Network- Chapter 01

What is Network?  

Ans : Networking Devices means refers to the process of interconnecting multiple computing devices (like computers, smartphones, and servers) so they can communicate and exchange with each-other data, and share resources with one to another that is called computer networking devices. 

Important of Network 

Networking is important because it:

• Connect the modern digital world
• Supports businesses and educations
• Enables cloud computing
• Helps Cybersecurity operations
• Improves teamwork and communications 

How Network Works?

Which one device sends data, the network transfers that data to another connected device using communication protocols such:  

• TCP/IP
• HTTP
• FTP

Example:  

• Sending email 
• Sharing Files
• Videos Calling
• Accessing websites

Real -Life Example of Network? 

• Office Network - Employees share printers, files and internet. 
• School/College Network: Students online learning systems
• Banking Network : ATMs connect to bank server
• Mobile Network: Smartphones communicate through telecom towers
• Internet : Largest network in the world

 

Components Required in a Network? 

•  Devices: 

• Computer
• Servers
• Smartphones

•  Networking Devices 
• Router 
• Switch
• Hub
• Modern
• Transmission Media
• Ethernet Cable
• Fiber Optic Cable
• Wireless Signals  

Types of Networks:

1. LAN(Local Area Networks): Small area network such as office or home
2. MAN(Metropolitan Area Network): Covers a city or large campus.
3. WAN(Wide Area Network): Large network connecting countries or worldwide locations, so it's biggest hub internet worlds.

Advantages of Networking: 

• Fast Communications
• Resource sharing
• Centralized data management
• Internet sharing
• Remote access

Disadvantages of Networking 

• Security risks 
• Virus and malware
• Setup cost
• Network failure can affect all users

 

Assessment Of Chapter 01: 

Compare LAN & WAN with Reference to Broad Network Categories:  

Ans:  Comparison of LAN and WAN

Category	LAN (Local Area Network)	WAN (Wide Area Network)
Geographical Area	Covers a small area like a home, office, or building	Covers large areas like cities, countries, or continents
Ownership	Typically, privately owned	May be private or public (e.g., managed by ISPs)
Data Transfer Speed	High speed (100 Mbps – 10 Gbps or more)	Relatively slower (due to long-distance communication)
Cost of Setup & Maintenance	Low cost (less cabling, devices are cheaper)	High cost (leased lines, satellites, routers)
Latency	Low latency	Higher latency due to distance and multiple nodes
Devices Used	Switch, Hub, Router, NIC	Router, Modem, Satellite, Leased Line
Security Level	Easier to secure due to controlled access	Harder to secure; needs advanced protocols (e.g., VPN)
Ownership & Management	Managed by an individual or organization	Managed by multiple organizations or ISPs
Example	Network in a school or small business	Internet, Bank networks across regions

Conclusion of this course: 

So, LAN is fast, low cost, and ideal for local connections withing a small area. 

WAN is suitable for connecting remote locations over vast distances, often using the internet or internet or leased telecommunication lines.

Thanks for leaning this course.
