Explain the difference between a fixed program machine and a stored program machine. 7 Summary 11 Summary A computer is a programmable electronic device that can process, store and retrieve data. It processes data according to a set of instructions or program. All computers consist of two basic parts, namely, the hardware and software.

They employed a positional number system8 and used the base 60 system. The symbol representing 1 could also (depending on the context) represent 60, 602, 603, etc. It could also mean 1/60, 1/3600 and so on. There was no zero employed in the system and there was no decimal point (no ‘sexagesimal point’), and therefore the context was essential. The example above illustrates the cuneiform notation and represents the number 60 + 10 + 1 = 71. They used the base 60 system for computation, and one possible explanation for this is the ease of dividing 60 into parts as it is divisible by 2, 3, 4, 5, 6, 10, 12, 15, 20 and 30.

The Celts were skilled in working with iron and bronze, and they gradually expanded into Europe.  The early Celtic period was known as the ‘Hallstatt period’, and the later Celtic period is known as the ‘La Téne’ period. The La Téne period is characterized by the quality of ornamentation produced. The Celtic museum in Hallein in Austria provides valuable information and artefacts on the Celtic period. The Celtic language has similarities to the Irish language. However, the Celts did not employ writing, and the ogham writing developed in Ireland was developed in the early Christian period.
