The new IBM Thinkpad T21 notebook supports features and options that are common with the Thinkpad A21p and A21m. Options such as memory, port replication, and docking are available. All IBM Thinkpad T21 models come with an UltraPort connector on the edge of the top panel. The location of the port allows optimal performance for both applications. Notes MHz only measures microprocessor internal clock speed, not application performance.
Many factors affect application performance.
GB equals one billion bytes when referring to hard disk. Accessible capacity may vary. The V.90 modem can receive data at up to 56 Kbps from a compatible service provider and transmit data at up to 31.2 Kbps. Public networks currently limit maximum download speeds to about 53 Kbps. Actual speeds depend on many factors and are often less than the maximum possible.
