Depending on the type of network, packets may be referred to by another name: frame block cell segment Next, learn about the parts of packets and an example of how packets are applied. I've heard that data travels in packets on a computer network. What is a packet, and why do network...
A packet with an IP header can be referred to as an "IP packet." An IP header contains important information about where a packet is from (its source IP address), where it is going (destination IP address), how large the packet is, and how long network routers should continue to ...

Packets are transmitted over a network using various protocols. The internet protocol (IP) is a fundamental protocol that governs the transmission of packets on the internet. IP assigns each packet a unique address, known as an IP address, which helps routers direct the packets towards their dest...
ICMP:The Internet Control Message Protocol (ICMP) reports errors and provides status updates. For example, if a router is unable to deliver a packet, it will send an ICMP message back to the packet's source. IGMP:The Internet Group Management Protocol (IGMP) sets up one-to-many network co...
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.
Network Availability = (Total Uptime / (Total Uptime + Total Downtime)) × 100% The numerator represents the time the network was operational, while the denominator includes both operational time and downtime. The result is expressed as a percentage, with higher values indicating greater network ...
Network traffic is the data moving across a computer network at any given time. Learn how monitoring traffic can improve network performance and security.
Packet switchingis a networking technology that switches use to forward data frames through a network based on their destination address, rather than using a dedicated circuit for each communication. This allows devices to communicate simultaneously and independently on the same network, facilitating a ...
Network topology is the diagramming of a network to map the way nodes on a network, including switches and routers, are placed and interconnected.
