+# Computer Networks
+
+Computers can exchange data if they are connected which each other.
+
+This means that they can share resources, like:
+- Hardware resources
+- Data
+- Programs
+
+in #client-server-architecture, a computer (server) hosts, delivers, and manages resources and providers services to clients trough computer networks.
+
+Examples: gameservers, webservers, email servers, etc...
+
+- Applications require a medium/structure for exchanging messages/data therefore we need a **network**
+- A group of interconnected computers is called a network.
+- Computers in a network can operate independently.
+
+There are different types of computer networks: [[Network Types]]

+# Network Types
+
+The interconnection between computers in a network can be done in 2 ways
+
+## Broadcast network
+![[broadcast-network.png]]
+
+In a broadcast network, every message ([[Packet]]) is sent to every client on the network. Only intended recipients read the packet. Other clients will ignore.
+
+### Disadvantages
+- In a broadcast network you cant send multiple messages at the same time ([[collision problem]])
+- Suffers from heavy load
+- Cannot scale in size.
+
+## Point to Point network
+![[point-to-point-network.png]]
+
+[[Packets]] in point-to-point networks are sent from one node to the other until the destination is reached.
+
+Preferably the shortest path is taken.
+
+## When use what
+
+**Smaller Networks**
+[[#Network Types#Broadcast network]]
+Lighter traffic and lower possibility of collision (smaller dimension).
+
+**Bigger Networks**
+[[#Network Types#Point to Point network]]
+Suits better.
