Resources that can be shared in a computer network include: hardware, software, data, and communication channels. The sharing of hardware resources can improve equipment utilization and avoid repeated investment in equipment; the sharing of software resources and data resources can make full use of existing information resources, reduce labor in the software development process, and avoid repeated construction of large databases.

Resources that can be shared in a computer network include: hardware, software, data, and communication channels.
Computer network refers to the connection of multiple computers and their external devices with independent functions in different geographical locations through communication lines. The management of network operating systems, network management software and network communication protocols A computer system that realizes resource sharing and information transfer under and coordination.
Resource Sharing in Computer Networks
Resource sharing is one of the main purposes for people to establish computer networks. Computer resources include hardware resources, software resources, data resources and communication channels.
Sharing of hardware resources can improve equipment utilization and avoid repeated investment in equipment, such as using a computer network to establish a network printer.
The sharing of software resources and data resources can make full use of existing information resources, reduce labor in the software development process, and avoid repeated construction of large databases.
The sharing of communication channel resources means that the same channel can be used by multiple users at the same time.
In actual work, it is often encountered that multiple users (computers or terminals) want to connect to a host at the same time. If each user uses an independent channel to connect to the host, it often consumes a lot of communication line resources. Therefore, channel sharing should be used whenever possible. Channel sharing can improve the utilization of channel resources.
Extended information:
The communication channel is the path for data transmission. In the computer network, the channel is divided into physical channel and logical channel . The physical channel refers to the physical path used to transmit data signals, which is composed of the transmission medium and related communication equipment; the logical channel refers to the logical path realized by both parties sending and receiving data signals through intermediate nodes on the basis of the physical channel, consisting of This is a logical path formed by transmitting data signals.
