Block 3 Section 2 Part 1

Identify the amount of data each host can handle, the destination point for each packet

Network device that provides access outside LAN or broadcast domain

The four types of Physical Topologies

What are the three types of Networking Addresses

7 layer reference model that describes how the information moves from one computer to another computer on a network

Develops, Describes, Updates and Maintains the internet

Inter-networking device that connects networks and separates broadcast domains

Host that provides services and informations to other hosts on a network

Network intermediate device utilized to connect end devices while moving and managing the data within a network

Network composed itself of different physical topologies to achieve full network connectivity

Address that serves as a logical pointer to a node on a network

Helps devices determine the network ID and host ID prefixes of their IPv4 address

Focuses on mediums themselves and hardware used to move bits across these medium from one point to another.

Responsible for connecting data back and forth to meet signal encoding specifications of the medium

Focuses on Long term research reguarding the internet

Extremely thin cylindrical glass core, surrounded by a concentric layer of glass called cladding

Distortion and or weakening of a signal as it traverses the media

Proved a level of security through proper encryption and decryption of all data

Referred to as physical hardware address and is a coded address that uniquely identifies specific nodes within a network

Separated portion within the network and can share the same default gateway and be part of the same broadcast domain

Refers to anything that can severely affect the quality of signal encoding

Private IPv4 address used for testing the internal network interfaces on a device

The way devices find each other across networks

Connection point, redistribution point, or communication end point that can receive an address within a network

Carry data in the form of modulated light beams

Routing between networks and fragmenting. Encapsulates data into PDUs called packets

Much higher frequencies than that on a radio, ranging between 11GHz and 14GHz

Connect using radio waves or infrared waves without a physical medium(cable)

The two types of network topologies

Initializing and terminating communications while allowing identification and recognition of users.

Allows the user to interface with the network; the layer the user can see

128 bit hexadecimal address divided into eight 16- bit groups called hextets separated by colons

Houses multiple protocols which OS's, network operations systems and applications use to communicate with each other net

Places of control of network resources on a dedicated-server

Transmission intended for all nodes on a network

Improve signal quality and transfer speed support. Speeds up to 2.5Gps

Utilized modulated radio bands include HF, VHF and UFH

Packaging one message format inside another message format in a sequence

Devices to share the same abilities to use resources available on the network

Binary platform of an IPv4 address that identifies a unique IPv4 where the host resides in

Share the same central connecting code

Two or more devices connected together to share data

Network device that can connect, filter, and forward data traffic from one network segment to another

Refers to mediums composed of conductive material, such as metal

Prevent a surprise technological attack against the United States

The data will go to all nodes on the network

End device that can connect to a network and offer users services and applications that help share and obtain resources

Network that interconnects users with computer resources in a geographic area such as college or military installation

The data will move from one node to the next

Consists of pairs of insulated wires twisted together and intertwined together to exchange signal quality

Relies on transmitting towers within line of sight with each other

Relay data for the network

Contains all encapsulated data from the upper layers

Host that request and obtains information from a server

In order for networks to maintain structure rigidity and scalability different levels of connectivity need to take place

Central conductive core to encode the signal, an initial layer of insulation to protect the core

Breaks the connection between the source and the receiver and acts as an intermediary between the hosts

An area of a network where devices compete for access to the transmission medium

Occurs when one wire induces a voltage across another wire through electromagnetic induction

Sending files to/from hosts

Provides computing resources over networks such as the internet

High speed network limited in geographical scope

The Two Basic Logical Topologies

32 bit address divided into four 8 bit octets separated by a dot

Connection point that interconnects a network node with the actual medium

The form that data takes as it progresses through the encapsulation and transmission

Spans a large geographic area such as a state, province, or country

Automatically manages IP address ; it can also assign these IP address to connecting hosts

Provides access to print devices and manages the information sent by users to networked printer

Used for Sending mail

Refers to media that carries electromagnetic signals that represent binary digits of data using radio/micro waves

Converts analog signals into digital signals and vise verse through the process of modulation and de-modulation

Total number of physically transferred bits in one second over a communication link, measured in bps

Used by a device that lost network connection

Identifies the packet characteristics

Type of disturbance that typically generates from powered devices or radio transmissions in proximity to your medium

Contains information about the type of media used and encoding for the media and also contains MAC address

Improved support for faster speed. Up to 1Gps

Responsible for creating reference standards for routing protocols

How data flows through a physical network

Logical part or division of a network where devices can reach another broadcast without the need of a routing device

Unique binary portion of an IPv4 address that's is specific to each device (host) on a network

Utilize linked networks with satellites orbiting the earth

Operating System oriented towards networking environments

The actual physical communication channel used for the transmission in the network

Transmission intended for only one node

component that serves as a basic central connecting unit point that extends the medium by repeating a signal

Responsible for data flow control, segmentation and error recovery

The process of dividing data into smaller pieces in a sequence

Acts as a remote disk drives functioning as a high-speed central computer

Transmission intended for more than one node

Controlling access to the medium and encoding the medium's signals. Encapsulates data from the upper layers into PDUs

Links names to IP address and vice versa. You can access a website on the internet by typing its IP address

A compilation of protocols that allow communication between devices and networks. Standard for InterNetwork connectivity

Focuses on setting standards for LAN Topologies, Mediums, and Network Access Methods

Focuses on data flow control, segmentation and error recovery. Data encapsulate into PDUs called segments
