this new learning is teaching how to configure an internet software

1. NETWORK CONFIGURATION
AND SIMULATION

2. What is “NETWORK CONFIGURATION” ?
 Network configuration is the process of setting a network's controls, flow and
operation to support the network communication of an organization
and/or network owner. This broad term incorporates
multiple configuration and setup processes on network hardware, software and
other supporting devices and components.

3. What is “NETWORK SIMULATION” ?
 Network simulation is a technique whereby a software program models the
behavior of a network by calculating the interaction between the different network
entities (routers, switches, nodes, access points, links etc.).

4. Network Simulation using Cisco packet
tracer:
 Packet Tracer is a powerful network simulator that can be utilized in training
for Network certifications by allowing students to create networks with an
almost unlimited number of devices and to experience troubleshooting without
having to buy real Cisco routers or switches. The tool is created by Cisco Systems.

5. CLI BASIC:
 A command-line interface or command language interpreter (CLI), also known as
command-line user interface
 A CLI (command line interface) is a user interface to a computer's operating
system or an application in which the user responds to a visual prompt by typing
in a command on a specified line, receives a response back from the system, and
then enters another command, and so forth.

6. Configuration File:
 Cisco Router configuration files hold the commands to configure the router.
You can back up, or save, "running-config" file to either NVRAM or a TFTP (Trivial
File Transfer Protocol) server. A persistent copy of Cisco Router configuration file
is called as "startup-config" file.

7. Modes:

8. Show commands:

9. Security Implementation:
 What is Network Security?
Network security is any activity designed to protect the usability and integrity of your
network and data. It includes both hardware and software technologies. Effective
network security manages access to the network. It targets a variety of threats and
stops them from entering or spreading on your network.

10. Managing Configuration files:
•boot buffersize
•boot config
•boot host
•boot network
•clear parser cache
•configure terminal
•configure memory
•configure overwrite-network

11. •parser cache
•service compress-config
•service config
•show configuration
•show derived-config
•show file
•show parser statistics
•show running-config
•show running-config map-class
•show startup-config

12. Configuring Interface:
 Virtual interfaces are software-based interfaces that you create in the memory of
the networking device using Cisco IOS commands. Virtual interfaces do not have
a hardware component such as the RJ-45 female port on a 100BASE-T Fast
Ethernet network interface card.
 Cisco CCNA Configuring an Interface. The type of interface includes things such
as serial, ethernet, fastethernet, gigabitethernet, atm, tunnel, loopback, etc. The
number, slot/number and module/slot/number are numbers used to uniquely
identify an interface on different types of routers.

13.  A network interface is the point of interconnection between a computer and a
private or public network. A network interface is generally a network
interfacecard (NIC), but does not have to have a physical form. Instead,
the network interface can be implemented in software.
 An Interface address is an interface (network )address, a network interface
address, it's just a network address that belongs to an interface. ... Almost all
network addresses e.g. IP addresses, belong to a network interface. (if they're
used at all). Any device with an IP Address, has an IP Address on aninterface.

14.  The interfaces on a router provide network connectivity to the router.
Routersalso have ports for LAN and WAN connectivity. The
LAN interfaces usually include Ethernet, Fast Ethernet, Fiber Distributed
Data Interface (FDDI), or Token Ring. The AUI port is used to provide LAN
connectivity.
