a. Given the logical address 0x 69656, what will be the logical page number issued by a process P?  b. What is the corresponding physical frame number?  c. What is the hexadecimal physical address?    Note: Your responses should be given in hexadecimal format!

Suppose a file of 10,000 bytes is to be sent over a line at 2400 bps. A. Calculate the overhead in bits and time in using asynchronous communication. Assume one start bit and a stop element of length one bit, and 8 bits to send the byte itself for each character. The 8-bit character consists of all data bits, with no parity bit. B. Calculate the overhead in bits and time using synchronous communication. Assume that the data are sent in frames. Each frame consists of 1000 characters = 8000 bits and an overhead of 48 control bits per frame. C. What would the answers to parts (a) and (b) be for a file of 100,000 characters?

Assembly

A segment at an absolute address like 40h must be defined in some way.

The names of the addressing modes that are not allowed for destination, together with the justifications for this, are mentioned in MC68000.

Suppose a computer system uses 16 but addresses for both virtual and physical address. In addition, assume each page (and frame) has a size of 256 bytes. -How many bits are used for page number? -How many bits for offset? -what is the max number of pages a process can have?
