. Composition of the file event handlerShows the four components of the file event handler, which are sockets, I/O multiplexing programs, file event dispatcher (dispatcher), and event handlers, respectively.A file event is an abstraction of a socket operation that produces a file event whenever a socket is ready to perform operations such as a connection answer (accept), write, read, close, and so on. Because a server typically connects multiple sockets, multiple file events can occur concurrent

Comprehensive analysis of the differences between optical fiber cables, network cables and cables In network hardware, another kind of media that can't be ignored is the network transmission media, which is usually called a network cable. Currently, common cables include thin twisted pair wires, optical fiber cables, coaxial cables, and coarse coaxial cables. 1. optical fiber cables:Fiber Optic Cable is a

Video Monitoring has six transmission modes: Video baseband transmission, optical fiber transmission, network transmission, microwave transmission, twisted pair balanced transmission, and broadband co-cable transmission. 1. Video baseband transmission: Is the most traditional television monitoring Transmission Mode, 0 ~ 6 MHz video baseband signals are directly transmitted through coaxial cables (non-balanced) without any processing. Its advantages ar

, the operating system provides IO multiplexers (for example, select, poll, and Epoll under Linux), which are encapsulated by Java (typically using the best performing epoll) and the corresponding IO multiplexing API. The typical programming pattern for the Multiplexed API for NIO is as follows:Selector Selector = Selector.open ();//creating a multiplexerSocketchannel channel = Getchannel ();//get Socketchannel in NiO, representing an IO connection//register the channel with the

transmission rate (Mbps) of the cable. The Mbps is measured by the number of binary bits transmitted by the line per unit of time,MHz is the number of electrical signals on the line per unit time.Twisted Pair wires can be used in CMSA/CD-based (Carrier Sense Multiple Access/Collission Detection,Carrier-induced Multi-Channel Access/conflict detection) technology, that is, 10 BASE-T (10 Mbps) and 100 BASE-T (Mbps) Ethernet (Ethernet), specific provisions include:● The maximum length of a twisted

version of Libevent (likevent).Ix. Choosing the best I/O multiplexing1. Encapsulating I/O multiplexing as an event multiplexerAs we said earlier, the Libevet itself is a typical reactor pattern, and a component in reactor mode is called the event multiplexer, which is actually the encapsulation of an I/O multiplexing. So the problem is that the I/O multiplexing mechanism provided under each system is not the same, even if there are many interfaces

In a two-way cable TV system, to make reverse transmission work normally, the confluence noise must be reduced. Most of the confluence noise is formed by a space electromagnetic interference string into the reverse system. In a Bidirectional CATV system, cables are one of the most vulnerable components to interference. In order to make the reverse system work normally, four Shielded Cables with High attenuation Shielding must be used. This paper introduces two methods for measuring the four shie

Common LAN TopologiesThe structure of star structure is one of the most widely used in local area network, which is used almost all in enterprise networks. Star Network is almost Ethernet (Ethernet) network dedicated, it is because the network of workstations node devices through a network of centralized devices (such as hubs or switches) connected together, each node is a star-shaped distribution named. This type of network currently uses the most transmission medium is twisted-pair, such as th

+ C-DOCSIS: national standard technology, for China Radio and Television Network, compatible with the original CMTS system. • FTTH: it is still pilot and the CATV access method is unclear. In the FTTH solution, CATV access is divided into three types: Single-fiber three-wave, dual-Fiber Three-wave, and fiber-optic Coaxial Dual-household. Because a single-fiber three-wave adds one WDM module per household, the network construction cost is high, single

like a pipe, it's a channel. The channel is different from the flow where the channel is bidirectional and can be used for reading, writing, and simultaneous read and write operations.The underlying operating system's channels are generally full-duplex, so Full-duplex channel can better map the underlying operating system APIs than streaming.Channel mainly divided into two major categories: Selectablechannel: User Network Read-write FileChannel: for file operations The Serversocketchannel and s
