Network Communication

What is Network Communication?

Network Communication is a critical process that allows computers to exchange data and information. This exchange happens over a shared medium, either wired (like Ethernet) or wireless (like Wi-Fi or 5G). The primary use of Network Communication is to facilitate data sharing, collaboration, and connectivity between different computing devices.

Functionality and Features

Network Communication includes multiple protocols, standards, and technologies to enable efficient and reliable data transfer. These include Transmission Control Protocol/Internet Protocol (TCP/IP), User Datagram Protocol (UDP), and others. These protocols ensure data integrity, control data flow, and handle network errors.


The architecture of Network Communication is based on a layered model, most commonly the OSI (Open Systems Interconnection) model. This model separates the communication process into seven layers, each responsible for different functions. These layers are Physical, Data Link, Network, Transport, Session, Presentation, and Application.

Benefits and Use Cases

Network Communication helps businesses streamline their operations, collaborate effectively, and make data-driven decisions. It is indispensable in various fields, from cloud computing and distributed systems to Big Data analytics and IoT (Internet of Things).

Challenges and Limitations

Despite its advantages, Network Communication can pose challenges like network congestion, latency issues, security threats, and hardware failures. It requires regular maintenance and monitoring to ensure optimal performance.

Integration with Data Lakehouse

In a Data Lakehouse environment, Network Communication plays an essential role in data ingestion, processing, and analysis. It facilitates access to disparate data sources, allows distributed data processing, and enables data sharing among different components of the lakehouse.

Security Aspects

Network Communication comes with various security measures, including data encryption, firewalls, intrusion detection systems, and virtual private networks (VPNs). These measures aim to protect the data during transmission and safeguard the network from threats and cyber-attacks.


The performance of Network Communication can be influenced by factors like network topology, bandwidth, latency, and the efficiency of protocols used. With the right practices and tools, Network Communication can support high-volume, high-speed data transfers necessary for real-time analytics and decision making.


What is the role of protocols in Network Communication? Protocols, such as TCP/IP and UDP, define the rules for how data is transmitted over the network. They ensure data integrity and manage network errors.
How does Network Communication support data analytics? Network Communication enables data ingestion from various sources, facilitates distributed data processing, and allows the sharing and display of analytical results, supporting data-driven decision making.
What are the security measures in Network Communication? Security measures include data encryption, use of firewalls and intrusion detection systems, and implementation of virtual private networks (VPNs).


OSI Model: A conceptual model that standardises the functions of a communication system into seven categories or 'layers'.
Data Lakehouse: A modern data architecture that combines the best elements of data lakes and data warehouses for more flexible, efficient data analytics.
TCP/IP: A suite of communication protocols used to interconnect network devices on the internet.
VPN: A virtual private network extends a private network across a public network, enabling users to send and receive data as if their computing devices were directly connected to the private network.
Latency: A measure of time delay experienced in a system, the precise definition of which depends on the system and the time being measured.
