Extract of sample "Digital Communication System"

Download file to see previous pages For all of us who stick to internet daily and can’t move ahead without its extended support, it becomes necessary to know the intricacies of the internet. Today the world has come much closer with the advent of the internet and cellular communication systems. The cultural, lingual, technological, political, ethical and intellectual gap is being bridged because of these tools. People from different topographical regions have virtually come very close to each other. The following assignment deals with “internet” as a digital communication system.
The Internet is an interconnection of networks. It isn’t just one network but a multitude of networks connected to each other through wired or wireless signal transmission systems. A very commonly asked question about the internet is: Who runs it? The truth is that there is no centralized management. Instead, it is a collection of thousands of individuals and organizations each of which is run and paid for on its own. Here we can imagine the chaos that can be caused due to improper co-operation amongst bearers and users of the internet! Hence to have proper functioning of the entire system, a set of rules has been defined for communication to take place. This set of rules is known as Transmission Control Protocol/Internet Protocol (TCP/IP). When we send information across the internet, the information first breaks into packets. Our computer sends these packets to the local area network or Internet Service Provider (ISP). The packets then travel through many levels of networks, computers and communication lines before the final destination which could be anywhere in the world. A variety of hardware and array of network layers process these packets. Five of the most important pieces of hardware are:
REPEATERS: The signal travels large distances across networks.  ...Download file to see next pagesRead More

Digital Forensics in the Criminal Justice System undertaken by appropriation of storage drives, tapping or observing information movement or making digital duplicates of information held. Even though hard copy of digital information is not considered as digital information, it is regarded as the initial point for smearing the use of digital evidence in the future (7Safe, n.d.). Therefore, the digital evidence noticed at the scene was a hard drive, 2 CD disks, a thumb drive, a telephone, and 3 system units. There is also a card reader, monitors, and a modem; however, those objects are not that useful. Collection of Digital Evidence Any case of trail process regarding...

Digital System

...Digital System Digital System Part The design of the 8 controller, has been carried out using three D-flip flops have. Figure showing the 8-state controller design using three D flip-flops Since the basic design involves the use of D flip-flops, let's see what the basic D-flip-flop is like and how it functions. A D flip-flop is a latch constructed from an SR latch. It has two additional AND gates, and a NOT gate. There are two ways to input into this flip-flop, one is the data input (D) and the other is the gate (G) or enable (E) input. The above figure shows the figure for D flip-flop, which is used in the design. D flip-flops are also known as a transparent latch...

But now it is used irresistible for data broadcasting. It is due to the telephone companies that T1 exists in this world. Due to the continuous improvements in technology of Digital communication, new communication systems emerged as some of the major today's digital communication systems includes GSM, iDEN, CDMA and others. In general this research paper includes the history of digital communication and T1 and the main...

...colleagues. The world has significantly shrunk since the Internet and augmented computer technology. Moreover, while many computer-savvy citizens believe that computers can help better the economy as well as diminish the barriers of social and racial segregation, there are many factors rotating around the requirements of computer learning and owning which are proving the reverse in our school systems and in personal households. (Ahuja, 2006 155) These factors could be testament to other parts of our culture, such as business, that computers are actually thickening these barriers of separation with various peoples in the world. 2.

Coding Schemes in Optical Fibre, Dicode Pulse Position Modulation, Reed Solomon Code, and FPGA

...of digital transmission of data, baseband transmission is used. This implies that logical signals are sent for low and high levels of light. For low light level the logic signal is 0 and for high level of light the signal is 1. Sometimes a certain density of the transmission is obtained through data coding that can be applied in the process (Goff, 2002, n.d.). A good balance of 0s and 1s are offered by the schemes of line coding as discussed by Senior (2009, p.737). Related to this is the optical power budgeting that has been focused in studies by Senior. For the communication system based on optical fiber, power budgeting is obtained in the same way as it is done in case of other...
