Voice input

Today you can also interact with your computer by voice with a voice-recognition system that converts voice into text, so you can dictate text directly onto your word processor or email program. You can also control your PC with voice commands; this means you can launch programs, open, save or print files. Some systems let you search the Web or chat using your voice instead of the keyboard.

COMPOUND NOUNS

Compound nouns consist of two or more words used together as a single word, e.g. hard drive. In a compound there is a headword and one or more modifiers: ink – jet (modifier) printer (head). Modifiers can refer to different things:

- material, e.g. silicon chip = a chip made of silicon;

- use or function, e.g. search engine = a program used to find information on the Web;

- activity or profession, e.g. software engineer = a person who designs software;

- place, e.g. web portal = a site on the Web that acts as a gateway to other sites;

Compound nouns are written in different ways:

- as two separate words, e.g. control panel = a utility that lets you configure and adjust a system;

- as two words joined with a hyphen, e.g. self-test = an automatic examination of a device;

- as one word, e.g. clipboard = a holding place for text or graphics you've just cut or copied;

Unfortunately there are no rules. For example, you may see clip art, clip-art and clipart. Some compounds change over time, for example two words - web site - become hyphenated after a time, and then eventually end up as one word - website.

The two parts of compound nouns may be:

- noun + noun: address bus = a set of wires that identifies locations, addresses, in the main memory; bandwidth = the rate at which data flows through a cable or network; mail merge = a tool that combines a standard letter with a mailing list to create personalized letters;

- adjective + noun: broadband = high-speed connection, e.g. cable or ADSL Internet access; shortcut = a small file, 1KB in size, that links to a real file stored elsewhere; smart card = a plastic card that contains a small chip;

- verb or verbal noun + noun: scrollbar = part of a window that lets you move through a document; recording head = a mechanism that transfers data to a disk;

- verb + particle: add-on = a hardware or software module that can be added to a computer; set-up / setup = the way in which a program or device is configured;
