real time operating system

We generally use the "date-s" command to modify the system time. For example, set the system time to the August 19, 2007 command as follows. #date-S 08/19/2007 The command to set the system time to 11:20 P.M. 0 seconds is as fol

Structured wiring is now widely used in communications, finance, real estate, education, shipping and hotels and other industries. With the continuous expansion of wiring infrastructure, the management is becoming more and more complicated. The most difficult problem for the network administrator is to update the document record. Traditionally, wiring documents have been manually updated, and it is not surprising that I have been negligent, and have g

Operating System-solutions for mutual exclusion between processes-ensure that only one process enters the critical section at a time (2)-Peterson solution, system-peterson This article continues with the previous article about how to allow only one process to enter the critical section at a

First, the introduction Today, most of the voice, data and image transmission in office buildings, buildings, university campuses, government departments and even residential communities in intelligent buildings are based on structured cabling systems on their physical structure. We know that in the Iso/osi protocol, the physical layer is the basis of the network system, all network communications rely on the physical layer of the cable to the voice,

Abstract:The study of real-time video network transmission technology is of great significance for video applications. In this paper, an implementation diagram of a real-time video network transmission system is provided. Combined with the principle diagram, the key technolo

monitoring | design Summary: This paper presents a real-time monitoring system based on OS kernel service and multithread technology, which solves the problem that the previous monitoring system can not recover the abnormal webpage in time. The Transmission control part and
