CPU viết tắt của chữ Central Processing Unit (tiếng Anh), tạm dịch là đơn vị xử lí trung tâm. CPU có thể được xem như não bộ, một trong những phần tử cốt lõi nhất của máy vi tính. Nhiệm vụ chính của CPU là xử lý các chương trình vi tính và dữ kiện.
In the 40s the first computers were built. The very first models were ‘programmed’ by means of huge connection boards. Soon the program was stored in computer memory, introducing the first programming languages. Because in those days computer use was very expensive, it was obvious to have the programming language resemble the architecture of the computer as close as possible. A computer consists of a central processing unit and a memory. Therefore a program consisted of instructions to modify the memory, executed by the processing unit. With that the imperative programming style arose.
It is a common practice in computer science for the words “computer” and “processor” to be used interchangeably. More precisely, “computer” refers to the central processing unit (CPU) together with an internal memory. The internal memory or main storage, control and processing components make up the heart of the computer system. Manufacturers design the CPU to control and carry out basic instructions for their particular computer.

Chapter 4 - The central processing unit. This chapter presents an overview of the CPU (central processing unit), which functions as the "brain" of the personal computer. Like the human brain, a CPU is a complicated, highly integrated component performing many simultaneous functions. Understanding the principles that underlie the workings of the microprocessor is critical to understanding the computer and its operation.

A second problem often observed in developing countries in the credit-investment process is
that loans are allocated according to political considerations or ties between bank managers
and the corporate sector. This practice is problematic for two reasons: First, even if the central
bank can create liquidity and the financial sector as a whole is thus not be constrained by a
lack of base money, banks in developing countries are often weakly capitalized. Legal
minimum capital-adequacy ratios hence limit the overall amount of loans provided by the

In the wake of the EU’s greatest enlargement, this book explores the
adaptation of the constitutions of Central and Eastern Europe for membership
in the European Union. In response to the painful past, these new
constitutions were notably closed to the transfer of powers to international
organisations, and accorded a prominent status to sovereignty and independence.
A little more than a decade later, the process of amending these
provisions in view of the transfer of sovereign powers to a supranational
organisation has proved a sensitive and controversial exercise....

A mathemalical model is presented that describes heat and moisture transfer during the holpressing of MDF. The model includes conduction of heat between the press platens and the central layer of the mattress, phase change of water from the adsorbed to the vapor state and the convective heat and mass transfer through the edges of the mattress. This approach results in a three-dimensional unsleady-state problem in which the properties of the wood fibers, water and the wood-water system are dependent on temperature, mattress moisture content and steam pressure.
Oversight practices are directed to improving the way the organization manages all projects. Oversight or governance in multiproject organizations supports the trend of integration over the last three decades. Centralization of project management activities became imperative as projects became more numerous and became the means to implement organization strategy.
