Computer Hardware

Most modern peripherals. USB devices, Firewire devices , SATA hard drives, PCI express cards and Ethernet are all examples of devices using serial communication.

In the context of computer systems, IRQ (Interrupt Request) lines are used by hardware devices to communicate with the CPU. However, there might be instances where you'd prefer certain devices not to use IRQs.

If you wish to prevent a PCI (Peripheral Component Interconnect) device from using an IRQ, you generally have to go through the system's BIOS (Basic Input Output System) settings. The BIOS interface varies among manufacturers, but usually, you can access it by pressing a specific key (like F2, F10, or Del) during the system startup.

Once in the BIOS settings, look for options related to IRQ assignments for PCI devices. This setting might be under different menus based on the specific BIOS version. Once located, you can change the IRQ settings to manual and then disable the IRQ for the specific PCI slot.

Remember that changing BIOS settings should be performed with caution, as incorrect configurations can lead to system instability. Always ensure you understand what each setting does before making adjustments. Also, refer to your motherboard's manual for specific instructions.

It captures and records images and these can be stored on a computer.

They are installed in groups or banks of two. Most older motherboards that use SIMMs have one to three banks that can be filled with two, four, or six SIMMs. 72-pin simms are installed into groups or banks of two

A scanner is a flat-bed or hand-held optical reader, used to scan paper documents and photographs/graphics into the computer.

The central processing unit (CPU) is plugged into the motherboard. Everything else in the computer is directly or indirectly plugged into the motherboard. There are expansion boards, for instance, which have all kinds of processors on them, but they are plugged into the motherboard meaning it is the base board that everything ultimately connects to, like the foundation of a house.

This creates a connection from everything to the CPU. This is necessary because the CPU, like the motherboard, is central to the control of the computer as a whole. It ultimately controls the lowest level functions of the operating system and actually controls most things that happen in a computer. Actually, more than saying control, it is most of the work of the computer. It does the numeric operations that are what a computer, for the most part, does.

CPU = brains, motherboard = connections to the periphery

*winks*

there are several answers i could come up with for this one, depending on the OS you use, many systems use empty hard disk space and convert that into what is called "virtual memory." so systems use both, actual memory installed, and virtual "paged" memory. so to simplify the answer, the more memory you have, the less time programs have to use your hard disk "memory" to finish, or run tasks. when your drive is being accessed for memory, it takes away access time for applications. The limiting reagent model: your system can only go as fast the the slowest reagent. Information moving from memory to CPU - fastest, speed of current Information moving from Hard drive to CPU - slowest, friction of drive turning to access information More memory means more information can be stored electronically and be accessible electronically. Of course, all of this must take into account your OS and how the program you want to run is coded. If the program will not load into memory but constantly accesses the hard drive by design, more memory will not help it so much. More memory really comes into play with the processes behind the scenes in Windows. By having more space for Windows XP to run free, you allow necessary functions to flow quickly.

Core is the centre part of any celestial body.

In electrical terms a core is an iron frame that wire coils are wrapped around to concentrate the magnetic flux that surrounds a wire when current flows through it. A good example of a core is in a transformer where both the primary and secondary windings are wound on to the same core. The magnetic flux that surrounds the primary coil when it draws a current will cut the secondary coil and induce a voltage into it. The core concentrates and directs the lines of magnetic force for maximum use by the secondary coil.

PCI stands for Personal Computer Interface, and it is the current standard for most types of non-video expansion ability in computers. The cards themselves allow you to expand the operations of your computer; for example, adding more hard drives, better sound output, and extra USB ports. The cards connect to the motherboard through built in slots and have a direct path to the processor.

The characteristics of the input devices can be classified into the numbers of degrees of freedom, the mode of sensing and the type of technology used. The mode of sensing can either be isometric or isotonic.

I experienced this problem this moning, the answer was not that difficult to track down.

I am running vista x64 and the answer came from HP Advisor. Upon starting the computer I plugged a memory stick into the card reader but the operating system did not find it. I went to my computer to see if I could find it as a drive that was now plugged in and I would load it from my computer. I noticed that there were no drives showing except the hard drive and DVD drives. All the USB and Media drives were absent. After several attempts at trying to find the Media card I had plugged in, I thought, try the HP advisor (the media reader was supplied by HP). After finding it in the FAQ It was a matter of starting Media Centre to check if in fact the media card had been read. The next step was to shutdown Windows and unplug the power cord. Wait a few seconds. Reconnect the power cord. Start the computer again while holding the start button for five seconds. Once the computer restarted and the windows screen came I went to My Computer and there were my USB and media reader drives.

The touch screen only reports "grid" locations.

The only reason you could lose space is corruption in the Master File Table, and the only fix is to reformat your disk you can't delete space from your hard drive unless you replace it with a smaller one.

