How do computers communicate with other computers on the same network and on different networks?

How do computers communicate with other computers on the same network and on different networks?

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.

Can PCS on different subnets communicate?

Devices in different subnets can communicate. That is the purpose of a router. Routers route packets between different networks. Even if devices in different networks are on the same layer-2 broadcast domain, you need a router to let the devices communicate at layer-3.

How do two computers communicate on a LAN?

The Ethernet standard is what allows these machines to talk to one another. Each computer (or printer or other device) that is connected to this Ethernet cable is set up to have a unique address, or IP Address.

What are the two ways computers can connect to the network?

1: What are the two ways computers can connect to the network? Answer: Computers and other devices can connect to a network using cables or wirelessly. WiFi is the common wireless technology for a computer network.

What type of communication will send a message to all devices on a local area network?

What type of communication will send a message to all devices on a local area network? Explanation:Broadcast communication is a one-to-all communication.

How can two computers in different network communicate?

Under normal, non-hacker circumstances, the NAT routers at each end would need to have port forwarding enabled for each PC’s private address, or the routers would need to be using one-to-one NAT, to enable the two PCs to communicate via the public addresses. You could also use a VPN between the two PCs to get around the NAT problem.

Can a computer access another computer on the network?

Once two systems are on the same network, they can easily communicate with each other i.e., they can send and receive files from each other, and a user on one computer can access the files on the other computer over the network.

Can a Mac connect to the same network as a PC?

Computers, regardless if they’re Macs or PCs, can all connect to the same network. Once two systems are on the same network, they can easily communicate with each other i.e., they can send and receive files from each other, and a user on one computer can access the files on the other computer over the network.

Can a PC connect to more than one subnet?

The PC’s in the other subnet should be able to communicate with each other. However if they attempt to ping an IP on a different subnet, it won’t work unless the default gateway is setup on the router and some form of routing (static/dynamic) is setup on the router. Having more than one subnet on a LAN used to be more common than it is today.
