Kerio Connect is the successor of the successfull application Kerio MailServer. Kerio Connect
is a modern multiplatform mailserver which supports variety of communication protocols.
These protocols allow using of any email clients including those which are supported by
mobile devices. The mailserver also allows direct access to mailboxes via a proprietary web
Kerio Connect uses mailboxes to store various data types. Besides email messages, calendars,
notes, contacts and tasks are kept in mailboxes. Calendars and tasks offer also task and
There are many occasions when data need to be transmitted over a voice communication network.
Many people use a computer to connect to their Internet Service Provider via the telephone lines to
transmit and receive data, check their email, surf the Web, etc.
Telephone networks were originally built for human speech, not for computer data and is unsuitable for
digital communication in its raw form.
For example, communicating between two PCs via a telephone line (connected between subscriber's
home and local office, then between local offices, and finally between local office and another
subscriber's home). The telephone line is an analog system. That means it can not be used for
digital transmission. If we try to transmit digital signals over the analog system, our bit rate or
bandwidth will be limited to a minimum. On a 4 kHz analog band limited system we can only
transmit at a maximum rate of roughly 1 kHz. Because a 1 kHz digital signal needs a bandwidth
Connecting to an Oracle Database Problem You want to connect to an Oracle database. Solution You can connect to an Oracle database using either the Oracle .NET data provider or the OLE DB .NET data provider. The sample code contains two event handlers
[ Team LiB ] Recipe 1.1 Connecting to an ODBC Data Source Problem You want to access your data source using an ODBC provider from your .NET application. Solution Use the ODBC .NET data provider to access data exposed through an ODBC driver.
The Campus-RS™ SDI (Serial Data Interfaces) are interface modules that install directly into a
Campus-RS remote or Campus-RS Star concentrator and provide serial data connections to
routers and other network devices. The SDI interface modules include a variety of standard
physical interfaces, including RS-232C, RS-449, RS-530, RS-530A, V.35, and X.21 which can
be configured to operate at n x 56/64 kbps rates up to a maximum of 4.608 Mbps.
The Data-Link layer is the protocol layer in a program that handles the moving of data in and out across a physical link in a network. The Data-Link layer is layer 2 in the Open Systems Interconnect (OSI) model for a set of telecommunication protocols.The Data-Link layer ensures that an initial connection has been set up, divides output data into data frames, and handles the acknowledgements from a receiver that the data arrived successfully. It also ensures that incoming data has been received successfully by analyzing bit patterns at special places in the frames....
This book will introduce you to one of the most important extensions to PHP that are available, starting with PHP version 5.0—the PHP Data Objects, commonly known as PDO.
PHP grew in to a very popular web programming language due to its simplicity and ease of use. One of the key factors of this growing success is the built-in possibility to access many popular relational database management systems (RDBMS), such as MySQL, PostgreSQL, and SQLite, to name just a few.
[ Team LiB ] Recipe 1.7 Connecting to a Named Instance of SQL Server or Microsoft Data Engine (MSDE) Problem You want to connect to a named instance of a SQL Server or Microsoft Data Engine (MSDE). Solution You need to understand what a SQL Server or MSDE named instance is and how to connect to one.

This book starts with an overview of PHP Data Objects (PDO), followed by getting started with PDO. Then it covers error handling, prepared statements, and handling rowsets, before covering advanced uses of PDO and an example of its use in an MVC application. Finally an appendix covers the new object-oriented features of PHP 5. This book will guide you through the data layer abstraction objects in PHP. PHP developers who need to use PDO for data abstraction.
[ Team LiB ] Recipe 1.2 Connecting to a Microsoft Excel Workbook Problem You want to access data stored in a Microsoft Excel workbook. Solution Use the OLE DB Jet provider to create, access, and modify data stored in an Excel workbook. The sample code contains two event handlers:
