What is a Motherboard-_961

What is a Motherboard?

The motherboard is the backbone of any computer. It's the component around which everything else is built. The definition of a motherboard is a printed circuit board containing the slots for the CPU, RAM, PCI cards and chipsets. Physically, the motherboard is a square or rectangle circuit board that every other component either slots into Dell Inspiron 1501 battery, or connects on to.

Depending on the type of board it might also have a sound chip, a graphics chip Dell Inspiron 1501 battery, network ports gateway laptop batteries, wireless ports, USB and other connection ports, and will also contain the BIOS so it can use all of these features.

The circuit board provides electrical connections between cheap components in order for them to receive power and instructions. The different slots connect to each other in different ways depending on the role of the slot.

The chipset is replacement the collective term for two chips, Northbridge and Southbridge. The Northbridge connects the CPU to the high speed components like the RAM and graphics card. The shop Southbridge handles the slower connections like those to the PCI slots or IDE and SATA interfaces. The function of these chips is purely to manage data throughput to the component cheap devices.

Processing

When processing, the CPU talks to the Northbridge via the Front Side Bus (FSB), if the message is for the memory or charger graphics cards, Northbridge transmits them directly. If the message is for a slower component, the Northbridge transmits the message to the Southbridge which then passes it gateway along to the component in question. This process is repeated for every single instruction, whatever it might be.

The speed of the Front Side Bus is often used in new motherboard specifications. For example a motherboard might feature a FSB1333Mhz in its literature. This measurement is the theoretical effective rate of data transfer between store the CPU and the Northbridge. The faster the Front Side Bus, the faster the theoretical speed of the computer.

Added extras on a motherboard are referred to as compaq "Integrated Peripherals." These are things like built-in networking, USB controllers, on-board sound, on-board graphics and any other extra functionality the discount motherboard might have. These vary from model to model, but most modern motherboards will feature some if not all of these. These will all connect to the Southbridge and use it to acer aspire talk to the rest of the components.

So as we see, the definition of a motherboard is a printed circuit board which connects all the various components together in zxcsky09520 order for them to be able to communicate with the CPU and sometimes dell laptop batteries, each other.

The Good and Bad Sides of Smart Cards_2691

The Good and Bad Sides of Smart Cards Smart Cards: The Pro Side

One of the most basic benefits smart cards offer is convenience. Consider the simple transaction of paying road tolls. Without any technology involved, a traveller is required to bring his or her car to a complete halt, possibly wait in a line, and proceed to a booth to hand a ticket to the attendant who needs to verify the amount of the toll, collect cash from the driver, provide change if necessary, and allow the driver to proceed.

A smart card, particularly a contactless smart card that uses radio frequencies, doesn’t require the driver to stop, or in some states, even slow down.

Security is another big advantage. In government offices or similar buildings in need of high security, unauthorized access is curtailed by requiring identification at points of entry. This keeps information, property, and lives safer from potential intrusions.

The Con Side

Smart cards are small and light, which makes them conveneintly portable hp pavilion dv6000 Battery, but it also makes them susceptible to loss and theft. If a card is mishandled or misplaced, the technologies that provide security and convenience can instantly become a source of vulnerability and expense. In the case of building access, for example, if a card is lost and not reported Dell Vostro 1000 Battery, it can increase the chances of a security breach.

A far greater issue, however is privacy. Leaving a trail of digital tracks using separate cards for distinct purposes is of little consequence to the majority of people in most cases. A person may use one type of card to access public transportation, a key card to enter a building, a credit card for purchases, another for network authentication, and a health insurance identification card with access to electronic medical records.

For privacy advocates, the big problem begins with the idea of compiling all of an individual's personal records into one central database and using a single, universal smart card for all electronic transactions that require authentication. Consider the immigration reform proposal, which calls for the creation of a biometric, mandatory national ID card. Although it is intended not to include any personal information, a national ID smart card, in the wake of the Real ID Act of 2005, would set a precedent that privacy organizations acer laptop batteries, such as the American Civil Liberties Union (ACLU), are staunchly against.

Conclusion

As with any system dealing directly with personal information and assets, defining smart card technology pros and cons is a matter of determining benefits and risks. Specifically, the benefits are improvements in efficiency, convenience, and security. The risks are in the loss of personal privacy and control of sensitive information, and the potential for the misuse of information. As the use of smart cards becomes more prevalent over time, weighing the good aspects against the bad remains an ongoing process.

For further information, the Bright Hub article Understanding the Different Types of Smart Cards discusses the main technological and functional differences of smart cards.
