It can either be called a Host or a Node. Either one is correct.
A node is a device connected to a network such as a computer or a game console. (Each device connected to a network is referred to as a node. A node can be a computer, printer, game console, or router.)
STAR Topology
A Network interface card, NIC, or Network card is an electronic device that connects a computer to a computer network, usually a LAN. It is considered a piece of computer hardware. Today, most computers are equipped with network cards.
device driver
A star network.
Each device can be identified by its IP address (assigned for the network and can be subnetted) and its MAC - which is a device identifier supposedly unique to the device.
Yes you can see other computers in a wireless network, each device has it's own unique MAC-address which describes to the computer what type of device is connected to the network. Using the 'Network' feature on the computer gives the person a graphical view of who is connected to the Network, this can be done by going to: Start, 'Network'.
Network attached storage is a device that connects to a network of computers and allows for storage separate than on each computer. This is useful in many businesses because it allows each separate computer to have a way of backing up their files, and also access those files from each separate computer within the network.
They (the computers in the network) connect to each other through a computer protocol (a fancy name of say rules that a computer follow to talk to each other) called bittorrent.
The answer to this question depends on HOW the device is used on the network. If the device is used to store data from other computers it is called a server. If it is used to access data from other computers or the server it is called a client.
Windows and Linux use device letters to identify each storage device on a computer.
Node. A node describes any device that connects to the network.
