What is bus cycle in a microprocessor?
Bus cycle is a single transaction between the main memory and the CPU.
If you were able to look inside a RAM stick, it would look like at spreadsheet. 8 columns across (8 bits) and billions of rows long depending on the side of the RAM. So 1 bit is 1 character, eight bits is a word or 1 byte.
What is the capacity of DRAM with twelve address lines?
Since DRAM uses address multiplexing(essentially each line accesses both columns and rows in memory) you need to take 2 to the 24th power to find your total capacity(basically doubling the number of address lines). In this case it would be 16,777,216.
What is the difference between microprocessors and CPUs?
Another Answer
The CPU (Central Processing Unit) is the core of any computer, while the microprocessor refers to the whole functional chip that is inserted into a motherboard. The CPU is the sub architecture of the microprocessor that interprets the program instructions and cascade triggers the sub-functions of each instruction.
What do you mean by multiplexing the bus?
If you have less no of data than the no of bits of data or address to b transfer Multiplexing mean to manage given busses in such a way that data or address can be transferred perfectly
What is meant by latching in microprocessors?
It is the time period in the clock cycle in which the signal on the bus must be the valid expected data. ie. The stable period of the data transmission that will then be loaded into the microprocessor as the actual data.

What is an explanation of the 8288 Bus controller?
inteT 8288 BUS CONTROLLER FOR iAPX 86, 88 PROCESSORS Bipolar Drive Capability Provides , The Intel"' 8288 Bus Controller is a 20-pin bipolar component for use with medium-to-large iAPX 86, 88 , ). ÂËN I Address Enable: AEN enables command outputs of the 8288 Bus Controller at least 115ns after , of two ways dependent on the mode of the 8288 Bus Controller. I/O Bus Mode - The 8288 is in the I/O , no arbitration is present. This mode allows one 8288 Bus Controller to handle two external busses. No ... OCR Scan

What is the importance of an internal data bus?
Buses are just conductors to carry data from one place to another place in terms of microprocessor from one register to another register.

Is physical address the home address?
Yes, a physical address would the the same as a person's address of their home. An example of a non-physical address would be a PO Box address.
That isn't exactly a question, but if it were, the answer would be "true".
What does the number of bits used to represent a memory address determine?
The number of bits used to represent a memory address determines the number of different addresses that can be formed. If the number of bits is N, then 2N addresses can be formed.
Note that the amount of addressable memory is not the same as the amount of physical memory. As addressability goes up, often physical memory does not match it, which means that effective addressability is limited.
Write a sequence of instruction to exchange two register contents using stack in 8086 processor?
To exchange two registers, say the BX and CX registers, in the 8086 using the stack, you can use...
PUSH BX
PUSH CX
POP BX
POP CX
... Of course, this is for 16 bit operation. If you want 8 bit operation, you will need to do more than that, because stack operations are always 16-bit operations.
How do you know the starting and ending address of E000H in segment register?
The starting and ending addresses of segment E000H is E0000H and EFFFFH.
How do you register for the series 63 exam?
First, you need to check some requirements you need to fulfill that will comply to FINRA's(Financial Industry Regulatory Authority) requirements and then after that find an approved and accredited series 63 licensing exam provider online or in a local school. You can also try to take a preparatory course that will help you to easily pass the actual series 63 license exam.
