Bluetooth is a short-range wireless technology developed for exchanging data over short distances, primarily designed to support simple wireless networking of devices and peripherals. It uses radio waves to transmit data up to around 30 feet and creates small networks (piconets) of up to 8 devices connected to a central device. While Bluetooth uses the same 2.4GHz frequency range as WiFi, it has slower speeds, shorter range, and supports fewer connected devices, making it better suited for uses like connecting phones and wireless controllers rather than replacing WiFi. Future devices are expected to increasingly incorporate Bluetooth connectivity.

Fundamentals
The document discusses the fundamentals of computer systems, including definitions, components, and how they work together. It defines a computer as an electronic device that accepts input, processes it, and provides output. The key components are the input and output units, memory unit, CPU (consisting of the ALU and control unit), and secondary storage. The input and output units send and receive data, the memory unit temporarily stores programs and data, the CPU performs arithmetic/logical operations and coordinates tasks, and secondary storage provides long-term storage. Together these components work to accept user input, process the data, and provide the results.
Data type
The document discusses fundamental data types in C including integer, floating point, character, and void types. It describes how variables must be declared before use and explains basic type modifiers like short, long, and unsigned. The summary also covers integer storage sizes and ranges, floating point precision and representation, and type conversions in C using casts and arithmetic promotion.
Hibernate example1
This document provides an introduction and overview of Hibernate, an object-relational mapping tool for Java. It discusses what ORM is, why it is used, and defines key Hibernate concepts like entities, mapping files, configuration files, and the session factory. It also provides an example of creating a basic Hibernate project with an Employee entity class, mapping file, configuration file, and test case to load an employee object by ID from the database.
Jdbc workflow
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
2 jdbc drivers
A JDBC type 2 driver converts JDBC API calls to database driver native API calls. It has a two-tier architecture and is faster than other drivers but is database dependent. A type 4 driver converts JDBC calls to database native network calls. It is platform independent, lightweight, and portable but requires implementing network protocols. A type 3 driver converts JDBC calls to database independent network calls and supports three-tier architectures and distributed transactions.
3 jdbc api
The document discusses the JDBC API and the basic steps for working with it to access a tabular datastore from a Java application. It covers:
1. The JDBC API provides an abstraction layer for Java programs to access database services via JDBC drivers.
2. The basic steps involve obtaining a database connection, executing SQL statements, and processing the results.
3. Obtaining a connection involves instantiating a Driver object, constructing a JDBC URL to identify the database, and passing this along with authentication properties to the Driver's connect method.
4 jdbc step1
The document discusses obtaining a connection to a database in Java using JDBC. It provides code examples of creating a database connection using the DriverManager class and Oracle's JDBC Thin driver. The code inserts a record into an EMP table for demonstration purposes. Best practices for database connectivity in a Java project are then covered, such as using the DAO pattern to separate data access logic from business logic. This improves testability, reusability and flexibility in switching database types.
Dao example
The document discusses improving the Data Access Object (DAO) design pattern implementation in a project using JDBC for database connectivity. It describes how the current DAO implementation creates a new Driver object on every request, which is inefficient. It recommends using the DriverManager class instead to manage a single Driver instance and create connections. The DriverManager acts as a factory class to centralize the connection creation code and avoid multiple Driver instances, improving performance.
Sessionex1
This document describes an example of using URL rewriting and hidden form fields to maintain client state. The Home page links to a Login page containing a form for a username and password. Submitting the form calls the LoginServlet, which validates the credentials against a database using a UserDAO. If valid, the user is redirected to a personalized page welcoming them by name.
Internal
This document discusses three ways to set internal styles in HTML:
1) Universal styles that apply to all instances of a tag throughout the page. For example, making all <font> tags bold.
2) Styles using identifiers that allow restricting styles to specific elements. An ID is added and referenced in the style sheet.
3) User-defined styles that can customize styles.
The examples demonstrate applying a green color to all <a> links universally and then using IDs to style two <a> links differently. Internal styles only affect the current page.
3. elements
The document discusses HTML elements and their structure. It explains that HTML elements contain a start tag, element content, and end tag. Elements can be nested within other elements. Common elements like <p>, <body>, and <html> are used to demonstrate how elements are structured and nested to form an HTML document. The document also covers empty elements, case sensitivity of tags, and the importance of including closing tags.
2. attributes
Attributes provide additional information about HTML elements. They are specified in name/value pairs within start tags. Attribute names and values are case-insensitive but it is recommended to use lowercase according to W3C standards. Common attributes include class, id, style, and title, and attribute values should always be enclosed in single or double quotes.
1 introduction to html
This document discusses HTML (Hypertext Markup Language), the most widely used language for creating web pages. It describes what HTML is, how it uses markup tags to provide structure and layout for web content. The document also explains how HTML pages are rendered and displayed in web browsers, and provides examples of common HTML tags and elements used to create basic HTML documents.
Headings
This document provides information on HTML headings, horizontal lines, and comments. It explains that headings are defined using tags from <h1> to <h6>, with <h1> being the most important and <h6> the least important. Horizontal lines are created using the <hr> tag to separate content. HTML comments are written using <!-- and --> and are ignored by browsers.
Forms
HTML forms allow users to enter and submit data to a server. The <form> element is used to create an HTML form, which can contain various input elements like text fields, checkboxes, radio buttons, and submit buttons. Common input element types include text, password, radio buttons, checkboxes, and submit buttons. Radio buttons allow a single selection from options, while checkboxes allow zero or more selections. The submit button submits the form data to the action page specified in the form tag.
Css
1. The document provides an overview of CSS (Cascading Style Sheets) and how it can be used to style web pages by applying styles to HTML elements.
2. Styles can be applied inline, via embedded style blocks, or through external style sheets. External style sheets allow controlling styles across entire websites.
3. CSS properties like font, color, size, and other attributes can be set for elements using selectors like element names, classes, IDs to format text. Additional properties control layout aspects like margins, padding, borders.
Views
VIEWs allow users to select subsets of data from one or more tables. A VIEW acts like a virtual table but contains no data itself - it just represents the result set of a SELECT statement. VIEWs provide a layer of security by restricting access to specific rows, columns, or tables. The CREATE VIEW statement is used to define a new VIEW, ALTER VIEW modifies an existing VIEW definition, and DROP VIEW removes a VIEW.
