Motherboard

The Motherboard is indeed the largest circuit card inyour computer.All components are attached to yourmotherboard either directly or indirectly.

In 1982,IBM or International Business Machines made theoriginal PC motherboard which used the 8088 CPU orCentral Processing Unit.This simple board also had a BIOS,memory sockets and adapter slots.

The Motherboard have several formats with the Baby ATbeing the classic format for 486 and Pentium computers.The ATX format comes with the Socket 7 and Slot 1 mainboard while the new NLX motherboard is considered lowcost with PCI and ISA slots mounted on raisers.

The Motherboard's form factor is its physical size andshape.The form facter measurement for motherboardsare from the outside dimensions.We will look at the Pentium Motherboard in and out of the case.

Let's take the time to look at the components of the motherboard and how they relate to each other.We willlook at the Titan 3 Gigabyte Pentium 4 Motherboard andits components.

COMPONENTS ON THE MOTHERBOARD

CPU Chip is the brains of any computer.This Pentium 42.5 gigabyte chips has a very large cooling fan whichcirculates air around the chip.

RAM Memory is where information is stored for very quick access by the computer.DIMM memory was the popularmemory chip until the more recent RIMM Chips came onthe scene.

BIOS Chip is that chip responsible for holding the datathe computer needs to start and to check all devices inthe system.This data is not lost when the computer isturned off.The cmos battery keeps the data intact.

CMOS Battery provides power to the BIOS Chip so thatthe computer can access the data on the chip.This dataallows the computer to boot up.

ISA Slots stands for Industry Standard Architecture andthis is the older and slower data bus used on 486 PCs.

PCI Slots replaced the slower ISA Slots.The PCI data bus gives the computer much faster data transfer fromthe device to the motherboard.

AGP Slot is used by the video card to provide quickand fast access by the cpu.Video data is send directlyto the cpu without any delay whatsoever.AGP stands forAccelerated Graphics Port: an Intel-designed 32-bit PC bus architecture introduced in 1997 allowing graphics cards direct access to the system bus.

USB Ports or Universal Serial Bus ports are Intel's newerstandard connection for attaching such peripherals asdigital cameras.

PCB

A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, or traces, etched from copper sheets laminated onto a non-conductive substrate. It is also referred to as printed wiring board (PWB) or etched wiring board. A PCB populated with electronic components is a printed circuit assembly (PCA), also known as a printed circuit board assembly (PCBA).

PCBs are rugged, inexpensive, and can be highly reliable. They require much more layout effort and higher initial cost than either wire-wrapped or point-to-point constructed circuits, but are much cheaper and faster for high-volume production. Much of the electronics industry's PCB design, assembly, and quality control needs are set by standards that are published by the IPC organization.

Finding Great AdSense Keywords

When someone asks "What are good AdSense keywords?" they are really asking about the best keywords to optimize their pages with which have AdSense ads on them. Success with AdSense is all about driving traffic to niche websites. The chosen keywords to optimize the site's pages with will make or break efforts to earn income from Adsense. Success requires choosing a niche area without too much competition. Yet, the niche must have enough interest to insure there are sufficient numbers of searches. Many people choose niches which are simply too competitive to ever have a chance of being ranked on the first page of search engine results.

This is the most common mistake made when creating AdSense sites.

AdSense keywords for a given niche must allow the site owner to rank his or her pages on the first or second pages of Google and/or Yahoo search result pages. The best way to find these AdSense keywords is to brainstorm with the many free keyword tools available online. I have found even the free versions to be of great help for discovering AdSense keywords which can be used to optimize pages with. I particularly like the Google keyword tool. Simply do a search for "keyword tool" in Google and it is usually the first result.

When you find possible keywords, they should be checked in a Google search with quotes around them. Notice the number of total sites with that keyword in the content. For example, if there are 500,000 other sites with that keyword, it is probably too competitive of term for you to ever get traction with. On the other hand, if the AdSense keyword shows only 5,000 other sites, it can be very easy to rank well in the search engines.
