COMPUTER ORGANISATION is nothing but assembling the various parts of a computer (hardware). Here are some of those parts which are defined to understand easily for those who are preparing for Competitive exams.
►An Arithmetic Logic Unit (ALU) is a digital circuit that performs integer arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit of a computer.
►Control Unit is responsible for controlling the overall operations of computer. It coordinates the sequence of execution of instructions and controls the overall functioning of the computer.
►The first computer architecture was introduced by John Von Neumann (1970)
►Personal computers use a number of chips mounted on a main circuit board called Motherboard.
►The CPU is fabricated as a single Integrated Circuit (IC) chip. It is also known as the Microprocessor.
►Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system to support more than one processor and/or the ability to allocate tasks between them.
►The organisation and interconnection of the various components of a computer system is known as Computer Architecture.
►A CPU can directly understand the Machine Language.
