With the widespread use of the personal computer, many authorities in the field of(56)have pointed out the need for computer literacy.Unfortunately, there is no(57)agreement as to what the term "computer literacy" means. Some feel that computer literacy means knowing how to make the computer "compute"; that is knowing how to program computers in one or more programming languages.Others feel that knowing how to program is merely a small segment of computer literacy. These people(58)the major emphasis in schools should be on teaching how to effectively use the many software packages that are available.Still others suggest that computer literacy education is not required. They suggest that computers are being so rapidly integrated into our society that using a computer will be as(59)as using a telephone or a video tape recorder, and that special education will not be necessary. (60)of one's definition of computer literacy, it is recognized by most that learning to use a computer is indeed an important skill in modern society.

An architectural Style. defines as a family of such systems in terms of a (1) of structural organization.More specifically an architectural style. defines a vocabulary of (2) and connector types, and a set of (3) on how they can be combined. For many styles there may also exist one or more (4) that specify how to determine a system's overall properties from the properties of its parts. Many of architectural styles have been developed over the years.The best-known examples of (5) architectures are programs written in the Unix shell.

Typically, these are concern with the establishment of(66)the network and with the control of the flow of messages across this channel. The provision of such facilities is only part of the network requirements, however, since in many applications the communicating computers may be of different types. This means that they may use different programming languages and, more importantly, different forms of(67)interface between user(application)program, normally referred to, as application processes or APs, and the underlying communication services may be(68)For example, one computer may be a small single -user computer, while another may be a large(69)system. In the earlier days of computer communication, these issues meantthat only closed communities of computers(that is, from the same manufacturer)could communicate with each other in a meaningful way. IBM’s Systems Network.
Architecture (SNA) and DEC's Digital Network Architecture (DNA) are just two examples of Communication software packages produced by manufacturers to allow their systems to be int erconnected together. These proprietary packages, however, of which there am still many inexistence, do not address the problem of universal interconnect ability, or open systems interconnection. In an attempt to alleviate this problem,(70), in the late 1970s, formulated a reference model to provide a common basis (or the coordination of standards developments and to allow existing and evolving standards activities to beplaced into perspective with one another.
