When considering computer prices‚ people also must factor in the price of virus protection software when buying a PC. "Security concerns have long been an issue with Microsoft products. Windows XP has been criticized for its susceptibility to buffer overflows‚ malware‚ viruses‚ trojan horses‚ and worms" (Criticism‚ 2007). For people who have had virus problems or had their computers destroyed by viruses‚ Macs might seem like the obvious choice. PCs do have an advantage when it comes to being the

Many intrusion prevention systems can learn normal application and network behavior to block bad activities‚ like a file trying to infect a system‚ or a worm getting through application vulnerability and launch a buffer-overflow (Hulme‚ 2004).

Research Assignment‚ Part One Brandon Kelly IT221 - E-2 Fall 2011 Instructor: Stephen Todd 12-17-2011 Question 1 - Why does Windows Server 2008 come in different versions? What is the significance of each version? Most editions of Windows Server 2008 are available in x86-64 and IA-32 versions. Windows Server 2008 for Itanium-based Systems supports IA-64 processors. Microsoft has optimized the IA-64 version for high-workload scenarios like database servers and Line of Business (LOB)

used on widows-based computers as a default file sharing protocol. SMB supports: * “Sending multiple SMB commands within the same packet. This reduces the number of packets sent between an SMB client and server. * Much larger buffer sizes compared to SMB 1.0. * Increases the restrictive constants within the protocol design to allow for scalability. Examples include an increase in the number of concurrent open file handles on the server and the number of file shares that
