Walaa Ahmed Dawoud 1st year - Intro to CS ‫والء أحمد فاروق داود‬ ____________________________________________ Exercise 1 8. Why ROM is Read-only and not R & W? Because the information is burnt into the ROM chip at manufacturing time. Once data has been written into a ROM chip, it cannot be erased but you can read it. 9. Compare between RAM and HD? Ram: ▪ Volatile memory. ▪ Stores data temporarily while the CPU is processing. ▪ Allows fast read and write access to run programs and processes. HD (Hard Disk): ▪ Non volatile memory/ you can store and retrieve data randomly. ▪ Stores data and files long term. ▪ Slower read and write speeds, but has a medium capacity for storage. 10. Compare between EEPROM and EPROM? ▪ In EPROM, the information can be erased using a special PROM programmer. ▪ But EEPROM does not require ultraviolet light to erase its content. 11. Is Flash Memory a type of RAM or ROM? No. It's a special type of EEPROM that can be erased and reprogrammed. 12. Compare between EEPROM and Flash Memory? ▪ EEPROM cannot be erased. ▪ Flash memory can be erased 13. What is the capacity of HD that consists of 10 Heads, 1024 tracks, 1024 Sectors, and each sector is 1024 Bytes? 1024×1024×1024×10 = 10737418240 Bytes = 10 GB 14. Write your Family name by binary?
