What 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. Which network component connects a device to transmission media?Which network component connects a device with the transmission media and allows it to send and receive messages? The network interface card (NIC) allows a device to send and receive messages over the transmission media. What type of media transmits multiple signals simultaneously in the communication networks?Frequency Division Multiplexing (FDM): When Frequency Division Multiplexing (FDM) technique is used, multiples signals share the same channel by transmitting at different carrier frequency within the channel’s bandwidth (i.e. they share the bandwidth of a common communication channel). Which type of network connects smart devices or consumer electronics?PANs connect smart devices or consumer electronics within a range of about 30 feet (10 meters) and without the use of wires or cables. What are the types of data transmission?There are two methods used to transmit data between digital devices: serial transmission and parallel transmission. Serial data transmission sends data bits one after another over a single channel. Parallel data transmission sends multiple data bits at the same time over multiple channels. What is transmission medium and its types?Transmission media is of two types are wired media and wireless media. In wired media, medium characteristics are more important whereas, in wireless media, signal characteristics are more important. What are 4 types of transmission media?Transmission Media is broadly classified into the following types: Guided Media: It is also referred to as Wired or Bounded transmission media. (i) Twisted Pair Cable – (ii) Coaxial Cable – (iii) Optical Fibre Cable – Unguided Media: (i) Radiowaves – (ii) Microwaves – (iii) Infrared –. What type of transmission media is fiber optic?Guided transmission media are cables like twisted pair cables, coaxial cables, and fiber optic cables. Unguided transmission media are wireless, such as infrared, radio waves, and microwaves. Which type of network topology connects multiple devices?The mesh topology connects all devices to each other. When every device is connected to every other device, a failure of any cable or device along a connection does not affect the network. The mesh topology is used in WANs that interconnect LANs. How do computers connect to other computers?Within the network your computer can communicate with other computers that are interconnected with an Ethernet or a switch to the same network. The Ethernet cable is a common medium for every computer in the network. Switch can be used to split the wired network. What are the types of media in computer network?There are three general classes of media types: coaxial cable, twisted pair and fiber optic cable. Which 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. What uses Wi-Fi?Wi-Fi allows local area networks (LANs) to operate without cables and wiring, making it a popular choice for home and business networks. Wi-Fi can also be used to provide wireless broadband Internet access for many modern devices, such as laptops, smartphones, tablet computers, and electronic gaming consoles. Which of the following topologies connects each network device to a central hub?Star topologies connect each device on the network to a central hub. What is transmission medium in computer network?Computer NetworkComputer EngineeringMCA. The transmission medium can be defined as a pathway that can transmit information from a sender to a receiver. Transmission media are located below the physical layer and are controlled by the physical layer. Transmission media are also called communication channels. Which type of media are physical?Examples of physical media include twisted-pair copper wire, coaxial cable, multimode fiber optic cable, terrestrial radio spectrum and satellite radio spectrum. Physical media fall into two categories: guided media and unguided media. What is the term used to connect a device to a network that has an IP address group of answer choices?DHCP definition DHCP stands for dynamic host configuration protocol and is a network protocol used on IP networks where a DHCP server automatically assigns an IP address and other information to each host on the network so they can communicate efficiently with other endpoints. What are network transmission devices?Network Transmission Devices are those types of device which is used to share the data and data resources via physical wired. These devices are simple connectors and evolve in complexity and sophistication. Which of the following topologies connects each device to a trunk cable?The bus topology connects all devices to a trunk cable. How network devices are connected?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. Which device that connects to a network without the use of cables?A device which can be connected to a network without using cable is called wireless device. What is topology in computer network and its types?Network topology refers to the physical or logical layout of a network. There are two types of network topologies: physical and logical. Physical topology emphasizes the physical layout of the connected devices and nodes, while the logical topology focuses on the pattern of data transfer between network nodes. Which of the following topologies connects each device to a neighboring device correct answer?You have a small network that uses a hub to connect multiple devices. What physical topology is used?. What transmission means?: the act or process of sending electrical signals to a radio, television, computer, etc. : something (such as a message or broadcast) that is transmitted to a radio, television, etc. : the act or process by which something is spread or passed from one person or thing to another. Which device is used in Internet?The primary piece of hardware you need is a modem. The type of Internet access you choose will determine the type of modem you need. Dial-up access uses a telephone modem, DSL service uses a DSL modem, cable access uses a cable modem, and satellite service uses a satellite adapter. Which device allows you to connect two computers to one network?a) HUB is the correct answer. Network hub is a device that allows you to connect multiple computers to a single network device. With a network hub, you can connect multiple computers to communicate with each other over a network. What WAN stands for?Wide Area Network (WAN). What is topology in computer and its types?Geometric representation of how the computers are connected to each other is known as topology. There are five types of topology – Mesh, Star, Bus, Ring and Hybrid. What allows computers to talk to each other?Transmission Control Protocol/Internet Protocol (TCP/IP) is the backbone of the Internet and the true language computers use to talk to each other. Essentially it’s a set of standards for sending information from a computer’s network card, through transmission lines to another network card. What is a modem connected to?Your modem connects to one port on the router—usually (but not always) labeled “Wide Area Network,” or “WAN”—and all of your devices connect to the other ports, or wirelessly over the Wi-Fi standard. Which type of network uses a central switch to connect computers?In a star network each device on the network has its own cable that connects to a switch or hub.
What is switch and hub in networking?Hub and Switch are the network connecting devices, both help to connect various devices. Hub works at the physical layer and transmits the signal to the port. Switch route the information and send it over the network.
Which topology uses hub or switch as a central device?In the star topology, all the computers connect with the help of a hub. This cable is called a central node, and all other nodes are connected using this central node. It is most popular on LAN networks as they are inexpensive and easy to install.
What type of device is a network hub?Network hubs are categorized as Layer 1 devices in the Open Systems Interconnection (OSI) reference model. They connect multiple computers together, transmitting data received at one port to all of its other ports without restriction. Hubs operate in half-duplex.
