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…

- COMPUTER NETWORKS II, LAB-2-WORKSHEET Basic Cisco Device Commands Objectives 1. Secure a Cisco device using passwords. 2. Enable remote access with Telnet and SSH. 3. 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. Connect the router to the switch using a straight-through cable. Explain to me in a practical way so that I understand what is happeningarrow_forwardip ssh version 2 4.

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. Assume the following Light p type x=0 Figure P6.19 | Figure for Problems 6.19 and 6.21. parameters: μ = 1200 cm²/V-s, μp = 400 cm²/V-s, T = 10-6 s, and 7p = 5 × 10-7 s. Neglecting surface effects, (a) determine the steady-state excess electron and hole concentrations as a function of distance into the semiconductor, and (b) calculate the steady-state electron and hole diffusion current densities as a function of distance into the semiconductor.arrow_forward
