In networking, a packet is a small segment of a larger message. Data sent over computer networks*, such as the Internet, is divided into packets. These packets are then recombined by the computer or device that receives them. Suppose Alice is writing a letter to Bob, but Bob's mail slot...
What is a packet? Innetworking, a packet is a small segment of a larger message. Data sent over computer networks*, such as theInternet, is divided into packets. These packets are then recombined by the computer or device that receives them. ...
A good example of how this works in practice is when an email is sent using SMTP from an email server. To start the process, the TCP layer in the server divides the message into packets, numbers them, and forwards them to the IP layer, which then transports each packet to the destinati...
Using QoS in networking, organizations have the ability to optimize the performance of multiple applications on their network and gain visibility into the bit rate, delay, jitter, and packet rate of their network. This ensures they can engineer the traffic on their network and change the way tha...
a link state packet, or lsp, is essentially a data message used in networking to exchange information about the connections and statuses between routers. think of it as a digital map that updates in real time, telling each router in the network about the paths it can take to send your ...
Packet sniffing is a technique whereby packet data flowing across the network is detected and observed. Network administrators use packet sniffing tools to monitor and validate network traffic, while hackers my use similar tools for nefarious purposes.
devices to take turns using the signal carrier line. When a device wants to transmit, it checks the signal level of the line to determine whether another data packet is using it. If it's in use, the device waits a few seconds and retries. If it isn't in use, the device transmits....
Packet loss happens when packets of data are unable to reach their final destination. Learn the causes of packet loss and how to fix it.
Parts of a network packet in IPv4 IPv4 is the most widely used version of the Internet Protocol. It incorporates a set of rules that enables devices to connect to the internet, with each connecting device assigned a unique, 32-bit identifier called an IP address. When data is sent between...
Network Packet Structure I've heard that data travels in packets on a computer network. What is a packet, and why do networks use them? 2009 HowStuffWorks Most network packets are split into three parts: Header - The header contains instructions about the data carried by the packet. Thes...
