  1. 1. Computer Network and Networking Peripherals Kapil Ramesh Rode DOMSMBA11P006
  2. 2. Definition of Computer Network A computer network or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices pass data to each other along with data connections. History : In the late 1950s, early networks of communicating computers included the military radar system Semi-Automatic Ground Environment (SAGE).
  3. 3. Network Diagram
  4. 4. Multiple network diagram
  5. 5. Networking Peripherals • Router A router is a device that forwards data packets between networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks • Firewall In computing, a firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analyzing the data packets and determining whether they should be allowed through or not, based on a rule set. A firewall establishes a barrier between a trusted, secure internal network and another network (e.g., the Internet) that is not assumed to be secure and trusted.
  6. 6. • Switch A network switch or switching hub is a computer networking device that links network segments or network devices • Systems that used in network Networking Peripherals laptop system Server
