Which of the following is a central communications device that allows computers and devices to transfer data wirelessly among themselves or to Transfe?

Wireless access point is a central communication device which allows devices and computers to transfer data wirelessly or to a wired network which are using technologies such as Wi-Fi.

What are the devices that let you communicate with the computer?

Below is a full listing of all the different types of communications devices you may encounter when dealing with a computer.

• Bluetooth devices.
• Infrared devices.
• Modem (over phone line)
• Network card (using Ethernet)
• Smartphone.
• Wi-Fi devices (using a Wi-Fi router); examples shown below.

Which device is used for data transmission over Internet?

A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to recreate the original digital information.

Which device is used to send messages data or information to other devices?

modem, (from “modulator/demodulator”), any of a class of electronic devices that convert digital data signals into modulated analog signals suitable for transmission over analog telecommunications circuits.

Which of the following is a device that provides a central point for cables in a network?

An ethernet switch is a device that provides a central connection point for cables from workstations, servers, and peripherals.

What is the central device in a wired network that receives signals from the sending device and forwards the signals on to the receiving device?

Device that provides a central point for cables in a network. Larger networks typically use a hub, while smaller networks use a switch. Some hubs/switches include routers. Hub/Switch receives data from many directions and then forwards it to one or more destinations.

Which device allows you to enter data and instructions into a computer?

A keyboard is an input device that contains key’s users to enter Data and instructions into a computer.

What are communication devices used for?

Communication devices, also called Augmentative and Alternative Communication (AAC) devices, are equipment people use to communicate without using verbal speech.

What is transmission in data communication?

Data transmission is the transfer of data from one digital device to another. This transfer occurs via point-to-point data streams or channels. These channels may previously have been in the form of copper wires but are now much more likely to be part of a wireless network.

What is data transmission in computer network?

Data transmission refers to the process of transferring data between two or more digital devices. Data is transmitted from one device to another in analog or digital format. Basically, data transmission enables devices or components within devices to speak to each other.

What is the computer communication?

1. The process by which people create, exchange, and perceive information using networked communication classifications. It also includes nonnetworked computers that facilitate encoding, transmitting, and decoding information.

What is computer communication system?

A computer communication network is an interconnection of a collection of several computers from which the user can select the service required and communicate with any computer as a local user.

What is a wireless access point used for?

A wireless access point is a central communications device that allows com- puters and devices to transfer data wirelessly among themselves or to transfer data wire- lessly to a wired network (Figure 8-7 on page 303). Wireless access points have high-quality antennas for optimal signals.

What is a communication device in networking?

A communications device is any type of hardware capable of transmitting data, instructions, and information between a sending device and a receiving device. One type of communications device that connects a communications channel to a sending or receiving device such as a com- puter is a modem.

Which device converts analog signals to digital signals?

If a communications channel uses analog signals (such as some telephone lines), however, the modem first converts between analog and digital signals. The following pages describe the following types of communications devices: dial-up modems, ISDN and DSL modems, cable modems, wireless modems, network cards, wireless access points, and routers.

What is the difference between an access point and a router?

Wireless access points have high-quality antennas for optimal signals. A router is a communications device that connects multiple computers or other routers together and transmits data to its correct desti- nation on the network. A router can be used on any size of network.
