Peripheral Component Interconnect (PCI) Bus Arbiter

It is a communication method for bits traveling to the design location between input, memory, processors, and output devices. The bit also represents the physical lines over which the data is sent. The bus helps to reduce the amount of "lanes" required for communication between the components mentioned above. The bus does this by sending all communications over a single data channel. The speed at which the bus transmits data is measured by frequency (hertz) in cycles based upon transmit and receive time per second. The bus is simply a local highway. Data and address are two types of buses. The address bus provides a specific physical address and carries memory addresses needed for the processor to access in order to read or write data. The data bus pass on the required data coming and going to the processor. There is also a control bus that carries orders and synchronize signals from the control unit in route to the other hardware components. In other words, the control does the directing for information flow and identifies in what way data routing should occur through the

This new generation of cards also moved away from the PCI bus (it was the slot where you plug your graphics card in) to a new Accelerated Graphics Port (AGP) which allowed for the card to access system memory to help with complex operations such as texture-mapping [2,4].

This is a microprocessor that allows the computer to boot up. It also allows data manigment between the operating system.

The Xeon line of processors from Intel are engineered for servers to outperform competitor CPUs. Intel included a full compliment of features that would go entirely unused in a desktop but vital to server performance. In a space with many options, Intel aims for Xeon to be best of type in both benchmark and practice.

19. Some hardware can be added to the computer without having to restart or power down the computer. After a short period of time the device driver automatically loads and the hardware is available to applications and the user. This type of hardware is considered compatible with what type of technology?

Motherboard is centralized computer of the PC that all framework inside the electronic in light of the fact that a few sections are not quite the same as each other like RAM, CPU and framework unit

It keeps all of the parts connected to it through the use of different connections configured through the use of a north and south bridge. Depending on the architecture of the PC, these areas become fairly different. However, the CPU is located always on the north bridge, and is connected through either a land grid array socket or a pin grid array socket, depending on if you have an Intel or AMD CPU. The RAM is also connected through the use of the north bridge. The north bridge generally is to access data fast. The south bridge is where the mass storage is located, along with any I/O for the computer. This includes USB ports, and audio ports or sound cards, and even the video card. This is due to the lesser amount of information that some of the connections need. Obviously, with advancements in recent years, the speeds that the south bridge supports have increased tremendously. For example, a SATA port on the south bridge can transfer

a) The control signal and the address location in the memory chip are verified and registered using the TDI pin, then the first test vector is turned on. The processor will work in the Selected mode.

1. The device layer is responsible for communicating with a specific subsystem’s devices.It is present in every

Some internal components can be directly plugged into the motherboard but others can be connected through motherboard ports. Its purpose is to connect all other components and peripherals to allow the communication between them.

This section gives the details and specification of the hardware on which the system is expected to work.

A bridge is a type of device that enables the connection with other bridge networks that uses the same protocol. Bridge operates at the data link layer which the PDU layer is called as “Frame”. This allows the two or more different networks to communicate to each other and exchange information if the users wish to. They are also known as layer 2 switches as the data link layer is located at the OSI layer 2.

27. You have installed Windows Server 2008 on a new server and want to centralize user logons and security

Switching techniques can be classified based on network characteristics. The main task of switching technique is to establish connection between input and output channel inside the router. Circuit switched networks reserve a physical path before transmitting the data packets, while packet switched networks transmit the packets without reserving the entire path. Packet-switched networks for communications within large multi core systems on-chip are made for enhanced performance, scalability, modularity, and design productivity compared to busses and dedicated signal wires (R. Mutha, 2012).

The PCF8574AN is an 8-bit inter-integrated circuit (I2C) bus input/output (I/O) expander. This chip allows more I/O in the system. The I2C bus is a network which contains a master and slave. For this project the master is the Raspberry Pi and the slave is the I/O expander chip. The two communicate via the data and clock lines. The slave has an additional address so that the master can identify it in the network if there were more slaves.
