Can you explain server hardware details?

Answer

I'll start with the basics, others should expand as needed.

It is easiest to explain a server by telling how it is different from a client computer.

A server is expected to remain on all the time. Due to this requirement, a true server will have completely redundant hardware. This means all the hardware will come in pairs, and if one piece fails, the other piece will continue working until the first piece is replaced. One notable technique is RAID, which has spilled over into regular computers.

RAID stands for Redundant Array of Independent Disks. In one configuration, all data is written twice, on separate drives. One drive acts as backup to the other. Another configuration that is more complicated involves splitting the data up between different drives, and adding a little extra data that allows all the data to be recreated if one drive should fail. There exist many more RAID configurations than can be brought up here.

RAM: Random Access Memory is used that has error control capabilities built into it. It is also typically redundant if dedicated server hardware is used.

Power supplies, CPUs, and RAM are typically paired, with one ready to completely run the server if the other fails. Also, a greater emphasis is placed on reliability, rather than on speed.

When did the cassette tape become popular?

Because it was hard to listen to lp's while driving down the road, and they sounded better than 8-tracks.

How many pins in ddr1?

240 pins, or actually connections on a DIMM, dual inline module.

How does pendrive works?

Pen drives consist of a small printed circuit board. This circuit board provides a sturdy base for the pen drive's form and also serves as a means to collect information. The microchip within it (the circuit board) is able to extract data with relatively low electrical power. It is based on old EEPROMS technology that allows writing and erasure processes.

When a pen drive is connected to a USB port, it activates. Otherwise, it lies dormant. The USB port gives the pen drive access to information on a specific computer. Because most pen drives are formatted using FAT or FAT 32 File systems, they are compatible with almost any USB host/port on a computer.

Data is read, transmitted or rewritten from a pen drive to a computer (or vice versa) after it is properly connected and manipulated through a program.

Is 512 SDR RAM or 256 DDR RAM better?

512 SDR. DDR2 is better, but more the memory better it is for your PC, irrespective of the memory technology. You have a point there but considering the current trends, i will prefer the DDR because sdram is being replaced with ddr. Especially if you planning to buy a new mother board, most MoBo's nowadays are of ddr. But speed and capability is better than having plenty of ram. It is with the speed of access not only the space. Besides, it's better to consider efficiency, right?

Should i buy a graphics card of the same type so i can use SLI or just buy one better graphics card?

Well the good thing about getting 2 video cards and linking them is that if one card dies you still have another to use until you can buy a new one. Also you can buy 2 less expensive cards and combine them into a card with like 1-2GB of ram. On the other hand I have heard from friends of mine that combine card that sometimes it can be a pain to get everything working correctly. I have never used SLI or Crossfire, I think it's still called Crossfire.

Personally I have always gone with saving up my $$$ to purchase 1 great card. I used to be a huge ATI fan even though I always ran Intel chips. But after many years of many problems dealing with ATI I switched to Nvidia. The card I run now I bought like at least 3 years ago. It is an Nvidia 250 with 1GB of GDDR3 ram. Even though it is old I can still run games like Battlefield 3, SW:TOR, and even Mass Effect 3 on 1440x900 resolution using Medium Medium-High options when it comes to Anti-Aliasing & stuff like that.

Not sure if that will answer you question or if it even helps you out. I guess it really all depends on what your system specs are and if you feel comfortable enough to mess with things like SLI.

Interactive input devices?

Interactive input devices are those that give the user feedback as they are used to feed in data. An example is a touchscreen, which doubles up as an output device.

Where is the port for adding R134A on a 1996 Buick Regal 3100?

it is under the air filter box. take out the 4 screws that hold the top to the bottom, then remove the top of the air box. use a 10mm socket on the bolt next to the battery and take off the bottom. then you will see the a/c accumulator. the port is right there. hope it helps.

Why wont Nintendo ds accept r4 chip?

Do you have a micro SD chip? That's probably the issue.

How do you stop Pentium fan noise?

Either by replacing with a new heatsink or unplugging the fan. I do not recommend unplugging the fan, it will probably over heat your system. I do recommend buying a zalman CNPS9500 and installing that to cool your processor quietly.

What is the porpose of having two pci express graphics slots?

This allows either Crossfire or SLI to be used. This means there are 2 separate graphics cards linked together to provide increased performance

Can you use an SD card as a virtual memory page file on windows?

you can. but its a bad idea. page files are for frequent write operations, and flash memory has a limited write cycle lifetime. its like 500,000 cycles or so, but you will still wear it out pretty quickly as a page file. mount it as a folder under the main drive as c:\program files2\ or something if you want faster program load times, but really, its not worth it... yet.

This has been tried and most people who have done this have noticed little if any performance gains. The reason is simple: The pagefile is used as temporary storage for data that has not been recently accessed, and presumably will not be needed often. If it is needed often it will be in RAM. In most cases access to the pagefile is infrequent enough that increasng it's performance has no real impact on system performance. If the pagefile is accessed enough to effect performance you need more RAM. Nothing else will male much difference.

How fast does an Xbox 360 disk spin?

This one's a little tricky and is standard for all DVD players:

The disc's speed changes from 1530 rpm, when reading at the inner edge, and 630 rpm at the outer edge of the disk.

Does GeForce FX 5200 have Pixel Shader 1.1 or higher?

The Geforce FX 5200 has pixel shader 2.0 which is backward-compatible with pixel shader 1.1

So, yes, the FX5200 has pixel shader 1.1.

What materials do I need to build a CPU?

To build one entirely from scratch you will probably need several thousand dollars worth of assorted digital logic integrated circuits and just the CPU will be about the size of a two drawer file cabinet. Another easier possibility is to use one or more Field Programmable Logic Array integrated circuits, the hardware costs would be less than $1000 but costs for the development tools could be prohibitive (unless you can get permission from a company or university that already has licences for the development tools needed by the Field Programmable Logic Array you selected).

Don't bother trying unless there is some very special need for a unique type of computer, just buy an off the shelf microprocessor.

Will flash memory replace hard drives in the future?

It's very likely flash memory or another form of it (with no moving parts, unlike hard drives) will replace hard drives in the future, with advancements in memory capacities and decreasing costs. The aspect of no moving parts allows greater portability, endurance to movement (that's why your iPod nano has a flash memory) and no 'mechanical failures'.

However, flash memory at the moment (as flash drives) is up against a wall in the area of memory. This might be overcome with 'sideways' development' or another form of better, non-mechanical memory.

What is the difference between pci express 2.0 and pci?

PCI-E 2.0 ha s a higher bandwidth meaning more data can travel faster between the card in the slot and the motherboard/CPU. Im not sure of the exact numbers of data transfer speed but I'm sure the speed improvement is significant

What is the name of the girl on the ATI graphic cards?

I believe its Ruby but I could be wrong. I assume you are referring to the one that appears on reference sample graphics card made by ATI and not an ATI card made by another manufacturer, in which case, they probably have no name

Remove DVD drive from acer 3000 notebook?

There's only one screw but it's well hidden

1. At the back of the laptop remove the three screws on the support posts for the screen

2. Open the laptop fully and lift the plastic panel that has the power button.

3. Remove the 2 screws holding the keyboard in place

4. Carefully slide the keyboard towards the monitor and lift.

5. To the left of the keyboard ribbon cable is the screw that's been causing all this grief.

6. Remove, slide out optical drive, reassemble.
