BlackBerry Playbook, 60% touchscreen supply controls by Apple.




Following the Japanese quake, many analysts predicted supply issues for Apple's iPad 2 and upcoming iPhone 5. In fact, just today Best Buy announced that it would postpone sales of the second-generation iPad because of "supply constraints," while the iPhone 5 might be delayed until the second half of 2011 instead of the usual early summer refresh. 


To minimize the impact of shortages, Cupertino has reportedly been making aggressive moves to secure components from overseas suppliers. According to analyst Brian White of Ticonderoga Securities, Apple executives contacted suppliers "immediately" after the Japanese earthquake and offered upfront cash payments to ensure adequate supply


Meanwhile, ThinkEquity analyst Rajesh Ghai writes that Apple has secured approximately 60% of the total available touch panel capacity. This jibes with a recent DigiTimes report that claimed Apple's control of the touchscreen market will cause Research In Motion's BlackBerry PlayBook tablet to be delayed by a month, giving the iPad 2 a healthy head start. 


It remains to be seen whether delays will materialize, but Ghai notes that Apple's primary manufacturing source, Hon Hai, doesn't expect any shortages. Furthermore, he mentions that bumping the iPhone 5 to a fall launch could prove beneficial as it would give Apple more time to polish the handset, which would arrive during a stronger shopping season.

optical fiber, to send data to the speed of light




A technology that uses glass (or plastic) threads (fibers) to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.
Fiber optics has several advantages over traditional metal communicationslines:


  • Fiber optic cables have a much greater bandwidth than metal cables. This means that they can carry more data.




    • Fiber optic cables are less susceptible than metal cables to interference.


  • Fiber optic cables are much thinner and lighter than metal wires.




    • Data can be transmitted digitally (the natural form for computer data) rather than analogically.
    The main disadvantage of fiber optics is that the cables are expensive to install. In addition, they are more fragile than wire and are difficult to splice.
    Fiber optics is a particularly popular technology for local-area networks. In addition, telephone companies are steadily replacing traditional telephone lines with fiber optic cables. In the future, almost all communications will employ fiber optics.

    How to Install an Intel 845G Motherboard and also tips when handle the computer hardware.




    Installing a new motherboard can be a daunting task. As the central hub of your computer, a proper installation of the motherboard is vital. For those who own an Intel 845G series board, installation is straightforward. You’ll have your computer up and running in no time, and rest assured your motherboard is safe and secure.


    1. Install the motherboard’s I/O shield into the case. This plate sets up your case to fit precisely with all the connections at the back of your motherboard. You might need to take out the default I/O plate present on your computer’s case already. Press firmly from the back of the plate, and it should snap out of place. Install the I/O shield included with your Intel motherboard by pressing it firmly into the slot from inside the case. The shield should snap into place
    2. Screw your motherboard onto your computer case. The board attaches to the case via eight clearly marked mounting holes scattered around the motherboard. Use screws to mount it to your computer’s chassis. Make sure risers are used (unless your case has risers built in) to ensure the motherboard does not make contact with the metal of the case, as this can cause a short circuit.
    3. Install the processor heatsink base to the board. Insert the four white pins of the base into the corresponding holes located around the processor.
    4. Install the processor. Raise the processor socket lever on the motherboard. Drop the processor into place ensuring the processor and the socket are properly aligned. Return the socket lever to its original position to lock the processor into place.
    5. Install the processor’s heatsink. To do this, insert the four heatsink pins into the corresponding holes in the heatsink base. Press gently on each of the four pins to lock them in place with a click. Connect the heatsink’s power cord to the fan connector located to the left of the processor socket.
    6. Connect all remaining PC parts. Refer to the hardware manuals to ascertain how to connect the parts to the motherboard.
    7. Connect power to the motherboard. Take the 20-pin connector from your power supply and connect it to the appropriate socket on the left side of your motherboard.

    Warning and Tips
    • Never work on computer hardware while it has power going to it.
    • Always handle the motherboard by its sides, to avoid a transfer of corrosive oils from your fingers.
    • Always ground yourself with an anti-static wrist strap when working with computer hardware.

    Intel Motherboard Features


    Intel motherboard designs come in four primary sizes, each with their own unique characteristics. Regardless of the wide differences, there are some general features which they all share to some degree or another: memory, expansion, storage, and integrated peripherals.

