Explain the handheld systems. List the issues related to the handheld system.

- Handheld devices are palm tops and cellular telephones with connectivity to a network.

- These devices are of limited size which leads to limited applications.

- They use a memory 512KB to 16MB as a result the operating system and applications must use the memory efficiently.

- The speed of the processors is only a fraction of speed of the PC processors and for faster processors larger battery is required.

- These devices use very small display screens so reading mails and browsing must be condensed to smaller displays.
