Coaxial cable is a type of cable that has an inner conductor surrounded by an insulating layer, surrounded by a conductive shielding. Many also have an insulating outer jacket The diagram below illustrates the construction of a typical cable. Electrical signal flows through the center conductor. Show
Coaxial cable is a type of transmission line, used to carry high-frequency electrical signals with low losses. It is used in such applications as telephone trunklines, broadband internet networking cables, high-speed computer data busses, cable television signals, and connecting radio transmitters and receivers to their antennas. What kind of communications device sends and receives data and information to and from a digital line such as ISDN and cable?An ISDN modem sends digital data from a computer to an ISDN line and back. A DSL modem sends digital data from a computer to a DSL line and back. A cable modem, or broadband modem, is a digital modem that sends and receives digital data over the cable television network. Which network type connects each computer and device to a central device such as a hub or a switch?Star topology has become the dominant physical topology for LANs. The star was first popularized by ARCNET, and later adopted by Ethernet. Each node is connected directly to a central device such as a hub or a switch, as shown in Figure 5.17. Which statement best describes how the RFID standard works?Which statement best describes how the RFID standard works? The network uses radio signals to communicate with a tag placed in or attached to an object, animal, or person. What is the most important device for information communication?A computer is the most important device used in information communication, which is considered to have gone through five generations since it was created. It has application in several fields such as telecommunication, robotics, diagnostics etc.  RelatedWhat is data communication hardware?Data communications equipment (DCE) refers to computer hardware devices used to establish, maintain and terminate communication network sessions between a data source and its destination. DCE is connected to the data terminal equipment (DTE) and data transmission circuit (DTC) to convert transmission signals.Nov 26, 2018 RelatedWhich topology is best?A full mesh topology provides a connection from each node to every other node on the network. This provides a fully redundant network and is the most reliable of all networks. RelatedWhich network type connects each computer and device to a central device?Star network topology -- The most common network topology, star topology connects each device in the network to a central hub. Devices can only communicate with each other indirectly through the central hub. Hybrid network topology -- Any combination of two or more topologies is a hybrid topology. RelatedWhich of the following is the best definition for a LAN?LAN is defined as Local Area Network, a system that links together various pieces of electronic equipment from a small area. An example of a LAN is what a small business uses to connect their computers together. RelatedWhat is a sending device?What is a sending device? A device that initiates an instruction to transmit data, instructions, or information. RelatedWhich group developed the WiMAX standard?The standard for WiMAX technology is a standard for Wireless Metropolitan Area Networks (WMANs) that has been developed by working group number 16 of IEEE 802, specializing in point-to-multipoint broadband wireless access.
RelatedWhich of the following terms identifies any network based on the 802.11 family of standards?Which of the following is the greatest problem with regard to a bus network? ... Which of the following terms identifies any network based on the 802.11 family of standards? Wi-Fi. Which of the following kinds of modems is a modem that sends and receives digital data over and information to and from a digital line?
RelatedWhich of the following is a central communication device that allows computers and devices to transfer data wirelessly among themselves?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). RelatedWhat is the main technology used to connect computers to devices?Wi-Fi is the wireless technology used to connect computers, tablets, smartphones and other devices to the internet. Wi-Fi is the radio signal sent from a wireless router to a nearby device, which translates the signal into data you can see and use. RelatedWhich of the following technologies allows multiple computers to communicate over a network simultaneously?Network technologies allow two or more computers to connect with each other. The most common of these technologies include Local Area Network (LAN), Wireless Area Network (WAN), the Internet via client servers and Bluetooth. RelatedWhat is the difference between coaxial cable and electrical cable?What is the difference between coaxial cable and electrical cable?Whereas standard electrical cable consists of one or more wires through which an electrical current is passed (a flow of electrons), coaxial cable is used to pass radio frequency (RF) signals in the form of a transverse electromagnetic wave. RelatedWhat does the coaxial cable do on a cell phone?What does the coaxial cable do on a cell phone?The coaxial cable ties the three devices together. Using this technology, you can boost a weak cellular 3G & 4G signal. It cannot create signal where there was none, nor can it boost a landline wi-fi signal. RelatedWhat materials are used to make coaxial cables?What materials are used to make coaxial cables?Many conventional coaxial cable uses braided copper wire forming the shield. The insulating jacket are of varied materials. PVC to fire-resistant materials – different raw materials are used. RelatedWhat is hard line coaxial cable?What is hard line coaxial cable?Hard line coaxial cable makes use of a center conductor that is constructed out of materials such as copper, silver, aluminum, or steel and this type of cable is typically larger in diameter than other forms of coaxial cable. These types of cables may be used in high-strength signal transmission. What type of device is used to transmitting data instructions and information between a sending device and a receiving device?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.
What device is used to receive and transmit data?Modem. Modem is a device that enables a computer to send or receive data over telephone or cable lines. The data stored on the computer is digital whereas a telephone line or cable wire can transmit only analog data. The main function of the modem is to convert digital signal into analog and vice versa.
Which network type connects each computer and device to a central device such as a hub or switch?Star topology has become the dominant physical topology for LANs. The star was first popularized by ARCNET, and later adopted by Ethernet. Each node is connected directly to a central device such as a hub or a switch, as shown in Figure 5.17.
What type of device allows your computer or mobile device to communicate with other devices and the Internet wirelessly?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.
