Condition and Development Characteristics of The Russian Market of Information Technilogies
Introduction of modern information technologies into all spheres of life brought to formation of the new market segment – market of information technologies. The article considers the role of market of information technologies in development of world economy, analyses the main tendencies of development of market of information technologies and presents conservative, innovative forecasts and target prediction of development of this market segment in the Russian economy, considers necessity of state control of market of information technologies using methods of budget-financial, money-and-credit and administrative-legal instruments.

Toward a cooperative network of time-shared computers
Incompatible machines represent an old problem in the computer field. Very often, because of computer incompatibility, programs developed at one installation are not available to users of other installations. The same program may therefore have to be rewritten dozens of times.
A time- and memory-sharing executive program for quick-response on-line applications
APEX is an experimental operation-oriented on-line data analysis system being developed for the TX-2 Computer at MIT Lincoln Laboratory. This paper describes the executive program which has been designed to satisfy the needs of that system as well as the other activities currently soaking up the computational energies of TX-2. These needs are developed into a set of requirements for a fast-response time-sharing system. The requirements, in turn, lead to a series of design decisions which involve both the hardware and software parts of the system. A memory and program-sharing system, with the hardware to make such a system efficient, takes the form of a complex of apparent computers, one for each console, which share some common hardware (TX-2). The salient characteristics of these computers are described as well as the executive program structure which gives them apparent reality.
