be captured. When technology of digital camera just started, the resolution is just 640x480 pixels. A year later as manufacturing techniques improved and technology emergence of “mega pixel” cameras. Nowadays, the resolution has increase to 7 mega pixels and resolution is keep on upgrading. Memory Storage Many of the first-generation digital cameras contained one or two megabytes of internal memory suitable for storing only around 30 standard-quality images at a size of 640x480 pixels. Unfortunately, once the memory had been filled no more pictures could be taken until they had been transferred to a PC and deleted from the camera. Modern digital cameras today use removable storage. These brings two main advantages, first is once a memory card is full it can easily be removed and replaced by another; secondly given the necessary PC hardware, memory cards can be inserted directly into a PC and the photos read as if from a hard disk. By early of year 1999, two rival formats were battling for domination of the digital camera arena:

CompactFlash : CompactFlash (CF) provides non-volatile storage and does not require a battery to keep data. Basically, it is a PC Card flash card that has been compact to about one quarter of its original size and uses a 50-pin connection to fits into a standard 68-pin Type II PC Card adapter. This makes it easily compatible with devices designed to use PC Card flash RAM. The measurement for CompactFlash is 43mm by 36mm. They are available in both Type I and Type II cards, even though majority is the former. A Type I card is 3.3mm thick and will operate in both a Type I and a Type II slot. A Type II card 5mm and will operate in a Type II slot only. By late 2004 maximum capacities had reached 512MB. SmartMedia : The Toshiba-developed SmartMedia cards are significantly smaller and lighter than CompactFlash cards, weighing 0.48g with a form factor of 45 by 37mm and a thickness of only 0.78mm. It uses its own proprietary 22-pin connection - but like its rival format is PCMCIA-ATA-compatible. Therefore, it can be adapted for use in notebook PC Card slots. Capacities are less than the CompactFlash. However, the cost per megabyte is similar to the CompactFlash.

Conclusion The technology of the digital camera is changing so fast like the technology of the mobile phone. It is not an easy stuff to choose a digital camera. We shall have our own guideline before we purchase a digital camera. First of all we need to set our own budget for purchasing of the digital camera then only we analyst the function and features of the digital camera that we wanted to purchase.

Answer No. 3(a) Introduction to LCD Display LCD (liquid crystal display) is the technology that used for displays in notebook and other smaller computers. Like light-emitting diode (LED) and gas-plasma technologies, LCD allows displays to be much thinner than cathode ray tube (CRT) technology. LCDs consume much less power than LED and gas-display displays because they work on the principle of blocking light rather than emitting it. The LCD is made with either a passive matrix or

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
