What is the difference between SIMM and DIMM?e. Explain the function of address bus and data bus

SIMM and DIMM are both types of computer memory, but they have several key differences:

1. SIMM stands for Single In-line Memory Module. It is an older type of memory module that has a single row of pins on its edge. SIMMs are typically installed in pairs because they can only carry 32 bits of data at a time.

2. DIMM stands for Dual In-line Memory Module. It is a newer type of memory module that has two rows of pins on its edge. DIMMs can carry 64 bits of data at a time, so they do not need to be installed in pairs.

The function of the address bus and data bus in a computer system is as follows:

1. Address Bus: The address bus is a type of computer bus that is used to specify the location of data in the computer's memory or even in other devices within the computer. Each line in the address bus carries a bit of the address - the more lines there are, the more addresses the system can handle.

2. Data Bus: The data bus, on the other hand, is the pathway used for the actual transfer of data. The size of a data bus is usually measured in bits, and it determines how much data can be sent at one time. The larger the data bus, the faster the data transfer.

In summary, the address bus is used to determine where data is to be sent or retrieved from, while the data bus is used to transfer the actual data.
