Main Memory (CpE3B - Operating System)

What is memory in a computer system?

• Memory is the network connection that allows data transfer.

• Memory in a computer system is the hardware that stores data and instructions for processing.

• Memory is the part of the computer that processes data.

• Memory is the software that runs applications.

True or False: The CPU retrieves instructions from memory.

• True

• False

• The CPU only processes data, not instructions.

• The CPU does not interact with memory.

What does address binding refer to?

• Address binding is the process of encrypting data in memory.

• Address binding refers to the allocation of CPU resources to processes.

• Address binding is the mapping of logical addresses to physical addresses in memory.

• Address binding is the technique of compressing memory usage.

True or False: Compile time binding generates relocatable code.

• True

• False

• Relocatable code is generated at runtime.

• Compile time binding always generates relocatable code.

What is the main advantage of load time binding?

• Faster execution time due to pre-compiled resources.

• Reduced memory usage by avoiding dynamic linking.

• Simplified code structure with static resource allocation.

• Increased flexibility and dynamic linking of resources at runtime.

True or False: Execution time binding requires no special hardware.

• True, but only for certain types of systems.

• False, it always needs advanced processors.

• True

• False, it requires specific hardware support.

Match the following types of address binding with their descriptions: 1. Compile time binding 2. Load time binding 3. Execution time binding

• 2: Load time binding - Fixed addresses at load time

• 3: Execution time binding - Addresses determined at compile time

• 1: Compile time binding - Addresses determined at runtime

• 1: Compile time binding - Fixed addresses at compile time, 2: Load time binding - Addresses determined at load time, 3: Execution time binding - Addresses determined at execution time.

True or False: Memory only interacts with a stream of memory addresses.

• Memory only stores static information.

• True

• Memory interacts only with data types.

• False

What does the CPU do after fetching operands?

• The CPU decodes and executes the instruction.

• The CPU stores the operands in memory.

• The CPU powers down to save energy.

• The CPU sends the operands to the GPU for processing.

True or False: Absolute code is generated by load time binding.

• Absolute code is generated by run time binding.

• Absolute code is generated by compile time binding.

• True

• False
