Which of the physical connections is the fastest?
Fiber is the fastest way to access the Internet, but it’s also the most expensive. Fiber converts electrical signals to light which travels through tiny glass filaments.
What are the most dramatic changes in connectivity and communications in the past few years has been?
One of the most dramatic changes in connectivity and communications in the past few years has been. Widespread use of mobile devices with wireless internet connectivity. In a communication system, which among the following originate and accept messages in the form of data, information, and/or instructions?
What are countrywide and worldwide networks?
WAN (wide area network) Countrywide and worldwide networks that use microwave relays and satellites to reach users over long distances.
What network system uses central servers to coordinate and supply services to other nodes on the network?
Remote users can connect to an organization’s network through this type of secure private connection. … This device enables connectivity between two LANS or a LAN and a larger network. Network gateway. This type of network strategy uses central servers to coordinate and supply services to other nodes on the network.
What is a network where the nodes are in close physical proximity to each other?
Response: A network of devices in close physical proximity is called a local area network (LAN).
What uses standard telephone lines to provide high speed connections?
Digital subscriber lines (DSLs) are high-speed Internet connections that use standard telephone lines. DSL uses the standard twisted-pair telephone lines that come into every home for normal telephone service. These lines, because they were developed only for voice signals, are restricted in bandwidth and data rate.
Is a device that allows one LAN to be linked to other LANs or to larger networks?
Routers: Network routers allow you to connect to other LANs (if need be), and they assign IP addresses to your devices. A wireless router will allow computers with Wi-Fi NICs to connect with each other and with the internet.
Does telephone lines use coaxial cables?
Standard telephone lines use coaxial cables and with good reason. First, they support greater cable length, which makes them perfect for long-distance wiring. Also, they offer better shielding from any cross talk and have transmission speeds of up to 10Mbps.
Are invisible images or HTML code hidden?
Web bugs are usually hidden within the HTML code for a web page or in an e-mail message as an invisible image.
Are continuous electronic waves?
A continuous wave or continuous waveform (CW) is an electromagnetic wave of constant amplitude and frequency, typically a sine wave, that for mathematical analysis is considered to be of infinite duration.
What bandwidth is used in special leased lines?
Leased lines offer fixed bandwidth connections between two sites. What bandwidths can you choose? 2Mbit/s to 10Gbit/s, typically. These are delivered using fibre-optic cable.
Are electronic systems that transmit data from one location to another?
Electronic systems that transmit data from one location to another. Whether wired or wireless, every communication system has four basic elements.
What is the name of any device connected to the network?
node. Any device connected to a network, such as a personal computer, tablet PC, mainframe, server, network equipment, or printer. Also called a station.
Is a physical media made up of a pair of cables twisted with each other?
Twisted pair is a physical media made up of a pair of cables twisted with each other. A twisted pair cable is cheap as compared to other transmission media. Installation of the twisted pair cable is easy, and it is a lightweight cable. The frequency range for twisted pair cable is from 0 to 3.5KHz.
What type of signal is broadcast as a continuous wave?
Analog signals are measurements of continuous waveforms that vary with time. Analog signals vary in frequency and amplitude just as the waves carrying the information continuously vary. Analog signals use a medium to transmit information.
Is the actual speed of data transfer?
|throughput||The actual speed of data transfer that is achieved. It is usually less than the data transfer rate and is measured in megabits per second (Mbps).|
|transmission media||The radio waves or cable that transport data on a network.|
Which is the most popular wireless networking technology?
Thus far, 802.11 has become the most popular wireless data networking technology.
What is the full form of modem?
Modem is short for “Modulator-Demodulator.” It is a hardware component that allows a computer or another device, such as a router or switch, to connect to the Internet. … Dial-up modems also required full use of the local telephone line, meaning voice calls would interrupt the Internet connection.
Is speed the same as bandwidth?
Though interrelated, they are two very different things. While network speed measures the transfer rate of data from a source system to a destination system, network bandwidth is the amount of data that can be transferred per second (“the size of the pipe”).
Which transmission media is able to transmit data the fastest?
Fiber optic cables have greater transmission speed, high bandwidth, and the signal can travel longer distances when compared to coaxial and twisted pair cables.
Which transmission medium transmits data fastest?
A wired connection that utilizes optical fibers is the quickest transmission medium for data transfer. The traits like low maintenance costs, ability to assist the long distance communication, speedy transfer, and efficiency, make the optical fibers, fastest transmission medium.
