Module 2 Quizlet
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.
Wi-Fi. . .
. . .The 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.
Networking devices. . .
. . .connect other devices, mainly hosts. These devices move and control network traffic. Examples of network devices include hubs, switches, and routers.
The use of logical device naming and addressing conventions that are well documented can. . .
. . .greatly simplify the task of training and network management and can help as well with troubleshooting when problems arise.
Bluetooth. . .
. . .is a low-power, shorter range wireless technology that is intended to replace wired connectivity for accessories such as speakers, headphones, and microphones. It can also be used to connect a smartwatch to a smartphone. Because this technology can be used to transmit both data and voice, it can be used to create small local networks. It is wireless technology that allows devices to communicate over short distances. Multiple devices can be connected at the same time with it.
Near Field Communication (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, it can be used to connect a smartphone and a payment system. It uses electromagnetic fields to transmit data.
As a network grows in size and complexity,. . .
. . .it becomes increasingly important that it is well planned, logically organized, and well documented.
Device names. . .
. . .must be unique and should have a consistent format that conveys meaningful information. (This can help to determine device type, function, location, and sequence number based on the device name.)
Network media. . .
. . .provides connections between hosts and network devices. Network media can be wired, such as copper and fiber optic, or use wireless technologies.
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.
IP addresses must also be. . .
. . .unique to each device.
Documenting the physical connections and devices in your network. . .
. . .will provide you with the information that you need to know when connecting new devices or finding problems with broken connectivity.

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.
Global Positioning System (GPS)
The GPS uses satellites to transmit signals that cover the globe. The smartphone can receive these signals and calculate the phone's location to an accuracy of within 10 meters.
Manual IP Configuration
With it, 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.
what other info do you need to have when troubleshooting network problems? (not physical)
The device names, IP addressing, configuration information, and network designations which are logical pieces of information that may change more frequently than the physical connectivity.
IP address
This identifies the host on the network.
Default gateway
This identifies the networking device that the host uses to access the internet or another remote network.
Subnet mask
This is used to identify the network on which the host is connected.
