The time delay between transmitting and receiving data.

The frequency of errors during data transmission.

The comparison of signal strength to background noise.

Factors related to the message itself, like size and complexity.

Factors related to network complexity and device traffic.

The exchange of data between devices over a transmission medium (e.g., wire or wireless).

The complete setup of devices, hardware, and software needed for data communication.

Turning digital data into an analog signal for transmission.

Turning data into a specific format or code for transmission.

Combining multiple data streams into one for transmission.

The pathway for data transmission, wired or wireless.

Different data types like text, voice, video, that can be transferred.

Essential for modern information exchange and digital communication.

Data can be transmitted in both directions, but only one direction at a time. Like a two-way street, only one car can pass at a time.

Data transmission can occur in both directions simultaneously. Like a highway, traffic flows in both directions without interruption.

Text data is converted into a series of 0s and 1s, known as bits. Each character is represented by a unique bit combination.

Images are composed of tiny squares called pixels. Each pixel is represented by a bit pattern, determining its color and brightness.

Sound and music are represented as continuous waveforms. Unlike text or images, audio data is not discrete but changes continuously over time.

A device connecting multiple network devices, allowing direct communication.

A hub that doesn't amplify or improve signal strength.

A hub that amplifies and cleans signals, improving signal quality.

A passive hub doesn't extend the range of a network, while an active hub can extend it.

Hubs operate at the Data Link Layer (Layer 2) of the OSI model.

Hardware and software elements that make communication and data transfer possible in a network.

Devices that initiate communication on the network.

These devices manage how data travels on the network.

A hardware component that connects a computer to a network, enabling data packet transmission and reception.

NICs can be wired (Ethernet), wireless (Wi-Fi) or Bluetooth.

A unique 48-bit identifier assigned to a NIC by the manufacturer. It's used to recognize the NIC on the network, written in hexadecimal format.

Software-configurable settings like IP address, subnet mask, and default gateway that enable communication with other devices.

Another name for a Network Interface Card (NIC), which connects a computer to a network.

A networking device that connects different networks, allowing them to communicate with each other. It acts as a bridge between networks with different security policies or technologies.

A networking device operating at the Network Layer of the OSI model. It connects multiple networks and forwards data packets based on their IP addresses. It is commonly used for connecting different parts of an organization or even multiple organizations.

Routers offer several advantages, including scalability for connecting large or diverse networks, network segmentation for enhanced security and manageability, and efficient traffic management for optimal performance.

Routers can filter traffic based on specific criteria, perform Network Address Translation (NAT) to hide internal IP addresses, and establish secure Virtual Private Network (VPN) connections.

Routers can filter traffic based on specific criteria, blocking or allowing data packets based on their content, protocols, or source/destination addresses.

A mechanism that translates private IP addresses within a network to public IP addresses for communication with the internet.

A secure connection that creates a private network over a public network, allowing users to access resources remotely and securely.

Data is raw, uninterpreted facts, while information is processed and organized data that provides meaning and context. For example, '100' is data, but '100 degrees Fahrenheit' is information.
