It was annoying, just right when we want to use computer, the performance became slow. And usually it took times to figure it out, whats happening. The first suspicious came to virus attack and its variant, after checking for a long time virus not found. Ordinary user will confuse about what had to be done next, until the realize they forget to clean registry.

The registry of a computer is a system of hidden files which is the backbone of all information. It records every action, process and program used on a computer. Unfortunately, it becomes cluttered and disorganized, over time, because the registry does not delete expired data. Read rest of review…

You’ve might heard news lately, more people are helping catch burglars, thief, etc by setting up some surveillance tools. Some tools are very simple to install, and off course more cheaper the prices, more peoples wants to get it. And the most important is could operated in a few seconds.

The tools itself are not just a CCTV, or webcam, but also a computer spy. Read rest of review…

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol’s packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user. Much of IP telephony focuses on that challenge. Read rest of review…

About ten years ago, the only way to connect ourselves to internet was using a dial-up connection which had lots of limitations. To begin with, dial-up was not reliable, slow, and often tends to disconnect on the slightest interruption on the line. So, based on today’s standards, the dialup will be disregarded by many users for the above mentioned reasons.
Soon, the invention of splitters and filters paved the way for broadband, the always ‘on’ internet connection. In simple language, broadband refers to a wide range of technologies that offer reliable, high speed internet access. Read rest of review…

Social network analysis [SNA] is the mapping and measuring of relationships and flows between people, groups, organizations, computers, URLs, and other connected information/knowledge entities. The nodes in the network are the people and groups while the links show relationships or flows between the nodes. SNA provides both a visual and a mathematical analysis of human relationships. Management consultants use this methodology with their business clients and call it Organizational Network Analysis [ONA]. Read rest of review…

Dynamic network analysis (DNA) varies from traditional social network analysis in that it can handle large dynamic multi-mode, multi-link networks with varying levels of uncertainty. DNA, like quantum mechanics, is a theory in which relations are probabilistic, acts of measurement change the network, movement in one part of a network propagates throughout the entire system, and so on. However, unlike quantum mechanical atoms, DNA nodes can learn. The Dynamic Network Analysis Section focuses on advancing our understanding of social networks through DNA. The section will organize meetings, newsletters, websites, mailing lists and/or special journal issues to achieve its objectives, including the fostering of rich dialog among DNA researchers.

The world has changed a lot in the last couple of decades. Instead of simply dealing with local or regional concerns, many businesses now have to think about global markets and logistics. Many companies have facilities spread out across the country or around the world, and there is one thing that all of them need: A way to maintain fast, secure and reliable communications wherever their offices are.

Internetworking Protocols
Most of the network protocols currently in use have changed little since the early definitions of the ARPA research and education network when trust was the norm. To have a secure foundation for the critical Internet applications of the future, severe weaknesses must be addressed: lack of encryption to preserve privacy, lack of cryptographic authentication to identify the source of information, and lack of cryptographic checksums to preserve the integrity of data (and the integrity of the packet routing information itself). New internetworking protocols are under development which use cryptography to authenticate the originator of a packet and to protect the integrity and confidentiality of data. Read rest of review…

Security Policy
A policy is a documented high-level plan for organization-wide computer and information security. It provides a framework for making specific decisions, such as which defense mechanisms to use and how to configure services, and is the basis for developing secure programming guidelines and procedures for users and system administrators to follow. Because a security policy is a long-term document, the contents avoid technology-specific issues. Read rest of review…
