A hypervisor is a virtualization technique that runs multiple operating systems on the device. While non-hypervisor virtualization techniques run multiple operating systems on domestic computers and hand-held devices, hypervisors are used exclusively on devices whose sole task is to run multiple guest operating systems for commercial or industrial purposes. Hypervisors are used in gaming technologies, commercial servers, and malware systems. They are effective at reducing system requirements by running simultaneous virtual systems on the same hardware and sharing that hardware’s resources. How Hypervisors Work Hypervisors mimic operating systems by running Read More

DDR SDRAM is Double Data Rate SDRAM. DDR SDRAM is an improvement over regular SDRAM, also known as SDR SDRAM (Single Data Rate SDRAM). DDR SDRAM doubles the bandwidth of SDR DRAM by transferring data twice per cycle on both edges of the clock signal, implementing burst mode data transfer. DDR SDRAM is being supplanted by DDR2 SDRAM. Standard DDR SDRAM DIMM's DDR SDRAM is normally packaged in DIMM modules. DIMM Module Chip Type Clock Speed Data Rate Transfer Rate PC1600 DDR200 100 200 1,600 PC2100 DDR266 133 266 2,133 Read More
