    • What are network interconnection devices?

    The switch is a relatively new network device that has replaced both hubs and bridges in LANs. Switches can be used to connect together a number of end-user devices such as workstations, or to interconnect multiple network segments. A switch that interconnects end-user devices is often called a workgroup switch.

    What is a communications device?

    A communication device is a hardware device capable of transmitting an analog or digital signal over the telephone, other communication wire, or wirelessly. Other examples of communication devices include a network interface card (NIC), Wi-Fi devices, and an access point.

    What is the use of repeater?

    A network device used to regenerate or replicate a signal. Repeaters are used in transmission systems to regenerate analog or digital signals distorted by transmission loss. Analog repeaters frequently can only amplify the signal while digital repeaters can reconstruct a signal to near its original quality.

    What is NIC card used for?

    Short for Network Interface Card, the NIC is also referred to as an Ethernet card and network adapter. It is an expansion card that enables a computer to connect to a network; such as a home network, or the Internet using an Ethernet cable with an RJ-45 connector.

    What is meant by Ethernet adapter?

    Definition of: Ethernet adapter. Ethernet adapter. Also called a “network interface card” (NIC), an Ethernet adapter is a card that plugs into a slot on the motherboard and enables a computer to access an Ethernet network (LAN). In the past, desktop computers always used cards.

    What is a modem on a computer?

    A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.

    How many types of modems are there?

    There are two different types of modem: Ethernet modems that plug into the network card in the computer, and wireless modems that connect to a computer using a wireless LAN (WLAN). Some modems offer dual Ethernet and USB connection. There are also routers with integrated ADSL modem.

    What is the difference between a modem and router?

    The two major components in a small computer network are a modem (cable or DSL) and a wireless router. The router is wired to the modem, and the modem is wired to the cable company’s coaxial cable or the telephone company’s DSL phone line. For Internet access via satellite, the router is wired to a satellite modem.

    Do you need a router if you have WIFI?

    To establish WiFi in your home, all you need is either a modem connected to a wireless router, or a wireless gateway, which is a modem and wireless router in one unit (see What is a Wireless Gateway? for more information). A WiFi-capable device can then use this signal to connect to the Internet.

    Can a modem also be a wireless router?

    Today, since most homes include multiple wireless devices, many people now have wireless routers that provide Internet access to all connected devices. Ethernet ports – If your modem includes Ethernet ports on the back, it also doubles as a router, though this does not guarantee it supports Wi-Fi.

    Can I use a router without a modem?

So yes, you can use a network router without a modem but it only let’s you use your own devices and no access to the world wide Web of network routes.

    What is the difference between WIFI router and modem?

    A wireless modem is a device that is able to connect to a wireless network as provided by an ISP. Wifi routers are devices that perform the same functions of a normal router only wirelessly. They forward data packets along networks and they connect different networks and act as a gateway.

    How does wifi work in your home?

    WiFi is a technology that uses radio waves to provide network connectivity. A WiFi connection is established using a wireless adapter to create hotspots – areas in the vicinity of a wireless router that are connected to the network and allow users to access internet services.

    What is the difference between a WIFI router and a modem?

    In order for devices on the network to connect to the Internet, the router must be connected to a modem. Therefore, most routers have a specific Ethernet port that is designed to connect to the Ethernet port of a cable or DSL modem. A modem is a device that provides access to the Internet (see below).

    What is a WIFI router used for?

    A wireless router is a device that performs the functions of a router and also includes the functions of a wireless access point. It is used to provide access to the Internet or a private computer network.
