The student should Copy and Paste the above into a Notepad or Word document and print it. Most of the terms below are not actually acronyms, but some are contractions, you should know what words were contracted to create the terms. Then go online and find what each acronym spells out and fill it in on the lines provided. The student should then read a few definitions of each term and write out a definition on the back of a 3x5 card with the acronym on the front of the card. Then practice by shuffling your cards, then spell each one out and then define it. Then flip to the next card. When the student can go through the deck without difficulty a large part of the final exam is in the bag!

----Start Copy and Paste----
bit - binary digit
bps - bits per second
bus - set of parallel wires that each carry a single place value binary bit of a binary number
byte - 8 bit binary number
cache - high speed memory that is used to read ahead and write behind to/from slower memory
chipset - set of chips on the motherboard that directly communicate with the CPU transfering
data to/from the CPU to the rest of the system codec - coder/decoder computer - anything that can input raw data, process the data and output information motherboard - the main circuit board of the PC holding the chipset and to which the CPU is
mounted power supply - the device in the PC that converts wall current AC into the low voltage DC
needed by the electronic chips of the PC's devices proprietary - unique design of the original equipment manufacturer that can only be replaced
by the same item from the same manufacturer protected mode - the native mode of the Intel x86 family processors after the 8088 in which
RAM is managed such that no application may directly address RAM outside of its alloted RAM
space register - location onboard the chip that numbers can be stored and modified (math and logic
operations can be performed on the numbers only in the registers) real mode - native mode of the Intel 8088 processor that treats all addressable RAM as a single
flat addressable RAM space (programs have direct access to each other unimpeded) ----End Copy and Paste----
