ICP meaning in Computing ?

Celeron is Intel's brand name for low-end IA-32 and x86-64 computer microprocessor models targeted at low-cost personal computers.

Celeron processors are compatible with IA-32 software. They typically offer less performance per clock speed compared to flagship Intel CPU lines, such as the Pentium or Core brands. Celeron branded processors often have less cache or intentionally disabled advanced features, with variable impact on performance. While some Celeron designs have achieved strong performance for their segment, most of the Celeron line has exhibited noticeably degraded performance. This has been the primary justification for the higher cost of other Intel CPU brands versus the Celeron range.

Introduced in April 1998, the first Celeron-branded CPU was based on the Pentium II. Subsequent Celeron-branded CPUs were based on the Pentium III, Pentium 4, Pentium M, and Intel Core.
