TCP does require some overhead. This overhead is used to fulfill several useful functions, such as ensuring that all data is sent, but the overhead has its "costs" with respect to efficiency. In cases where reliability is less important than speed, other alternatives (often based on UDP) are used.
What else can I help you with?
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 IP know which service should be presented a data packet when more than one application is running on a server?
By the Port Number
What are the advantage of circle network?
A circle network, often known as a ring network, offers several advantages, including efficient data transmission, as each device has a dedicated connection to two other devices, minimizing the chances of packet collisions. Additionally, it is relatively easy to install and configure, making it suitable for small to medium-sized networks. The network can be easily expanded by adding more devices without significant disruption. However, one drawback is that if one device fails, it can disrupt the entire network unless redundancy is built in.
Why do you need to collect more data to obtain reliable data?
The more data you have, the more accurate your information. If you have a large amount of evidence of one result, it makes it look correct.
What is a unit of data consisting of one or more characters?
field
Is more efficient than TCP for carrying messages that fit within one data packet?
UDP
What is the packet data unit?
Probably one 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.
What is the term used to describe a discrete unit of data that is sent from one node to another over the network?
Packet
What is data broadcasting in terms of a LAN?
A broadcast packet is sent and received by all systems on a LAN; it can contain any kind of data. The more broadcasting that a LAN does, the slower it will be overall since every device has to read the packet.
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
The term bit is the combination of what two words?
The term "bit" is short for one data packet. A "byte" is 8 data "bits".
When more than one application is running on a server how does IP know which service should be presented an incoming data packet?
When multiple applications are running on a server, the operating system uses ports to distinguish between them. Each application listens on a specific port number, which is part of the transport layer protocol (like TCP or UDP). When an incoming data packet arrives, the server checks the destination port number in the packet's header and forwards the packet to the corresponding application based on that port. This way, the server can effectively route incoming data to the correct service.
Explain the difference between a PDU and a datagram?
A PDU (Protocol Data Unit) is defined by which layer it is in. In the physical layer and network layer, it is synonymous with the packet, in the data link layer, it is the frame. In the transport layer, it is a datagram for UDP. A datagram holds one or more PDU's, as it is the basic unit of transferring information via packet switching.
What is Integrated Check Vector?
Integrated Check Vector (ICV) is a cryptographic checksum used in network communication to verify the integrity of data packets. It is appended at the end of a packet and is calculated based on the payload data using a specific algorithm. When a packet is received, the receiver calculates its own ICV and compares it to the one included in the packet to ensure that the data has not been altered during transmission.
What is packet?
In computer networking, a packet is a segment of data that is sent over a network from one device, including a computer, to another device. It contains the size, data, type, source. and destination that helps it get to the right destination.
How do you calculate the checksum of ICMP packet?
To calculate the checksum of an ICMP packet, you first need to create a pseudo-header that includes the source and destination IP addresses, the protocol number (1 for ICMP), and the length of the ICMP packet. Then, concatenate this pseudo-header with the ICMP packet data. The checksum is computed by performing a bitwise one's complement sum of all 16-bit words in the combined data, followed by taking the one's complement of the final sum. Finally, the calculated checksum is inserted into the ICMP packet's checksum field.
