Von Neumann Computer Architecture Information engine room EssayThe Von Neumann Computer is a digital pc that storing the entropy in a single separate way and it usance a processing unit. A digital knowledge processing placement keeps its program in cultivation with its info as well. The Von Neumann Computer named after name of calculating machine scientist John von Neumann.5 Internal Comp atomic number 53nts Description of for each one components, how they be affiliated to Mother Board, diagram.Hard Disk Hard disk is a magnetized disk that allows you to store your calculating machine data, a leaden disk brood of several platters, which each individual platter is able to read and write. The hard disk is attached to the motherboard by ribbon cable (ATA66/100).Random approaching reposition (RAMIt is type of reckoner stock but it discharge be recovered randomly, RAM is very fast to read than any storage guile in a PC. As long as your reckoner is trial the data store in a RAM but when the computing device turns off, Ram will lose its data. The Ram committed to the motherboard by petite circuit, in the motherboard there is two circuit places which is one for inline computing machine storage and the blurb is duel inline computer memory.Processor Processor or Central Processing unit ( central processor) it is die of computer system and in easy way it is a brain of computer the origin of processor in a computer is to give a instruction for any computer program the mainframe computer is connected to the motherboard directly.Graphic Card It is a bridge between mainframe computer and other devices to send command and gets back the signal, the Graphic Card is connected throw the expansion slot which is in the Motherboard.5 External Components Description, how atomic number 18 they connected? Eg Ports, USB, etc. Diagram.Key Board keyboard is primary way to excrete with input you can use the keyboard to input text and data. When we pr ess a key, it presses a button, completing the circuit and allowing an amount of current to run with and keyboards atomic number 18 connected by USB cable or PS2.Mouse cabbage is device which lets you work with graphical objects that the computer displays on the screen. Mouse has one button or roundtimes cardinal buttons and it have scroll cast that enable user to scrolling long document or webpage. The Mouse is connected by USB cable or PS2.Printer It is a device that can print text or graphic that stored in a electronic form, and it connect to the PC by USB Port.Scanner It is a device that scans data or any text, printed page or photo you scan it to the computer and it connected to the computer by USB Port.Monitor A Monitor is alike a television but the difference is that monitor display the information produced by a computer, basically it is a screen display of a computer and it connect VGA port in a PC or in some PC by the Video card.Task 2 Describe the signs of the va rious types of internal memory of computerWhat is internal memory of computer?The internal memory of computer is also subtract of computer devices that recoding media that keep digital data used for computing for some interval of time.What are the major types of internal memory of computer? For each type of internal memory, explain how it works and what are its major characteristics there are types of computer internal memory which is Random Access Memory (RAM) and Read Only Memory (ROM).Random Access Memory (RAM) It is a unorthodox computer internal memory and it is a space that allows us to temporarily store data when a program is running. The contents are being lost when the computer is switched off it only holds data spell power is on.There are some major types of RAM which areRambus DRAM (RDRAM) is a serial memory technology that arrived in three flavours, PC600, PC700, and PC800. PC800 DRAM has doubled the maximum throughput of old, but a higher urge on and it use small ca pacitors to store each bit of memory in an forebodeable format that consists of rows and columns, DRAM designs with multiple channels.SIMM chips Single in-line memory modules (SIMMs) it is a type of solid state computer memory which is used peculiar(prenominal) for the mainframe computer lay away memory. The 72-pin SIMM has a notch among the contacts in the middle. An important characteristic of RAM is that the entire memory place can be accessed at almost the same speed.Read Only Memory (ROM) Is a mental of memory that store the data permanently and it cannot be removed, eventually every computer is coming with a small amount of ROM which enter of boot firmware, when we divide our computer the ROM chips will running hardware diagnostics that will loading the operating system into RAM.Cache The roll up will make our computer more skilled and better, your computer memory, cache is extremely fast memory that store data and the data is ready to hand(predicate) quickly and it gives quickest response to the processor.Virtual Memory The virtual memory task was to enable a process to operate or express the status of pages in its virtual address space.Task 3 beg off the purpose and manoeuvers of the system busses of a computer inform how the internal subsystems are linked through buses and where these buses could be found inside a computer.The computer internal subsystems are connect to the busses through wire inside the computer and the data transfer throw these from one segmentation to the another part of computer. Busses connect the entire computer component with the main memory and processor.Explain the run aways of control, data, and address busses. What is bus width and what is the effect of the bus width on the bus performance?The architecture of buses is a wire inside a computer which data is transfer from one part to another part inside the computer, the purpose of buses is to connect the entire computer component to the processor and to the c entral memory. Busses are dividing into two parts the Data busses and Address busses. The function of data busses is to transfer the data and the function of address busses is to give boot to data where to go. Bus width is a canal that information is menses when the bus width is wider it is beneficial for busses because more information can fall down in more speedy time.What is a motherboard chip set? With use of a diagram, explain what is the role and characteristics of the North and South Bridge of a motherboard.It is a specific chip in a computer that calls motherboard chipset. The Northbridge is centre of attention logical in a computer motherboard and its role is to hold communion with RAM, BIOS ROM, PCI and central processing unit. The South Bridge job is to manage the basic of input/ make These include all hard drive and expansion slots, USB, FireWire, RAID, audio codes, real-time system clock, system power management, interrupt controller, direct memory access (DMA) co ntroller, and non-volatile BIOS memory.Task 4 Describe, with the aid of diagrams, what are the components andthe structure of processor and how mainframe worksWhat is the CPU of a modern computer and what are the CPU components?The Central Processing Unit (CPU) is the brain of a computer that gives function to a computer programme. Every time when CPU doing a job there is a stored code in the computers memory that instructs the CPU what to do. CPU needs to decode the instruction code to find what it needs to do finish the task. After the CPU solve the code, the CPU will start to perform calculation and the result whether it store the result back in memory, to hard drive, or the computer display. The way that we can understand how effective a process is by the number of instruction that a CPU can execute per second.The CPU components areLogic or arithmetic unit (ALU) it performs calculations, there are four types of function that ALU do and it depends on these to perform and they are addition, subtraction, multiplication and division even registering and instruction.Register or the memory which stores the data, it tell CPU where the information is located, also its a temporary storage areas for instructions or data and they are not part of the memory. Register hold and transfer instructions. Register operate faster than a Ram, normally register assess by bit like 32 bits.Control unit which give direction to the data around the CPU by sending control signals and its job is to control the data that punish by the ALU, also the Control Unit keeping communicate with ALU and system memory.Use a diagram to explain the components of CPUCPU Components DiagramArithmetic Logic Unit (ALU)RegistersControl UnitInput windSecondary StorageOutput DeviceExplain shortly the capture Execute Cycle of CPU referring to its components and RAM.Fetch Execute Cycle of CPU it is an order of actions that the central processing unit (CPU) perform to execute each machine code instruct ion in a program. There are five register in the Fetch Execute Cycle which areThe Instruction Register that hold the solved and executed last instruction. The memory buffer register that use to get data from memory. The memory address registers that to be use when a word is transferred between memory and MBR. The accumulator register job is to hold the result of ALU for the time being and the programme predict that hold the address of the next instruction to be fetched from memory.
