The education sector remains abuzz with cost-cutting expectations despite pressures to increase services. Automation of costly manual tasks could save funds for many of these institutions, specifically in data protection. The IT departments of schools and universities can take advantage of a proven cost-savings opportunity in data protection that…

Mobile use of the Internet is on target to surpass fixed use by 2014. Three-fourths of all college/university students have purchased or intend to purchase an Internet-enabled handheld device within the next year. The smartphone market is changing almost monthly. Attempting to manage even just one or a few "devices" is becoming a lost…

So many communications channels, so little time and, usually, so few resources is the situation today's communicators face. Educational institutions, places steeped in history and tradition, "have been slow to react." But while the communications channels have changed, the fundamentals of communication haven't. Maintaining perspective about…

Reviews the characteristics of electronic communications technologies and their role in knowledge utilization. The uses of various technologies, relationships among technologies, and success in the marketplace are addressed; and issues for knowledge utilization research are discussed. (17 references) (EA)

Addresses the growth of signatures in document management. Describes the three basic types of electronic signature technology: image signatures, digital signatures, and digitized biometric signatures. Discusses legal and regulatory acceptability and bringing signatures into document management. (AEF)

Persistent myths have lessened the impact of ICTs on education. Happily they are balanced by miracles of theory and practice that are gradually gaining the upper hand. We counter the myth that innovation in the application of ICTs is the preserve of industrialised countries by listing examples of innovations from southern Africa that have set…

Presents an enriched video metadata framework including video authorization using the Video Annotation and Summarization Tool (VAST)-a video metadata authorization system that integrates both semantic and visual metadata-- metadata integration, and user level applications. Results demonstrated that the enriched metadata were seamlessly…

The current version of the IP protocol, IPv4, is the most widely used protocol in computer networks. This article describes mechanisms that can be used to facilitate the transition to the new version of the IP protocol, IPv6, and examines usability, usefulness and manageability. Describes how some of these mechanisms were applied to the Greek…

Describes the layered model of Open Systems Interconnection (OSI); summarizes the three upper and lower layers; and discusses data communications standards associated with specific layers. Architectural concepts are explored, including hierarchy and abstraction, levels of dialogue, internetworking, and end-to-end communication. OSI is compared…

Examines potential solutions to the problem of personal computer cabling and configuration and serial port performance, namely "FireWire" (P1394) and "Universal Serial Bus" (USB). Discusses interface design, technical capabilities, user friendliness, compatibility, costs, and future perspectives. (AEF)

Explains how the Directory Service (CCITT X.500/ISO 9594) became an international standard in response to the difficulties of keeping data on information network users current and accessible. Uses of X.500 are described, a technical overview is provided, its functions and protocols are assessed, and directory projects and products are discussed.…

Management of heterogeneous networks is complicated by the persistence of proprietary management schemes. The need for integration of network management capabilities is pressing. The International Organization for Standardization is developing standards for managing networks as part of the Open Systems Interconnection (OSI) effort. OSI management…

Reviews some of the projects and organizations concerned with promoting conformance and interoperability testing of Open Systems Interconnection (OSI) products and describes OSI products available from computer manufacturers and vendors. A list of references includes 57 articles that mention specific vendors and 11 general articles about OSI…

Discusses how various Open Systems Interconnection (OSI) application layer protocols can be used together, along with the Presentation and Session protocols, to support the interconnection requirements of applications. Application layer protocol standards that are currently available or under development are reviewed, and the File, Transfer,…

The edi conceptual model is being developed to define common structures, services, and processes that syntax-specific standards like X12 and EDIFACT could adopt. Open Systems Interconnection (OSI) is of interest to edi because of its potential to help enable global interoperability across Electronic Data Interchange (EDI) functional groups. A…
