CISCO OVERVIEW

Cisco is a global pioneer in networking that changes how people interact, communicate and collaborate. Cisco's communication protocols connect individuals, computer devices and computer networks.

Computer networking applies to computer devices like smartphones, desktops, computers, notebooks, and tablets that are linked. An ever-expanding collection of IoT gadgets that connect with each other.

Network topology is used to define a network's physical and logical structure. It maps the way multiple nodes on a network are located and interconnected, including switches and routers, as well as how data flows. To maximize traffic flows, diagramming the positions of endpoints and service criteria helps decide the optimal positioning for each node.


TOPOLOGY

Topology is a well-planned network topology enhances the user experience and helps administrators maximize performance while fulfilling business needs. There are two kinds of network topology which are,

Physical Physical or Underlay is the maps the actual connections in a network, such as wires and cables and the placement of various components.
Logical Logical or Overlay is showed How transmit data within a network, independent of the physical connection between the machines. While the logical network uses physical connections for data transfer, the real data flow is determined by logic, not by physical connections.

NETWORK TOPOLOGY DIAGRAM

Cisco Network Topology Diagrams visualize the topology and structure of telephone and computer networks. IT practitioners and corporate IT teams, network and system managers use them to visually record the topology of Cisco data networks. In order to draw the vector stencils in the Cisco objects libraries that help you to start using software for designing your own Cisco Network Topology Diagrams.

Cisco Object Explanation

  • Routers

    A Router is an inter networking device which operates at OSI Layer 3 and it is also interconnect network segments that passes the data packets between networks based on Layer 3 information

  • Switch

    Switches link LAN segments, use the Mac address to specify the section on which the datagram allows the transmission, and minimize traffic. Switches, usually used in Layer 2, may be classified as stackable or chassis-based.

  • Network Cloud

    The Network Cloud is a wide area network (WAN) or the Internet. Network traffic can pass via private and public connections, based on the service and connections offered. Data can also be distributed by a single Internet Service Provider (ISP) or several ISPs.

  • Personal Computer (VPC)

    The Personal Computer (PC) has only been around for 25 years and has greatly changed the world. Functionality, performance, and storage have greatly increased. With the advent of the Internet. In this tutorial we will use the VPC you can choose the Virtual Personal Computer template
