As the title says I have been taking an A+ course at my school. The certification will garuntee me a job at geek squad (amongst other places), and will certainly help me get a job at higher paying jobs.
Here is what I have learned so far (That I can remember):
-In the beginning of the PC era they made the speed of the CPU slower, and added lesser amounts of ram RAM delibrately.
-RAM was integrated directly into the motherboard in the early PC era.
-Before Zero Insertion Force sockets were introduced, there were slot sockets that the CPU "snapped" into.
-CMOS, or "Complementary Metal-Oxide Semiconductor", carries the fundemental Data for booting the computer.
-CMOS is battery powered, and the battery can last for years as the CMOS requires very little power to keep its data, unlike RAM which loses its data after the computer is turned off.
-SDRAM is Static Dynamic Random Access Memory, often referred to as Single Data Rate, this is because there is only one channel for the data to flow (To the memory, or to the computer). This can be very slow to get the job done.
-DDRRAM is Double Data Rate, so named for the Dual Channels for data to flow.
-RDRAM is the more advanced cousin of DDRRAM, it has not been adopted as widely as DDRRAM because of a high liscensing fee.
-ISA or Industry Stanard Arcitecture was very advanced in the beginning, but grew seriously outdated. Several attempts were made to revise and improve ISA, but they were flawed.
-PCI or Peripheral Component Interface addressed these problems and more, boosting the speed the expansion cards would operate at, and the slots are still in use today.
-PCIe is the faster upgraded version of PCI, and are becoming more common in computers.
Keep in mind these are fun facts that my teacher says would be good to memorize. There were also questions on practical real life applications, and i usually get around 80-100% right.
