When an magnified and synthesized image is finally printed on a printing medium based on an original image and a character font data, linear magnifying processing is executed with the aid of a software on the host computer side for the original image optically read by a scanner. In one embodiment, the front cover carries a water pump and internal water distribution passages and covers an overhead camshaft drive mechanism and an oil pump mounted on the engine block. The module further includes an interface circuit configured to control access via the second connector to information stored in the mass storage device based on information in a smart card, e. Switched channels maintain status information about their current status, allowing switched data communication when the channel’s status is active, and permitting the unswitched data path to utilize the channel when the channel’s status is idle. There may also be a storage policy for specifying how to partition a data table for distributing column chunks across multiple servers and for specifying a level of redundancy for recovery from failure of storage servers.
