Commercial computer system development has followed development of hardware technology and is usually divided into four generations:
1. First generation (1945–1955)—vacuum tube technology.
2. Second generation (1955–1965)—transistor technology.
3. Third generation (1965–1980)—integrated circuit (IC) technology.
4. Fourth generation (1980–??)—Very Large Scale Integrated (VLSI) circuit technology.
We will not elaborate on the architectural details of the various machines developed during the [...]

If spending a bit more noticeably improves performance, reliability, or cooling, we won’t begrudge the extra few dollars.
Reliability
Reliability ties for top importance with size. We’ll [...]

Today’s modern BIOSes are incredibly automated for most of the work we do on today’s systems. The vast majority of jobs that used to require going into CMOS setup—installing hard drives, adding RAM, etc.—now work automatically. Even though many functions are now automated, the need for understanding how to confi gure and maintain your CMOS [...]
