Subnet Mask
The subnet mask is a way of augmenting the network address section of an IP address.
A subnet mask represents all network address sections as 1 and all host address sections as 0. The number of bits in
the prefix indicates the length of the network address. The term "prefix" refers to something added to the beginning and,
in this context, indicates the first section of the IP address. When an IP address is written, the length of the network
address is indicated by the prefix length after a forward slash (/). For example, "24" in the address "133.210.2.0/24". In
this way, "133.210.2.0/24" denotes the IP address "133.210.2.0" with a 24-bit prefix (network section). This new network
address section (originally part of the host address) made possible by the subnet mask is referred to as the subnet
address. When you enter the subnet mask, be sure to set the "DHCP" setting to "Off".
TCP/IP (Transmission Control Protocol/Internet Protocol)
TCP/IP is a suite of protocols designed to define the way computers and other devices communicate with each other
over a network.
TCP/IP (IPv6)
TCP/IP (IPv6) is based on the current Internet protocol, TCP/IP (IPv4). IPv6 is the next-generation Internet protocol and
expands the available address space, which resolves the problem of the lack of addresses under IPv4, while also
introducing other improvements such as additional security functionality and the capacity to prioritize data transmission.
USB (Universal Serial Bus) 2.0
A USB interface standard for Hi-Speed USB 2.0. The maximum transfer rate is 480 Mbps. This machine is equipped with
USB 2.0 for high-speed data transfer.
