ClientSM: It is the name of the
executable program and file-transmission server (transmitter) program.
With them you can embed macros in charts so that clicking on a symbol will evoke an
executable program or dialog boxes that can be programmed to perform tasks, including instructions to users and displays of useful feedback.
After it is available, an
executable program can be made from any collection of source code by simply running the compiler program so that it does the job of translating it.
With DOS 5.0 alone, the best configuration showed 624.9k free with 612.8k available for the largest
executable program. It was unable to handle all the TSRs and if the others or some network drivers were loaded into low RAM, there would not be enough room to load a big program such as WordPerfect 6.0.
During the first activity (propagation), the virus spreads to other boot sector
executable programs (for an explanation of technical terms used in this article, see the sidebar "Defining the jargon of Viruses" on page 41).
The spread of file viruses was initially slow because most people rarely traded
executable program files.
The result of this improvement was antivirus programs that could detect the vast majority of file viruses by scanning less than 8KB of each
executable program. This technique dramatically increased the speed and efficiency of antivirus products and is still being used today in some products.
* Don't permit computer users to download an
executable program from a public bulletin board and run it on the firm's computers without first performing some software acceptance procedure to ensure it is virus-free.
