CIS 3380 TEST #3 STUDY GUIDE This is a document for Computer Information System. The contribution to this document must be done by everyone to is on this page. I have listed the reading on this page and each reading will have multiple people to summarize the reading. After the reading complete, it is the job of everyone to read over the summary to edit any mistakes. The first input to the document is in Black Ink Any add-on to the summary is Blue Ink Any place that you are not sure is correct put in Red Ink Please have the document completed by 12 pm Sunday 1) Know the best definition of information Data that is perceived to be useful by the recipient 2) Identify illustrative examples of data and information Data-numbers or places, could have no meaning Information-that which is perceived to be useful by the recipient, anything that has been organized, categorized, and accessed, data converted into a meaningful and useful content 3) Differentiate the features of AI from other systems AI is designed to learn from experience 4) Identify the correct cognitive level of an interaction or instance Sending an email to Dr. Ploeger to ask for more direction on this question Response from Dr. Ploeger That would be the recipient. However, a scenario can be given in which the cognitive level is obvious ie George Lucas & "Star Wars". 5) Recognize the reason EBCDIC has numerous instances of sequential unassigned binary codes. According to test 2 #14- Why are there groups of blank unassigned characters in EBCDIC? This is a result of using the binary for only the numbers 0-9 in the right hand 4 bits of EBCDIC 6) Comprehend the purpose, value and function of the data and address bus The address bus determines the maximum size of memory. The address bus identifies the location in memory for data requested by the CPU. The data bus sends and receives data Data on the address bus is only sent from CPU to memory The maximum size of memory is determined by the address bus The address bus is used by the processor in a computer to locate a piece of data from the RAM (Random Access Memory) that it needs to access. No real data is carried via the address bus, as this is the job of the Data Bus. The pieces of data that the address bus locates are called "addresses" and the address bus

transfers "data addresses" to and from the control unit. 7) Know how data is represented inside of the computer Electric voltages 8) Recognize the steps used in fabricating semi-conductor chips on wafers Silicon wafers are fabricated into 12’’ discs A negative image laid over the wafer and the wafer then exposed to light (photo resist) The wafer is then placed into an acid bath that eats away at the areas exposed to light The wafer is baked This process is repeated until all the layers of circuitry are complete 9) Identify applications and technology associated with ROM, PROM, EPROM, EEPROM ROM - can only read from the memory PROM - Programmable Read Only Memory Chip - write the program and store it on the chip, there is a
