Communication where information flows in only one direction from the sender to the receiver.

Communication where information flows in both directions, but not simultaneously. The sender sends information, then waits for the receiver to reply.

Communication where information flows in both directions simultaneously. Both sender and receiver can transmit information at the same time.

Data is sent to all devices connected to a network.

Data is sent to a single device connected to a network.

ARP (Address Resolution Protocol) maps IP addresses to physical MAC addresses. This allows devices to find each other on a local network.

TCP (Transmission Control Protocol) is a connection-oriented protocol that provides reliable data transmission. It ensures data arrives in order and without errors. It is often used for applications like web browsing and email.

UDP (User Datagram Protocol) is a connectionless protocol that provides fast but less reliable data transmission. It may result in data loss or out-of-order delivery and is preferred for applications where speed is crucial.

DNS (Domain Name System) translates domain names (like 'google.com') into IP addresses. This makes it easier for users to access websites using human-readable names instead of complex IP addresses.

IP Fragmentation allows large data packets to be split into smaller fragments for transmission over networks with smaller MTU (Maximum Transmission Unit) sizes. These fragments are reassembled at the destination.

The maximum size of the data field in a TCP segment, which is 65,536 bytes (2^16 - 1).

The process of adding header information to a data packet, like an address label.

A smaller unit of data within a TCP connection, containing data and control information.

The field within a TCP segment that holds the actual user data being transmitted.

The possibility that a TCP segment might exceed the maximum permissible size, requiring fragmentation.

The process of dividing a large data packet into smaller packets (fragments) for transmission, then reassembling them at the destination.

The process of associating a particular TCP segment with a specific connection, allowing the receiver to identify the correct data stream.

A logic gate that can be used to construct all other logic gates. Both NAND and NOR gates are universal logic gates.

A circuit where the output is solely determined by the current input values. It doesn't use previous outputs.

A circuit where the output depends on both current inputs and past outputs like memory. It maintains state.

A circuit used to detect if the number of '1's in a data stream is even or odd. Example of a combinational circuit.

A protocol used for unreliable, best-effort data transmission over networks. It's associated with the IPv4 protocol.

A protocol used to translate human-readable domain names (like google.com) to numerical IP addresses.

Pulse Code Modulation (PCM) is a digital encoding method that converts analog signals, like sound waves, into digital data. Think of it as breaking down a continuous signal into small, discrete pieces, like snapping a photo every few milliseconds.

In PCM, the analog signal is sampled at regular intervals, and each sample is converted into a binary code representing the signal's amplitude at that point. This creates a series of binary values that represent the original signal.

The sampling rate determines how often the analog signal is sampled. A higher sampling rate results in a more accurate representation of the original signal and higher fidelity. It captures more detail in the signal.

The quantization level determines the number of bits used to represent each sample. A higher quantization level allows for more precise representation of the amplitude, leading to better audio quality.

PCM is widely used in telecommunications, audio recording, and digital music playback because it offers a reliable way to encode, transmit, and store audio signals in a digital format.

A physical device that amplifies and transmits data signals across a network. It is typically used to extend the reach of a network by boosting signals and increasing communication distances.

A simple network device that connects multiple devices on a network. It acts as a central hub for data transmission, broadcasting data to all connected devices.

Both Repeaters and Hubs are simple devices that do not analyze data content or filter traffic. They work at the physical layer of the network, solely focused on signal amplification and data transmission.

The process of assigning a unique identifier to a network device, allowing it to be individually recognized on the network. This identifier is used to route data specifically to that device.

The process of transmitting data to all devices connected to a network, regardless of the intended recipient. Using the network's broadcast address, data is sent to everyone at once.

The act of sending data to a specific device on a network, ensuring that only the intended recipient receives the information.

A network device that manages network traffic by forwarding data packets based on network addresses and routing rules. It connects multiple networks and ensures smooth data flow.
