Where do you put the micro sd adapter on your computer?
If you are refering to SD Card adapter, there are the following methods.
If the adapter uses USB, then attach it to a USB port. (common)
If the adapter converts to firewire, plug it into a firewire port. (uncommon)
If it adapts mini/micro SD to SD, then slot it into a SD Card Slot.
How do you repair BSOD - Blue Screen of Death - on your computer?
Can depend on what caused it. It means the machine can't decide what to do next so it goes belly up (BSOD).
If you installed some new hardware the problem might be that....called a driver problem quite often. Need to uninstall it and read instructions or call manufacture.
Sometimes a simple restart will clear things up.
If you didn't installed anything, hardware of software and the machine is a few years old some component might have gone bad and the computer doesn't know what to do next. The next step is to open it up and start disconnecting things and restarting to find out what's causing the problem. This of course requires some 'puter knowledge, best left to the pros.
1.83 mb is 1873.92 kb
(1 mb is 1024 kb,so 1,83*1024=1873,92)
Can ProTools be run on PC without any additional hardware?
No,This cannot be done,You must have some digidesign, M-audio hardware or compatible control interface for pro tools to work
What happens when the power supply is bad?
Your system will probably won't even start.
randomly shuts down.
May cause failure to your system.
What is the difference between a modem and a codec?
* Codec is for coding analog data into digital form and decoding it back. The digital data coded by Codec are samples of analog waves.
* Modem is for modulating digital data into analog form and demodulating it back. The analog symbols carry digital data.
An external peripheral device must have a corresponding?
A peripheral device is a device which allows the computer to obtain information from its periphery - This may be as simple as a power button (which does not directly control the supply of mains to the machine, but rather signals to the power supply) or a HID (Human Interface Device).
Examples of HID include Mice, Keyboard, joysticks and gamepads, trackballs, trackpads... In fact anything which we use to provide information to the computer.
Any device which is connected to the computer must have a method of communicating with software which is running on the computer.
Early peripheral devices were always connected with cables however today peripheral devices can connect via one of the following means:
Any radio frequency method (includes Bluetooth, Wi-Fi, etc)
Mobile Phone
Infra-red communications are less commonly used but still supported.
A device could communicate with the computer via a network, this could mean that the device can be connected 5 feet or 500 miles away and it will appear the same to the computer (except for network speed limits and delays)
I hope this helps!
What is the primary purpose of file compression utilities such as WinZip?
The program allows large files to be compressed for either sending via e-mail or transferring to another source (e.g. from desktop computer to laptop). One must have the accompaning unzip program to allow the files to be redistruted to whatever source was chosen
How do you turn on an old AT power supply without motherboard?
AT power supplies typically use a mechanical button or switch to turn on. Depending on the age of the device, however, it may not be safe to activate it without a load, however. If no motherboard is attached, other devices that draw lots of power, like hard drives, should be attached.
What is different about the XT AT 286 and 386 motherboards from the 486?
They are the same size, but the processors are slower. ( The XT was a 16-bit 8088 computer, the AT was a 286 processor, a 386 was advanced enough to have virtual memory. The 486, even more powerfull had a built in math co-processor for the most part ).
What is the part in the computer that performs most of the tasks you ask the computer to do?
the processor, or CPU (central Processing Unit)
Why is accurate data important?
Accurate data is important because if someone tried to go off the outcome of your experiment with incorrect results then it could harshly effect their own experiment. It creates a domino effect. If one person goes off your false data then other people could go off theirs so on and so forth...
Mapping function between cache lines and main memory block?
I didn't quite understand your question but I'll answer you anyways :P..
It's known that the main memory is much larger that the cache memory , and we need to transfer a block of instructions to the cache memory to be frequently used by the processor to improve performance and reduce time spent in fetching instructions or data ( dealing with cache memory is much faster than RAM ). for example lets say that a main memory has a 128 data blocks and you need to place them in the cache memory which consists of 32 data blocks? then you have to have sort of technique to place them or MAPPING FUNCTION. And there are plenty of 'em (four mapping techniques as far as i know) i will just mention them without getting into details:
Direct mapping , fully-associative, set-associative and n-way set associative.
if you need more details just ask.
greetings
Can you please provide some help over Direct mapping , fully-associative, set-associative and n-way set associative
Thanx
What are the different types of memory modules?
The processor uses temporary storage, called primary storage or memory, to temporarly hold both data and instructions while it is processingthem. Pimary storage is much faster to access than permanent storage. however, when data and instructions are not being used, they must be kept in permanent storage sometimes called secondary storage, such as a hard drive, CD or floppy .
Which type of disk store up to 17 gigabytes of data?
No idea. A double-layer DVD can store up to 8 GB (too little), a Blu-Ray disc can store up to 50 GB (too much), a standard hard drive can currently store up to 2 TB (2000 GB, way too much).
I can't really think of any storage medium with an upper limit of 17 GB.
What is the main device that a computer uses to store information?
the hard drive is the main drive because it has all your windows information in it.
What are some devices that have input and output?
The devices that perform both input AND output operations are referred to as I/O (input/output) devices and their operations are called I/O operations. Examples of common input and output components are disk drives and modems. A touch screen monitor on an ATM or a video game controller that shakes when the player is hit can both be considered an I/O device. A CD or DVD burner would also be an I/O device, since it can both read and write data to discs.
Which hardware components are checked during the POST?
keyboard,mouse,cpu
,printer are connected properly or not will be checked during POST
What command is used to partition a harddrive?
The fdisk command is used to create and modify partitions on a hard drive. Be very careful when using fdisk. You could lose data and corrupt your hard drive if you don't know what you're doing. At the command line type:
$ man fdisk
to get the manual page for the fdisk command.
---- In Linux: After MUCH frustration, digging, trial-and-error, I have answered a related question.
My problem was that I could not delete or resize two "unallocated partitions on my hard drive. All the options (unmount, resize, delete, etc.) were grayed out. I could not unmount them because they were in use.
The answer was to download the GParted LIVE CD from: http://gparted.sourceforge.net.
I simply inserted the GParted LIVE CD, rebooted, and -- voila! -- I could move, resize, and delete all my partitions at will! IMHO, the GParted utility is much easier to use then Partition Magic, and best of all, it is FREE!
I hope this post can help others with a similar problem.

Can i add a router to another router?
Yes you can but you need reflash to firmware that allows you to do that like DD-WRT. Then follow the wiki to set it up as a repeater. Only the 2nd router needs this and the router has to to be on the list of ones that will take a reflash. (don't worry, its a big list) If you don't want to do the flash yourself eBay has them all done. (Just search for DD-WRT) Or Buffalo has a few models that ship with it installed new
What is the part of the computer where you can save information to a disk?
Computer data storage, often called storage or memory, refers to computer components, devices, and recording media that retain digital data used for computing for some interval of time. (Source: wikipedia)
What is the direction of information flow on the the address and data bus?
The address bus is unidirectional(only in one direction) in the processor. So, the flow of information on this bus is from the microprocessor to the attached device(memory module).
Are laptop computer hard drives interchangeable?
I'm not sure what you mean by interchangeable, but if you mean can you take one laptop hard drive and put into another the answer would most likely be yes. Assuming they are both based upon the same board communication function. You can't interchange a sata HD with IDE. If they are both Sata or IDE then there is no problem. You can probably tell if they are sata or ide by going into the computers bios. (Settings function before your computer boots.) You can also purchase an adapter that will allow you to hook up your laptop hard drive to your desktop. Hope this helps -Brent
