Classify Network Protocols and Communication.
Cisco calls its operating system the Cisco Internetwork Operating System or Cisco IOS.
Basic routing and switching functions
Reliable and secure access to networked resources
Network scalability
Operating system
OS Shell
command-line interface (CLI) or a graphical user interface (GUI) and enables a user to interface with applications.
OS Kernel
communicates directly and manages how hardware resources are used to meet software requirments.
Hardware
The physical part of a computer including underlying electronics
Router user interface
The CIsco IOS software uses a command-line interface (CLI) as the tranditional console environment
Several methods of environment:
Console - a low speed serial connection directly from a computer or terminal
Dialup - connection using a modem or null modem
Telnet - to the router
Purpose of OS
GUI
Use mouse to make selections and run programs
Enter text and text-based commands
CLI on a Cisco IOS switch or router
Use a keyboard to run CLI - based network programs
Use a keyboard to enter text and text-based commands
Distinct variations of Cisco IOS
IOS for switches, routers, and other Cisco netwrking devices
IOS numbered versions for a given Cisco networking devices
Access Methods
1.Console port
2.Secure shell (SSH)
3.Telnet
IOS Modes
User EXEC Mode
"view only" mode.
can be identified by the ">" prompt
Privileged EXEC Mode
require a password from the user before accessing it
can be identified by the "#" prompt
Global Configuration mode
to enter configuration mode, enter the command configure terminal from privileged mode
can be identified by the (config)# prompt following the router name
example, when you enter interface configuration submode, the prompt changes to (config-if)# following the router name
to exit, just enter end or press Ctrl-Z
Configuration Example:
Router # show running config
Router (config )# hostname ‘name'
Router (config )# banner motd # ‘banner’
Router # copy running config startup config
Router (config if)# ip address 192.168.1.1
Router (config ) # enable secret class
Router (config )# interface vlan 20
Router (Config )# interface fa0/1
Network Media:
What is the maximum distance that the media can successfully carry a signal?
When the media is successfull installed.
Into what type of environment will the media be installed?
You can use installation media (a USB flash drive or DVD) to install a new copy of Windows, perform a clean installation, or reinstall Windows 10.
On that website, you can select a version of Windows and create your own installation media using either a USB flash drive or a DVD.
What is the amount of data and the speed at which it must be transmitted?
the amount of data that can be transferred from one point to another within a network in a specific amount of time.
expressed as a bitrate and measured in bits per second (bps).
What is the cost of the media and installation?
Cost Per Install (CPI) is the price to acquire a new customer from paid advertisements. This metric refers to paid installs in contrast to organic installs.
