Updated: 07/06/2021 by A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to allow data sharing. An example of a network is the
Internet, which connects millions of people all over the world. To the right is an example image of a home network with multiple computers and other network devices all connected. The term network topology describes the relationship of connected devices in terms of a geometric graph. Devices are represented as vertices, and their connections are represented as edges on the graph. It describes how many connections each device has, in
what order, and what sort of hierarchy. Typical network configurations include bus topology, mesh topology, ring topology, star topology, tree topology, and hybrid topology. Most home networks are configured in a tree topology that connects to the Internet. Corporate networks often use tree topologies, but they also often incorporate star topologies and an Intranet. What is the difference between public and private networks?Often offered by nearby businesses and other publicly accessible areas, public networks are a convenient way to connect to the Internet.
Note All public networks are less secure than your home network. Even if the websites you visit use encryption, the URLs you visit can be eavesdropped. For this reason, you should not transmit private or sensitive information on a public Wi-Fi network if you can do it elsewhere. If a public network does not require a password, we strongly recommend you do not connect any of your devices to it. Private networks have security measures in place to prevent unwanted or unauthorized connections. Private networks are often used for home, business, school Wi-Fi networks, or mobile hotspots for security and to preserve bandwidth. Advantages of a networkThere are more advantages to a network than disadvantages. In fact, many companies today wouldn't exist without accessing some form of network. Below are the advantages of a network.
Disadvantages of a networkAlthough there are many advantages to a network (mentioned above), there are some disadvantages. Below are the disadvantages of a network.
What was the first computer network?One of the first computer networks to use packet switching, ARPANET, was developed in the mid-1960s and is the direct predecessor of the modern Internet. The first ARPANET message was sent on October 29, 1969. Internet, LAN, Network terms What is it called when computers communicate with each other?Did you know computers talk to each other through their own, unique language? And that language is called TCP/IP. TCP/IP is a set of communications protocols that allow computers to communicate on the Internet.
What is it called when two computers are linked together?When two or more computers are connected together so they can communicate with one another, they form a network.
Which is a device that allows a computer to connect and communicate with other computers?Detailed Solution. Option 1 is correct, i.e. MODEM. A modem is a hardware device that allows a computer to send and receive data over a telephone line or a cable or satellite connection. MODEM stands for modulator-demodulator.
