Networks connect computers and devices to allow sharing of resources and communication. There are different types of networks including local area networks (LANs) that connect devices within a small area like a home or office, and wide area networks (WANs) that connect multiple LANs across large distances using technologies like the Internet. Common physical network components include computers, switches, routers and cabling. Logical network topologies determine how devices communicate and include bus, star, ring and mesh configurations. Common protocols like TCP/IP and Ethernet are used to enable communication between networked devices.

This document provides an overview of the components and certification requirements for an IT technician. It discusses that an IT technician installs, maintains, and repairs computers and requires training in areas like operating systems, networking, and security. Industry certification like CompTIA A+ or European Certification of Informatics Professional help technicians prove their skills. The document then details the typical components inside a personal computer like the motherboard, CPU, memory, storage drives, ports, and power supply.
This document contains source code for a student information web application with pages for login, new admission, modifying records, and deleting records. The code uses ADO.NET to connect to a SQL Server database and perform CRUD operations like selecting, inserting, updating, and deleting student records based on inputs from text boxes on the different pages. Connections are established to a local SQL Server Express database file and queries use parameterized queries to prevent SQL injection attacks.

This document contains source code for an online banking system with pages for registration, login, deposit, withdrawal, and fund transfer. The registration page inserts user details into a database table. The login page authenticates users by counting rows matching the username and password and redirecting to other pages. The deposit, withdrawal, and fund transfer pages update customer balances in the database table by adding, subtracting, or transferring amounts between accounts.
This document contains code for several pages of an online shopping website:
- The MasterPage handles navigation between pages through image button clicks.
- The Registration page inserts user registration details into a database table upon button click.
- The Login page authenticates users by checking the username and password against the registration table and directs to the product page or displays an error.
- The Product page adds selected products to the cart table in the database when image buttons are clicked and displays success messages.
This code uses Microsoft Office interop to programmatically interact with Excel from a .NET application. It creates a new Excel workbook and worksheet, populates the worksheet with values or strings in a 5x5 range, then displays the workbook. It also includes code to read the values of a range into an array and display the array values in a message box.
This document contains Microsoft Word source code that generates a Word document programmatically. The code adds headings, paragraphs of text, tables with multiple rows and columns, page breaks, and embeds a line chart. It demonstrates how to programmatically format text, insert elements, size objects, and more using the Word object model from within a .NET application.
This code defines a drawing application that allows users to draw various shapes and lines on a picture box. It imports drawing-related namespaces and defines a pen and graphics object. Buttons trigger handlers to draw lines, ellipses, rectangles, arcs, pies, polygons, beziers, and clear the picture box using the graphics object.
This document contains the source code for a basic calculator application. It defines variables to store calculation values and buttons for numbers and operations. Methods handle button clicks to perform calculations by evaluating values, operators, and results and updating the display. The code allows users to enter values, select operators, and see calculation results displayed.