If you are asking about what happens if you choose to "wipe" or "delete" the free space, that just means that the free space is overwritten. You would overwrite unallocated space for privacy and confidentiality reasons. Since that is free space, no harm would occur if it were overwritten. Now, if you have an SSD drive, then you'd do better to Trim the drive, since that would reformat any previously used but unallocated blocks without adding unnecessary wear to the drive.

Software. Short and sweet. Hardware needs software to work.

LGA Sockets, most often used by Intel place the CPU Pins in the motherboard instead of on the CPU.

For your viewing pleasure:

PGA Sockets place the pins on the CPU

BGA Sockets solder the CPU to the motherboard, and use rounded beads instead of obvious pins

Slot Sockets look and behave in a manner similar to PCI, and have card slot arrays instead of individual pins

DIP Sockets place the pins only on the outer edges of the chip. These are old and crude.

PLCC Sockets have metal fins on all four sides, with a small chip that fits inside. This chip has receiving points that are flat against the chip, giving them an appearance similar to that of a game cartridge. (Some New BIOS chips still use this. Little chip nested inside of a brown plastic square)

Think thats about it, though I'm sure there's a socket type I missed somewhere!

Yes, you can change the floppy drive but you'll have to take apart the whole laptop.

If you have no experience taking fixing laptop, I wouldn't recommend trying it.

But if you still want to try it, I'll post a link with Toshiba laptop disassembly guides so you can try.

If you are referring to IP address, this is a special identification number that is assigned to all machines connected to the internet or intranet. It is comprised of 4 sets of number ie. (64.54.123.26) Where each number can be anything from 0-255. This number is unique to each system and acts like a physical address for your computer. When you send a request for data this address is attached so the machine you send it to can know where to send its response. No two computers have this number.

No, Jack Kilby did.

Answer-- A device that can read text or illustrations printed on paper and translate the information into a form the computer can use. A scanner works by digitizing an image -- dividing it into a grid of boxes and representing each box with either a zero or a one, depending on whether the box is filled in. (For color and gray scaling, the same principle applies, but each box is then represented by up to 24 bits.) The resulting matrix of bits, called a bit map, can then be stored in a file, displayed on a screen, and manipulated by programs.

Optical scanners do not distinguish text from illustrations; they represent all images as bit maps. Therefore, you cannot directly edit text that has been scanned. To edit text read by an optical scanner, you need an optical character recognition (OCR ) system to translate the image into ASCII characters. Most optical scanners sold today come with OCR packages.

Scanners differ from one another in the following respects: # scanning technology: Most scanners use charge-coupled device (CCD) arrays, which consist of tightly packed rows of light receptors that can detect variations in light intensity and frequency. The quality of the CCD array is probably the single most important factor affecting the quality of the scanner. Industry-strength drum scanners use a different technology that relies on a photomultiplier tube (PMT), but this type of scanner is much more expensive than the more common CCD -based scanners. # resolution: The denser the bit map, the higher the resolution. Typically, scanners support resolutions of from 72 to 600 dpi. # bit depth: The number of bits used to represent each pixel. The greater the bit depth, the more colors or grayscales can be represented. For example, a 24-bit color scanner can represent 2 to the 24th power (16.7 million) colors. Note, however, that a large color range is useless if the CCD arrays are capable of detecting only a small number of distinct colors. # size and shape: Some scanners are small hand-held devices that you move across the paper. These hand-held scanners are often called half-page scanners because they can only scan 2 to 5 inches at a time. Hand-held scanners are adequate for small pictures and photos, but they are difficult to use if you need to scan an entire page of text or graphics.

Larger scanners include machines into which you can feed sheets of paper. These are called sheet-fed scanners. Sheet-fed scanners are excellent for loose sheets of paper, but they are unable to handle bound documents.

A second type of large scanner, called a flatbed scanner, is like a photocopy machine. It consists of a board on which you lay books, magazines, and other documents that you want to scan.

Programs using Optical Character Recognition technology (OCR) can use AI methods to try to deduce what the text is in a handwritten document. There is a good explanation on Answers.com - see related link.

Earlier Pentiums used a pin grid array ( PGA ) socket, with pins aligned in uniform rows around the socket. Later sockets use a staggered pin grid array ( SPGA ), with pins staggered over the socket to squeeze more pins into a small space.

Depends on what you mean by calculations. An i7 3770k can perform up to 150~GFLOPS, or Giga-Floating Point Operations per Second. This number looks like this

150,000,000,000~ Floating Point Operations per Second. This is probably the number you're looking for!

As far for Instructions per Second.. This one is more advanced. The same i7 3770k, which is the processor with the highest Instructions per Cycle currently available in the modern CPU market, has an Instructions Per Cycle count of 3.5~

So, per second, this would be the following:

3.5 *3.5 Ghz= 12,250,000,000 Instructions per Second.
