In summary, the conversation is about using Hamming code to detect and correct single bit errors. The first question asks to convert a 7-bit binary code into a suitable Hamming code with EVEN parity. The second question involves retrieving a symbol using Hamming code and determining the original stored symbol if a 1-bit error occurred. The person is seeking help and asking for any insight or attempts from others.

Hey Guys, I can't rap my head around these questions. I'm not to sure how to begin them. Any insight would help.


1) Convert the 7-bit binary code 011 1101 into a suitable Hamming code that can detect and correct a single bit error. Use EVEN parity. Write your final answer as a 3-digit hexadecimal.2) When using Hamming code with EVEN parity for 7-bit ASCII characters, the following symbol is retrieved:
01100110101

Assuming a 1-bit error, what was the original stored symbol? Write down your answer as a 7-bit binary, with no spaces.

1. What is the difference between a processor and memory?

A processor is the central unit of a computer that performs calculations and executes instructions. Memory, on the other hand, refers to the storage space where data and instructions are temporarily held for processing by the processor.

2. How does a processor access memory?

A processor accesses memory through the use of a memory address, which is a unique identifier for a specific location in memory. The processor sends the address to the memory controller, which retrieves the data from that location and sends it back to the processor.

3. What is the role of cache memory in processors?

Cache memory is a small amount of high-speed memory that is located on the processor chip. Its primary role is to store frequently used data and instructions for quick access, which helps improve the overall performance of the processor.

4. How do processors and memory affect a computer's performance?

The processor and memory are two of the most crucial components that determine a computer's performance. A faster processor can perform calculations and execute instructions more quickly, while more memory allows for more data and instructions to be stored and accessed simultaneously.

5. Can processors and memory be upgraded?

Yes, processors and memory can be upgraded in most computers. However, it is important to check for compatibility and ensure that the new components are supported by the motherboard before making any upgrades.
