More and more these days, users of portable electronic devices are storing data on portable memory sources. This is true especially for users of mobile phones, portable global positioning system (GPS) devices, and video and audio players and recorders. One of the primary formats for these portable memory sources is a microSD card.
A microSD card is one of the smallest flash memory cards on the market today. It is manufactured by SanDisk, which lends the SD to the name. The other part of the name comes from the tiny size of the card.
SanDisk originally manufactured the SD card, which was a bit larger than the microSD card. Then came the miniSD card, which was a bit smaller. Finally came the microSD card, the smallest of them all.
As its name suggests, a microSD card is tiny. Most technical measurements for the microSDcard put it at 15x11x1. That's millimeters, of course, and the card is roughly the size of a fingernail. In the race to store more information in less space, the microSD card is at the head of the class.
How many gigahertz in 320 gigabytes?
The two terms apply to entirely different things. Gigahertz is a measure of speed, 1 gigahertz = 1 billion CPU clock cycles per second, a gigabyte is storage space and is equal to a billion bytes
Is the most complicated component in a computer?
The CPU is arguably the most complicated component inside of a computer, with modern processors having over 2 billion transistors stuffed into the space of an over-sized postage stamp, although some video cards are also approaching that level of complexity as well.
How do you reboot acer aspire 5100?
Assuming that you can't do it from windows by going to start-->shut down-->restart-->ok, you should be able to reboot it by holding down the power button for about 10-20 seconds.. That should cause it to turn off. Then just turn it back on.
Microsoft Corporation (NASDAQ index: MSFT) was created in 1975 by Bill Gates & Paul Allen.
Which connecton type supports upto 127 peripherals in a single connections?
Theoretically, you can use a USB port to connect up to 127 devices. To do so, you would need to use hubs. The problem with using hubs is that they count as devices. Thus if a hub has 4 sockets, it counts as 5 of the 127 devices.
What storage devices contains no moving parts and connect directly to a USB port?
Assuming you mean a data-storage device (for use with computers) then the most clear cut answer would be a CD-ROM or a DVD-ROM, neither of which have any moving parts by themselves. The disc-reader however would have moving parts which may negate the idea of a stationary storage device.
Flash memory is another form of storage which is commonly found in USB drives and small electronics. It has no moving parts.
Most important hardware components needed for gaming and web surfing?
Graphic Card , Ram are the important most importing for gaming and web surfing :)
Vm-ware is the software allows us to install 2 O/S in your PC. Then we can use both operating systems by minimizing the window. It allows to use parallel Operating systems. sorry if the answer is not right.
Where is the functions key on a laptop?
It is the key that allows the standard keys on the keyboard to have additional "functions". Common uses for the function key include turning the keys IOPKL;M,. into a number pad. Also function keys are used for things like lowering and raising the speaker volume, putting the laptop into sleep/hibernate mode, changing the display used for output, and launching favourite applications.
The EDO RAM desktop memory modules have 72 pins and operate at 5V as standard
List four symptoms that indicate a faulty power supply?
1) The power reading (battery moitor) changes frequently, up and down, or is always unsure 2) The computer shuts down through loss of power when it seems to be on full power 3) the power cable is damages, very old or has been faulty in the past
It takes some experience to know when this type of failure is power related and not caused by the memory. One clue is the repeatability of the problem. If the parity check message (or other problem) appears frequently and identifies the same memory location each time, I would suspect that defective memory is the problem. However, if the problem seems random, or if the memory location the error message cites as having failed seems random, I would suspect improper power as the culprit. The following is a list of PC problems that often are related to the power supply: * Any power-on or system startup failures or lockups. * Spontaneous rebooting or intermittent lockups during normal operation. * Intermittent parity check or other memory-type errors. * Hard disk and fan simultaneously failing to spin (no +12v). * Overheating due to fan failure. * Small brownouts cause the system to reset. * Electric shocks felt on the system case or connectors. * Slight static discharges disrupt system operation. In fact, just about any intermittent system problem can be caused by the power supply. I always suspect the supply when flaky system operation is a symptom. Of course, the following fairly obvious symptoms point right to the power supply as a possible cause: * System is completely dead (no fan, no cursor) * Smoke * Blown circuit breakers
In a system that uses a CD drive were the audio wire connects?
There is a data cable,and a power cable that connect the drive to your PC.
Everything is done with the data cable, there is no audio or video wires.
Its more of an bidirectional device......it shows u the output graphic data as well as helps u select ur option.........
What is the difference between a CD burner and a CD writer?
It's the same with DVD optical drives. A Blu-Ray reader (or player) is a drive or a stand alone home theater appliance that can play or read Blu-Ray movies or read Data on Blu-Ray discs. A blu-Ray burner is a drive that can write or "burn" data on Blu-Ray discs.
I'm actually using a USB Blu-Ray burner with my system. It's from a company called DIGISTOR. Very very nice. Hope the answer helped.
In the back of most desktop computers are removable tabs that cover slots that have been cut into the frame. When you remove the cover from your computer you will see that there are slots which align with the tabs. A tab can be removed and an interface card can be installed at that location. PCI BUSS and PCI slots are one of the types of communication formats used by desktop computers.

