Computer Hardware

Any portable data storage needs

USB stands for Universal Serial Bus and is a standard means for connecting devices such as flash memory, printers, cameras etc. to a computer.

Compaq was acquired by Hewlett Packard. Before the acquisition the ticker symbol was CPQ. The ticker symbol for Hewlett Packard is HPQ.

Finger print scanner, eye scanner (for high security area) ect.

Let A,B,C are inputs and Y is the output.

Mind it that Y=A+B+C is a logical operation in our case i.e. OR operation. It's not an arithmetic operation (i.e. not a sum operation).

A touchscreen is hardware.

In my younger days,we had row houses.They were all in a row and all looked the same. as in mill hill houses.The mills would build houses and rent them to the mill workers.There is an old saying "I owe my soul to the company store" this also came from the mill hill villages where the mills owned the houses,stores,everything!!

ADDED: As a Transatlantic difference, if these what I think they are - all joined into a long, single building - in the UK they are called "terraced" houses. Although an 18C concept they did become particularly associated with 19C industrial (not just mill) towns, but a lot of modern housing developments now are of terraced form.

The "company store" ethos was used in Britain too, but its inherent unfairness led to its legal abolishment under a 19C law I think called the "Truck Acts".

Your laptop probably doesn't support higher than an 667 MT/s FSB, so no. The fastest processor that would likely work in your laptop would be either a Core 2 Duo T5850 or a Pentium Dual Core T3400, both at about 2.1 GHz.

It depends. are you talking about buying like add-on cards? buying a headset? upgrading to a blu-ray? or building an entire computer? Since you weren't very specific, i'll answer all 4.

1. For add on cards (sound cards, graphics cards, etc) there aren't very many limits , but there are some. Such as power supply (do NOT want to be under powered), and slot availability (pci/pci-e).

2. for headsets, as long as the manufacturer of said headset makes the drivers for whatever operating system you're running, you're good.

3. blu-ray drives, or any other optical drives, don't have very many limits either. Make sure your power supply has the proper cables to provide power, make sure you have the proper data cables to connect to your mobo. and of course make sure it fits in your case.

4. Building a computer is obviously more complicated than the other 3 but not too difficult at all. i would say start with deciding which processor you want and then build off that. (cpu cooler if necessary, mo.bo., ram, hdd/ssd, graphics card, odd, power supply, etc.) for the processor it really all depends on what you are going to be doing with said computer. if you are only going to be word processing or surfing the web, a core i3 would be sufficient. however the other extreme would be video editing and 3D modeling for which i would say ATLEAST a core i7 2600k, but more likely a i7 3930k. if you're somewhere in between well get something in between.

Hope I helped,

Here is a short explanation.

Clock rate or clock speed is the speed at which a microprocessor (CPU) executes instructions. Clock speeds are typically expressed in megahertz (MHz) or gigahertz ((GHz). A single clock cycle (usually shorter than a nanosecond in modern non-embedded microprocessors) toggles between a logical zero and a logical one state.

One cannot be said to really be "better" than the other. When a CD-R has been recorded to, it exhibits all the properties of a traditional CD-ROM. A pressed CD-ROM has a slightly higher theoretical lifespan, but real-world conditions place them at about equal rates of deterioration.

nope. no such thing on this planet. not true, it does exsist. i purchased a set of camera video glasses that uses the 3.5mm (1/8) male to usb connection. I lost that piece so i had to substitute or the ipod 4gig charger which uses the same 3.5mm to usb connection. Its hard to find but it does exsist.

Yes.. it reduces the time taken by the Hard drive to search for a file . thus, improving performance..

when you delete files and copy/make new ones.. they may appear sorted ( as in folders and disk drives).. but inside the Hard drive they are not in the same place but scattered over the magnetic disks (platters).

So when you open a program.. the hard disk has to look for the essential files all over the platters and hard disks have 1 - 3 platters.. so searching all of them is time taking

after the Defrag all the files are organised and when u open the same program the hard drive has to look only in one location to get all the essential files..reducing access time.

No, Microsoft's Internet Explorer is not available for Android. However, there is a wide range of internet browsers available for Android. Google provides an updated Chrome browser, Firefox has ported their browser to this platform, as has Opera. The Dolphin browser is also very popular.

The maximum distance an IrDA device can trasmit is 1 meter. The effective range between two IrDA devices is 2 meters.

Yes.

CD-RW and DVD drives can be either internal or external hardware devices.

Well, the main advantage is that computers are very good at doing boring, repetitive calculations very quickly. Modern computers can perform trillions of calculations per second. A normal human is lucky if they can average one calculation per second manually. they are accurate ,

calculators, um your input output cords tv to DVD (audio video IO), net bios, your computer (press F2 next time you turn it on before windows/mac starts). basic input/output system or syntax.

We can ensure the required hardware's are install or not through by the click of my computer property and then hardware tab and then driver singin...here will be list or required hardware and installd hardwares..

It is important to control access to hardware and data to limit the amount of information that any one employee might have. It is also a good idea to control hardware and data to make sure confidentiality is being protected.

Power supplies are need by many electronic devices for several reasons. Most devices need one or more DC voltages. Only AC power is available at a common household outlet.

Power supplies, among other things, usually must convert AC power to DC power.
AC = Alternating Current
DC = Direct Current
VDC = Volts of Direct Current

Computers, for example, need a power supply to convert 120 VAC line power to 6 VDC, 9 VDC and possibly 12 VDC. You will understand this more fully once you get further into the study of things like trigonometry, the calculus, basic circuit design, etc.

RAM: random access memory

At this point, I would say that a CRT had no advantages over a LCD monitor. The LCD is probably cheaper, it takes up less space, is easier on the eyes, and provides better revolutions.
