CIS 150 Chp 13 Helpdesk Quiz
When my friend connects to my computer, how is data transferred?
Computers communicate efficiently using the communication methodology called packet switching.
Does the IP address remain the same or can it change automatically?
The IP address changes automatically if your computer has a dynamic IP address. A dynamic IP address is a temporary IP address and is assigned by your ISP when your computer connects to the internet.
But how do computers get the IP address from a domain name?
Computers consult the domain name system (DNS) server. The DNS server contains a mapping of domain names with their corresponding IP addresses.
How do packets travel through the Internet?
Packets are routed using Transmission Control Protocol/Internet Protocol (TCP/IP). TCP/IP is a suite of protocols used to route packets over the Internet.
What if the ISP's web server cannot locate the IP information on the default DNS server?
The default DNS server contacts one of the DNS servers. A root DNS server knows the location of all the DNS servers that contain the master listings for an entire top-level domain.
If data is broken into chunks and sent over various routes at the same time, how do these packets reach their destination?
The packets contain destination information and are reassembled when they all reach the destination.
Is there an alternative to remembering IP addresses?
Yes, you can use a domain name. A domain name is simply a name that takes the place of an IP address, making it easier to remember.
what is an IP address and where I can find the IP address for my computer?
an IP address is a unique number identification assigned to each computer, server, or device connected to the internet. To find your IP address, go to Google and type "what is my IP?"
