| RAM |
| Random Access Memory. The computer’s primary working memory in |
|
|
| which program instructions and data are stored and are accessible to the |
|
|
| CPU. Information can be written to and read from RAM. The contents of |
|
|
| RAM are lost when the computer is turned off. |
|
| RISC Core |
| LSI Logic SCSI chips contain a RISC (Reduced Instruction Set |
|
|
| Computer) processor, programmed through microcode SCRIPTS. |
|
| ROM |
| Read Only Memory. Memory from which information can be read but not |
|
|
| changed. The contents of ROM are not erased when the computer is |
|
|
| turned off. |
|
| SCAM |
| SCSI Configured AutoMatically. A method to automatically allocate SCSI |
|
|
| IDs using software when SCAM compliant SCSI devices are attached. |
|
SCSI |
| Small Computer System Interface. A specification for a |
|
|
| peripheral bus and command set. The original standard is referred to as |
|
|
|
| |
| The SCSI specification which adds features to the original SCSI |
| |
|
| standard. |
|
| pc |
| The current SCSI specification which adds features to the |
|
|
| standard. |
|
| SCSI Bus |
| A host adapter and one or more SCSI peripherals connected by cables |
|
|
| in a linear chain configuration. The host adapter may exist anywhere on |
|
|
| the chain, allowing connection of both internal and external SCSI |
|
|
| devices. A system may have more than one SCSI bus by using multiple |
|
|
| host adapters. |
|
| SCSI Device | Any device that conforms to the SCSI standard and is attached to the |
| |
|
| SCSI bus by a SCSI cable. This includes SCSI host adapters and SCSI |
|
|
| peripherals. |
|
| SCSI ID |
| A way to uniquely identify each SCSI device on the SCSI bus. Each SCSI |
|
|
| bus has eight available SCSI IDs numbered 0 through 7 (or 0 through 15 |
|
|
| for Wide SCSI). The host adapter usually gets the highest ID, (7 or 15) |
|
|
| giving it priority to control the bus. |
|
| SCSI SCRIPTS | A SCSI programming language that works with the SCRIPTS processor |
| |
|
| that is embedded on the LSI53C8XX or LSI53C10XX device. These |
|
|
| SCRIPTS reside in host computer system memory. |
