Toner Cartridges

Toner cartridges allow you to use your printer effectively. A toner cartridge contains toner, and needs to be replaced when the toner runs out.

Toner is a powder used in laser printers and photocopiers which forms the text and images on the printed paper. In its early form it was simply carbon powder.

Toner cartridges are very expensive, as they are specifically made for your brand of printer. Some toner cartridges are even made for a specific printer model. However it is now possible to reduce the cost of printing by purchasing your toner cartridge online, or by recycling your toner cartridge.

Laptop Batteries

A laptop computer (also known as notebook computer) is a small mobile personal computer, usually weighing from 1 to 3 kilograms (2 to 7 pounds).

Laptops usually run on batteries, but also from adapters which also charge the battery using mains electricity.

Current models use lithium ion batteries, which have largely replaced the older nickel metal-hydride technology. Typical battery life for most laptops is two to five hours with light-duty use, but may drop to as little as one hour with intensive use. Batteries gradually degrade over time and eventually need to be replaced, depending on the charging and discharging pattern, from one to five years

Spam Software

Spam Software

Spamming is the use of any electronic communications medium to send unsolicited messages in bulk. The most common form of spam is that delivered in e-mail as a form of commercial advertising.

Spammers obtain e-mail addresses by a number of means: harvesting addresses from Usenet postings, DNS listings, or Web pages; guessing common names at known domains. Many spammers utilize programs called web spiders to find email addresses on web pages, although it is possible to fool the web spider by substituting the “@” symbol with another symbol, for example “#”, while posting an email address.

Computer users can avoid e-mail spam in several ways:

* End-users should take precautions to avoid publicising their e-mail addresses
* End-users can use automated e-mail filtering on their own computers
* System administrators can use appropriate tools to trap e-mail spam at the mail server level

Anti-spam programmers have released several tools—intended for both end users and for systems administrators—which automate the highlighting, removal or filtering of e-mail spam by scanning through incoming and outgoing e-mails in search of traits typical of spam. A popular commercial solution in this area is a spam firewall appliance from Barracuda Networks.

Broadband Phone

Broadband Phone

Broadband Telephony is the utilisation of broadband connections to deliver voice calls. Typically, services are hosted, meaning customers enjoy traditional phone functionality without the need to purchase a phone system at all. Calls are transmitted as IP Packets to the host company, where they either ‘break out’ to the public networks, or continue as IP calls across the Internet.

Due to the utilisation of Voice over IP, calls can be delivered across the internet for free in some circumstances.

VoIP

VOIP

VoIP (also called Voice over IP, IP Telephony, Internet telephony, and has also been branded Digital Phone) is the routing of voice conversations over the Internet or any other IP network. The voice data flows over a general-purpose packet-switched network, instead of traditional dedicated, circuit-switched voice transmission lines.

Voice over IP traffic may be deployed on any IP network, including ones lacking a connection to the rest of the Internet, for instance on a private building-wide LAN.

You can make calls for free using this service, and many providers allow free or low cost set up of VoIP.

Broadband

Broadband Internet access, often shortened to is a high data-transmission rate internet connection. DSL and cable modem, both popular consumer broadband technologies, are typically capable of transmitting 512 kilobits per second (kbit/s) or more, approximately nine times the speed of a modem using a standard digital telephone line.

You can often get better deals on broadband connection by selecting your broadband provider online. This is because Internet Service Providers can pass on the savings of doing business online to the customer.
