The DEVICE File (#3.5) is stored in the global root of ^%ZIS(1, and each entry corresponds to a name for I/O (Input and Output) in the VistA system. Generally speaking characters are sent to and received from an I/O device in most computer systems as a normal part of interaction with a user.
The devices in VistA are segmented by the TYPE Field which has the following values:
| *INTERNAL ABBREVIATION* | *EXTERNAL VALUE* | *Intended use* |
| TRM | : TERMINAL; | hard connected terminals such as consoles |
| OTH | :OTHER; | |
| MT | :MAGTAPE; | sequential magnetic tape |
| SDP | :SDP; | unused- was Sequential Disk Processing - MUMPS-as-OS disk storage |
| SPL | :SPOOL; | unused - was in-MUMPS disk/printer spooling |
| BAR | :BARCODE READER; | |
| HFS | :HOST FILE SERVER; | commonly used - Filesystem storage, print spooling, etc. |
| VTRM | :VIRTUAL TERMINAL; | soft connect terminals over the network |
| HG | :HUNT GROUP; | providing for banks of "alike" devices |
| RES | :RESOURCES; | synchronization and limiting background processes |
| CHAN | :NETWORK CHANNEL; | devices attached with TCP/IP addresses and ports |
| IMPC | :IMAGING WORK STATION |
