Please help me with this Computer Organization and Architecture Choose The Right Alternative(s) questions, its important to solve all of them <3

Textbook: William Stallings Computer Organization and Architecture 8th Edition

Choose The Right Alternative(s) - you can choose more than one answer:-

1- Which of these operating system is multitask?

• DOS

• Unix

• Macintosh

• Windows

2- Superscalar technology implements

• Mechanisms to communicate register values

• Logic to determine true dependencies involving register values

• Simultaneously fetch multiple instructions

• Mechanisms to initiate multiple instructions in parallel

3- Different types of fragmentation exists:

• Dynamic fragmentation

• Internal fragmentation

• External fragmentation

• Data fragmentation

4- There are many instruction types among them we can cite:

• Data movement (I/O)

• Program flow control

• Data storage (main memory)

• Data processing

5- In CISC architecture,

• Register references require more bits

• More instructions require longer operation codes

• memory is expensive

• simple control unit

6- There are many types of operands that we can mention

• Data Transfer

• Conversion

• Arithmetic

• Logical Data

7- If the size of the register address is 32 bits and the size of the word is 16 bits, the size of the RAM will be:

• 8 GB

• 4 GB

• 16 GB

• 32 GB

8- When the size of memory increases

• The access time to this memory increases

• The price of this memory increases

• The price of this memory decreases

• The access time to this memory decreases

9- If the size of the register address is 32 bits and the size of the word is 8 bits, the size of the RAM will be:

• 4 MB

• 2 GB

• 4 KB

• 4 GB

10- There exist many kind of operating system that we can mention:

• multi-programming

• single program

• batch

• interactive

11- The swapping is a space to store process in:

• Cache

• Register

• hard disk

• RAM

12- The size of cache is greater than:

• Hard disk

• registers

• RAM
