FIRST QUIZ September 29, 2020 admin Leave a comment WELCOME TO THE CAO EC8552 I UNIT ONLINE QUIZ Your Name Your Email What Characteristics of RAM memory makes it not suitable for permanent storage? too slow unreliable it is volatile too bulky Computer use addressing mode techniques for? giving programming versality to the user by providing facilities as pointers to memory counters for loop control to reduce no of bits in the field of instruction specifiying rules for modifying or interpreting address field of the instruction All the above The addressing modes, which uses the PC instead of a general purpose register is? Indexed with offset Relative Direct Both Indexed with offset and direct The addressing mode which makes use of in-direction pointers is? Indirect addressing mode Index addressing mode Relative addressing mode Offset addressing mode The addressing mode, where you directly specify the operand value is? Immediate Direct Definite Relative Which addressing mode is most suitable to change the normal sequence of execution of instructions? Relative Indirect Index with Offset Immediate The CISC stands for? Computer Instruction Set Compliment Complete Instruction Set Compliment Computer Indexed Set Components Complex Instruction set computer The computer architecture aimed at reducing the time of execution of instructions is? CISC RISC ISA ANNA The RISC processor has a more complicated design than CISC? TRUE FALSE Pipe-lining is a unique feature of ? RISC CISC ISA IANA Which addressing mode execute its instructions within CPU without the necessity of reference memory for operands? Implied Mode Immediate Mode Direct Mode Register Mode Which register holds the address for a stack whose value is supposed to be directed at the topmost position? Stack Pointer Stack Register Program Counter None of the above The instructions based on the stack operations are also known as 'zero address' or 'implied instructions', because? address gets updated automatically in stack pointer processor can refer a memory stack without specifying the address both a & b none of the above When necessary, the results are transferred from the CPU to the Main Memory by? I/O Devices CPU Shift Registers none of these In which addressing mode the operand is given explicitly in the instruction? Absolute Immediate Indirect Direct A collection of lines that connects several devices is called? Bus Peripheral connection wires Control unit Internal wires The most common addressing technique employed by the CPU? Immediate Direct Indirect Register CPU does not perform the following operation? Data transfer Logic operation Arithmetic operation All of above Which of the following memories must be refreshed many times per second? Static RAM Dynamic RAM EPROM ROM Which of the following is the address generated by the CPU? Physical address Absoluted address Logical address None of the above . What does the symbol '#' represent in the instruction MOV A, #55H ? Direct datatype Indirect datatype Immediate datatype Indexed datatype The addressing mode used in an instruction of the form ADD X, Y, is? absolute immediate indirect Relative In the absolute addressing mode? Operand is inside the instruction Address of the operand is outside the instruction Register containing the address of the operand is speciied inside theinstruction Location of the operand is implicit The CPU of a Computer takes instruction from the memory and executes them. This process is called? Load cycle Time sequence Fetch-execute cycle None of these The ALU of a computer normally contains a number of high speed storage elements called? Semi conductor memory Registers Hard disk IC Time is Up!
