What is Basic Networking?

The process of connecting two or more computing devices such as PCs, servers, or printers to one another via a common wired or wireless communication means is known as basic networking.

They can communicate using established protocols (rules) like TCP/ IP, share resources (like files and printers), and exchange data thanks to this networked system. Let’s take a look at what “Basic Networking” is!

Key Components of a Network

S.No.	Components	What?
1.	End Devices (Clients & Servers)	These include computers (clients) and data hosts (servers), which are the sources or destinations of data on the network.
2.	Intermediary Devices	These devices, which include switches and routers, link the endpoints and control the data flow throughout the network.
3.	Connection & Interface	This includes the Network Interface Card (NIC) that connects a device to the network, as well as the physical media (cables or wireless signals).
4.	Protocols	These are the guidelines and standards (like TCP/IP) that dictate how devices interact with one another as well as how data is formatted and sent.
5.	Network Operating System (NOS)	This program controls user access, maintains network resources, and offers network security.

Types of Computer Networks

The following types of computer networks:

PAN (Personal Area Network): Uses Bluetooth or other short-range wireless technologies to connect a few personal devices around an individual.
LAN (Local Area Network): Connects gadgets and computers in a small, discrete space, such as a home, workplace, or single building.
WLAN (Wireless Local Area Network): Wi-Fi is a local area network (LAN) that connects devices in a restricted area using radio waves rather than physical connections.
CAN (Campus Area Network): Connects several distinct LANs in a constrained geographic area, like a military installation or university campus.
MAN (Metropolitan Area Network): Usually connects multiple LANs and covers a wider geographic area, such as a city or major town.
WAN (Wide Area Network): Connects networks across large geographic distances, such as states, nations, or the entire world (e.g., the Internet).
SAN (Storage Area Network): A specialized, fast network that gives servers block-level access to dedicated, aggregated storage.
VPN (Virtual Private Network): Allows people to exchange and receive data securely as if they were directly connected by extending a private network over a public network (such as the Internet).

How Does Networking Work?

S.No.	Factors	What?
1.	Data Preparation and Segmentation	The transport layer (such as TCP or UDP) divides the application data into smaller, more manageable pieces called segments.
2.	Packet Creation (Addressing)	The network layer encapsulates each segment with an IP header that contains the source and destination IP addresses to create a packet.
3.	Framing and Physical Prep	The data link layer (such as Ethernet) adds the MAC addresses for local delivery and wraps the packet in a frame header and trailer.
4.	Local Delivery via Switches	Switches use the destination MAC address to deliver the frame to the appropriate local device after it has been sent over physical media.
5.	Inter-Network Routing	A router receives the packet, removes the previous frame, and uses the IP address to identify the next hop if the destination is on a different network.
6.	Transmission Across Networks	Until the packet reaches the ultimate destination network, the router forwards it to the subsequent router over the internetwork (such as the Internet).
7.	Final Delivery and Reassembly	After receiving the frames, the destination host removes the headers, trailers, and wrappers, reassembles the segments into the original data, and then sends it to the application.

Common Networking Devices and Their Roles

The following are some common networking devices and their roles:

● Router: Connects various networks (LANs, WANs, and the Internet) and uses IP addresses to find the optimal route for data packets.

● Switch: Connects several devices to a single Local Area Network (LAN) and uses MAC addresses to send data solely to the designated destination.

● Wireless Access Point (WAP): Enables wireless connections between Wi-Fi devices and wired networks, hence expanding the LAN's reach.

● Modem: Transforms your computer's digital signals into analog signals so they can be sent over phone or cable lines, and vice versa, to connect to your internet service provider.

● Network Interface Card (NIC): A circuit board or chip in a computer, server, etc. that serves as the physical link to the network medium (wireless or cable).

● Firewall: A security system that uses a set of preset security rules to monitor and regulate incoming and outgoing network traffic.

● Repeater: Amplifies and regenerates a network signal to increase its transmission range and stop signal deterioration.

● Hub: A straightforward gadget that links several devices yet broadcasts every incoming data to every other port, resulting in heavy traffic and accidents.

Real-World Applications of Networking

S.No.	Uses	What?
1.	Communication & Collaboration	For both personal and professional purposes, networks enable instantaneous worldwide connection via email, video conferencing, and instant messaging.
2.	Resource Sharing	Within an organization, it enables numerous people to share costly hardware resources like printers, scanners, and huge storage devices at the same time.
3.	Internet Access	Web browsing and information retrieval are made possible via networking, which links local devices to the Internet's Wide Area Network (WAN).
4.	E-Commerce and Banking	Secure networks enable safe, instantaneous processing of banking procedures, financial transactions, and online purchases from any location in the world.
5.	Remote Work and Telecommuting	Employees can access company data and systems from home or remote locations thanks to virtual private networks (VPNs) and secure connections.
6.	Entertainment and Media	Networks provide computers, phones, and televisions with on-demand video content, streaming services, and online games.
7.	Centralized Data Management	To ensure simple backup and access, businesses employ networks to store all important files and programs on centralized servers and data centers.
8.	Healthcare and Telemedicine	Networks provide remote consultations, diagnostics, and surgical support while securely transmitting patient records (EHRs).
9.	Internet of Things (IoT)	It links billions of commonplace physical devices such as cameras, sensors, and smart appliances to the cloud for data sharing and automation.

IP Addressing and Subnetting Basics

IP addressing uses a hierarchical structure to uniquely identify each device on a network (IPv4 uses a 32-bit address, such as 192.168.1.1). The address is logically split into two parts: the Host ID, which is based on a subnet mask, and the Network ID, which identifies the network.

In order to preserve IP addresses and lessen network congestion, subnetting is the act of taking bits from the Host ID part of the IP address to form smaller, easier-to-manage sub-networks.

Network Security Essentials for Beginners

S.No.	Factors	What?
1.	Use Strong, Unique Passwords	Make complicated, lengthy passwords for every device and account, and never use the same ones twice.
2.	Install and Update Antivirus/ Anti-Malware	Use security software to find, stop, and get rid of harmful applications like ransomware and viruses.
3.	Enable a Firewall	To monitor and manage network traffic and prevent unwanted access to and from your network, use a firewall (hardware or software).
4.	Keep Software and Operating Systems Updated (Patching)	Apply security patches and software upgrades on a regular basis to address known vulnerabilities that hackers might exploit.
5.	Secure Your Wi-Fi Network	Use strong encryption (WPA3 or WPA2), alter the default network name (SSID), and modify the router's default password.
6.	Implement Network Segmentation (VLANs)	To stop possible breaches from spreading, logically split a big network into smaller, isolated sections.
7.	Backup Your Data Regularly	To guarantee recovery following an incident, keep safe, verifiable copies of all important data, and frequently use the 3-2-1 rule.
8.	Educate Users on Phishing and Social Engineering	Teach all users to spot dishonest attempts to deceive them into disclosing private information, such as dubious emails or calls.
9.	Disable Unnecessary Services and Ports	To lessen the network's attack surface, disable any network services, protocols, or ports that aren't in use.
