Explain the Statements Present in Assembly Language
An assembly program consists of subsequent three types of statements:
a. Imperative statements: this point out an action to be carried out during execution of the assembled program. Every imperative statement usually translates into one machine instruction.
b. Declaration statements: The syntax of declaration statements is like this:
[Label] DS [Label] DC ‘’
The DS statement reserves areas of memory and links names with them. The DC statement constructs memory words containing constants.
c. Assembler directives: These instruct the assembler to carry out specific actions during the assembly of a program. For instance START directive points out that the first word of the target program generated by the assembler should be placed in the memory word along with address .
Facilities of a Debug Monitor Facilities of a debug monitor are like this: Setting breakpoints in the program Initiating a debug conversation while control reaches
Can a direct access file be read sequentially? Explain. Yes. Keep a counter, cp, initially set to 0. After reading record cp, increment cp.

Deadlocks can be detected while the program is running, by running cycle detection algorithms on the graph that de?nes the current use of resources. De?ne this graph as follows:
Identifying parallelism A formal way to identify parallelism in an activity is to draw a task dependence graph in a directed graph in which each vertex represents a task to
Define deadlock avoidance. An alternative method for avoiding deadlocks is to need additional information about how resources are to be requested. Every request requires the sy
