Study Notes
Networking and Number Systems
- High-speed internet services, such as Digital Subscriber Line (DSL) and cable modem access, have transitioned from corporate environments to consumer markets.
- These services are "always on," providing instant access and do not require a connection to be established for each session, resulting in greater reliability and flexibility.
- They have led to the ease of internet connection sharing by small office and home networks.
TCP/IP
- Transmission Control Protocol/Internet Protocol (TCP/IP) is a set of protocols or rules that allow cooperating computers to share resources across a network.
- TCP/IP enables computers to share resources and communicate with each other over a network.
Testing Connectivity with Ping
- The ping command sends multiple IP packets to a specified destination, requesting a reply from each packet.
- Ping is used to test the NIC (Network Interface Card) transmit/receive function, TCP/IP configuration, and network connectivity.
- Internal loopback test:
ping 127.0.0.1
verifies the operation of the TCP/IP stack and NIC transmit/receive function. - Ping can be used to verify:
- Local host and connectivity to the host using the host's IP address.
- Connectivity to the default gateway using the gateway's IP address.
- Connectivity to a remote host using the remote host's IP address.
Network Math
- Binary presentation of data is used to represent alpha-numeric data in a computer.
- The American Standard Code for Information Interchange (ASCII) is the most commonly used code for representing alpha-numeric data in a computer.
