Just run it and it'll connect you for FREE to the internet. It doesn't get easier than this.

The ideal WiFi-tool for frequent travellers and mobile professionals. Pocket WiFi Radar will connect to open hotspots and automatically get your email or start any program you want. All of that in a cool animated radar screen. You may walk around and it will keep scanning untill it finds a free internet connection for you. It plays a sound and opens your webbrowser as soons as it succesfully finds a open, unsecured access point. But you may also use it to connect to your WEP-secured access point.

Network adapter

 A network adapter interfaces a computer to a network. The term "adapter" was popularized originally by Ethernet add-in cards for PCs.

Modern network adapter hardware exists in several forms. Besides traditional PCI Ethernet cards, some network adapters are PCMCIA devices (also know as "credit card" or "PC Card" adapters) or USB devices. Some wireless network adapter gear for laptop computers are integrated circuit chips pre-installed inside the computer.

Windows and other operating systems support both wired and wireless network adapters through a piece of software called a "device driver." Network drivers allow application software to communicate with the adapter hardware. Network device drivers are often installed automatically when adapter hardware is first powered on.

A few network adapters are purely software packages that simulate the functions of a network card. These so-called virtual adapters are especially common in virtual private networking (VPN).

Motherboard

The motherboard is the main circuit board inside your PC. Every components at some point communicates through the motherboard, either by directly plugging into it or by communicating through one of the motherboards ports. The motherboard is one big communication highway. Its purpose inside your PC is to provide a platform for all the other components and peripherals to talk to each other.

GPS reciever for Computer/laptops

This GPS Receiver USB Adapter for Computers is a compact, accurate GPS receiver with low power consumption that plugs into your computer's USB port. This receiver is suitable for all the applications of a traditional GPS receiver including planning your trip before you head out or finding your location while you are camping. All you need is: (1) the GPS dongle; (2) a computer; (3) GPS navigation software**; and (4) a destination. After installing the receiver and the necessary software, you can find your location right on your laptop. The GPS receiver takes its power from the PC it is attached to, so there are no extra wires or cables to tie you down. 

Based on SiRF Star III chipset technology, the GPS receiver provides accurate GPS positioning within 1 to 5 meters. To ensure up-to-the-second accuracy, the receiver tracks up to 20 satellites at a time, re-acquires satellite signals in about 100 milliseconds and updates position data every second. Data output by this GPS receiver include: (1) latitude/longitude/altitude; (2) velocity; (3) date/time; and (4) satellite and receiver status. An internal rechargeable Lithium-ion battery sustains the internal clock and memory and is recharged during normal operation. Its compact design is ideal for applications with space limitations.

BIOS chip

  

 The BIOS is short for Basic Input / Output System. By definition, it is the interface between software and hardware which allows software and hardware to communicate and interact with each other.

The BIOS  actually comprises of everything that allows software and hardware to interact with each other. While you may think that the BIOS only exists in the form of the motherboard BIOS, it is actually the combination of the motherboard BIOS, the BIOS of all add-on cards in the system as well as their device drivers.

Although, by definition, the BIOS consists of the motherboard BIOS, the BIOS of all add-on cards in the system as well as their drivers, we will be concentrating on the motherboard BIOS in this guide.

The motherboard BIOS is the most important component of the BIOS layer. That is because it contains all the software that is needed to get the computer started. It also comes with basic diagnostics and utilities.

 The motherboard BIOS is stored in a chip on the motherboard. The BIOS chip normally comes in the form of a rectangular DIP (Dual In-line Package) or a square PLCC (Plastic Leaded Chip Carrier) package.

The capacity of BIOS chips is measured in Megabits. Most BIOS chips these days are 2Mbits (256KB) in size. These higher capacity chips allow the manufacturer to offer more features than is possible with the smaller 1Mbit chips.

But note that the size of the BIOS chip has nothing to do with its performance. The choice of type and size of the BIOS chip is a matter of economics and requirements.

Active Pixel Sensors (CMOS Sensor)

CMOS (Complimentary Metal Oxide Semiconductor) sensors or Active Pixel sensors were first discussed in length in a paper from Dr. Eric Fossum, a scientist at NASA’s Jet Propulsion Laboratory, in 1992. 1993 through to 1995, JPL developed much of the technology which would be implemented into the CMOS sensor. Fossum and other members of the JPL co-founded Photobit Corporation in 1995 to commercialize the technologies they had developed. In 2001, Micron Technology acquired Photobit and used its extensive knowledge of CMOS wafer manufacturing to enhance the development further.
CMOS sensors derive their name from the way they are manufactured. They are cut from a CMOS wafer which is cheaper to produce then a CCD wafer, provides less power consumption, and also allow for more involved circuitry along side of the photosite array. Each photosite in the CMOS sensor has three or more transistors which has its benefits and its draw backs. The transistors allow for processing to be done right at the photosite, and each pixel/photosite can be accessed independently. Because the transistors occupy space on the array, some of the incoming light hits the transistors and not the photosites, which leads to picture noise. CMOS sensors also function at a very low gain which may contribute to noise.

PCI Slots and AGP Slot

These expansion slots represent 32-bit PCI Local Bus slots. All the PCI slots accept PCI bus mastering cards and fully support the PCI 2.1 specification. Because of the ATX form factor, all slots accept full-length cards.

This motherboard contains a shared PCI/ISA expansion slot. Only one of these slots may be used at one time by a plug-in card. Accelerated graphics port (AGP) The AGP is a high-performance interconnect for graphic-intensive applications, such as 3D applications. AGP is independent of the PCI bus and is intended for exclusive use with graphical-display devices. AGP provides these performance features: Pipelined-memory read and write operations that hide memory access latency Demultiplexing of address and data on the bus for near 100 percent bus efficiency AC timing for 133-megahertz (MHz) data transfer rates, allowing data throughput of 500 megabytes per second AGP complies with the 66 MHz PCI specification.
