Basic terms 4. Latency
"Latency" is used to mean the delay time from when a request for data transmission is issued until when the data actually arrives. A low-latency network takes less time for a "packet", the unit of data transmission, to travel from one network point to another. High-latency networks take a long time to load data, impairing real-time performance when streaming video and audio.
Basic terms 5. LAN
A "LAN" (local area network) is a network used for data transmission by client devices within a geographically limited area. LAN may refer to an office network or a home network. The basic network devices that make up a LAN include a "router" and a "switch", and data transmission is realized by a wired LAN or wireless LAN that conforms to "Ethernet".
Basic terms 6. Modem
A "modem" receives an analog signal and converts it to a digital signal that the client device can understand, and vice versa. A modem connects your home network to your Internet Service Provider (ISP) network and makes the Internet available. Some home networks use a network device that combines the functionality of a modem and a "router."
Basic terms 7. Networking
"Networking" is to enable data transmission between "network nodes" that send and receive data within the network. From home networks to global corporate internal networks, networking enables sharing of data between network nodes.
