Latest Technology in Computer Hardware
The rate at which new computer hardware products are arriving in the market is simply mind-boggling. As the technology advances, the size and the price of the devices come down, while the efficiency and capacity increase. The scenario is same in all cases, whether it is about internal components like processor, motherboard, RAM, graphics card, and hard disk or for peripheral accessories like mouse, keyboard, and monitors. Personal computers became popular only before about three decades back. But already there are huge piles of outdated and antique hardware components and devices. This is a tribute to the tremendous rate of development of latest technologies in computer hardware field. Perhaps, the newest entrant into the archeological catalogue of computer peripherals is CRT monitors. The sleek looking LCD monitors are spreading like computer virus.
Data storage devices have attracted considerable attention of the technology developers. New kinds of storage devices such as newer versions of flash memory cards, hard disks using latest technology and disks of ever-increasing capacity are the results of advancement in latest technology in compute hardware. The memory size of the random access memory (RAM) cards is soaring to enable the smooth functioning of graphics animation software packages and streaming video websites. Also, computer motherboards have undergone substantial changes over the years. More and more functions are being added to the motherboard. Also, despite the incredible improvement in performance and functionalities, the price of these components has actually fallen steadily.
The most vital component of a computer is the microprocessor. It is in this field that a battle of developing latest technologies in computer hardware takes place. The pace of development of microprocessor increases as the competition between the major processor chip manufacturing companies, Intel and AMD, intensifies. Both the companies are engaging in a neck and neck competition and continuously outdo each other in introducing new technologies.
In the field of computer peripherals, the latest technology in computer hardware is in developing yet another version of wireless mouse and keyboard. The concept of wireless mouse and keyboard is about a decade old. But the development of these items is still a work in progress. The latest products of wireless mouse and keyboard are said to be highly durable and error free.
Some of the developments in the latest technology in computer hardware are gearing up for changing the present concept of desktop and laptop computers. With new developments making possible the convergence of mobile phone technology and computers, a new breed of fully functional palm-top computers are going to be introduced in near future. With touch screen monitors and without the need for a mouse, these gadgets are likely to become the next big leap in the constantly leaping technological development field.

How Computers Work - Journey Into The Walk-Through Computer
[Recorded 1990] How Computers Work: A Journey Into The Walk-Through Computer is an educational video produced by The Computer Museum and hosted by David Neil of PBS's Newton's Apple. Join David Neil and his four young companions on an entertaining and illuminating trek through The Computer Museum's one-of-a-kind, two-story working model of a desktop computer. The Computer Museum in Boston, Massachusetts was the predecessor institution to the Computer History Museum located in Mountain View, California since 1996. Sadly, the walk-through computer did not move to California with the Computer Museum's collection, but as you can see from this video, it was a very engaging exhibit.

Don't Throw Away Your Computer's Hard Drive Until You Shred it Properly
Disposing of old hard drives is easy enough to do, plenty of places will take them for free, and many are placed in machines for resale, or charity machines that go to the poor. However, there is a problem with sending off a hard drive to be recycled. You can delete the data, and send it to the recycle bin; however the data will still be there, hidden away, even after you empty it.
The standard delete function of Windows merely marks the file data that used to be on the hard drive as 'empty' which means it can be written over. This means that it could be months until all traces of the original data are unrecoverable on the hard drive. With a bit of simple data recovery software, anyone who takes your recycled hard drive could open up those deleted files and could find personal details, and even bank information, which could be used in Identity fraud or even to purchase products using your personal bank account.
While you cannot permanently delete files in windows, there are plenty of programs out there which can help you delete your files permanently. These work by overwriting the parts of the hard drive which were used to store your original file with new data. The software then deletes the new data. Most security programs which do this permanent delete will rewrite each block with new randomized data around 7 times by default, although they can be set to do it more or less times, according to your specifications.
Using some software which performs secure file shredding is incredibly important in today's world, especially when cyber criminals are looking for alternative ways to get hold of personal information. Fortunately most internet security packages come with some kind of file deletion tool, and there are plenty of free secure file shredding tools available online.
Free file shredding tools allow you to securely remove all trace data of your personal files from your computer, preventing anyone from recovering data from your hard drive should you choose to sell it, or donate it to charity. Getting the simple secure file shredding software takes minutes, but it could save you thousands of dollars in Identity fraud!
Some secure file shredding tools are better than others, you might want to look around for user reviews, and check out exactly what each one offers. Some file deletion software will use a variety of different algorithms, rather than just using the same method time and time again. This ensures that all your data has been securely shredded, and will be 100% secured from any prying eyes trying to recover your information!
Finding free file shredding software online is a great way to protect yourself from the abundance of dangers that you can find in the computer world, it ensures that the data you want to be securely deleted from your computer stays deleted. This extra level of both security and comfort provides you with the knowledge that your personal and financial data is recovered from your old hard drives.

Basic Information About Sound Cards
A sound card also known as "audio card" or "audio adapter" is a peripheral device of a computer which handles the functions related to sound. The sound card is attached either to an ISA (Industry Standard Architecture) or PCA (Peripheral Component Interconnect) slot on the motherboard of the computer. The sound card receives input sound from an input device (e.g. Microphone), records the sound and performs some manipulations and delivers the resulting sound as output. It basically functions as digital-to-analog converter which converts the input digital signal to an analog format. The output devices include amplifiers, headphones or some external devices using standard interconnects (e.g. TRS connector, RCA connector). The sound cards are commonly used in multimedia applications like music composition, editing video or audio, presentation/education, and entertainment (games).
The major functions of sound cards are:
a] Synthesis (sound generation from digital signals)
b] MIDI (Musical Instrument Digital Interface: a standard protocol which allows electronic devices communicate, control and synchronize each other. Simply we can say that MIDI allows exchange of system data)
c] Analog-to-Digital converter (e.g. converts the input analog sound signals from microphone to digital mode)
d] Digital-to-Analog converter (e.g. reconverts the digital signals to output analog signals)
The sound synthesis includes three methods. They are FM (Frequency Modulation) synthesis, Wavetable synthesis and Physical Modeling.
Before the invention of sound cards it was widely believed that computers are not designed to produce sound or music. The computers then, had an internal PC Speaker which could deliver only a beep sound, which was produced occasionally as alarm or warning. Eventually, computer programmers thought of giving beep as accompaniment for the games. Even then they could produce only beep sound for the game. Initially the sound cards was designed and marketed for IBM PC , based on specific audio applications such as music composition (AdLib Personal Music System, Creative Music System, IBM Music Feature Card) or on speech synthesis (Digispeech DS201, Covox Speech Thing, Street Electronics Echo).By 1988 game companies such as Sierra started switching towards adding sound effects in games.
In the beginning, sound cards for IBM PC were manufactured by AdLib. The card was based on Yamaha YM3812 sound chip, aka the OPL2.At the same time; Creative Labs also marketed a sound card called the Creative Music System. The Creative Labs introduced the Sound Blaster card which created a major twist in the IBM PC compatible sound card market. The Sound Blaster had an additional processor for recording and play back of digital audio in addition to the AdLib model.
As of now, in the commercial market, sound cards are available in a price range of to costly models of 00.

HP proprietary motherboard and ability accumulation problems...
This is why specialized, proprietary systems are a bad idea. Trying to change a blown power supply in an HP desktop machine results in ridiculous expenses, or a whole lot of futzing around trying to get things to work, because this machine, like a number of HP models, does not use standard parts. They look standard, but they're just different enough to cause problems. www.cbserviceslondon.com
