What is used to transfer data packets between two networks?
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets.
When using packet switching packets are always sent over the same route?
When using packet switching, packets are always sent over the same route. File Transfer Protocol (FTP) is used to transmit e-mail messages across the Internet. IPv6 uses six groups of 16-bit numbers. Dynamic IP addressing is accomplished using a DHCP server.
Are devices that transfer packets of data?
Routers. A router is the traffic-control center device that handles the packet transfer process between networks. Essentially, routers determine where to send a data packet and then forward it to the next network point.
What is two or more computers connected using software and hardware so that they can communicate with each other?
When two or more computers are connected together so they can communicate with one another, they form a network. The largest computer network in the world in the Internet.
What is responsible for packet switching?
In connection-oriented packet switching, also called virtual circuit switching or circuit switching, data packets are first assembled and then numbered. They then travel across a predefined route, sequentially. Address information is not needed in circuit switching, because all packets are sent in sequence.
What are the two approaches to packet switching?
There are two common packet switching methods in use:
- Datagram Packet Switching: Each packet is forwarded independently based on the destination address. …
- Virtual Circuit Packet Switching: A route is set up prior to packets being sent.
Which process safeguards data from theft or loss?
