Study Notes
Client and Service
- A client is defined as a computer that requests a service from another computer or server.
Network Packets
- A network packet consists of two main types of information: control information and user data.
- Control information helps guide the packet through the network, while user data is the actual content being transmitted, such as an email message (considered a payload).
Network Connections
- Computers are interconnected via networks, which enable them to communicate and share resources.
- Various devices such as printers, smartphones, laptops, and tablet computers can be connected to a network.
Addressing and Structure
- A hierarchical addressing scheme is utilized to uniquely identify computers on a network, featuring different components that signify a device's location.
- This addressing scheme is specifically used for IP addresses.
- Networks are structured such that Wide Area Networks (WANs) encompass multiple Local Area Networks (LANs).
WAN Definition and Disadvantages
- WAN stands for Wide Area Network, which can span extensive geographical areas, potentially reaching sizes comparable to the Internet.
- Key disadvantages of networks include susceptibility to intrusion, allowing network intruders access to all connected devices, and the high costs associated with network setup.
Causes of Failure and Packet Path
- The most frequent cause of network failure is human error, which can lead to various issues.
- The typical path of a network packet over the Internet follows a sequence: sender → router 1 → router 2 → router 3 → receiver.
Characteristics of Network Packets
- Network packets carry control information and user data, allowing them to traverse the network effectively.
- They are essential elements sent across the network, contributing to overall communication.
- The letters LAN represent Local Area Network, highlighting a smaller-scale networking model compared to WANs.
