Module 1 - Communications in a Connected World

Local Networks

Small Home Networks - Small home networks connect a few computers to each other and to the internet.

Small Office and Home Office Networks - The SOHO network allows computers in a home office or a remote office to connect to a corporate network, or access centralized, shared resources.

Medium to Large Networks - Medium to large networks, such as those used by corporations and schools, can have many locations with hundreds or thousands of interconnected hosts.

World Wide Networks - The internet is a network of networks that connects hundreds of millions of computers world-wide.

Mobile Devices

Smartphones are able to connect to the Internet from almost anywhere. Smart phones combine the functions of many different products together, such as a telephone, camera, GPS receiver, media player, and touch screen computer.

Tablets, like smartphones, also have the functionality of multiple devices. With the additional screen size, they are ideal for watching videos and reading magazines or books. With on-screen keyboards, users are able to do many of the things they used to do on their laptop computer, such as composing emails or browsing the web.

A smartwatch can connect to a smart phone to provide the user with alerts and messages. Additional functions, such as heart rate monitoring and counting steps, like a pedometer, can help people who are wearing the device to track their health.

A wearable computer in the form of glasses, such as Google Glass, contains a tiny screen that displays information to the wearer in a similar fashion to the Head-Up Display (HUD) of a fighter pilot. A small touch pad on the side allows the user to navigate menus while still being able to see through the smart glasses.

Connected Home Devices

Many of the items in a home, such as security systems, lighting, and climate controls, can be monitored and configured remotely using a mobile device.

Household appliances such as refrigerators, ovens, and dishwashers can be connected to the Internet. This allows the homeowner to power them on or off, monitor the status of the appliance, and also be alerted to preset conditions, such as when the temperature in the refrigerator rises above an acceptable level.

A smart TV can be connected to the Internet to access content without the need for TV service provider equipment. Also, a smart TV can allow a user to browse the web, compose email, or display video, audio, or photos stored on a computer.

Gaming consoles can connect to the internet to download games and play with friends online.

Other Connected Devices

Smart cars - Many modern cars can connect to the Internet to access maps, audio and video content, or information about a destination. They can even send a text message or email if there is an attempted theft or call for assistance in case of an accident. These cars can also connect to smart phones and tablets to display information about the different engine systems, provide maintenance alerts, or display the status of the security system.

RFID Tags - Radio frequency identification (RFIDs) tags can be placed in or on objects to track them or monitor sensors for many conditions.

Sensors and Actuators - Connected sensors can provide temperature, humidity, wind speed, barometric pressure, and soil moisture data. Actuators can then be automatically triggered based on current conditions. For example, a smart sensor can periodically send soil moisture data to a monitoring station. The monitoring station can then send a signal to an actuator to begin watering. The sensor will continue to send soil moisture data allowing the monitoring station to determine when to deactivate the actuator.

Medical devices such as pacemakers, insulin pumps, and hospital monitors provide users or medical professionals with direct feedback or alerts when vital signs are at specific levels.

types of personal data:

Volunteered data - This is created and explicitly shared by individuals, such as social network profiles. This type of data might include video files, pictures, text or audio files.

Observed data - This is captured by recording the actions of individuals, such as location data when using cell phones.

Inferred data - This is data such as a credit score, which is based on analysis of volunteered or observed data.

The Bit

Computers use binary codes to represent and interpret letters, numbers and special characters with bits. A commonly used code is the American Standard Code for Information Interchange (ASCII). With ASCII, each character is represented by eight bits. For example:

Capital letter: A = 01000001

Number: 9 = 00111001

Special character: # = 00100011

three common methods of signal transmission used in networks:

Electrical signals - Transmission is achieved by representing data as electrical pulses on copper wire.

Optical signals - Transmission is achieved by converting the electrical signals into light pulses.

Wireless signals - Transmission is achieved by using infrared, microwave, or radio waves through the air.

Bandwidth

Bandwidth is the capacity of a medium to carry data. Digital bandwidth measures the amount of data that can flow from one place to another in a given amount of time. Bandwidth is typically measured in the number of bits that (theoretically) can be sent across the media in a second.

