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.

More often than not, also depending on the type of PC lover you are, you will find that it is mostly the Graphics card that will use most power. Unless you have a built in grahpics card, then it will most likely be the motherboard.

You can look on the back of the computer to see if there is an RJ-45 jack. This is where you would plug in an ethernet cable. It looks like the telephone jack only slightly larger.

Or, right click on "My Computer", select Properties, Click on the Hardware tab, click on Device Manager and see if there is anything listed under Network Adapters by clicking on the + sign.

Surgeons use robotics, highly advanced technology that is very precise beyond normal human capabilities, to perform delicate operations.

If you have them you could plug in additional fans allowing the tower to stay cooler.

The most commonly used input device for interacting with personal computers and many digital devices is the keyboard. The keyboard allows users to input text, numbers, and various commands into the computer. It is a fundamental input device and is widely used for a range of tasks, including typing documents, sending emails, browsing the internet, playing games, and executing various software functions.

Keyboards come in various forms, including traditional physical keyboards with tactile keys, virtual keyboards on touchscreens, and specialized keyboards for specific purposes (e.g., gaming keyboards, ergonomic keyboards). They are a fundamental tool for text-based communication and data entry on computers and are essential for many day-to-day computing tasks.

While other input devices like the mouse, touchpad, and touchscreen are also commonly used for specific tasks, the keyboard remains a central and universal input method across different computing platforms and operating systems.

You may be asked to write out the uses of computers in points in an essay. You could write that computers are used to process payroll, design business literature, as a method of communication and in animation.

The IEEE 1394 Interface or Port is also know by it's Apple Mac name as FireWire.

Again preference is a factor in this. Many brands work great for document scanning. There are many models out there that are designed for this purpose alone. Many of your popular computer makers such as HP, Epson and Fujitsu make excellent document scanners.

The CD ROM does not have any affect on the speed of the CPU or the speed of the Frontside Bus. The CPU and Frontside Bus is what carries data and the CD ROM is not connected nor involved with the speed of the computer.

Peripheral devices are devices used with a computer. Most think of peripherals as non-essential devices like printers, mice, joysticks, speakers, etc. The exact function depends on the exact peripheral.
