What is meant by wired logic?

A wired logic connection is a logic gate that implements boolean algebra (logic) using only passive components such as diodes and resistors. A wired logic connection can create an AND or an OR gate. The limitations are the inability to create a NOT gate and the lack of level restoration.

Why can is wired and logic?

CAN protocol is based on Wired AND logic. Wired AND logic means – 0 is dominant. Meaning of Zero dominant is that whenever there is a conflict in two data transmissions, then the sender who is sending 0 will get the priority.

What is a wired and line?

Glossary Term: Wired-And When multiple high-impedance (open-collector or open-drain) output pins are connected to a signal line (e.g. a bus) and the system is designed so no more than one is on, a wired-and signal is achieved. This achieves the equivalent of a logical AND function.

What is wired or connection?

A wired network connection is described as a configuration that involves cables which establish a connection to the Internet and other devices on the network. Data is transferred from one device to another or over the Internet using Ethernet cables.

What is wired and bus?

This applet demonstrates a Wired-AND bus, another common circuit that allows connecting multiple gates to one bus signal. The idea is to use so-called open-collector transistors as the sole connection to the bus. While the output transistor is conducting, the voltage on the bus is actively driven to a low value.

What is meant by Tri State logic?

In digital electronics three-state, tri-state, or 3-state logic allows an output or input pin/pad to assume a high impedance state, effectively removing the output from the circuit, in addition to the 0 and 1 logic levels.

What is the difference between wired and wireless communication?

A wired network employs wires to link devices to the Internet or another network, such as laptops or desktop PCs. (b) Wireless Network: “Wireless” means without wire, media that is made up of electromagnetic waves (EM Waves) or infrared waves. Antennas or sensors will be present on all wireless devices.

What are the different types of wired medium used for communication?

There are four main types of wired media in use:

  • Twisted pair. Shielded, copper-based, twisted-pair cable.
  • Coaxial. Copper-based coaxial cable.
  • Ethernet. Unshielded, copper-based, twisted-pair cable.
  • Fiber optic. Glass or plastic-based fiber-optic cable.

What is Z state?

High impedance or High-Z or Hi-Z is a state when the output is not driven by the input(s), that means output is neither high (1) nor low (0). The output is electrically disconnected from the circuit. It is used in buses, when you want to transfer more than one signal through same wire without the loss of data.

What are the three states of tri-state logic?

Tristate buffers have three states; 1/On, 0/Off and Disconnected / Floating. A chip-enable pin is used to activate the device.

What are the types of wired communications?

What is wired communication media?

Wired communication refers to the transmission of data over a wire-based communication technology. Wired communication is also known as wireline communication. Examples include telephone networks, cable television or internet access, and fiber-optic communication.
