Of course that’s not all: Next, you could also connect your printer, smartphone or TV to the router so that these devices are also connected to the Internet. Now you have connected different devices to each other via a central access point and created your own network.
The devices can also communicate with each other without having to establish a direct connection to each device. For example, you can send a print job to a Wi-Fi-enabled printer without first connecting the printer to the computer using a cable.
In addition, many offices only have one printer or a few printers that are shared by everyone. Without a network, the IT department would have to connect every single computer to the printer, which is difficult to implement from a technical standpoint.

They can perform regular data backups and enforce security measures, such as multifactor authentication, across all devices collectively.
The Domain Name System (DNS) is a critical component of computer networking. It converts easily recognizable domain names, such as , into numerical IP addresses that computers use to identify each other on the network.
Computer networks are especially beneficial for larger and globally spread-out organizations, as they can use a single common network to connect with their employees.
A variety of protocols and algorithms are also used to specify the transmission of data among endpoints.
Devices attached to a computer network use IP addresses that are resolved into hostnames through a domain name system server to communicate with each other over the Net and on other computer networks.

Transport layer. This layer ensures the stable, 男同网 sequenced and error-free delivery of data packets. It achieves this by swapping acknowledgment of data reception and retransmitting lost or dropped packets. Typical protocols used at the transport layer include TCP and User Datagram Protocol.
