What else can I help you with?
Why is data uploaded as you download?
Data is transmitted in packets. TCP/IP has to respond to each packet. TCP allows for the sending side to know that the packet was received. If there is a malfunction, it can retransmit the packet.
When more than one application is running on a server how does IP know which service should be presented a data packet?
The port number lets IP know which service should be presented a data packet.
How does a host know a data packet was not recieved?
When the TCP/IP protocol is used they use what is called a 3 way handshake. If UDP protocol is used it is connectionless which means there is no guarantee of packet arrival. Here is a link with more information: http://www.inetdaemon.com/tutorials/internet/tcp/3-way_handshake.shtml
How does the access point know if a wireless data packet is intended for its network?
Usually IP addressing is used.
How does IP know which service should be presented a data packet when more than one application is running on a server?
By the Port Number
Why was it good that annemarie did not know what was in the packet?
Becaus she did not want to know
How does the TCP layer in the network software know that it has received all the parts of a message?
Each packet is numbered. Kinda like: part 1 of 5 part 2 of 5 part 4 of 5 part 5 of 5 Straight away its obvious we are missing packet 3. So the destination sends a request back to the sender for packet 3 again.
Reaction for the dawn of the net?
Before a message is received by the recipient,it has to go through a lot of processes. The UDP packet or the Universal Datagram Protocol , TCP packet or the Transmission Control Protocol packet and, ICMP packet or the Internet Control Message Protocol are the protocols in which messages are divided into packets before they are sent. Every packet contains the IP address of the sender, IP address of the receiver and the message from the sender. The router guides the packets where to go. Some packets are rejected when they do not contain the required information. The firewall filters the packets coming from the web server. As the message is received by the recipient, the packets are recycled and are used again when the receiver responds to the message he/she received. These are the information that I got from the recap of our instructor but I still have something in my mind, I just don't know how to express it and I don't know the term! If only I wasn't sleepy, I would have had a better understanding of the video, then again the video was great and it's very educational especially to those who want to know what happens and how things work in the network.
Why is important to analyze data check and identify problems on the LAN?
If you are using a guaranteed reliable delivery method for transport such as TCP, each side (sender-receiver) has to be checking for successful transport of a packet. If the packet was not received correctly the sender needs to be notified so it can retransmit it. It is only important for these things if you are using a protocol that insists on reliability. There are other transport models that don't care about the reliability of the transfer and don't have to check or identify problems.
What is an arp request packet for?
ARP stands for Address Resolution Protocol. This is IP's way of requesting a MAC address (or hardware address) from a host located at a certain IP address. In order for a host on a network to send a unicast packet across the network, it must know both the source and destination MAC addresses. ARP is used to obtain a MAC address similar to the way DNS is used to obtain an IP address from a domain name (www.anydomain.com).
How does data know which way they are supposed travel in a cable?
From the source. Wherever the data leaves from. For example, when I click "Post This Answer", the packets that include this answer leave my laptop and go to my router. They then go to my ISP, which looks at them and then sends them to wiki.answers.com. Wiki.answers.com then reads the packet and automatically edits this page to include the answer.
