The Central Processing Unit (CPU): Crash Course Computer Science 7. (ii) The logic unit of the ALU is concerned with logical operations such as comparison (Greater than (>), less than (<), equal to (=) etc), bitwise logic operations like AND, OR, XOR etc. To make our CPU well bring in our ALU and RAM we made in the previous two episodes. (i) The ALU performs basic such as addition, subtraction, multiplication, division and so on. The ALU is a fundamental building block of the CPU of a computer. In this chapter you can find the Central Processing Unit (CPU) - Computer & IT for SSS 2 SSS 2 Notes, Videos & Tests defined & explained in the simplest way. 2 students are using this for SSS 2 preparation. The ALU is a digital circuit that performs arithmetic and logical operations. The Complete Chapterwise preparation package of Computer & IT for SSS 2 is created by the best SSS 2 teachers for SSS 2 preparation. All the functions of the CPU are stored in a component called the chip. in Information and Computer Science & Systems Programming. principal centralize, centralise verb to bring under one control. Question: Why is a computers central process unit (CPU or processor) critically. It is sometimes called the Central Processor or simply the Processor.Ī computer can have more than one CPU this is called multiprocessing. belonging to or near the centre ( eg of a town). It is also called the brain of the computer. The Central Processing Unit carries out each instruction of the program in sequence, perform the basic arithmetical, logical, and input/output operations of the system.Īlso, the Central Processing Unit (CPU) is the part of a computer that thinks, calculates and carries out instruction. The Central Processing Unit (CPU): Is the portion of a computer system that executes the instructions of a computer program, and is the primary element carrying out the functions of the computer or other processing device.
