The translucent cell phone concept is not a new one, but the Window Phone incorporates an extra, gimmicky but fascinating element—weather.
Sure, when it's sunny, the window looks clear. But when it's cold, the window looks frosty. And when it's raining, oh man, it looks like tiny droplets are all over the screen.
I mean what a pain in the ass, but what a FANTASTIC pain in the ass.
In computer architecture, a bus is a “subsystem that transfers data between computer components inside a computer” or between computers. Each bus defines its set of connectors to physically plug devices, cards or cables together.
Data bus- The channel, which carries data between the processor and other device in both directions.
Address bus- The channel, which carries the address indicating form/to where date should be read/written. (Mainly work between CPU&RAM)
Control bus- The channel, which carries the control single form the CPU to other devices. (Control- check the status of the device whether 1or 0)

Serial & Parallel Data Transmission
Serial: Term used to describe the process of transmitting information one bit at a time, or sequentially.
Parallel:Action that is performed at the same time as another. For example, a communication that sends multiple bits of data each second.
INTERNAL BUSES
Term used to describe a device that is installed within the computer
EXTERNAL BUSES
Also known as an”input/output bus” or “0/1 bus,” it is the “data pathway that connects peripheral devices to the CPU”.
ISA (Industry Standard Architecture): This bus is the 16-bit ISA slot low speed work horse of the system. You will commonly fine a sound card hooked up this type BUS.
PIC (Peripheral Component Interconnect): Support 32-64 bit bus and is the reigning standard of external buses. The PIC is fast and is slowly marking the ISA fade away. Go with a PIC Bus Card when possible
IDE (Intelligent Drives Electronics): This bus is used mostly for disk drives and connects up to two devices on one connection. More than likely you’re hard drive and CD-ROM are connected through this type bus.
AGP (AcceleratedGraphicsPort): This bus provides form 2 to 4 times the speed of the PIC and is used for video expansion only. If you have this slot on your motherboard make sure and use it for you video card. This is great way to go and takes a lot of stress off the CPU, thus gaining in performance all the way around.
A basic definition: Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced.
In its original sense, 'nanotechnology' refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products.
The first computer used Vacuum Tubes for circuitry and magnetic drums for memory, and was often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions. First generation computer relived on machine language to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.
The UNIAC (UNIVersal Automatic Computer) and ENIAC (Electronic Numerical Integrator And Computer) computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951.
Transistors replaced vacuum tubes and used in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 50s. The transistor was far superior to the vacuum tubes, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable then their first generation predecessors. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched card for input and printout for output.
Second-generation computers moved form cryptic binary machine language to symbolic, language, which allowed programming to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN. These were also the first computers that stored their instructions in their memory, which moved form a magnetic drum to magnetic core technology. The first computers of this generation were developed for the atomic energy industry.
The development of the integrated circuits was the hallmark of the third generation computers of computers. Transistor were miniaturized and place on silicon chips, called semiconductors which drastically increased the spend and efficiency of computers.
Instead of punched card and printouts, user interacted with third generation computer through keyboard and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors
The microprocessors brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip, what in the first generation filled and entire room could now fit in the palm of the hand. The Intel4004 chip, developed in 1971, located all the components of the computer-form the central processing unit and memory to input/output controls-on a single chip.
