  • One of the major functions of the physical layer is to move data in the form of electromagnetic signals across a transmission medium. Whether you are collecting numerical statistics from another computer, sending animated pictures from a design workstation, or causing a bell to ring at a distant control center, you are working with the transmission of data across network connections. Chapter 3 discusses the relationship between data, which are created by a device, and electromagnetic signals, which are transmitted over a medium.

  • Most input/output devices reside the computer case. These devices communicate with what is inside the computer case through cables attached to the case at a connection called a port, sending data and/or instructions to the computer and receiving them from the computer. Most computers have their ports located on the back of the case, but some models put the ports on the front of the case for easy access. The most popular input devices are a keyboard and a mouse, and the most popular output devices are a monitor and a printer. The keyboard is the primary input devices of a computer.

  • Synchronous Mode Synchronous systems negotiate the connection at the data-link level before communication begins Basic synchronous systems will begins. synchronize two clocks before transmission. Asynchronous mode Asynchronous systems do not send separate information to indicate the encoding or clocking information. The receiver must decide the clocking of the signal on it's own. This means that the receiver must decide where to look in the signal stream to find ones and zeroes.

  • The purpose of a preface in our view is rather unashamedly to sell the book—to communicate the message of the book succinctly and either to motivate the reader to explore its content or to leave the reader feeling that just maybe he or she is losing out if the book’s theme does not fire their imagination.

  • WiMAX operates on the same general principles as Wi-Fi — it sends data from one computer to another via radio signals. A computer (either a desktop or a laptop) equipped with WiMAX would receive data from the WiMAX transmitting station, probably using encrypted data keys to prevent unauthorized users from stealing access.

  • In this switching mechanism, a circuit is allocated to every piece of complete information (called a call). This circuit allocation is all the way from the sending to the receiving computer or terminal. It stays in place throughout the duration of the call until the sending (or receiving) side signals that it is not needed any more. In more formal terms, we say that a fixed bandwidth is guaranteed throughout the communication session.

  • This diagram illustrates the Physical layer (Layer 1) of the OSI model. The Physical layer is responsible for the ultimate transmission of data over network communications media. It operates with data in the form of bits that are sent from the Physical layer of the sending (source) device and received at the Physical layer of the destination device. Ethernet cabling, Token Ring network technology and SCSI all function at the Physical layer of the OSI model. Hubs and other repeaters are standard network devices that function at the Physical layer.

  • IN 1995, WHEN I WAS IN MY SECOND YEAR IN COLLEGE, I was introduced to UNIX network programming. In C, you could create sockets to open TCP connections to servers and code the servers that accepted these connections. I remember the excitement I felt the fi rst time I created a TCP server: I could accept connections and receive and send messages on them. If I wanted my server to accept many concurrent connections, the common solution was to use threads, and soon I had created my fi rst multi-threaded TCP server.

  • A virtual private network (VPN) is the extension of a private network that encompasses links across shared or public networks like the Internet. A VPN enables you to send data between two computers across a shared or public internetwork in a manner that emulates the properties of a point-to-point private link. The act of configuring and creating a virtual private network is known as virtual private networking.

  • We’ve installed and set up two software programs: the Apache web server with PHP , and the MySQL database server . If you followed my recommendation, you would have set them up using an all-in-one package like XAMPP or MAMP , but don’t let that diminish your sense of accomplishment! As I explained in that chapter , PHP is a server-side scripting language that lets you insert instructions into your web pages that your web server software (in most cases, Apache) will execute before it sends those pages to browsers that request them.
