About Cisco packet tracer
Key Features
Packet Tracer Works-paces: Cisco Packet Tracer has two work-spaces—logical and physical. The logical workspace allows users to build logical network topologies by placing, connecting, and clustering virtual network devices. The physical workspace provides a graphical physical dimension of the logical network, giving a sense of scale and placement in how network devices such as routers, switches, and hosts would look in a real environment. The physical view also provides geographic representations of net-works, including multiple cities, buildings, and wiring closets.
Packet Tracer Modes: Cisco Packet Tracer provides two operating modes to visualize the behavior of a network—real-time mode and simulation mode. In real-time mode the network behaves as real devices do, with immediate real-time response for all network activities. The real-time mode gives students a viable alternative to real equipment and allows them to gain configuration practice before working with real equipment
Interface overview
The layout of Packet Tracer is divided into several components similar to a photo
editor. Match the numbering in the following screenshot with the explanations
given after it:
The components of the Packet Tracer interface are as follows:
• Area 1: Menu bar – This is a common menu found in all software applications;
it is used to open, save, print, change preferences, and so on.
• Area 2: Main toolbar – This bar provides shortcut icons to menu options
that are commonly accessed, such as open, save, zoom, undo, and redo,
and on the right-hand side is an icon for entering network information
for the current network.
• Area 3: Logical/Physical workspace tabs – These tabs allow you to toggle
between the Logical and Physical work areas.
• Area 4: Workspace – This is the area where topologies are created and
simulations are displayed.
• Area 5: Common tools bar – This toolbar provides controls for manipulating
topologies, such as select, move layout, place note, delete, inspect, resize
shape, and add simple/complex PDU.
• Area 6: Realtime/Simulation tabs – These tabs are used to toggle between
the real and simulation modes. Buttons are also provided to control the
time, and to capture the packets.
• Area 7: Network component box – This component contains all of the
network and end devices available with Packet Tracer, and is further
divided into two areas:
° Area 7a: Device-type selection box – This area contains device
categories
° Area 7b: Device-specific selection box – When a device category
is selected, this selection box displays the different device models
within that category
• Area 8: User-created packet box – Users can create highly-customized
packets to test their topology from this area, and the results are displayed
as a list.
Protocols: Cisco Packet Tracer supports the following protocols:
Layer that Cisco Packet Tracer Supported Protocols

Modular Devices: Graphical representations visually simulate hardware and offer the ability to insert interface cards into modular routers and switches, which then become part of the simulation.
