(d) Ethernet Cable An Ethernet cable is used to connect a hub and devices like Network Interface devices.
You can use UTP (Unshielded Twist Pair) and STP (Shielded Twist Pair) Ethernet cables for
noise suppression as well as different types of Ethernet cables for different transfer rates.
Select which Ethernet cable is most suitable for your environment.
(e) Network Interface The Network Interface is a system that can control the network. This is implemented in the
printer (f ). It can be implemented in a computer or you can add this system by inserting a
network interface card or using an adapter. The Ethernet cable should be inserted into the
LAN port of the Network Interface enabled computer or device.
A unique ID is given to every network interface. This is known as a MAC address. The Mac
address consists of a 12 digit hexadecimal number. The first half of the ID number is given
to a Network Interface sales company from an institution that manages MAC addresses,
and the rest is used by the Network Interface sales company to create unique address and
make sure there is no overlap.
Glossary
❏ IP address
When sending signals through a hub, an IP address is necessary to distinguish which device is which to deliver
the signals. As an address is essential when sending letters by post, an IP address is essential for network
communication to receive signals. IP is an abbreviation of Internet Protocol. The IP address is a combination of
the network address to which a computer or device is connected to and the host address itself.
❏ Assigning IP Address
IP addresses cannot overlap, so a unique IP address is assigned in the network to which the device belongs.
IP addresses are divided into two groups; Global IP addresses and Private IP addresses. To connect to the
Internet, you need a global IP address. These are managed by global institutions and provided to Internet
providers. The provider assigns the IP address to the contractor's devices.
When using a network in a local area such as a home or office, a private IP address that is only available in the
closed network is assigned to each device. The device playing the role of a doorway to the network has a global
IP address and it converts the private IP address and global IP address to give access to the Internet for devices
that only have a private IP address.
Devices playing the role of a doorway to the network have a function called DHCP and this assigns the IP
address to devices dynamically, or a provider or network administrator assigns a static IP address manually. If a
device has an IP address which is dynamically assigned, it may be changed when connection fails or reconnects.
If this is inconvenient, you can get a static IP address from a provider or network administrator.
❏ Default Gateway
A device which converts data to alternately communicate with an external network such as the Internet is called
a Gateway. A router acts as a gateway when connecting to the Internet from a home or office network using
Ethernet or Wi-Fi. The router's IP address is known as the Default Gateway.
❏ Subnet Mask
The subnet mask is a numerical value which distinguishes between the network address and the host address of
the IP address. You can find the breakpoint of network address and host address by masking the IP address with
the subnet mask.
❏ Ethernet Communication Standard
Ethernet has standards such as 1000BASE-T, 100BASE-TX, and 10BASE-T based on the transfer rate,
transmission medium, transmission mode and so on. Each standard has a communication mode that must
match the hub and device's communication mode to be used.
Networks Without Cables (Wi-Fi)
Wi-Fi uses radio waves instead of an Ethernet cable and communicates through access points.
