Communications Software

Using telephone lines and working through the computer's modem, communications software makes it possible to communicate to any location in the world using either fax or electronic mail. A fax transmits whatever copy is on an original sheet of paper (text, graphics, or handwriting) to another computer or fax machine. Electronic mail (e-mail) is a text message. It remains in the receiver's computer until retrieved. The message can be stored in either the sender's or the receiver's computer for later processing. Attachments or files can also be sent via e-mail.

Utility Software

Utility software is used to diagnose computer problems and repair them. A major type is a virus (or "illness") checker. It checks for viruses the computer may have received from downloading information received from the Internet, e-mail, or another disk. Although some viruses may do little damage, others can cause serious damage to files and/or the computer operating system. It is important for a computer owner to find a virus-check program, install it, use it, and keep it continually updated. New viruses are found continually, and the only way to be safe is to update. Some antivirus software allows easy updating by downloading new files from the Internet.

Educational Software

By teaching by means of games, educational soft ware is designed to make learning fun. The approach used in educational software is that of a tutorial in which the learner competes with him or herself. Such software appeals to persons of all ages but particularly to young children, who can learn skills related to reading and arithmetic. Older children and adults can learn or improve on a wide variety of more mature skills.

Special Software Acquisition Arrangements

Some kinds of software are given away. Another kind permits the potential user to try the software before purchasing it. Freeware software is free for those who ask, but the rights remain with the developer. Public domain software is free to the user without any copyright or other restrictions. Shareware software permits potential buyers to try out the software. A user who likes it may purchase it by sending payment to the developer. The developer in turn may send the buyer sup porting materials and information.
