BandwidthWhen referring to your own connection, bandwidth is the total maximum capacity of your network or modem connection. A MODEMs bandwidth is measured in BPS. The more bandwidth you have, the faster you will be able to receive and/or send information.
If bandwidth is being shared, you will likely not be able to reach the maximum capacity of the bandwidth when other computers, users or other devices are utilizing the same line.
- Users looking for methods of testing their Internet bandwidth, please see document CH000539.
- See document CH000637 for additional information about limiting their upload bandwidth.

When installing memory on a computer with a 486 computer, because the 486 is a 32-bit processor, when installing 30-pin SIMMs, because a 30-PIN SIMM is 8-bits, you must install 4 SIMMs ( 8x4=32 ) at one time for the memory to properly work.
When installing memory on a Pentium computer, because the processor is a 64-bit processor and 72-Pin SIMMs are 32-bit, you would need to install 2 SIMMs ( 2x32=64 ) at one time for the memory to properly work.
