Chapter 6, Problem 2Q
Explanation of Solution
Differences between the traditional approach and building block approach to network design:
| Traditional approach | Building block approach |
| It uses structured approach for the network analysis and design. | It uses simple predefined building components to build the network. |
| It change the network design based on the needs of the organization and technology. | It does not change the design based on the needs of the organization and technology... |

Please answer the scenario of the JAVA OOP Programming Assignment 1 below:
Scenario: You have been hired by TechCo to create and manage their employee training portal. Your first task is to develop a program that will create and track different training sessions in the portal. Each training session has the following properties: • A session ID (e.g., "TECH101", "TECH205") • A session title (e.g., "Machine learning", "Advanced Java Programming") • A total duration in hours (e.g., 5.0, 8.0) • Current number of participants (e.g., 25) Each session must have at least a session ID and a total duration and must met the following requirements: • The maximum participant for each session is 30. • The total duration of a session must not exceed 10 hours. • The current number of participants should never exceed the maximum number of participants. Design an object-oriented solution to create a data definition class(DDC) and an implementation class for the session object. In the DDC, a session…

Create users with different privilege levels. 4. Use custom privilege levels to limit user commands. 5. Learn how to reboot a Cisco device. Part 1: Introduction to Basic Cisco Commands Cisco devices allow network administrators to control access and security using the Command-Line Interface (CLI). • Console Password Protection: Secures physical device access. Telnet & SSH: Enable remote login. • User Management: Assign different access levels to users. • Custom Privilege Levels: Restrict users to specific commands.. Part 2: Topology Devices: • 1 Cisco Router • 1 Cisco Switch 1 PC (for configuration) Connections: • • Connect the PC to the router using a console cable.

The applied electric field is zero. A light source is incident on the end of the semiconductor as shown in Figure P6.19. The steady-state concentration of excess carriers generated at x = 0 is 8p(0) = Sn(0) = 2 x 104 cm³.
