- Network Layer Which tells us how compters are arranged and how tasks are allocated to computers
- Types of Network Architecture
- Peer to Peer architecture
- Client Server Architecture

- Advantages of Peer to Peer Architecture
- Cheaper because it hasn't any server
- setup easy
- maintainance easy
- single failure don't disturb all
- Disadvantages of Peer to Peer Architecture
- Security Issue
- Can't take the backup of data
- Server is not present so above two are problems

- Advantage of Client Server Architecture
- centrallised system through which back up can easily be done
- better security
- entire system maintained by server
- also increase the speed of resource sharing
- Disadvantages of Client Server Architecture
- Server failure cause unaccessibilty of the resource
- expensive (ec2,lambda)
