Hardware Interview Questions and Answers
Question - 71 : - What Are The Different Types Of Ram?
Answer - 71 : -
SRAM, DRAM, VRAM, SGRAM, DDR-SDRAM etc….
Question - 72 : - Differentiate Sram And Dram?
Answer - 72 : -
SRAM
Static RAM stores each bit of data on six metal oxide semiconductor field effect transistors, or MOSFETs. SRAM is used in devices that require the fastest possible data access without requiring a high capacity. Some examples are CPU caches and buses, hard drive and router buffers and printers.
DRAM
Dynamic RAM stores data using a paired transistor and capacitor for each bit of data. Capacitors constantly leak electricity, which requires the memory controller to refresh the DRAM several times a second to maintain the data.
Question - 73 : - What Are The Different Dram Types?
Answer - 73 : -
FPMDRAM, EDO DRAM, SDRAM, RDRAM, DDR-SDRAM
Question - 74 : - What Is The Difference Between Ddr-i And Ddr-ii?
Answer - 74 : -
DDR2 is the successor to DDR RAM. DDR 2 incorporates several technological upgrades to computer system memory, as well as an enhanced data rate.DDR 2 is capable of achieving twice the data transfer rate of DDR-I memory because of its higher clock speed. It operates at a lower voltage than DDR-I as well: 1.8 volts instead of 2.5.
