Quick Answer: What Is The Central Device Is Star Topology?

Where is star topology used?

Star Network Topology Star network topologies are common in home networks, where the central connection point may be a router, switch, or network hub.

Unshielded Twisted Pair (UTP) Ethernet cabling is typically used to connect devices to the hub, though coaxial cable or optical fiber may also be employed..

Which topology is fastest?

star topologyAnswer. Data can be transferred at fastest speed in star topology .

Why star topology is best?

5.0 CONCLUSION. A Star Network Topology is best suited for smaller networks and works efficiently when there is limited number of nodes. One has to ensure that the hub or the central node is always working and extra security features should be added to the hub because it s the heart of the network.

Which topology is used in Ethernet?

Ethernet is the most widely used network topology. You can choose between bus and star topologies, as well as coax, twisted-pair, or fibre optic cabling. And with the right connective equipment, multiple Ethernet-based LANs can be linked together.

What is the central device in star topology Mcq?

Answer: According to the question the central device in star topology is hub. In star topology every node on network is connected through a central device which is hub or switch or router.

What is central device?

Device Central provides a centralized way for an organization to connect and monitor supported Bluetooth peripherals. Using the simple user interface, Device Central easily pairs and unpairs Bluetooth peripherals, monitors connection status, and provides details on supported peripherals.

Which of these is not a guided media?

Which of this is not a guided media? Explanation: Wireless LAN is unguided media. Explanation: Unshielded twisted pair(UTP) is commonly used in home access.

Which of the following is a type of guided media?

Guided media, which are those that provide a conduit from one device to another, include twisted-pair cable, coaxial cable, and fiber-optic cable. Guided Transmission Media uses a “cabling” system that guides the data signals along a specific path.

Which of the following is used as a primary storage device?

Random Access Memory (RAM) and cache are both examples of a primary storage device. The image shows three different types of storage for computer data. Primary storage’s key differences from the others are that it is directly accessible by the CPU, it is volatile, and it is non-removable.

Which primarily uses guided media?

Online Test26.Which of the following primarily uses guided media?a.cellular telephone systemb.local telephone systemc.satellite communicationsd.radio broadcasting

What is topology with example?

A topological space is a set endowed with a structure, called a topology, which allows defining continuous deformation of subspaces, and, more generally, all kinds of continuity. Euclidean spaces, and, more generally, metric spaces are examples of a topological space, as any distance or metric defines a topology.

What are the 5 network topologies?

There are five types of topology – Mesh, Star, Bus, Ring and Hybrid.

How Internet is an example of network?

A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data. An example of a network is the Internet, which connects millions of people all over the world. Network topologies and types of networks. …

Which topology is used in Internet?

The Internet is a mesh network. The tree network topology, also called a star of stars, is a network where star topologies are themselves connected in a star configuration.

What is a star topology?

A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down.

How is star topology connected?

In star topology, each computer is connected to a central hub using a point-to-point connection. The central hub can be a computer server that manages the network, or it can be a much simpler device that only makes the connections between computers over the network possible.

What is meant by data communication?

Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data. … The best-known computer network is the Internet.

What are the characteristics of star topology?

Characteristics of a star topology are as follows: All cables run to a central connection point. If one cable breaks or fails, only the computer that is connected to that cable is unable to use the network. A star topology is scalable.

What are the disadvantages of a mesh network?

Disadvantages Of A Mesh TopologyComplexity. Each node needs to both send messages as well as act as a router, which causes the complexity of each node to go up pretty significantly. … Network Planning. … Latency. … Power Consumption.

Which of the following is a secondary memory device?

Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are the hard disk and optical disks. The hard disk has enormous storage capacity compared to main memory.

Which topology has highest reliability?

Mesh topologyMesh topology can handle high amounts of traffic, because multiple devices can transmit data simultaneously. A failure of one device does not cause a break in the network or transmission of data.
