Week 4: Computer Architecture CIS-106 Intro to Info Technology Abstract Computer architecture and its history are important to understanding how computers work. The basic building block to today’s modern day computers is the Von Neumann architecture. There are different types of functions within the Von Neumann architecture that have helped create an efficient design and allow computers to perform multiple functions rather than being used for one specific purpose. The Von Neumann model uses memory, system buses, and Boolean operators to communicate programs and perform functions. Week 4: Computer Architecture A computer is an electronic device that operates under the control of instructions that are stored in memory.
The unit can compare numbers, letters, or special characters. The computer can then take action based on the result of the comparison. It then has a memory unit which allows the CPU via the operating system to calculate the amount of memory needing to be allocated to each programme and where to put the memory in use if unallocated. The processor can also control backing storage this is sometimes knows as secondary storage this is the name for all other data storage devices in computer i.e. a hard drive, etc.
Relocation, sharing, physical organization, protection logical. What kind of memory address does a central processing unit (CPU) generate? Logical address What kind of memory address does a memory management unit (mmu) generate? Physical address What is the process of loading a process from secondary memory into primary memory? Input/ output channel from transferring data Homework -What are three main purposes and operating system?
Unit 1 Assignment 1 PT1420T Walter Kobylak Learning Objectives and Outcomes * Describe the role of software for computers. Software programs are used for performing functions with a computer. * Identify the hardware associated with a computer. Motherboard, CPU, Processor, hard drive or internal storage device, graphics adapter, keyboard, mouse. * Describe how computers store data.
In this architecture, various tasks are founded on binary instructions that are taken from a storage device. The data is then transmitted by the CPU (this is referred to as the fetch-execute cycle). Von Neumann is accredited for conceiving and assembling computers founded on three attributes: (1) that the computer is comprised of four main sub-systems: memory, ALU (Arithmetic / Logic Unit), Control Unit, Input / Output and System (I/O), (2) that programs are kept in memory while executing; and (3) that data / computer instructions are implemented consecutively. Von Neumann met with wide acclimations regarding the stored program computer with the components of memory and the control unit (Karwatka, 2005). These features are utilized today in all computers and many