    Size and socks are closely related in that the largest intel motherboard series on the market is designed specifically to host multiple Xeon-server class chips, while the tiniest ITX Intel motherboard series is only used for mobile CPU sockets or even Netbook/Nettop CPU sockets for Intel's ATOM family of budget CPUs. The middle two groups, ATX and Micro ATX, are both home to desktop CPU sockets, though there are a few server ATX motherboards, and at least one Micro ATX Intel motherboard featuring a socket designed for use with laptop CPUs. Obviously the larger the motherboard physically is, the more features it can integrate.

    One of those features is memory sockets, which are becoming more and more important as 64-bit CPUs and 64-bit software continue to gain traction in the market. One of the main benefits of going 64-bit is the ability to address large amounts of system memory, but all that memory needs a place to plug into any Intel motherboard. This is where memory sockets come in, and larger Intel motherboards tend to have more of these than smaller ones because they tend to eat up relatively large amounts of physical space. Because most Intel motherboard designs support dual- or even triple-channel memory configurations, many memory sockets are found in pairs or in trios. The memory sockets are usually designed for very specific types of memory that operate within fairly limited tolerances when it comes to speed (MHz) and electrical requirements.

    Memory and CPU sockets are not the only things that can be plugged into most Intel motherboards. All but the very smallest Intel motherboard designs feature slots designed to accommodate various add-in cards ranging from graphics adapters to high-end RAID array devices. These are generally referred to as 'slots' and come in AGP, ISA, PCI, PCI-X, PCIE, PCIE-G, and many other styles and types. Some types such as AGP are only useful for specific types of add-in modules, while other slots such as PCIE all general purpose and allow any Intel motherboard to be expanded and customized to perform any number of customized tasks.

    Of course, many of those very tasks that once were exclusively handled by add-in boards are now part of the standard array of integrated features. Onboard sound, networking, USB controllers, SATA, and even advanced RAID controllers are all very common any almost every single Intel motherboard on the market. While some of these features such as RAID controllers come in many flavors, the general rule is that one gets what they pay for; a more expensive Intel motherboard will be more likely to have a more powerful integrated RAID controller. Some of these integrated features may work well for today, but having expansion slots helps to ensure that future upgradability and expansion without complete system replacement is possible if any portion of the integrated feature set is ever deemed insufficient.

    SATA and PATA, what is the different of both technology for your computer.


      Examining Serial ATA's (SATA) comprehensive set of features illustrates how SATA addresses the shortcomings of Parallel ATA and the reasons for SATA as an ideal choice for deployment in enterprise-level and external RAID subsystems.
    Hot-Plug Capability
    Parallel ATA is handicapped by its inability to support hot-plug drives. Any Parallel ATA-based RAID solution requires the host bus into which the degraded array's RAID controller is plugged to be powered off before the failed drive can be replaced. The alternative is to continue using the degraded array that offers reduced throughput capability. Clearly, neither option is acceptable in an enterprise-level environment where 24x7 availability and high performance are important requirements. It is easy to see why SCSI and Fibre Channel that support hot-plug drives have not yielded any ground to Parallel ATA in the enterprise space in spite of ATA's cost advantage. With its support for hot-plug drives, SATA remedies this deficiency.


      Decreased Width and Increased Length of Cables
    Parallel ATA's ATA/ATAPI-4 standard improved signal integrity by introducing the 80-conductor cable with 40 conductive elements serving as grounds to reduce cross talk between adjacent signal lines. Though the increase in the number of conductive elements did not increase cable width over the existing 40conductor cables due to the use of thinner gauge wires, the width of these cables nevertheless impeded airflow necessary to cool a server and constrained chassis design. Furthermore, Parallel ATA continued to limit cable length to 18 inches that prevented efficient routing of its cables within chassis to reduce clutter and improve accessibility to components in the system.
    SATA addresses the limitations of Parallel ATA by more than doubling cable length to 1 meter and using data cables comprised of only seven conductors--a pair of differential signal lines for transmitting and another pair for receiving, and a ground between and at each end of the transmission and reception pairs. These thin, flexible cables (with connectors only 8mm wide) can be conveniently routed to multiple drives with a very small footprint, albeit with some constraints on its bend radius. This feature is highly attractive to servers using internal RAID with high drive density.
