are no special application requirements, it is advisable to select the device in these two companies.Hardware Resources for 5.1.2 devicesHardware resources are important criteria for device selection. Hardware resources include logical resources, I/O resources, cabling resources, DSP resources, memory resources, phase-locked loop resources, serial transceiver resources, and hard-core microprocessor resources.The need for logical resources and I/O res

number of tasks of Integrated Wiring. However, twisted pair wires have weak anti-aging capabilities, and only one image can be transmitted at a time. Therefore, it is suitable for video surveillance of network cameras in medium and short distances, with relatively scattered camera points, or with relatively close but concentrated points, such as banks, hotel chains, supermarkets, or university campuses. Optical fiber.Optical Fiber Transmission has the following advantages: long transmission dis

parabolic surface, so that the antenna is located in the parabolic surface of the internal reflection focus, through the electromagnetic waves reflected in the focus of the formation of energy concentration, thereby enhancing the electromagnetic signal transceiver, To achieve enhanced signal in a specific direction. The key to making a simple gain antenna is to find a more regular metal parabolic surface and compute the focus position of the parabo

direction, and if any network segment are severed, all network transmission ceases. A host on a bus network is called a station or workstation. In a bus network, every station receives all network traffic (traffic), and the traffic generated by each station have equal Tran Smission priority. Each network segment is, therefore, a collision domain. In order for nodes to transmit on the same cable simultaneously (simultaneous), they use a media access control technology such as car

multicast distribution service, is a broadband point-to-point access system that can access voice, data and video services. LMDS system using millimeter wave transmission, working in the 20-40ghz band, can provide up to 155.52Mbps user access rate, known as a "Wireless optical fiber" access system. In addition, the LMDS system supports all major voice and data transmission standards, such as ATM, TCP/IP, and MPEG-2.The *LMDS system adopts a kind of honeycomb structure configuration, by which on

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

The following describes several commonly used optical fiber connectors in network engineering: ① FC Type Optical Fiber Jumper: the external reinforcement mode is a metal sleeve, and the fastening mode is a screw buckle. Generally used on the ODF side (most used on the distribution frame) ② SC-type optical Jumper: the connector connecting the GBIC optical module. Its housing is rectangular, And the fastening mode is plug-and-

Sales and dispatch personnel (Procurement Center) responsibilities related to functions: Z11 linkage (need for goods movement and Delivery order creation rights), manual delivery, linkage information query. In order to avoid redundancy, the query and execution create roles individually when creating a role, which avoids querying for things code in each execution role, taking into account that only the query permission is not execu

UART (Universal asynchronous transmitter ER/transmitter)General asynchronous transceiver UART is a chip used to control computers and serial devices. One thing to note is that it provides an interface to the RS-232C data terminal device so that the computer can communicate with the modem or other serial devices that use the RS-232C interface. As part of the interface, UART also provides the following functions: Converts parallel data transmitted fr
