Components in a PC that determines speed are: RAM, Processor, and Hard Drive. In rare cases, the Motherboard.

The term you're looking for is EULA or End User License Agreement, it tells how the program can and cannot be used by the user.

RY is abbreviated as "Rajamanya". It addresses the Bridegroom as KING!

Central Processing Unit(CPU)

This varies wildly from processor to processor, and dependant on the actual amount of the computer you're measuring!

CPUs are very complex, and as such, they tend to execute highly specified, complex 32-bit or 64-bit code (and some 128-bit special operations) at a rather slow pace. They're very powerful, due to multithreading and multitasking capabilities. But their overall raw firepower is relatively low.

The average Intel Core i750 can push 7 GFlops maximum without overclocking. The Intel Core2Quad 6.9 GFlops. The AMD Phenom II X4 can push 7.5 GFlops.

Phenom II X3 can push 4.5 GFlops.

Phenom II X2 at 3.3 GFlops. Core2Dup E8200 at 2.9 GFlops.

Celeron M 540 at 0.9 GFlops and Pentium4 at 0.74 GFlops.

(Results from MaxxPi^2)

However other components, such as the GPU, can be much faster. This is because their calculations are simpler and require less degree of accuracy and floating point precision.

An nVidia GeForce 8800GS can pull 264 GFlops, and a GeForce 9800GT clocks in at 336 GFlops.

(Any cards before the 8k series did not have 32-bit floating point precision and thus couldn't be measured in flops)

An ATI HD 2400 series is 56 GFlops. 3400 series is 64 GFlops. A 3690 is 428.8 GFlops and 3870 is 496 GFlops. 4890 is 1360 GFLops (1.36 TFlops)

(Cards before the HD 2400 series didn't have floating point precision, except the 9800 series which sorta did.. kinda)

However, FlOPs are not the best measurement of true speed, only raw execution rate. Actual processor speed is dependant on many other factors such as response time, number of pipelines, pipeline length, cache size, cache latency, cache associativity, instruction sets, register size, number of registers, and more. And as such, Flops should NOT be used as a measurement of CPU performance except when comparing two similar processors (such as identical architecture, like AMD vs. Intel x86 with equal cores)

Ultimately, in CPUs alone, it can range from 0.25 GFlops to 7.5 GFlops in the average consumer computer, and up to 20 GFlops for x86 servers [12-core].

GPUs can vary to as much as 2.5 TFlops or more, and changing weekly, or as little as 10 GFlops.

Total, you can expect a PC, all in all, to be capable of 2 to 2600 GFlops in a modern computer, based on hardware configuration. [Ultra-efficiency systems like 533 MHz VIA systems with onboard Unichrome graphics would get maybe 2 GFlops tops, due to their ultra-low power design)

Project Plan

8086 is a 16- bit microprocessor.

It has 20-bit address bus.

It has 14 16-bit registers.

It has multiplexed address and data bus.

It provides 33% duty cycle.

8086 supports multiprogramming.

It is designed to operate in two modes, i.e. min and max.

you can download the simulation program(for running your programs on your computer) at -

It's a power supply with a positive and negative voltage, where one of the voltages tracks the other. For example: the negative voltage tracks the positive. If you regulate the positive to 15v, the negative is going to be -15v. This allows very precise symmetric power.

100 amps to a 3 phase load. Power = 100A x Voltage x 1.73 ((line to line voltage)(1.73=SQRT(3)).

173 amps to each of 3 single phase (line to line) loads. Power = 173A x Voltage (line to line voltage).

or... 100 amps to each of 3 single phase (line to neutral) load. Power = 300A x Voltage (line to neutral voltage).

Example:

- 3 phase, 480v, 100amp to a 3 phase heater. 100A x 480V x 1.73 = 83040 watts.

- 3 single phase 480v (L-L voltage) heaters, 100amp. 173A x 480V = 83040 watts.

- 3 single phase 277v (L-N voltage) heaters, 100amp. 300A x 277V = 83100 watts.

1. This means that transmit and receive pairs are internally swapped to maintain proper signal alignment of the TX and RX wire pairs

For example, someone using windows XP may require some strong parental control facilities and so purchasing windows vista or windows 7 witch have these would be a strong option

The main components are:

The Central Processing Unit (CPU), which does the actual computing (calculating). Information is processed there.

The Internal (RAM) Memory, in which programs that are running and documents that are being used are stored.

The Hard Drive, where programs and documents are stored permanently, for a longer time.

The Motherboard, who create internally links between all physical components of the computer. It regulates the flow of information inside the computer.

Optionally, a Floppy, CD or DVD drive.

An assortment of cards (all optional):

The graphics card, which creates the image you see on screen.

The sound card, which creates the sound you hear.

The network card, with which you connect to the Internet.

There are also the devices outside of the computer:

Keyboard

Mouse

Monitor

Speakers

Printer

A computer is a miniaturized information highway.

All devices in the computer sends information back and forth.

Memory controller, Harddiskcontroller, North/South Bridge, Soundcard, Networkcard, USB controller, Firewirecontroller, Modem controller, Screen card/Graphic card.

I am sure you can think of more.

It depends on what you want them to do. If you simply want to network two computers only, this is done with a cross-over cable.

