Abstract
Data centers, facilities housing thousands of PCs, have become increasingly important for hosting web services, such as Google, cloud computing and hosting virtualized services. Data centers are also important for high performance computing facilities which turn the power of thousands of PCs loose on difficult but important scientific and engineering computational problems. Data centers are an impressive technological wonder, with their energy consumption being an important issue affecting their location and cost of operation

Notes
- 1.
A kernel is the most basic part of most operating systems. It connects applications to data processing in the computer’s hardware. Kernel address space is used exclusively by the kernel, kernel extensions and most device drivers while user space is where the user applications reside and work.
- 2.
Middleware is software which connects application software to the operating system. Some types of middleware are eventually incorporated into newer versions of operating systems. An example of this migration is TCP/IP.
- 3.
Copy avoidance methods use less copying of data to memory by the operating system leading to higher data transfer rates. Zero copy methods make no copies.
- 4.
“Semantics” is the meaning of computer instructions—“syntax” is their format.
