Nor were there animated arrows or zoom-ins. Not here though. The paper simply lay there, inert and uncooperative. Or the programs can be set to randomly let through bits of mail unscreened, for those who are nostalgic for miscellaneous paper mail. Ordinarily, each computer network has its own commands and ways of doing things.
Human beings understand the concept of synonyms easily, but computers are more limited.
Rather than try to program in Roget's, computer programs and computer networks have been set up to respond in predictable ways to specified commands. In the past, the problem has been that the commands were different for each piece of software. They are analogous to a small post office where the patrons must bring letters the office and the postal employees place them in a pigeon-hole for another patron to pick up. As long as the employees understand the filing system, it doesn't fundamentally matter whether the pigeon- holes are arranged alphabetically, by street address, or by Social Security Number. To extend the analogy, when the postal patrons start wanting to communicate with people who use other post offices, both a system of distribution for the mail to get from one office to another, and a uniform system of addressing are needed.
