Router
Routers connect two separate networks. This means, for example, that you
can connect the local network to another LAN or a WAN. When a PC wants
to send a data packet, this packet must travel over a router. The router uses
the IP address to detect the network it must send the data to. In addition to
connecting to networks, routers can also execute certain control functions,
such as maintaining a simple firewall. In a home network, routers are usually
used to connect the local network to the Internet and to enable simultaneous
Internet access for multiple users.
S
SD/SDHC/SD-XC Card
Secure, digital memory cards that use flash-type storage (non-volatile
storage). Their special shape protects them from wrong insertion into the
card slot. A lateral device for write protection (sliding switch) protects them
from accidental deletion of data. SD cards can store up to 2 GB (SD 1.1
standard) whereas SDHC cards can store up to 32 GB (SD 2.0 standard).
SC-XC cards can store from 32 GB to - theoretically - 2.048 GB (SD 3.0
standard). Information on recommended memory cards can be found in the
Internet (Auerswald:
