HPs new HP Mini 110 is a sleek, lightweight companion PC designed for Internet-centric consumers to stay connected to what is important to them, while at home or on-the-go. Offered in a variety of configurations and designs, the Mini 110 is small enough to slip into most purses, backpacks or briefcases and provides consumers with a choice of Pink Chic, Black Swirl or White Swirl HP Imprint finishes. The Mini 110 is as stylish as it is mobile, starting at 2.33 pounds and measuring just over 1-inch thick. With a 10.1-inch diagonal standard or optional high-definition LED widescreen display, a keyboard that is 92 percent the size of a standard notebook PC keyboard, and a built-in webcam and microphone, the new HP Minis are designed for consumers and business professionals who surf the web, check email, listen to music and need access to friends, family, co-workers or information.

An optical computer (also called a photonic computer) is a device that uses the photons in visible light or infrared (IR) beams, rather than electric current, to perform digital computations. An electric current creates heat in computer systems, the more processing speed is needed, the more electricity is required; all this extra heat is extremely damaging to the hardware. Light however doesn’t create significant amounts of heat no matter how much is used and therefore more powerful processing systems can be produced. By applying some of the advantages of visible and/or IR networks at the device and component scale, a computer might someday be developed that can perform operations 10 or more times faster than a conventional electronic computer.
Visible-light and IR beams, unlike electric currents, pass through each other without interacting. Several (or many) laser beams can be shone so their paths intersect, but there is no interference among the beams, even when they are confined essentially to two dimensions. Electric currents must be guided around each other, and this makes three-dimensional wiring necessary. Thus, an optical computer, besides being much faster than an electronic one, might also be smaller.
Some engineers think optical computing will someday be common, but most agree that transitions will occur in specialized areas one at a time. Some optical integrated circuits have been designed and manufactured. (At least one complete, although rather large, computer has been built using optical circuits.) Three-dimensional, full-motion video can be transmitted along a bundle of fibers by breaking the image into voxels. Some optical devices can be controlled by electronic currents, even though the impulses carrying the data are visible light or IR. Read the rest of this entry »
Motherboard
The motherboard is the “body”of the computer. Components directly attached to the motherboard include:
The central processing unit (CPU) performs most of the calculations which enable a computer to function, and is sometimes referred to as the “brain” of the computer. It is usually cooled by a heat sink and fan.
The chipset mediates communication between the CPU and the other components of the system, including main memory.
RAM Stores all running processes (applications) and the current running OS. RAM Stands for Random Access Memory
The BIOS includes boot firmware and power management. The Basic Input Output System tasks are handled by operating system drivers.
Internal Buses connect the CPU to various internal components and to expansion cards for graphics and sound. Read the rest of this entry »

The IBM 5100 Portable Computer was a desktop computer introduced in September 1975, six years before the IBM PC. It was the evolution of a prototype called the SCAMP (Special Computer APL Machine Portable) that IBM demonstrated in 1973. In January 1978 IBM announced the IBM 5110, its larger cousin. The 5100 was withdrawn in March 1982.
When the PC was introduced in 1981, it was originally designated as the IBM 5150, putting it in the “5100″ series, though its architecture wasn’t directly descended from the IBM 5100. Read the rest of this entry »
