The document discusses networking in the IT industry, explaining the process of connecting computer systems for resource sharing and detailing types of networks, including LAN, MAN, and WAN. It also highlights various networking devices such as NICs, hubs, switches, and routers, along with their functions and layers in the OSI model. Additionally, the importance of networking is emphasized through centralized management, resource sharing, data security, and remote management capabilities.
Networking and its importance in the IT industry
- 1. NETWORKING AND ITS IMPORTANCE IN THE IT INDUSTRY SOHIT KUMAR
- 2. WHAT IS NETWORKING? NETWORK Networking is a process of connecting two or more computer systems together for the purpose of sharing resources like files, folders, printers, etc.
- 3. TYPES OF NETWORK Wired Networks WIRELESS ROUTER SERVER SWITCH DESKTOP PC
- 4. TYPES OF NETWORK Wireless Networks
- 5. TYPES OF WIRED NETWORK LAN- Local Area Network • Stands for Local Area Network • Can be implemented for a limited (small) area like an office or building • Can n ot exten d beyon d th e boundaries • Connects limited number of nodes • LAN segment length can not be more than 100 meters NETWORKING HUB SERVER
- 6. TYPES OF WIRED NETWORK MAN- Metropolitan Area Network • Stands for Metropolitan Area Network • Covers larger geographical area than LAN • Fast data-transmission speed • Combination of two or more LANs • Enables communication between two or more cities LAN LAYER 2 ETHERNET SWITCHING LAN LAN LAN
- 7. TYPES OF WIRED NETWORK WAN- Wide Area Network • Stands for Wide Area Network • Largest geographical area coverage • No limitation on coverage area • It can be implemented on demand • Internet is an example of WAN • Enables communication between different countries
- 8. WIRELESS NETWORK • WLAN • WMAN • WWAN Refers to any type of computer network that uses wireless (radio waves) for network connections NETWORKING DEVICES • NIC • HUB • Switch • Router
- 9. NETWORKING DEVICES NIC • Stands for Network Interface Controller or Card • Works in physical and network layer in OSI model • NIC is available with Rj45, BNC and fiber ports • It provides a low-level addressing system through the use of MAC addresses • NIC is used to connect a computer to an Ethernet network NIC ETHERNET NETWORK
- 10. NETWORKING DEVICES HUB • A HUB is a networking device • It is used to connect multiple edge devices together • A Hub is available with 4/8/16/24 ports • Works on layer 1 (physical)
- 11. NETWORKING DEVICES Switch • Switch is a networking device • Works on Mac addresse s • Works on data link and network layer • Switch is available with 24/48 Rj45 ports • It connects multiple Ethernet devices together • Maintains CAM table which contains Mac list of connected edge devices ETHERNET SWITCH ETHERNET ETHERNET ETHERNET
- 12. NETWORKING DEVICES Router • The router is an internet working device • It is used to communicate different networks together • The available ports are Serial, Ethernet, Smart Serial, Console, AUX, BRI, etc • It is used in a large network environment • Works on network layer in OSI model • Router is a destination look-up mode device work
- 13. IMPORTANCE OF NETWORKING IN IT INDUSTRY • Centralized management • Resource sharing like files, folders, printers, etc • Centralized Data backup • Data confidentiality and security • Remote management • High availability of data
- 14. IMPORTANCE OF NETWORKING IN IT INDUSTRY Centralized Management • Easy to manage large network Eg: Distribute an IP address and keep a track of distributed IP address • Manage authentication for users and groups • Monitor network through Net Monitoring tools
- 15. IMPORTANCE OF NETWORKING IN IT INDUSTRY Resource Sharing Through a network, all users can access a single resource (file/folder/printer, etc) which has been shared on the network
- 16. IMPORTANCE OF NETWORKING IN IT INDUSTRY Centralized Data Backup Via networking, the Admin can manage centralized data backups and availability of data DATA BACKUP
- 17. IMPORTANCE OF NETWORKING IN IT INDUSTRY Data Confidentiality Security Via networking, the Admin can manage User’s data confidentiality and security. The Admin can also manage data access permissions. DATA
- 18. IMPORTANCE OF NETWORKING IN IT INDUSTRY Remote Management The Admin can troubleshoot User issues via remote connections like 1. Remote desktop connection 2. Remote assistance 3. Team Viewer 4. Remote admin, etc.
