Ethernet / LAN - Toughbook FZ-40
Panasonic Toughbook 40 Ethernet / LAN
All models of the Panasonic Toughbook FZ-40 come with a super-fast Gigabit (10/100/1000) Ethernet / LAN port. Ethernet is a computer networking technology that is most commonly used to connect to a wired Local Area Network (LAN). Additionally, an optional 2nd Ethernet port via the rear xPAKS is also available.
The standard ethernet port that we use today in most consumer products began to appear on devices in the late 1980s. Since its introduction, ethernet speeds have increased significantly but have always retained a good deal of backward compatibility while being refined to support higher bit rates and longer link distances.
10BASE-T - 10Mbit/s
100BASE-T - 100Mbit/s
1000BASE-T - 1000Mbit/s (1Gbit/s)
The most common references you will encounter when using ethernet is 10/100/1000 Ethernet or Gigabit Ethernet. Both references are the same and indicate an ethernet speed of 1 Gbit/s.
