The one with 1GB of RAM.
512MB is 0.5 of 1GB
Considering relative size, yes.
Most computer users will be happy with a 1 gigaHertz processor with between 512 megabytes and 1 gigabyte of Random Access Memory on the motherboard. This is more than adequate for almost all applications.
512 x 1024 bytes
This means the processor runs at a frequency of 1.85 gigahertz. In other words (ie.) the processor's instruction counter increments 1.85 billion times per second. If we assume that this is measured in megabytes (ie. 512 MB of RAM) then the computer has 0.5 gigabytes of memory. The memory of a computer is the amount of RAM it has. Notice that the amount memory is normally a multiple of two. A gigabyte of RAM ( 1 GB ) amounts to 1024 megabytes (1024 MB) of memory.
Many people mistake storage space for memory. Storage space is usually on a hard drive and can be very large. It is measured in terabytes and gigabytes. 1000 gigabytes equals 1 terabyte. Memory is use by a computer to run programs and the operating system for the computer itself. This type of memory is usually called RAM or Random Access Memory. They are usually measured in gigabytes and megabytes. 1000 megabytes equals a gigabyte. Make sure you are comparing the correct type of "memory." Is it for storage or for running the computer? To take your question at face value, 0.99 gigabytes is much larger than 512 megabytes. 0.99 gb = 990000 mb, so 512 mb would be very small.
You can personalize the Inspiron 546 MT to include as much or as little memory as you like,but 512 mb is standard?
1 GB is 1024 MB (possibly only 1000 MB) and therefore is more.
1GB has way more memory. 1GB is 1000 MB. so 512 MB is about half of 1GB
In theory it will run faster with the 512Mb stick, as the computer only needs to send and receive date from one source, as opposed to two, which takes more system resources (regardless of the memory size of the two sticks).
512 mb
I'm not sure what currency you are using. US dollars? No. Rupees? Heck, yes!
The address of the last byte in a 512 mega byte memory, expressed as a decimal number, is 536,870,911.
