The objective is to investigate significant developments in advanced computers and to explore the relationship between programming and new concepts of computer organization. Two specific studies are in progress: Data Sequencing and Vertical Data Processing.
The health care industry represents a major part of the U.S. economy. In 2007 total U.S. health care spending comprised 16% of the country’s GDP, amounting to $2.3 trillion.7 According to the National Institute of Standards and Technology, approximately 20% of health care expenditure, some $460 billion in 2007, was dedicated to the tasks of […]
Cryptographic techniques which can be used to maintain the confidentiality of information processed by computers are dealt with. Special emphasis is paid to the unique characteristics of computer files that make many cryptographic methods of little use. Relative security, costs, and preferred methods are included in this paper.
Some of the most advanced programming techniques have emerged either because of the complete lack of coordinated standards, or because there was too rigid standardization and too soon, whether it was planned that way or not. The standardization that was lacking, or too rigid, was in programming techniques, programming languages, programming terminology, equipment techniques, available equipment, and specification and documentation methods for equipment, programs, languages, and problems to be solved. For example, common programming languages developed because of the lack of standardized equipment or languages for their use.
Communications of the ACM (CACM) is now a fully Open Access publication.
By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
