With the rapid development of computers and software, sometimes we as computer users are forced to continuously improve our computer. The standard specification of a computer 1 or 2 years ago probably is not valid anymore which is too slow to run new applications at this time.

Actually you can upgrade every part of your computer equipment instead of buying a new set of computer. Basically you can upgrade three important part that influence the speed and performance of computer, memory (RAM), graphic card (VGA), and processor (CPU). But most of users will install computer memory upgrade firstly because a memory upgrade is the least expensive among others to improve the performance of computers.

What Kind of Memory Does Your Computer Use?
Each computer has different hardware specification. The computers use certain memories according to slots provided by its motherboard. The slots provided also determine the maximum memory capacity you can add into your computer. more…

Right on 27-29 October, a number of world’s solution providers, consultants, board & system level vendors, equipment manufacturers, standardization bodies, analysts, software companies, computer OEMs, other companies, and partners (more than 100 participants) will meet together at AdvancedTCA Summit 2009 in Santa Clara, California. Some of participants such as Intel Corp, Cisco Systems, Kontron , Emerson Network Power, Sun Microsystems, Crystal Cube Consulting, etc. The Summit is about the use of AdvancedTCA as well as AdvancedMC and MicroTCA as the standard of choice for system designers and architects in developing the next generation networks with wireless-based systems implementation.

It is interesting that the AdvancedTCA standard-based implementation is successfully applied not only in telecom networks, but also in lab research operation, central office applications, medical services integration, and even for military infrastructure. Open standards-based AdvancedTCA is surely reliable to optimize packet-based telecom applications with its very small design, high scalability and flexibility more…

It is available for any vendors or companies that want to migrate and improve their proprietary telecommunication network or central office application server to open standard one. Introducing, Kontron Advanced Mezzanine Card (AMC, or PICMG AdvancedMC) Modules and Advanced Telecom Computing Architecture Boards (ATCA).

AMC (AdvancedMC) is the PCI Industrial Computer Manufacturers Group’s specification (PICMG AMC.0, AMC.1, AMC.2, AMC.3 and AMC.4 respectively) for hot-swappable FRUs (field replaceable units) and field-replaceable mezzanine cards, enabling them to be replaced individually in the field. It is more attractive by enhancing its scalability, flexibility, and upgradeability. By combining a general-purpose AdvancedTCA board with application-specific AdvancedMC modules, designers can create versatile telecom blades whose functionality and capacity can be upgraded without replacing the entire blade. more…

Firewall is an application installed on a computer or computer network and work to prevent them from piercing access interference from entitled outside parties. The firewall also works to protect the data that exists in a computer or computer network, protect from data theft or spying. All access activities that enter or exit in a network must be through this firewall. Firewalls also be used for detecting and monitoring all in out network data. Firewall tasks are monitoring and maintaining network elements such as source (the source of the data packet originated), destination, the protocol that is used and the content of the package the data itself.

So, the firewall can be used by Internet users to protect the network from interference outside parties with a way to block the transmission of data from a particular address, prevent the exchange of data between certain units of the computer, reject the package with certain contents of data, and prevent the using of certain protocols in data exchange. While some techniques on the firewall such as: more…
