There are two main types of modes in router configuration: user mode and privileged mode.

• User mode: Limited access to view router status and basic configurations.

• Privileged mode: Full access to configure, manage, and troubleshoot the router.

• Examples: 'show' command in user mode, 'configure terminal' command in privileged mode.

A Cisco switch is a networking device that connects devices within a local area network (LAN) by using packet switching to forward data to the appropriate destination.

• Cisco switches operate at Layer 2 (Data Link Layer) of the OSI model.

• They use MAC addresses to forward data within a network.

• Cisco switches can have multiple ports to connect various devices such as computers, printers, and servers.

• They can also support advanced features like VLANs, QoS, and security protocols.

Network topology refers to the layout of a network and how different devices are connected.

• Network topology can be physical or logical.

• Common physical topologies include bus, star, ring, and mesh.

• Common logical topologies include peer-to-peer and client-server.

• Each topology has its own advantages and disadvantages in terms of cost, scalability, and performance.

Network topology refers to the layout of a computer network and how different devices are connected.

• Network topology defines how devices are interconnected in a network

• Common topologies include bus, ring, star, mesh, and hybrid

• Each topology has its own advantages and disadvantages

• Examples: Bus topology - all devices connected to a single cable, Star topology - all devices connected to a central hub

To configure connectivity between two routers, you need to set up routing protocols and configure IP addresses.

• Configure IP addresses on each router interface

• Choose a routing protocol (e.g. OSPF, EIGRP) and configure it on both routers

• Ensure both routers are in the same network or have a route to reach each other

• Test connectivity using ping or traceroute commands

A Cisco switch is a networking device that connects devices within a local area network (LAN) and forwards data packets between them.

A network is a collection of computers, servers, mainframes, network devices, and other devices connected to each other to share resources and communicate.

• Networks can be wired or wireless

• They can be local (LAN), wide area (WAN), or global (Internet)

• Networks use protocols like TCP/IP for communication

• Examples include Ethernet, Wi-Fi, and cellular networks

A network is a collection of computers, servers, mainframes, network devices, and other devices connected to each other to share resources and information.

• A network allows devices to communicate with each other, share resources, and access the internet.

• Networks can be wired or wireless, with examples including LANs, WANs, and the internet.

• Networks can be private (intranet) or public (internet), with security measures in place to protect data.

• Networks use protocols like TCP/IP...read more

There are many types of networks, including LAN, WAN, MAN, WLAN, and VPN.

• LAN (Local Area Network) - connects devices within a limited area like a home or office

• WAN (Wide Area Network) - connects devices over a large geographical area

• MAN (Metropolitan Area Network) - covers a larger area than a LAN but smaller than a WAN

• WLAN (Wireless Local Area Network) - uses wireless technology to connect devices in a limited area

• VPN (Virtual Private Network) - creates a secure connection o...read more

A public network IP range is a range of IP addresses that are accessible from the internet.

• Public network IP ranges are assigned by Internet Assigned Numbers Authority (IANA)

• Examples of public IP ranges include 1.0.0.0 to 126.255.255.255 for Class A, 128.0.0.0 to 191.255.255.255 for Class B, and 192.0.0.0 to 223.255.255.255 for Class C

• Public IP addresses are unique and globally routable

Different types of RAM include DDR, DDR2, DDR3, DDR4, and LPDDR.

• DDR (Double Data Rate)

• DDR2 (Double Data Rate 2)

• DDR3 (Double Data Rate 3)

• DDR4 (Double Data Rate 4)

• LPDDR (Low Power Double Data Rate)
