It consists of many lines that has different widths and spaces. They either represent the letter or a number. These are mainly used for the representation of data in the machine understandable format.
For example an UPC-A bar codes has 12 numbers. The numbering system is represented by the first digit. The manufacturer will be represented by the next five digits in it.

Answer:
b. typically contain more circuits in the network than in star or ring networks
Explanation:
In mesh architecture, all computers are connected to each other. In mesh all nodes connect directly and non hierarchical to each other so as  to efficiently route data.
Mesh combines the benefits of both ring and star networks. It  usually provide relatively short routes through the network (compared to ring networks) and provide  many possible routes through the network to prevent one circuit from becoming overloaded (as compared to star network).  Mesh network uses decentralized routing with each network performing its own routing.
Mesh network typically contain more circuits in the network than in star or ring networks and are more expensive than ring networks
