Controller Area Network or CAN protocol is a method of communication between various electronic devices like engine management systems, active suspension, ABS, gear control, lighting control, air conditioning, airbags, central locking etc embedded in an automobile.CAN initially developed for in-vehicle networking of automobiles has expanded its applications in various other industries. The application started for luxurious cars is now being used in heavy duty vehicles like trucks, buses, trains and rail vehicles.
Handheld devices like a cell phone, palmtop and laptop were rapidly becoming an integral part of our daily lives. In most cases, these devices do not have compatible data communication interfaces, or, if they do, the interface requires cumbersome cable connections and configuration procedures. Isn’t it absolutely fantastic to connect your PC to share music, data and calendar info without using any wires? Or to wirelessly access phone numbers on your PDA from your cell phone.
What is USB? UNIVERSAL SERIAL BUS What does it do?It connects your laptop or PC to the peripheral devices attached to it.How does it communicate?You attach the device using a cable to PC and communication is initiated within a fraction of seconds. However, what looks easy on our end is a complicated process in the USB system. It may be single step in our stride to attach the device and start working but for the system it’s entirely a different picture. In that fraction of second after the device is attached, it initiates step by step process to make communication possible. It starts right from alerting the PC about the attachment, change in voltages at ports, then addressing the devices, gathering the information, loading the drivers and finally communication. Let’s understand each of these steps in detail to get a crystal clear picture about the working of USB.
SPI protocol has earned a solid role in embedded systems whether it is system on chip processors, both with higher end 32-bit processors such as those using ARM, MIC or Power PC and with other microcontrollers such as the AVR, PIC etc. These chips usually include SPI controllers capable of running in either master or slave mode. In-system programmable AVR controllers can be programmed using an SPI interface.Chip or FPGA based designs sometimes use SPI to communicate.
Bluetooth is defined as layered protocol architecture because each layer supports the layer above and below it. The complete protocol stack consists[[wysiwyg_imageupload::]] of both Bluetooth specific protocols which are clearly defined or developed for Bluetooth like LMP and non-Bluetooth specific that were designed to enable the re-use of existing protocols for various functions. Non-specific protocols can be used with many other platforms like WAP, UDP AND OBEX.
Simple analog communication over the telephone wires to the typical USB cables for data exchange, we surely have come a long way in the field of communication. RS232 was the first milestone reached in this journey. It was a standard for electromechanical typewriters and modems for digital data exchange introduced in 1962 by the Radio Sector of EIA. It made the data exchange more reliable over analog channel. The standard defined voltage levels that made it immune to noise disturbances and reduced the error in data exchange.As the technology was growing many electronic devices were being developed during this time like computers, printers, test instrument etc. There came a time where manufacturers felt the need to exchange information between these electronic devices. For example data exchange between a computer and a printer or two computers. But there was no standard or method to accomplish this task. RS232 was the only available standard at the time which was used for data exchange. So, they thought of adopting this standard in electronic devices for digital data exchange.
The MP3 format is a compression tool to reduce the size of the song of without noticeably affecting the quality of the sound. Every day hundreds and thousands of MP3 file are shared and downloaded.With this format a 32 mega byte song is compressed to about 3MB which allows fast downloads and storage of hundreds of songs on our computers hard disk. It has changed the traditional ways which people used to find, listen and store music.Do you know if we stretch out all the data stored on a single compact disc in the straight line it would be over 4 miles long. Surprised! Ok let’s do the math to understand better. Music in a CD is sampled at 44,100 times per second. The samples are 2 bytes (16 bits) long.

Fujitsu Laboratories Ltd. recently came up with a WAN acceleration technology equipped with an ability to transfer large volumes of data between clouds with speeds scaling up to 40Gbps. It uses Field-Programmable Gate Arrays (FPGAs) as catalysts to complete the process. The measure of connectivity on Wide Area Networking lines between clouds is already ticking up from 1Gbps to 10 Gbps, however, this is not enough. The advent of new technologies like AI and IoT steps up the urgency of high-speed data transference. Clouds overwhelmed with too much data would tend to go unstable if it is not transferred to other clouds with at a higher pace
