Networking Basics

Some computers are independent units, with little need to exchange infor-

mation with other computers near or far. At most, these computers may use

local interfaces such as USB or RS-232 to communicate with printers or

other devices close at hand.

But with a network connection, a computer can reach beyond its local inter-

faces to send and receive information of any kind, over distances large and

small, via wires or through the air. Computers of different types can com-

municate using network protocols supported by all. In a network of embed-

ded systems, each system can communicate with the other systems in the

network, sharing information and sending and responding to requests as

needed. Desktop computers in the network can monitor and control the

operation of the embedded systems.

Many local networks follow the networking standard popularly known as

Ethernet. Ethernet networks are capable and flexible. Many products

designed for use in networks have support for Ethernet built in. A router, or

Networking Basics

• A defined physical interface, to ensure that the output of a transmitting

computer is compatible with the inputs of the receiving computers. For

Ethernet networks, the Ethernet standard specifies this interface.

• Cables or wireless transceivers to connect the computers. Ethernet net-

works have several options for cables. An Ethernet interface may also

connect to a device called a wireless access point, which enables the

embedded system to access a wireless network.

The computers in the network must also agree on the following aspects of

sharing the network:

• Rules for deciding when a computer may transmit on the network.

When multiple computers share a data path, whether in a cable or wire-

less medium, the computers need to know when the path is available for

transmitting. The Ethernet standard contains rules that specify when a

computer may transmit.

• A way of identifying a transmission’s intended destination. In Ethernet

networks, multiple computers may receive a message intended for one

computer in the network. When a message arrives at a computer’s net-

work interface, the computer needs to know whether the message is

intended for itself or another computer. Every communication in an

Ethernet network includes a hardware address that identifies the Ethernet

interface of the intended receiver. Some communications also use Inter-

net protocols that contain additional addressing information, such as an

addresses that identify the sending and receiving computers on the Inter-

net and a port, or process, that receives the communication at the desti-

nation computer.

• A defined format for the information sent on the network, so a computer

can understand and use the information it receives from the network. In

Ethernet networks, all data travels in structures called frames. Each frame

includes fields for data, addressing, and other information that helps the

data reach its destination without errors. The information in a frame’s

data field may also use protocols that help the receiver of the frame

decide what to do with the received data.
