Personal Computer System

Personal firewalls explained--for remote corporate and home users. In today's work environment, increasing numbers of mobile employees are using PCs, laptops, and handheld devices to connect to corporate servers. That's great for productivity, but it can also pose a security nightmare. Many of these remote systems are at best minimally protected against hackers and other intruders, which means they can provide an easy avenue into the network. An effective--and cost effective--way to address this liability is through the use of personal firewalls. In "Personal Firewalls for Administrators and Remote Users," security professional Lisa Yeo presents this vital security technology in a format that system administrators and home users alike can use to zero in on exactly what they need to know to secure their computers against outside intruders. In her clear and engaging style, Yeo explains everything from the basics of home computer security and networking to advanced topics such as interpreting log files and troubleshooting, configuring, and maintaining personal firewalls. Along the way, you'll learn how to choose a personal firewall from the products available today, how to deploy personal firewalls in home and corporate environments, and more. This book describesPersonal firewalls completely--from the basics to advanced topics, for users and administratorsComparisons of firewalls--select the one that works best for your network situation and operating systemConfiguration, maintenance, and troubleshooting--all you need to set up and run personal firewalls for remote and home users This book is appropriate for system administrators; mobile corporate employees using PCs, laptops,and handhelds; as well as savvy home computer users. Coverage includes widely available software packages running on systems including Linux, Windows, and Mac OS.

Cluster computers provide a low-cost alternative to multiprocessor systems for many applications. Building a cluster computer is within the reach of any computer user with solid C programming skills and a knowledge of operating systems, hardware, and networking. This book leads you through the design and assembly of such a system, and shows you how to mearsure and tune its overall performance. A cluster computer is a multicomputer, a network of node computers running distributed software that makes them work together as a team. Distributed software turns a collection of networked computers into a distributed system. It presents the user with a single-system image and gives the system its personality. Software can turn a network of computers into a transaction processor, a supercomputer, or even a novel design of your own. Some of the techniques used in this book's distributed algorithms might be new to many readers, so several of the chapters are dedicated to such topics. You will learn about the hardware needed to network several PCs, the operating system files that need to be changed to support that network, and the multitasking and the interprocess communications skills needed to put the network to good use. Finally, there is a simple distributed transaction processing application in the book. Readers can experiment with it, customize it, or use it as a basis for something completely different.

Computer system - A computer system consists of a set of hardware and software which processes data in a meaningful way. The personal computer or PC exemplifies a relatively simple computer system.

System Builder - In the computer industry, a System Builder is a person or company who is in the practice of creating (generally from scratch) a personal computer system from individual components. That is, a person who takes such components as a case, a motherboard, processer, soundcard, and the like and combine them into a working machine together, often for retail sale.

Network computing system - Network computing system. Computer systems that allow personal computers (clients) to obtain needed information from databases in a central computer (server).

Amiga Fast File System - The Amiga Fast File System (FFS) is a file system used on the Amiga personal computer. The Amiga Old File System (OFS) was too slow to keep up with hard drives.

Computer System Design - Computer System Design Vulnerability (computer science) - In computer security, the word vulnerability refers to a weakness in a system allowing an attacker to violate the integrity, confidentiality, access control, availability, consistency or audit mechanism of the system or the data and applications it hosts. Vulnerabilities may result from bugs or design flaws in the system. Mensch Computer - The Mensch Computer is a computer system based on the W65C265 microcontroller (which implements both the 16-bit instruction set of the W65C816/65816 ...
