To access Cisco IOS for configuring network devices, you typically connect via a console cable to the device's console port or remotely through SSH/Telnet if the device is already configured for network access. Once connected, you enter privileged EXEC mode by typing enable, and from there, you can enter global configuration mode using the configure terminal command. Navigation is done using command-line interface commands, and you can utilize context-sensitive help by pressing the question mark ? to see available commands or options. To save configurations, use the write memory or copy running-config startup-config commands.

When using the controlled access method, network devices take turns, in sequence, to access the medium.
The Access Layer
Controls the hardware devices and media that make up the network
A network switch connects devices on a network, allowing them to communicate and access shared resources like files and printers. It operates at the data link layer of the OSI model and uses MAC addresses to forward data to the appropriate devices. By efficiently managing data traffic, switches enhance network performance and reduce collisions, enabling seamless connectivity among all devices.

An access point is a device such as a WLAN or modem which permits wireless devices to connect to a network.
If I am reading your question correctly, I would imagine it is because the computer is not on the same network... **The computer has an invalid default gateway address**
Basically just sets access levels of users or classes of users to different content on network devices.
Network Address Translation (NAT) enhances security by masking the internal IP addresses of devices on a home network. When devices communicate with the outside world, NAT translates their private IP addresses to a single public IP address, making it difficult for outsiders to directly access individual devices. This adds a layer of anonymity and helps prevent unauthorized access, as external requests cannot easily identify or reach specific devices within the network. Additionally, NAT simplifies the management of IP addresses, further bolstering network security.
Three types of intermediary devices include routers, switches, and access points. Routers connect different networks and direct data packets between them, while switches connect devices within the same network, facilitating communication by forwarding data to the appropriate device. Access points enable wireless devices to connect to a wired network, expanding network coverage and accessibility.
