A computer so organized can offer significant advantages over the more conventionally organized machine, the foremost advantage being that such an organization facilitates running a job with only a portion of that job in executable memory. This can be done in other computers but the determination of what portions of the program must be in executable memory at any given point in the process is then the responsibility of the person writing the program, i.e., the programmer must schedule the overlaying himself and reflect this schedule in the program.","PeriodicalId":158225,"journal":{"name":"AFIPS '71 (Spring)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1971-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128611165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can neither obtain data for processing nor make its results available. Thus every programming language has contained communication mechanisms. These mechanisms have traditionally been separated into five categories based on the entity with which communication is established. The five entities with which programs can communicate are physical devices (such as printers, card readers, etc.), terminals (although a physical device, they have usually been treated separately), files, other programs, and the monitor. Corresponding to each of these categories are one or more communication mechanisms, some of which may be shared with other categories.","PeriodicalId":158225,"journal":{"name":"AFIPS '71 (Spring)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1971-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130628841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An indicative analogy can be drawn from a look at similar project schedules (Figure 1), for systems of equal magnitude when one system is a conventional development and the other is on-line, real-time system (OLRT), our analysis will reveal the following:\u0000 1. Both systems require essentially the same amount of time and effort in the first three (3) phases.\u0000 2. During unit testing they are also quite similar with OLRT leading slightly.\u0000 3.

One of these, the use of Computer Generated Repeatable Tests (CGRT), is the topic of this paper. The concept of repeatable testing has intrigued teachers for years. The idea is to have the flexibility in class examination procedures to test a student repeatedly over a section of material, and at the student's own pace. The implementation of such a plan involves producing, administering, and grading large numbers of different tests over the same material. In classes of moderate or large size, the mechanics of such procedures has defeated even the most dedicated instructors. The present computer augmented procedure---a result of collaboration between a psychology professor (DDJ) and a computer professional---overcomes the difficulties by fully automating the preparation and grading of individualized tests. Before discussing the technical details of the CGRT process, we will briefly give the rationale behind repeatable testing.","PeriodicalId":158225,"journal":{"name":"AFIPS '71 (Spring)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1971-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125522683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