Bits per second bps 1 bps = fundamental unit of bandwidth

Kilobyte = Thousands of bits per second kbps 1 kbps = 1,000 bps = 103 bps

Megabyte = Millions of bits per second Mbps 1 Mbps = 1,000,000 bps = 106 bps

Gigabyte = Billions of bits per second Gbps 1 Gbps = 1,000,000,000 bps = 109 bps

Terabyte = Trillions of bits per second Tbps 1 Tbps = 1,000,000,000,000 bps = 1012 bps

Throughput

Like bandwidth, throughput is the measure of the transfer of bits across the media over a given period of time. However, due to a number of factors, throughput does not usually match the specified bandwidth. Many factors influence throughput including:

The amount of data being sent and received over the connection

The types of data being transmitted

The latency created by the number of network devices encountered between source and destination

Latency refers to the amount of time, including delays, for data to travel from one given point to another.

Clients and Server Roles

Servers are hosts that have software installed which enable them to provide information, like email or web pages, to other hosts on the network. Each service requires separate server software. For example, a host requires web server software in order to provide web services to the network. Every destination that you visit online is provided to you by a server located somewhere on a network that is connected to the global internet.

Clients are computer hosts that have software installed that enables the hosts to request and display the information obtained from the server. An example of client software is a web browser, such as Internet Explorer, Safari, Mozilla Firefox, or Chrome.

Peer-to-Peer Networks

In small businesses and homes, many computers function as the servers and clients on the network. This type of network is called a peer-to-peer (P2P) network.

Peer-to-Peer Applications

A P2P application allows a device to act as both a client and a server within the same communication, as shown in the figure. In this model, every client is a server and every server is a client. P2P applications require that each end device provide a user interface and run a background service.

Network Infrastructure

End devices - Computers (workstations, laptops, file servers, web servers), Network printers, Telephones and teleconferencing equipment, Security cameras, Mobile devices (such as smart phones, tablets, PDAs, and wireless debit/credit card readers and barcode scanners)

Intermediate devices - Wireless Router, LAN Switch, Router, Multilayer Switch, Firewall Appliance

Network media - Wireless Media, LAN Media, WAN Media

Which of the following is a low-power, shorter range wireless technology that is intended to replace wired connectivity for accessories such as speakers or a mouse?

Bluetooth

Which of the following is a wireless communication technology that enables a smartphone to communicate with a payment system within a few centimeters away?

NFC

When a network administrator changes the IPv4 and IPv6 address of a computer, which topology diagram will need to be updated?

Logical topology diagram

Module 2 - Online Connections

Mobile Telephones

Mobile phones use radio waves to transmit voice signals to antennas mounted on towers located in specific geographic areas. Mobile phones are often referred to as “cell phones” because the geographic area in which an individual tower can provide a signal to a phone is called a cell.

Cell Phone Network

Currently, 4G still dominates as the current mobile network used by most phones. 4G delivers speeds that are 10 times the previous 3G networks. Introduced in 2019, 5G is the latest standard. It is more efficient than previous standards. 5G holds the promise of delivering 100 times faster speeds than 4G and connecting more devices to the network than ever before.

Global Positioning System

The GPS uses satellites to transmit signals that cover the globe. The smart phone can receive these signals and calculate the phone’s location to an accuracy of within 10 meters.

Wi-Fi

Wi-Fi transmitters and receivers located within the smartphone enable the phone to connect to local networks and the internet. In order to receive and send data on a Wi-Fi network, the phone needs to be within the range of the signal from a wireless network access point. Wi-Fi networks are usually privately owned but often provide guest or public access hotspots. A hotspot is an area where Wi-Fi signals are available. Wi-Fi network connections on the phone are similar to the network connections on a laptop computer.

Bluetooth

Bluetooth is a low-power, shorter range wireless technology that is intended to replace wired connectivity for accessories such as speakers, headphones, and microphones. Bluetooth can also be used to connect a smartwatch to a smartphone. Because Bluetooth technology can be used to transmit both data and voice, it can be used to create small local networks. Bluetooth is wireless technology that allows devices to communicate over short distances. Multiple devices can be connected at the same time with Bluetooth.

Near Field Communications

NFC is a wireless communication technology that enables data to be exchanged by devices that are in very close proximity to each other, usually less than a few centimeters. For example, NFC can be used to connect a smartphone and a payment system. NFC uses electromagnetic fields to transmit data.

LAN Components

Hosts - Hosts send and receive user traffic. A host is a generic name for most end-user devices. A host has an IP address. Examples of hosts are personal computers and network attached printers.

Peripherals - Shared peripheral devices do not communicate directly on the network. Instead, peripherals rely on their connected host to perform all network operations. Examples of shared peripherals are cameras, scanners, and locally attached printers.

