personal information management (PIM) program

schedule appointments and meetings, store contact information, and manage tasks. Examples of PIM programs are Microsoft Outlook, IBM Lotus Organizer, Sage ACT! and CorelCENTRAL. Android, Apple and BlackBerry smartphones all offer PIM tools by default, and many apps can be purchased to expand their functionality.

e-mail client

send messages over the Internet if you have an account with an ISP. Mozilla Thunderbird is a popular e-mail program on the Internet because it can run on multiple platforms, such as Apple OS X, Linux and Windows. E-mail clients are for e-mail purposes only; however, they are sometimes integrated within a Web browser (Opera Mail is an example of this configuration).

Mail User Agent (MUA).

An e-mail client is also referred to as

Message Transfer Agent (MTA),

An outgoing mail server runs a Message Transfer Agent (MTA), also called a mail transport agent, which routes, delivers and receives messages, usually via SMTP.

browser e-mail programs

E-mail applications such as Mozilla Thunderbird, Windows Live Mail and Opera Mail have been available for years. These applications lack sophisticated features found in applications such as Microsoft Outlook, but are appropriate for many individuals and small businesses.

IP address

Every device on the Internet has a unique IP address, just as every house and business has a street address. An IP address is a series of numbers divided into four sections, each separated by a period, or dot. IP addresses are also called "dotted quads."

Web-based e-mail

Several such services are available, including Google Gmail, Yahoo! Mail and Outlook.com (formerly Hotmail). Web-based e-mail is free, offers e-mail accounts that are accessible from any computer with Internet access, and permits family members who share a single Internet account to have separate e-mail addresses. However, you must have Internet access through a service provider before you can use Web-based e-mail, or you can use a public computer that offers Internet access, such as a computer at a public library.
