2. Computer Issues/Problems
1.Computer Starvation – is a
problem that continuously
denies necessary resources
for processes to work
causing decreasing the
computer process.

3. Computer Issues/Problems
2. Speculative Execution –
it may totally halt the
computer processes as stops
the entire CPU until an issue
is resolved.

4. Possible Solutions
1. Starvation
• Aging is a technique where
the priority of the processes is
incrementally increased in the
system for a long time.

5. Possible Solutions
2. Speculative Execution –
ensuring that instructions are
executed only when the
control flow leading to them is
ascertained would prevent
speculative execution.

6. Possible Solutions
2. Speculative Execution – the
software could be modified to
use serializing or speculation
blocking instructions that
ensure that instructions
following them are not
executed speculatively.