Network devices - Networking devices connect other devices, mainly hosts. These devices move and control network traffic. Examples of network devices include hubs, switches, and routers.

Network media - Network media provides connections between hosts and network devices. Network media can be wired, such as copper and fiber optic, or use wireless technologies.

End Device Addressing

IP address - This identifies the host on the network.

Subnet mask - This is used to identify the network on which the host is connected.

Default gateway - This identifies the networking device that the host uses to access the internet or another remote network.

Manual and Automatic Address Assignment

Manual IP Configuration

With manual configuration, the required values are entered into the device via the keyboard, typically by a network administrator. The IP address that is entered is referred to as a static address and and must be unique on the network.

Dynamic IP Configuration

Most end-user devices can be set up to receive network configuration information dynamically. This enables the device to request an address from a pool of addresses assigned by a Dynamic Host Configuration Protocol (DHCP) server located within the network.

Logical Network Information

A diagram called a logical topology illustrates the relevant network configuration information.

Part 4: Basic Switch Configuration

You will perform some basic configuration on a switch using the Config and CLI tabs in Packet Tracer.

Step 1: The Config tab

a. Click Switch0.

b. Click the Config tab.

Note: The Config tab is not always available on physical networking equipment. Some simple devices only have config tabs. The config tab can be useful for basic learning of commands, especially for beginners.

The Config tab shows a list of components that can be configured on this device. We are not going to cover what these components are, as that is learned in a networking course, but we will show how to navigate and use the interface.

c. The Global Settings allows a user to change the name of a device that displays in the workspace. It also allows for changing the internal name shown at the command line prompt as well as buttons for saving, loading, exporting, and erasing configuration files.

Double-click in the Hostname dialog box to highlight the word Switch. Enter Central to replace Switch as the hostname. Packet Tracer will display the IOS commands necessary to accomplish the name change in the Equivalent IOS Commands box. The commands displayed should be as follows:

Switch> enable

Switch# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# hostname Central

Central(config)#

These would be the commands used from the command line interface or CLI to change the hostname. If you did not know how to do this from the CLI, the Config tab would show the necessary commands.

d. Click the FastEthernet0/1 under the Interface heading to configure the FastEthernet0/1 interface.

In the Equivalent IOS Commands, the command interface FastEthernet0/1 is displayed in the Equivalent IOS Commands box.

Step 2: The CLI tab

a. Select the CLI tab to switch to the CLI interface. Notice that the same commands that were in the Equivalent IOS Commands box are listed in the CLI window.

b. At the prompt, enter shutdown.

Central(config-if)# shutdown

Central(config-if)#

%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to administratively down

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down

Central(config-if)#

This command just shuts down the interface down from the command line.

c. Navigate to the Workspace. Notice that the link lights for the connection between PC0 and Switch0 are red. Because the interface on the switch was shut down, the connection is no longer active and shows red.

d. Save and close the activity, then exit Packet Tracer if desired

GUI and CLI Configuration in Packet Tracer

Physical Tab

The Physical tab provides an interface for interacting with the device including powering it on or off or installing different modules, such as a wireless network interface card (NIC).

Config Tab

For intermediate devices such as routers and switches, there are two methods of configuration available. Devices can be configured or investigated via a Config tab (a GUI interface) or a command line interface (CLI).

The Config tab does not provide a real world environment. This tab is a learning tab in Packet Tracer. If you don’t know how to use the command line interface, this tab provides a way to “fill in the blank” to do basic configurations. It will show the equivalent CLI commands that perform the same action if someone was configuring using the CLI tab.

For example, in the figure the user has configured MyRouter as the name of the device. The Equivalent IOS Commands window shows the command that would achieve the same results in the CLI.

CLI Tab

The CLI tab provides access to the CLI interface, which requires knowledge of device configuration. Here, you can practice configuring the device at the command line. CLI configuration is a necessary skill for more advanced networking implementations.

Note: Any commands that were entered from the Config tab are also shown here in the CLI tab.

Desktop Tab

For some of the end devices, such as PCs and laptops, Packet Tracer provides a desktop interface that gives you access to IP configuration, wireless configuration, a command prompt, a web browser, and much more.

Services Tab

If you are configuring a server, the server has all of the functions of a host with the addition of one more tab, the Services tab. This tab allows a server to be configured as a web server, a DHCP server, a DNS server, or various other servers visible in the graphic.
