251.	Data stored in an electronic memory cell can be accessed at random and on demand using __________(a) Memory addressing(b) Direct addressing(c) Indirect addressing(d) Control UnitI got this question by my school principal while I was bunking the class.This intriguing question comes from Introduction of Memory Devices in chapter Memory Devices of Digital Circuits
Answer» Correct option is (b) Direct addressing Explanation: Direct addressing ELIMINATES the need to PROCESS a large stream of irrelevant data in ORDER to the DESIRED data word.

252.	CD-ROM refers to __________(a) Floppy disk(b) Compact Disk-Read Only Memory(c) Compressed Disk-Read Only Memory(d) Compressed Disk- Random Access MemoryI got this question in my homework.The above asked question is from Introduction of Memory Devices in section Memory Devices of Digital Circuits
Answer» The correct choice is (B) COMPACT Disk-Read Only MEMORY The EXPLANATION: CD-ROM refers to Compact Disk-Read Only Memory.

253.	VLSI chip utilizes __________(a) NMOS(b) CMOS(c) BJT(d) All of the MentionedI had been asked this question during an online exam.I want to ask this question from Introduction of Memory Devices topic in division Memory Devices of Digital Circuits
Answer» Correct option is (d) All of the Mentioned For explanation: VLSI (Very Large Scale INTEGRATION) is a memory chip which is MADE up of NMOS, CMOS, BJT, and BiCMOS. It can include 10,000 to 100,000 gates per IC.

254.	A large memory is compressed into a small one by using __________(a) LSI semiconductor(b) VLSI semiconductor(c) CDR semiconductor(d) SSI semiconductorThe question was asked by my college director while I was bunking the class.My query is from Introduction of Memory Devices topic in portion Memory Devices of Digital Circuits
Answer» The correct ANSWER is (B) VLSI semiconductor To explain: VLSI (Very Large Scale INTEGRATION) semiconductor is USED in modern computers to short the SIZE of memory.

255.	Which one of the following has capability to store data in extremely high densities?(a) Register(b) Capacitor(c) Semiconductor(d) Flip-FlopI had been asked this question in an interview for internship.The doubt is from Introduction of Memory Devices in division Memory Devices of Digital Circuits
Answer» RIGHT answer is (C) Semiconductor Explanation: Semiconductor has CAPABILITY to store data in EXTREMELY high densities.

256.	A register file holds __________(a) A large number of word of information(b) A small number of word of information(c) A large number of programs(d) A modest number of words of informationThis question was addressed to me by my college director while I was bunking the class.The query is from Introduction of Memory Devices topic in portion Memory Devices of Digital Circuits
Answer» Correct answer is (d) A modest number of WORDS of INFORMATION Explanation: A REGISTER FILE is different from a simple register because of capability to hold a modest number of words of information. A word is a GROUP of 16-bits or 2-bytes.

257.	A register is able to hold __________(a) Data(b) Word(c) Nibble(d) Both data and wordI have been asked this question in class test.My question comes from Introduction of Memory Devices topic in section Memory Devices of Digital Circuits
Answer» Correct choice is (b) WORD To ELABORATE: REGISTER is also a PART of memory inside a computer. It stands there to hold a word. A word is a group of 16-bits or 2-bytes.

258.	A flip flop stores __________(a) 10 bit of information(b) 1 bit of information(c) 2 bit of information(d) 3-bit informationThe question was posed to me during an interview.The origin of the question is Introduction of Memory Devices topic in portion Memory Devices of Digital Circuits
Answer» Right answer is (B) 1 bit of information Easy explanation: A flip-flop has capability to STORE 1 bit of information. It can be used further after ERASING PREVIOUS information.

259.	The instruction used in a program for executing them is stored in the __________(a) CPU(b) Control Unit(c) Memory(d) MicroprocessorThis question was posed to me by my school principal while I was bunking the class.I would like to ask this question from Introduction of Memory Devices in division Memory Devices of Digital Circuits
Answer» The correct option is (c) Memory The EXPLANATION: All of the program and the INSTRUCTIONS are stored in the memory. The processor FETCHES it as and when required.

260.	Memory is a/an ___________(a) Device to collect data from other computer(b) Block of data to keep data separately(c) Indispensable part of computer(d) Device to connect through all over the worldI got this question in unit test.I'm obligated to ask this question of Introduction of Memory Devices topic in division Memory Devices of Digital Circuits
Answer» CORRECT answer is (c) Indispensable part of COMPUTER To elaborate: Memory is an indispensable unit of a computer and microprocessor based systems which STORES PERMANENT or temporary DATA.
