The physical network consists of the cables (coaxial cable, twisted pair, fiber optic, and telephone lines) that connect the different hardware residing on the network, the adapter used on computers connected to the network (hosts), and any concentrators, repeaters, routers, or bridges used in the network.

How are computers linked together?
Using the Internet, computers connect and communicate with one another, primarily using the TCP/IP (Transmission Control Protocol / Internet Protocol).To connect to the Internet and other computers on a network, a computer must have a NIC (network interface card) installed.
What are the 3 ways computers can be linked together?
Each of these computer network types serves a different purpose and you may find a need to use each one.
- Local Area Network. A Local Area Network (LAN) connects two or more computers together via Ethernet cables.
- Wireless Area Network.
- Internet.
- Bluetooth.
What device connects physical networks?
Definition: A connectivity device to which network cables are attached to form a network segment. Hubs typically do not filter data, but instead retransmit incoming data packets or frames to all parts. Almost all networks today use a central hub or switch to which the computers on the network connect.
What are two types of physical connections?
Wired connection: wired connection means connection through a physical cable (back bone). There are two types of connections in physical structure. Multipoint. Bus Topology: In bus topology using a single cable to connect all devices.
What is two or more computers connected together?
When two or more computers are connected together so they can communicate with one another, they form a network. The largest computer network in the world in the Internet.
What is a group of computers linked together called?
The correct answer is Network. A network is a group of computers and devices are connected together through various means. The largest network in the world is the Internet.
How do I connect 4 computers together?
In order to physically connect three or more computers, you should use crossover Ethernet cable. You must be able to plug the Ethernet cables into a device that will allow signals to be transmitted to one another. There are several devices that will allow you to do this: a hub, a switch, or a router.
How do two computers communicate on a different network?
The Ethernet standard is what allows these machines to talk to one another. Each computer (or printer or other device) that is connected to this Ethernet cable is set up to have a unique address, or IP Address.
What are physical connections?
Physical connection means the number of trunk lines or complete circuits and connections, including connections by wire, optics, radio signal or other means, required to furnish reasonably adequate telecommunications service between telecommunica- tions providers.
What is physical network?
A physical network is the sum of the physical hardware parts that make up a network, including cables and routers – this is unrelated to the virtual logical network that users see when they log into their computers and check the networks tab.
What is physical connectivity?
Physical connectivity encompasses transport, information communications technology (ICT) and energy infrastructure as well as the regulatory framework and the software necessary to deliver associated services and utilities.
What is physical computer structure?
The physical structure of a computer is called hardware. Examples of computer hardware are Motherboard, RAM, CPU, Mouse, Keyboard, CD, DVD, hard disk etc.
What are the major types of physical connections?
There are three types of physical cables used in a wired network.
- Twisted Pair. It consists of a pair of copper wires twisted around each other; the wires are around 1 to 2 mm thick and they are twisted to reduce the interference from the surrounding wires.
- Coaxial Cable.
- Fiber Optic.
Which is the physical network of computers all over the world?
The Internet is the world’s largest computer network.
When computers are connected in LAN then?
Computers connected to a LAN can share information and/or share peripheral equipment.
Is a computer connected to two network?
Solution(By Examveda Team)
A bridge joins two similar types of networks so that they look like one network. The word transparent is often used with bridges because network clients do not know the bridge is even in place. A gateway joins two dissimilar networks.
What is the key term for devices that are connected together?
What is a network? A network is two or more computers (or other electronic devices) that are connected together, usually by cables or Wi-Fi.
How do I connect 100 computers together?
You need a router, some switches, and some cables.
- install router to line from isp.
- set up switches in convenient locations to reach your PCs.
- run cables from router to the switches.
- run cables from switches to PCs.
How many computers can be connected to a switch?
In addition, two power outlets are required. Alternatively, if there is a single 48-port switch, 47 devices can be supported, with only one port used to connect the switch to the rest of the network, and only one power outlet needed to accommodate the single switch.
Can supercomputers run Windows?
Over 94.2% of supercomputers are Linux based. So far, only two supercomputers are found to have Windows OS. Even more surprising may be that the faster of the two systems is a China-based system at #94, which runs Windows HPC Server 2008 R2.
