Why operating system must be loaded first into computer's memory?
Otherwise your computer will be very, very, very slow, as it is much quicker to read and write from RAM then it is to read and write from the hard drive.
What is a race condition in operating systems?
a situation in which multiple processes read and write a shared data item and the final result depends on the relative timing of their execution
Why did Ralph Emerson write the poem The Concord Hymn?
It was written in the memory of the men who fought and died for us during the revolutionary war , so that we could have freedom that we have today ,and also it was written in April 19, 1836
Why did Michael Rutledge's write Samuel's memory?
To remind people of the suffering American Indians endured on the Trail of Tears.
What are process states in operating system?
To put it in simple terms, we write our computer programs in a text file and when we execute this program, it becomes a process which performs all the tasks mentioned in the program. When a program is loaded into the memory and it becomes a process, it can be divided into four sections ─ stack, heap, text and data
Explain with a timing diagram memory read and write operation?
You can find examples of a timing diagram online. Finding an image might make it easier to see exactly what is needed.
A CPU with a 20 MHZ clock is connected to a memory unit whose access time is 40ns formulate a read and write timing diagram using READ strobe and WRITE strobe. include the address in the timing diagra?
To formulate a timing diagram for a CPU with a 20 MHz clock (period = 50 ns) connected to a memory unit with a 40 ns access time, the READ and WRITE strobes can be illustrated as follows: READ Operation: The CPU issues a READ strobe after placing the address on the address bus. The READ strobe remains active for the duration of the memory access time (40 ns), during which the data is available on the data bus. WRITE Operation: For a WRITE operation, the CPU places the address and data on the respective buses and then activates the WRITE strobe. The WRITE strobe remains active for 40 ns, allowing the memory unit to store the data. In both cases, the address is stable during the strobe period, initiating the memory operation, and the timing diagram would show the CPU clock cycles, with the strobe signals overlapping the corresponding access time.
What are the four modes of operation?
There are 4 operation basiclly done in micro processor 1.memory read 2.memory write 3.i/o read 4.i/o write
What is the timing diagram for CALL instruction?
18 T States. 6T States for Opcode fetch. 3 *2 T States for memory write(PC pushed to stack) 3*2 T States for memory read (New value of PC fetched from memory). Good Luck!!!
What is the memory write operation?
read/write permissions/privileges allow the user to read, append and delete records from your database tables, however it cannot alter / create / drop the tables and its structures.Read/write privileges are ideal for forums and production websites that don't require creation or alteration of table structures on its normal operations.
What are the four common mode of operation?
There are 4 operation basiclly done in micro processor 1.memory read 2.memory write 3.i/o read 4.i/o write
How does the microprocessor knows which operation to perform first read or write?
in any of the microprocessor include sequencer that sequencer send control signal to the memory and processor to do specific operation like read or write operation
What are the operation performed by MPU?
The basic operations performed by MPU are under as follows: (1)Memory Read (2)Memory Write (3)Input/Output Read (4)Input/Output Write
Which concept is called dereference?
Doing read or write operation in memory using the help of poniter is called dereference.
What is function of IO-M in 8085?
I/O and memory operations are differentiated by this status signal. When it is HIGH, I/O operation takes place and when LOW, memory operation takes place. This signal is combined with read/write in order yo generate I/O and memory control signals.
What is the measure of memory devices operating speed called?
Memory device operating speed is measured in cycle time which is the amount of time required for memory to perform read and write operation and return to its original state ready for next operaiton. Access time is another measure of memory speed which is only the time required for read operation or it is the time between data receiving (read operation) and the data becoming available at the memory output.
What is 8085 control lines?
The 8085 microprocessor has several control lines that manage its operations and facilitate communication with other components. Key control lines include the Memory Read (MRD), Memory Write (MWR), I/O Read (IRD), and I/O Write (IWD) signals, which control data flow between the CPU and memory or I/O devices. Additionally, the Status signals (S0, S1) help indicate the current operation of the processor. These control lines are essential for coordinating data transfer and ensuring proper timing in the system.
