What network links computers in a office building?

What network links computers in a office building?

A local area network (LAN) links computers that are in close proximity—in the same building or office complex. They can be connected by cables or by wireless technology.

How are computers linked to the Internet?

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 hardware device connects a computer to the Internet using the telephone line?

modem
A modem enables a computer to connect to the internet over a telephone line. A modem converts digital signals from a computer to analogue signals that are then sent down the telephone line. A modem on the other end converts the analogue signal back to a digital signal which another computer can understand.

What connects you to the Internet?

Modem. Once you have your computer, you really don’t need much additional hardware to connect to the Internet. The primary piece of hardware you need is a modem. 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 that links the computer to the Internet?

router
A router is a hardware device that allows you to connect several computers and other devices to a single Internet connection, which is known as a home network. Many routers are wireless, which allows you to create a home wireless network, commonly known as a Wi-Fi network.

Is LAN and Ethernet the same?

LAN stands for Local Area Network. A LAN port is also known as an Ethernet port. Both terms refer to exactly the same socket on computers, servers, modems, Wi-Fi routers, switches, and other network devices.

What are network links?

A link (or edge) of a network (or graph) is one of the connections between the nodes (or vertices) of the network. Links can be directed, meaning they point from one node to the next, as illustrated by the arrows in the first figure below. For more information about network links, see the network introduction.

How does dial up access to the Internet work?

Dial-Up (Analog 56K). Dial-up access is cheap but slow. A modem (internal or external) connects to the Internet after the computer dials a phone number. This analog signal is converted to digital via the modem and sent over a land-line serviced by a public telephone network.

Are there different ways to connect to the Internet?

There are many ways a personal electronic device can connect to the internet. They all use different hardware and each has a range of connection speeds. As technology changes, faster internet connections are needed to handle those changes.

Is the Internet a global system of interconnected computer networks?

The Internetis the global system of interconnected computer networksthat uses the Internet protocol suite(TCP/IP) to communicate between networks and devices.
