Inter IC Communication:- Inter IC Communication bus, often abbreviated as I2C bus, is a multi-master bi directional 2 wire serial bus for Inter IC communication, developed by Philips Semiconductor. The I2C bus consists of only two lines; one is called SDA (Serial Data line) carries the data bits and the other is called SCL (Serial Clock Line) is used as a clock signal. The messages sent over the I2C bus contain addresses to define which device should reply to them. All I2C-bus compatible devices
Data Transmission The purpose of this report is to describe some common data transmission terminology. This paper will discuss various data transmission (communication) protocols and how they are used in data communication. Synchronous and Asynchronous: Asynchronous serial transmission is a technique used in serial RS232 communication. The data is framed by a series of control bits known as the start bit, stop bit(s), parity bits and error checking bits. A transmit clock signal is used to
Assignment Grantham University 9-9-17 A bus is a communication system that connects multiple subsystems within a computer. An average computer system normally consists of several components such as a central processing unit, memory devices, and input/output (I/O) devices. The bus system consists of linking media like wires and connectors, and a bus protocol. Buses can be categorized as serial or parallel and synchronous or asynchronous. The bus lets the different components communicate with
Synchronous and Asynchronous mode: In telecommunication signaling within a network or between networks, synchronous signals are those that occur at the same clock rate when all clocks are based on a single reference clock. Synchronous communication requires that each end of an exchange of communication respond in turn without initiating a new communication. An asynchronous signal is one that is transmitted at a different clock rate than another signal. Asynchronous operation also means that a process
of data communications in terms of the physical interfaces and modes of operation. It will describe the features of data communications equipment in relation to synchronous and asynchronous communication including modems, network terminating units and sending and receiving equipment. Define synchronous and asynchronous Synchronization: The receiver is able to determine when a signal begins to arrive and when it has finished. It must also know the duration of the each signal. Asynchronous Transmission:
INTRODUCTION Bluetooth is a wireless LAN technology designed to connect devices of different functions such as telephones, notebooks, computers (desktop and laptop), cameras, printers, and coffee makers. A Bluetooth LAN is an ad hoc network, which means that the network is formed spontaneously but sometimes it called gadgets and make a network called a piconet. The cable-free, or wireless, technology was initially conceived by Ericson in 1994, when the company began a study to investigate the feasibility
Main reasons to move on Parallel Computing are: Save time: Parallelization take less time to solve a problem as compare to serial computing. Hence, today’s parallel computing becomes more useful to solve problems in less time. Large Problem Solving: Many of the problems are very large or complex and solution of these problems are impractical and impossible to solve on a single
internal or external hardware devices. Before the computer modem, there was the com-port. When an internal modem card is placed inside of a computer, it behaves as a COM2 or COM3 port. It is also possible connect serial mice into one of these ports (Gilbert, 1996). Asynchronous communication is used in the PC COM port. Each byte of data is a separate unit and the computer that is sending the data can pause between any two bytes of the message. However, the receiver of the message may have to catch
for communication between two machines that are previously configured for communication with each other. For example, your Internet server provider may provide you with a SLIP connection so that the provider's server can respond to your requests, pass them on to the Internet, and forward your requested Internet responses back to you. A better service is provided by the Point-to-Point Protocol (PPP). Point-to-Point Protocol is a protocol for communication between two computers using a serial interface
logic controllers (PLC). This section includes a brief history of PLCs, how they work, different programming languages used and some commonly used instructions. Section 2.5 describes various types of signals used in control including digital, analog, serial, fieldbus, and SCADA. 2.2 Refrigeration Process 2.2.1 Background For most of history, ice and snow, packed into cellars insulated with wood or straw, were used for refrigeration. It wasn’t until 1755 that the first artificial refrigeration system
DECISION SUPPORT SYSTEMS: “Decision Support Systems (DSS) are a class of computerized information systems that support decision-making activities. DSS are interactive computer-based systems and subsystems intended to help decision makers use communications technologies, data, documents, knowledge and/or models to successfully complete decision process tasks” Reference: http://dssresources.com/ Decision support systems are the computer information application which collects and analyze data
Alternatives of Network File System Since human beings have used Computers , the request of being rich ,and getting more information quicker than before has increased . Have you ever found yourself rushing from one computer to another in your office or home ,attending to several different jobs at various location? Or do you often find yourself moving files that need printing from a PC that you happen to be working on the PC that is Connected to the printer ? You may have heard a lot about
voice and data communications services, in addition to television programming. After passage of the Act, the cable companies were eager to expand into the new fields of business that had been opened to them, especially the rapidly growing Internet Service Provider (ISP) business. The biggest hurdle facing the cable companies is that cable television systems were designed for one-way traffic, and must be upgraded into modern two-way networks in order to support advanced communications services.
