Is a communications device that enables a computer or device that does not have networking capability to access a network?

COMMUNICATION DEVICES A communications device is any type of hardware capable of transmitting data, instructions, and information between a sending device and a receiving device. At the sending end, a communications device sends the data, instructions, or information from the sending device to a communications channel. At the receiving end, a communications device receives the signals from the communications channel. Some types of communications devices: dial-up modems, digital modems, wireless modems, network cards, wireless access points, routers, hubs and switches, repeaters, bridges and gateways. Dial-up modems: A dial-up modem usually is in the form of an adapter Digital modems: A digital modem is a communications device that sends and receives data and information to and from a digital built-in Wi-Fi connectivity. Wireless modems: A wireless modem is a modem that bypasses the telephone system and connects directly to a wireless network, through which it can directly access the Internet
connectivity provided by an Internet Service Provider (ISP) e.g. FLOW or Digicel. Wireless modems may be prebuilt into smartphones, mobile phones and personal data assistants (PDAs).
Network cards- A network card, sometimes called a network interface card (NIC pronounced nick), is a
communications device that enables a computer or device Wireless access points- Wireless access points (WAPs) are networking devices that allow Wi-Fi devices to connect to a wired network. They form Wireless Local Routers: A router is hardware device designed to receive, analyze and move incoming packets of data to another network. A router is a communications dev connects multiple computers or other routers together and transmits data to its correct destination on a network. Hubs and switches- A hub or switch is a device that provides a central point Repeaters- A repeater is a network device that retransmits a received signal with more power and to an extended geographical network boundary than what would be capable with the original signal. A repeater is implemented in computer networks to expand the coverage area of the network, spread a weak or broken signal and/or service remote nodes. Repeaters amplify the received/input signal to a higher frequency domain so that it is reusable, scalable and available. Bridges- A bridge is a type of computer network device that provides interconnection with other bridge networks that use the same protocol. Bridge devices are used to connect two different networks together and provide communication between them Gateways- A gateway is a data communication device that provides a remote network with connectivity to a host network. Gateways serve as the entry and exit point of a network; all data routed inward or outward must first pass through and communicate with the gateway in order to use routing paths. ROUTER VS MODEM: In short, your router creates a network between the computers in your home or office, while your modem connects the network-and thus the computers on it – to the internet. ROUTER VS WIRELESS ACCESS POINT: A WAP is a device that allows clients to connect wirelessly while a router is a network device that directs the traffic from one network element to another. WHY DO COMPUTERS NEED COMMUNICATION DEVICES? A computer can work fine without a communication device. However, for a computer to communicate with other computers they need a communication device. For example, for your computer to connect to the Internet to view a web page it needs a communication device. Without a communication device you’d have to use a sneaker net to transfer or share data between computers. Sneaker net is an informal term for the transfer of electronic information by physically moving media such as magnetic tape, floppy disks, optical discs, USB flash drives or external hard drives between computers, rather than transmitting it over a computer network. Questions
Next Topic: Objective 2: Describe correctly at least three communication software that are used in computer networks- Communication software should include applications for IRC, email, Internet telephony, pod-casting, blogging, and file transfer. Reference
What enables a computer or device that does not have built in networking capability to access a network?Communications and Networks. What is the communication device that allows the computer to access a network?A router is a hardware device that allows you to connect several computers and other devices to a single Internet connection, which is known as a home network. Many routers are wireless, which allows you to create a home wireless network, commonly known as a Wi-Fi network.
What is a communication device called?Communication devices, also called Augmentative and Alternative Communication (AAC) devices, are equipment people use to communicate without using verbal speech.
Which device is used to connect network devices so they can communicate with one another?Hubs connect multiple computer networking devices together. A hub also acts as a repeater in that it amplifies signals that deteriorate after traveling long distances over connecting cables. A hub is the simplest in the family of network connecting devices because it connects LAN components with identical protocols.
