PC computing is a novel approach to computing in which there is no operating system, and applications are provided with direct interfaces to the hardware. Bare PC systems are of particular interest for secure, reliable, and efficient peer-to-peer communication between users in view of their inherent simplicity. In this paper, we first provide a brief(More)
We compare VoIP performance on IPv6 and IPv4 LANs in the presence of varying levels of background UDP traffic. A conventional softphone is used to make calls and a bare PC (operating systemless) softphone is used as a control to determine the impact of system overhead. The performance measures are maximum and mean delta (the time between the arrival of(More)

We present a bare PC Web server design that runs on any Intel 386 based PC without any hard disk and other supporting software. This server design is based on simplicity and minimal functionality. We identify design issues related to such server and provide our preliminary performance measurements in comparison with IIS and Apache servers. We have found(More)
We describe the architecture, design, and implementation of a VoIP softphone that runs on a bare Intel-386 (or above) based PC. We compare the performance of bare PC and WinRTP softphones on the Internet by determining call quality and measuring the values of jitter, delay, and packet loss. We also conduct experiments on a LAN to test the limits of the bare(More)
— Working with Web browsing history provided by current browsers is a daunting task for Web users and a major source of user frustration. Users interact with Web browsing history using the Forward and Back navigation buttons and the bookmarks pull-down menus. This research presents an appropriate model for representation of Web browsing history with its(More)
Windows softphones show that the bare PC softphone has packet inter-arrival times (delta) that are closer to the ideal value, and intrinsic jitter values that are smaller and less variable. Moreover, the total time to complete the key exchange, and the time to generate RSA keys of various sizes or a number of RSA keys of a given size are significantly less(More)
