Graded Discussion Board
Dated:Dec 21, 22
Dear Students,
The graded Discussion Board (GDB) of CS101
has been posted on VULMS in GDB Section. The discussion will be opened from
27th December 2022, 12:00 AM, and will remain open for the next 48 hours (02
days -- on 27th December and 28th December 2022). You can participate in the
discussion during these 2 days on the 27th and 28th December.
GDB problem Statement:
In a computer system, all software including
the operating system are installed in the secondary storage disk such as a hard
disk or SSD. For the execution purpose, a software is loaded from secondary
storage into the main memory (RAM). However, the installation size of some of
the software is more than the capacity of the RAM and they cannot be loaded
into the RAM completely. In such a case, a solution might be to execute such
software directly from the secondary storage instead of loading it into the RAM
for execution.
Do you recommend that such a large software can
be executed directly from the secondary storage, especially if we use
relatively fast SSD storage?
Justify your answer with proper reasons in
either case (support/against). Your answer should not be more than 6 to 8
lines.
Instructions:
1. Your answer must be relevant and precise, as
long and irrelevant answer will lead to deduction of your marks.
2. You need to use font style as “Times New
Roman” and font size as “12”.
3. You need to write your answer by your own.
Copying form Internet or any other sources will be awarded zero marks.
4. You should post or submit your answer on the
Graded Discussion Board (GDB), not on the Moderated Discussion Board (MDB).
5. You can’t participate in the GDB after the
due date via email.
Answer
GDB
No,
1. Random
Access Memory, or RAM, keeps computer software applications running while they
are working.
2. Because
the CPU is unable to execute directly from the hard disk, even if the tens of
millions of times slower performance was tolerable, it is simply not possible
to do so. Additionally, loading the entire program before beginning execution
would cause excessive delay in the beginning
3. A CPU or
processor cannot directly access secondary memory. The operating system loads
any process into primary memory, which is smaller and can be directly accessed
by the CPU in order to execute it.
4. Since
there is no software in the main memory of a computer's central processing unit
(CPU), a process must load software into memory before it can be run
5. The
Central Processing Unit (CPU) does not directly access secondary memory.
Instead, data accessed from a secondary memory is first loaded into RAM before
being sent to Processing
6. Code
cannot be executed by the processor unless it is in memory space that can be
addressed by the processor (i.e. a RAM or ROM) Since the processor cannot
address a hard disk, programs cannot be run without first being loaded into
RAM.
