One of the functions of the(71)is to store the applications programs { or the various secondaries. The(72)may have similar or dissimilar functions. The same control code received from two different, secondaries may warrant two different actions on the part of the host computer. If the system so requires, the host computer must also provide(73)for the centralized data and the software for database management. Data information is normally stored in auxiliary memories to which the computer has ready access. The(74)peripherals connected to the host computer allow for human entry and intervention. As needs change, application programs may require additions, deletions, or changes. Data link problems also arise which are(75)the range of the computer's programmed capabilities. In such cases, human entry is required to make the necessary changes to resolve the existing problems.

In data communication, data link is those parts of two data terminal equipments that are c
ontrolled by a protocol along with the(71) data circuit, which together enable data(72). So-called protocol means, in short, a set of rules that determines the behavior. of functional units in achieving communication.Data circuit, however, consists of a pair of(73) transmission channels that provides a means of two-way data transmission. Between data switching exchanges, the data circuit may or may not include data circuit-terminating equipment (DCE), depending on the type of(74) used at the data switching exchange. Between a data station and a data switching exchange or data concentrator, the data circuit includes the DCE at the data station end, and may include equipment(75) to a DCE at the data switching exchange or dam concentrator location.

Networks can be interconnected by different devices. In the physical layer, networks can b
e connected by(66)or hubs, which just move the bits from one network to an identical network. One layer up we find bridges and switches, which operate at data link layer. They can accept(67), examine the MAC address, and forward the frames to a different network while doing minor protocol translation in the process. In the network layer, we have routers that can connect two networks. If two networks have(68)network layer, the router may be able to translate between the packet formats. In the transport layer we fmd transport gateway, which can interface between two transport connections. Finally, in the application layer, application gateways translate message(69). As an example, gateways between Internet e-mail and X.400 e-mail must(70)the e-mail message and change various header fields.
