Jacob Rusgrove Week 6 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 each other by allowing information to flow between units and devices. Address lines show the source and end-point of the data on the data lines. Control lines are used in starting the bus protocol. Normally there are lines …show more content…
These rules are also known as bus protocols. The design of a bus system contains several pro’s and con’s related to the size of the data bus, data transfer size, bus protocols, and clocking. Bus systems are categorized as asynchronous and synchronous buses depending on whether the bus communications are controlled by a clock. There are parallel and serial buses depending on whether the data bits are sent on parallel wires or multiplexed onto one single wire. When controlling communications of multiple devices are outlined on defined procedures. Arbitration structures are essential in the control of the bus communications in the presence of multiple devices. In a synchronous bus, the bus system processes are synchronized by way of a clock signal. The bus system clock is provided from the computer system clock, even though it is usually slower than the master clock. Just as an example, 0.6GHz bus systems are used in computer systems with a processor clock of over 5GHz (Matthew, 2004). Bus systems are usually slower than processors. The reason is because memory access times are generally longer than clock cycles of the processor. A bus transaction sometimes takes many clock …show more content…
Handshaking is done to conduct communication of data between the sender and the receiver. In an asynchronous read operation, the bus system master will set the address and control signals on the bus system. It then declares a synchronization signal. The synchronization signal from the master sets the slave to get synchronized. The reason for this is so that when it has accessed the data, it declares its own synchronization signal. The slave's synchronization signal addresses the processor that there is legal data on the bus, and then it reads the data. This mode of synchronization is known as a full handshake. A parallel bus system is a bus system that transfers several data bits at the same time. This bus system requires wide buses because large chunks of data need to be transferred faster. Parallel buses usually have 8, 16, 32 or 64 data lines. A parallel bus system includes: ISA, PCI, VESA, and EISA buses. (Mueller, S. & Zacker, C. 1988). A serial bus system uses the same line to transfer different data bits of the same byte/word. Usually they have only one data line and the bits will flow one after the other, as a packet. An examples of series bus systems are The Universal Standard Bus (USB) and IEEE 1394 bus architecture. Parallel bus systems are more expensive than series bus systems, although, parallel bus systems have a much higher
The moral philosophy best describes my personal decision making is virtue ethics (Ferrell, Fraedrich, & Ferrell, 2013). It best description of me as virtual ethics having exceptional moral character (Ferrell, Fraedrich, & Ferrell, 2013). My character displays honesty, integrity, and helpfulness (Ferrell, Fraedrich, & Ferrell, 2013). For example, a friend attempted to commit suicide as a result of a wife asking for a divorce through email (Ferrell, Fraedrich, & Ferrell, 2013). However, while working I received a phone call from him stating his desire not to live anymore (Ferrell, Fraedrich, & Ferrell, 2013). Meanwhile, I called his son to ensure that he wasn’t alone however, his son drove to the house and found his father sitting and with a

From 2011 and onward, my family had fallen into bankruptcy for paying out of pocket for my older brother’s medical expenses and surgery costs due to his diagnosis of heart failure. In 2013, when I took the standardized ACT exam two times, I scored both times an 18 which was below my university’s 2014 entering freshmen class’s composite score average of 24.5 (copy of score report is attached). Furthermore, upon taking the LSAT two times with over four months of self-studying for the September exam, I scored first a 141, and a 140 on my last attempt. When taking both examinations, I have not been able to afford tutoring pertaining to the exams or a preparation course. Although I have worked numerous jobs during the past few years in college,
1.“If, for example, students were not ultimately rewarded for spending their early adulthoods pursuing undergraduate, graduate, and professional degrees, or if the hardest-working and most productive workers were paid the same as the median worker, then citizens would have little incentive to develop expertise, to exert effort, or to excel in their work.”
This means that the punishment will take place in jails. Another key provision of AB 109
America is dub the land of opportunities and hope by all that look from the outside of the fence in. The shining image of greatness America portrays gives the sense that you can accomplish anything when within its diverse borders. I’m Māori Johnson, and I’m a naturalized citizen of the United States of America from Jordan. Naturalization is defined by the U.S Citizenship and Immigration Service (2013) as the process by which U.S citizenship is granted to a foreign citizen. It’s a rigorous thing to accomplish which consist of first applying for citizenship, if accepted you then go through a written test and exam, probably most natural born citizens couldn’t pass. After you’re accepted life isn’t the easiest to begin. I’ve had to leave behind my job in my former country to pursue my new life here. I am pursing a master’s degree in communications from Texas State University to better my opportunities here. However, I’m working at a local H-E-B while I attempt to pursue a career in my area of expertise while attending school. I’ve expected to have a hard time adjusting in that aspect but I’m enjoying my time here. (Question 1)
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 the data as quickly as it arrives. This is done by the "a synch" data requiring one extra bit worth of time to announce the new byte's beginning and once extra bit worth of time at the end. This is what is known as the "start" and "stop" bits. This means that a 2400 baud modem could transfer only 240 bytes of data per second. Each byte would require a minimum of 10-bit times. This was once called "start-stop" communication, but asynchronous (a sync, for short) is the name (Gilbert, 1995).
Universal Serial Bus is also being used to connect different peripheral devices to your personal computer like the keyboards, printers, digital cameras, media players, internal hard drives and flash drives. It is also the reason it became a standard mode of connectivity. First it was designed just for personal computers but as time passed it has been an option for devices like...
It just doesn't get much simpler than the physical bus topology when it comes to connecting nodes on a Local Area Network (LAN). The most common implementation of a linear bus topology is IEEE 802.3 Ethernet. All devices in a bus topology are connected to a single cable called the bus, backbone, or ether. The transmission medium has a physical beginning and an end. All connections must be terminated with a resistor to keep data transmissions from being mistaken as network traffic. The terminating resistor must match the impedance of the cable.
throughput by transmitting independent data streams on the different transmit branches simultaneously and at the same carrier frequency.
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.
The I2C consist of two active wires i.e. SDA and SCL. Both of these wires support bi-directional communication. Every device, which is hooked to the bus, has its own unique address. Each of these chips can act as sender and/or receiver depending upon its functionality. The I2C bus is a multi-master bus. This means that more than one IC capable of initiating a data transfer can be connected to it. According to the I2C protocol specification, the IC that initiates a data transfer on the bus is considered the Bus Master.
A bus is simply a circuit that connects one part of the motherboard to another. The more data a bus can handle at one time, the faster it allows information to travel. The speed of the bus, measured in megahertz (MHz), refers to how much data can move across the bus simultaneously. Bus speed usually refers to the speed of the front side bus (FSB), which connects the CPU to the northbridge. FSB speeds can range from 66 MHz to over 800 MHz. Since the CPU reaches the memory controller though the northbridge, FSB speed can dramatically affect a computer's performance. The faster a computer's bus speed, the faster it will operate -- to a point. A fast bus speed cannot make up for a slow processor or chipset. Here are some buses I will cover is this report:
Synchronous Transmission: The synchronous signaling methods use 2 different signals. A pulse on one signal indicates when another bit of information is ready on the other signal. This is high speed data communication.
Bus topology refers to a local area network (LAN) arrangement where each node or device is connected to a main cable or link called a bus. A bus network is simple yet very reliable. Since nodes themselves are not relied upon for communication, the failure of a single node is not problematic for the rest of the network. For a major issue to occur, there must be a problem with the bus itself.
