  1. CISCO NETWORKING ACADEMY PROGRAM (CNAP) SEMESTER 1/ MODULE 2 Networking Fundamentals

  2. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Objectives • Upon completion of this module, the student will be able to perform tasks related to the following: • Digital Bandwidth • Networking Models

  3. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Intranets & Extranets • Intranets are designed to permit access by users who have access privileges to the internal LAN of the organization. • Extranets refer to applications and services that are Intranet based, and use extended, secure access to external users or enterprises.

  4. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Bandwidth Bandwidth • Bandwidth has been defined as the amount of information that can flow through a network in a given time • In digital systems, the basic unit of bandwidth is bits per second (bps) • In analog systems, bandwidth is measured by how much of the electromagnetic spectrum is occupied by each signal • The basic unit of analog bandwidth is hertz (Hz), or cycles per second Why bandwidth is important? • Bandwidth is limited by physics and technology • Bandwidth is not free • Bandwidth requirements are growing at a rapid rate • Bandwidth is critical to network performance

  5. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Bandwidth Pipe Analogy

  6. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Bandwidth Highway Analogy

  7. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Bandwidth Measurements

  8. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Throughput • Throughput refers to actual measured bandwidth, at a specific time of day • Throughput is less than or equal to bandwidth

  9. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Bandwidth & Throughput

  10. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Network Protocols • A protocol is a formal description of a set of rules and conventions that govern a particular aspect of how devices on a network communicate • Protocols determine the format, timing, sequencing, and error control in data communication • Protocol suites are collections of protocols that enable network communication from one host through the network to another host

  11. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals OSI Model • The Open System Interconnection (OSI) reference model created by ISO • OSI model is divided into 7 layers Away Pizza Sausage Throw Not Do Please

  12. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Physical Layer

  13. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Data Link Layer

  14. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 • Provides connectivity and path selection between two host • Provides Logical address Networking Fundamentals Network Layer

  15. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Transport Layer

  16. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Session Layer

  17. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Presentation Layer

  18. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Application Layer

  19. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals Peer to peer communications • Each layer of the OSI model at the source must communicate with its peer layer at the destination • This form of communication is referred to as peer-to-peer • During this process, the protocols of each layer exchange information, called protocol data units (PDUs)

  20. CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 2 Networking Fundamentals TCP/IP Model • TCP/IP reference model was created by the U.S. Department of Defense (DoD) • This model is divided into 4 layers which are the followings : • Application Layer • Transport Layer • Internet Layer • Network Access Layer
