Internet Controlled Thermostats
An Internet thermostat is a programmable building thermostat capable of connecting to an Internet protocol (IP) network. Through the IP connection, you can remotely send instructions to an Internet thermostat to turn it on or off or change its programming.
Introduction to Computer Network Speed
Two key elements that contribute to network speed are bandwidth and latency. Learn more about these two important networking concepts that help determine computer network performance.
Network Topologies
Common network topologies include the bus topology, star, and ring. Learn more about these and other topologies in computer network design.
Introduction to Peer to Peer Networks
Peer to peer networks share responsibility for processing data among all of the connected devices. Peer-to-peer networking (also known simply as peer networking) differs from client-server networking in several respects.
Introduction to Client Server Networks
The term client server refers to any network design utilizing networked client and server computers and application software. Web, FTP, email, DNS and many other database applications are client-server designs. Client-server networks offer efficient shared access to network resources. Learn more about the client-server model in this introductory tutorial.
Connect a Computer to a TV
Sometimes you may want to connect a computer to TV monitors for displaying digital pictures and video on the television. Several different methods exist to connect a computer to a TV as described here.
Connect Two Home Computers for File Sharing
The simplest kind of home network contains exactly two computers. You can use this kind of network to share files, a printer or another peripheral device, and even an Internet connection. Two computers can be networked together for file sharing in several different ways.
Introduction to the Network Adapter
The network adapter is an essential component of any computer network. Learn about the different types of network adapter hardware and software and the considerations involved in obtaining and installing one.
Wi-Fi Hotspots
Wi-Fi hotspots provide Internet access to wireless network devices in public locations such as downtown centers, cafes, airports and hotels. Businesses are incresaingly using Wi-Fi hotspots for their internal (intranet) networks. Follow these guidelines to use WiFi hotspots most effectively.
Internet Protocol Tutorial
IP addressing has been in use for decades. It is an essential technology of the Internet and home and business networking. Learn about the basics of IP addressing in this tutorial, including addressing, subnets and CIDR.
Wireless Standards - 802.11b 802.11a 802.11g and 802.11n
Which of the popular wireless home networking standards - 802.11b, 802.11a, 802.11g or 802.11n - is right for you? This article explains the pros and cons of each of these wireless standards.
DSL and Cable Broadband Speed Tweaks
So-called DSL tweaks are optimizations you can make to your computer and local network to increase the speed of your broadband Internet connection. While many tweaks exist for low-speed (dialup) Internet, the same methods often do not apply to DSL tweaks.
Internet Domain Extensions
Domain extensions on the Internet are often called top level domains (TLDs). Dot-com (.com) is the most commonly used top-level domain extension on the Internet. Many others exist, however.
P2P Networking and P2P Software
P2P is peer-to-peer computer networking. P2P networking and P2P software applications have evolved in recent years to include may new peer-to-peer software systems.
Information Technology Outsourcing
Many corporations are outsourcing Information Technology (IT) jobs in the United States to consulting firms or offshore organizations. Here's what outsourcing means to your career in Information Technology.
Network Bandwidth and Latency
Two key elements that determine computer network performance are bandwidth and latency. Learn more about network latency and the impact of high latency in this introductory article.
OSI Model Reference Guide
The OSI model provides a conceptual framework for understanding the architecture of network protocols and services. This article is a reference guide to the OSI model.
VPN Tutorial
This tutorial explains VPN concepts. A VPN - Virtual Private Network - implements private network communications over public infrastructure using a combination of hardware, software, and protocol solutions.
What Is a VPN?
A Virtual Private Network (VPN) implements private networks over public infrastructure
Acceptable Use Policy - AUP
An Acceptable Use Policy is a written agreement all parties on a community computer network promise to adhere to for the common good. An AUP defines the intended uses of the network including unacceptable uses and the consequences for non-compliance.
DSL Availability
DSL (Digital Subscriber Line) service remains unavailable in many areas. Use these resources to check DSL availability for a particular home or office location.
CIDR - Classless Inter-Domain Routing
CIDR - also called supernetting - is one system used by Internet routers to manage IP subnetworks. CIDR was developed in response to a shortage of IPv4 addresses and is described by a special CIDR notation.
File Sharing 101
Computer networks allow you to share files with friends, family, coworkers and customers. Learn about the different methods for file sharing including Windows, FTP, P2P and Web based.
Both DSL and cable modem service bring broadband networking to the home and small business at an affordable price. But what are the differences between the two?
