution times must all be known. More ...
CPU Process Scheduling
CPU scheduling is the basis of multiprogrammed operating systems. By switching the CPU among processes, the operating system can make the computer more productive. 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 ...
Digital Logic Semiconductor Families
logic family refers to the way the semiconductors are designed to create gates. The first highly popular logic family, available in 1964, was TTL (Transistor-Transistor Logic). More ...
