In first generation and second generation computers there was no concept of architecture, the implementation was the architecture and every model of computer was totally different. Software portability did not exist, unless both machines were identical models with no custom features (and custom features and modifications were common). Only in third generation computers starting with the IBM System/360 in 1964 was the concept of computer architecture as something separable from implementation created.
Note: this same problem happened in the 1970s with first generation (4 bit & 8 bit) microprocessors. But at least with microprocessors it was corrected in the second generation (16 bit) processors.

∙ 12y ago- Vacuum tubes
- Large
- Expensive
- Slow (but faster then anything else at that time)
- Needed expensive refrigeration system to remove heat generated by vacuum tubes
- Very high operating voltages (touching circuits could kill you)
- Unreliable
- Came with onsite Customer Engineer to repair machine when it failed
- Usually leased, not sold
- Different architectures for business (e.g. decimal/character oriented) and scientific (e.g. binary/word oriented) machines
- Concept of computer architecture did not exist
- etc.

What meaning of Univac in first generation?
This is the term used for big vacuume tubes which were used in the construction of first generaiton of computers.
What does a semiconductor have to do with a computer?
some first generation computers used germanium point contact diodes in their logic gates to reduce their vacuum tube parts count.second generation computers used discrete germanium or silicon transistors.third generation and later computers use silicon integrated circuits.

Are Computers that used transistors are referred to as third-generation computers?
no, second generation. third generation computers used ICs.
What is a first generation computer?
History of computer is divided into 5 generation. The first generation of computer started form 1941 till 1956. In this generation vacuum tubes are used in computers and computers are big enough that one computer could be such big as a whole room.
