Computer Hardware

If you find that you are having network troubles the first thing to do is check to see if the cable is plugged in correctly. If it is, try pinging your loopback address. If that doesn't work that means that there is a problem with your NIC and it should be replaced.

In a serial connection, at any given time in one direction r the other, data is transferred across only one wire, one bit at a time. The usual example of a serial connection, DB-9, uses two wires, but still keeps to this rule.

No, a bar code scanner is not a storage device. The scanner is a peripheral device used to read the bar code on a product, and an associated computer can use that information to identify that product and provide pricing and other information about it. That identifying information and other data is held on a storage device associated with the computer.

Extra processor cores will only enhance system performance on heavy applications that support multiple core use. Most professional applications support this such as Adobe Photoshop support this. Extra cores will also enhance multitasking. To make a lighter system (smaller applications such as web browsing) run faster you need a higher clock speed. This is measured in Ghz.

Clients have to accept 4.75 to 5.25V and must be able to send configuration data as low as 4.4V. Hubs are allowed to drop as much as 0.35V.

By itself, a USB plug does not have to supply more than 100mA; however up to 500mA can be negotiated between device and host. Some USB hosts simply offer up 500mA from the get-go.

USB power supplies short the two data lines (white and green) which allows the device to probe for the fact that they're power supplies (i.e. that they provide the full 500mA without negotiation and that they won't respond to data).

The same way any set of speakers works - by sending an analog audio signal to an amplifier connected to the speakers. Whether the speakers are integrated into the monitor or stand-alone units, the wire from the speakers/monitor must be connected to the audio output of the computer. This wire terminates in a 3 conductor mini-phone plug. The jacket of this plug and the proper jack on the rear of the computer are usually light green in color. Under the jack, the mounting panel will have 'SPKR' etched into the metal/

You should let it run disk utilities when it comes on. If you cannot get into it, you might need to run a repair install of Windows.

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.

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)

No,This cannot be done,You must have some digidesign, M-audio hardware or compatible control interface for pro tools to work

Your system will probably won't even start.

randomly shuts down.

May cause failure to your system.

* 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.

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!

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

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.

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 ).

the processor, or CPU (central Processing Unit)

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...

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

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 .

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.

the hard drive is the main drive because it has all your windows information in it.

keyboard,mouse,cpu

,printer are connected properly or not will be checked during POST
