NASA was still a young agency when Apollo was introduced. The first space program was Mercury, whose mission was to launch astronauts, one at a time, into space and then into orbit.
Following Mercury was the Gemini program. Gemini spacecraft held two astronauts and saw was the first to really start with science and gear experiments. It was during Gemini that Ed White became the first American to perform an EVA (spacewalk).
Apollo directly followed Gemini, and the Space Shuttle program followed Apollo.
Only lunar (moon) mission spacecraft were called Apollos. The first manned space flight program was named Mercury, the second was named Gemini. These were test/learning programs leading to the third named Apollo. These early U.S. programs were named after Greek and Roman Gods. Apollo was a god of light and the sun, truth and prophecy and other talents. The spacecraft that were made as part of the Apollo program are called Apollo spacecraft and the flights called Apollo missions. Apollo 11 was the first Apollo mission to put men on the moon.
It was called the Apollo and Soyuz program, in this program both the spacecrafts docked with each other, and the crew changed over.
The two major successes of the Apollo program were the successful orbit of the Moon by Apollo 8 (Christmas Eve, 1968) and the successful lunar landing by Apollo 11 on July 20, 1969. During the latter, Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon. Ten other astronauts explored the Moon between 1969 and 1972.
The Saturn C-1 (also known as the Saturn 1) was only used for ten flights near the beginning of the Apollo Program, to test various aspects of the Apollo spacecraft and other technology. There were never any manned launches.
First of Apollo 11 was not a Shuttle craft, as it mot at all reusable. It is called the apollo 11 after the other Apollo starting with Apollo 7.

The Apollo space program came to an end in 1975. It was responsible for the manned Moon flights. It was run by NASA, the National Aeronautics and Space Administration. It is a United States Government Agency and is now involved in other space programs,https://www.nasa.gov/

A compiler.
One is a spreadsheet program made by Lotus the other is a spreadsheet program made by Microsoft. The main difference is the way in which formulas are entered - in Excel they are preceded by the = symbol and in 1-2-3 they are preceded by the + symbol.
A program is software. One program can call another program to be run. Computer systems consist of lots of individual programs which work together. Applications consist of lots of individual programs that work together. So programs need to be able to call other programs. A good example is that a menu can sometimes be one separate program and each option it calls could potentially be other individual programs.
virus
A virus is a piece of a program that attaches itself to other programs. In contrast, a worm is a full program that spreads itself, and a trojan is a harmful program that passes itself off as, and in some cases might also be, as useful program.
The operating system.
It closes Windows when your working on other programs.
a program that installes other programs eg. games