How do analog and digital computers differ?
A digital computer processes discrete data, an analog computer processes continuous data.
- Discrete data (integers, character codes, boolean values, encoded floating point numbers, etc.) represent information with sharp discontinuities between represented values. Any data value not exactly encoded must be approximated by one of the nearest encoded values. Operations on discrete values are more reliable and consistent, but usually slower with identical technologies.
- Continuous data (voltages, currents, fluid pressure, fluid flow, shaft position, shaft rotation rate, etc.) represent information by analogy. All data values (within the limits of the machine) have an equivalent representation. Operations on continuous values are less reliable and less consistent, but usually faster with identical technologies.
Analog computers are typically harder to program: they are either designed for one special purpose with the program permanently built in, or they must be "rewired" to reprogram them.

FOR THE TEACHERS
You can't make the students learn better by changing the answer to the wrong one.
The humanity is positively progressing because the internet allows people to share the knowledge much faster.
By changing the answer to the wrong one you will only succeed in producing more Ds
Progress is= to knowledge share, do not slow it down!!!

P.S. A student is here because either he/she is not interested in a subject or a teacher is not good.
What is the average memory of RAM in a computer?
Most computers in 2008 come with at least 1 GB (even laptops). You should get around 2 GB if you're going to do alot of work on the computer such as editing photos or editing videos. However, for a casual user who is surfing the web or using MS Word/Excel, even 512 MB would be enough.
What could cause a computer monitor to burn out or die?
I had a 17" CRT that died in front of me one day - and it taught me an important lesson. I was working at my home PC when I heard a faint pop sound, and the screen went dark. Living by the philosophy of looking for the most likely causes first, I checked the power cable (fine), the power strip (also fine), then completely disconnected the monitor from the PC and power, got out the screwdrivers and openedup the casing. I pulled out a fuse and used a tester on it; sure enough it was blown, and I could fix it for about $3.99 and a 2-minute visit to the hardware store across the street. If I had taken it into a repair shop, it would have cost me $50 just for them to open up the case and replace it themselves.
Which is the smallest increment of data in a computer system?
A bit is a binary digit that is the second smallest increment of data on a computer. It can hold only two values which are 0 and 1.
AMD (acronym for "Advanced Micro Devices") is a US-Based manufacturer of semiconductors and computing products. Some of AMD's consumer products include: laptops, desktop computers, tablets and embedded computing solutions.
Which multimeter setting to test power supply of a computer?
That depends on what you're testing it for.
You would mostly use the volt meter settings to test for proper voltage output at the connectors coming out of the power supply. After verifying the expected volt output from a suspect connector, You should, in case you are wrong or a short is present, start with the highest voltage AC settings first and then reduce to lower settings and DC to confirm proper outputs.
