A cordless phone also has no wires. It can be useful in the office or the factory. Imagine that you are working in an office and a suctomer calls you asking for some information. If you have a cordless phone, you can carry it with you and look up the information that your caller wants. In other words, you can walk to a distant part of the office or factory to check the information without putting the phone down.
One new model has lately been developed for business people. With this phone, you do not have to look up the number of the percon you want to ring. The phone has a small computer in it. You say the name of the person you want to ring. The phone recognizes the name and then dials the corret number. You can record up to 20 different names on this kind of phone. If you are a person who offen forgets people＇s telephone numbers this could be the phone for you. However you have to remember their names.