GRAPHICS HARDWARE TECHNOLOGY

Computers have been getting progressively more inexpensive and it has become household article in these days. In early days the high cost of the hardware for computer graphics remained the stumbling block, which prevented their widespread use. The microelectronics revolution and the subsequent reduction in the price of the digital hardware have completely changed the situation to the extent that it is now realistic to expect that all computers with graphic display hardware capability will be making extensive use of computer graphics. The announcement of the IBM personal computer using 16-bit Intel 8088 microprocessor on August 12, 1981, can be regarded as a historic event, which had a profound effect in the world of computers.

These computers significantly improved the state of display technology in the world of personal computers. The first IBM PC used Intel 8088 microprocessor, which was capable of addressing 1 Mega bytes in the address space and processing 16 bits internally. Two display adapters could reside in the address space: the Monochrome Display Adapter (MDA) and Color Graphics Adapter (CGA). While the MDA could display 25 rows of 80 column text, the CGA could display graphics as well as text. Several graphics modes were made available, including four-color graphics at a low resolution of 320 X 200 pixels and two

medium resolution color graphics at 640 X 200 pixels. Since then, the 720 X 348 resolution of the Hercules Graphics Card (HGC) and 640 X 350 resolution of the Extended Graphics Adapter (EGA) have become common. In 1984, IBM released a Personal Graphics Controller (PGC) with resolution of 640 X 480 and with 256 simultaneous colors selectable from a palette of 4096. The next major change in PC display technology was announced by Apple Company in 1984, in which it has introduced the Macintosh PC. It was the first PC that does not include a text-based display but provided only a graphic display. The application Programs developed for the Macintosh advocated a WYSIWYG (What You See Is What You Get) style of interface. This concept has become a basic requirement in the area of desktop publishing (DTP). Later in 1987, IBM announced different models of their new PC's (models 30, 50, 60 and 80). In these models one of the protected mode screen groups provided a graphics based windowing system. IBM named it as Presentation Manager while Microsoft named it as Window Presentation Manager. Applications that use graphics can be written for the presentation manager and take advantage of the built-in graphics and dialogue box. The IBM PS/2 line of products introduced the following three new video standards l Multi Color graphics Array (MCGA) l Video Graphic Array (VGA) l 8514/A, a high resolution add-on board The PowerPC's from IBM, Apple and other vendors created a new standard for DTP computers. Graphic User Interface (GUI) like a Microsoft Windows 3.x choke a video adapter sitting on an 8-MHz, 16-bit ISA (industry Standard Architecture) expansion bus. ISA bus is now a bottleneck when it is mated with a 100 MHz Pentium processor. Local Bus Technology breaks the bottleneck by getting peripherals like video controllers up to clock speed. This allows the video controller to gain access to the CPU's 32 bit bus running on full clock speed, e.g. on a 33-MHz, 486 local bus PC a video controller could match the 33 MHz clock speed of the processor. Nevertheless, the video performance is enhanced to 15 times as compared with a standard VGA adapter. Two local bus standards are: VL-Bus, a standard proposed by VESA (Video Electronic Standard Association) Committee and PCI (Peripherals Component Interconnect) a brain child of Intel Corp. EISA (Extended Industry Standard Architecture) and MCA (IBM's Micro Channel Architecture) are similarly limited regarding the rate at which peripherals on the expansion bus can operate. A number of devices like LAN cards, Fax/Modem, CD-Rom interfaces, stereo sound Cards, and Multimedia video support are put in expansion slots to add functionality to personal computers. The user find it difficult to handle the complexities of IRQs, DIP switches, jumpers, and drivers. Apple has Plug and Play (PnP) as standard since 1987 to keep users free from configuration problems. PnP as proposed by Microsoft and Intel will make PCs easy to set up and configure, ease the task of installing new hardware and software, and ability to change configurations set up dynamically on a configuration event. Video/Graphic processing can be made faster in two ways: by using graphic co-processor and a graphic Accelerator. The graphic co-processor boosts video performance by assuming tasks normally handled by the CPU. An accelerator takes control of a graphic task otherwise performed by the CPU but it is not programmable. It is a fixed function processor and which carries out specific tasks hard-coded into the chip. The video adapters and monitors use analog signals and could generate 64 values for each of the primary colors RED, GREEN, and BLUE. The result is that these systems can present 256 colors simultaneously on the screen from a palette on 262144 colors. To provide visual interface, additional processing capability is to be provided to the existing CPU. The solution is to provide dedicated graphic processor. This helps in managing the screen faster with an equivalent software algorithm executed on the CPU and certain amount of parallelism can be achieved for completing the graphic command. Several manufacturers of personal computers use a proprietary graphic processor. For example, Intel 82786 is essentially a line drawing processor; Texas Instruments

43010 is a high performance general-purpose processor.

· What can happen if your hardware and computer cables are not maintenance?

because all the files that you deleted arent really gone and off your computer until you "empty" the recycle bin. when you delete something its not gone until you empty the recycle bin incase you decided you want it back or need the file....

I think a typing noise.

Usually the sound of the cooling fans. (whirring)

For a god quality PC power supply;

120mV on the 12V rail

50mV on the 5V and 3.3V rails

Neither. They use a video port, VGA, DVI, HDMI or Displayport.

Yes you can.
