Bus # All computers connected together in-line or on a bus. Not fault tolerant Ring # All connected in a loop or ring. Not fault tolerant Star # All devices connected to a hub Fault tolerant Hybrid # Early network systems shrank the bus and ring into a box. Physical topology # Physically how the network looks. Logical topology # Logically how the network functions. ...

SSH
November 11, 2020
Secure Shell (SSH) # Allows a terminal or client to connect to a host terminal with data encrypted as it traverses the network. Protocol: TCP Port: 22 Replaced telnet SSH servers use public-key cryptography and challenge-response authentication . Process: # Server sends public key to client After the client receives the key, it creates a session ID and encrypts it with the public key. The server decrypts the session ID and uses it in all data transfers going forward. ...
Subnetting
October 26, 2020
Subnetting # Subnetting is the process of designating some high-order bits from the host part as part of the network prefix and adjusting the subnet mask appropriately. This divides a network into smaller subnets. The following diagram modifies the subnet mask example by moving 2 bits from the host part to the network prefix to form four smaller subnets each one quarter of the previous size. Binary form Dot-decimal IP address 11000000. ...
IPv4
October 21, 2020
Internet Protocol version 4 (IPv4) is the fourth version of the Internet Protocol (IP). It is one of the core protocols of standards-based internetworking methods in the Internet and other packet-switched networks. IPv4 was the first version deplyed for production on SATNET in 1982 and on the ARPANET in January 1983. It is still used to route most Internet traffic today, despite the ongoing deployment of a successor protocol, IPv6 . ...
Multiple Types of Gigabit Ethernet
October 17, 2020
You can use dedicated media converters to connect any type of Ethernet cabling together. Gigabit Interface Converter (GBIC) # Standard modular port to convert various types of Ethernet Small Form-Factor Pluggable (SFP) # Much smaller transceiver but same as GBIC in the sense that hot-swappable and support all same networking standards.
