Von Neumann Computer Structures Information Technology Essay

The Von Neumann Computer is a digital pc that storing the data in a single independent way and it use a processing unit. A digital computer maintains its program in education using its data as well. The Von Neumann Computer named after name of computer scientist John von Neumann.

5 Internal Components: Information of each components, the way they are linked to Mother Table, Diagram.

Hard Drive: Hard disk drive is a magnetic drive that allows someone to store your personal computer data, a hard disk contain several platters, which every individual platter is able to read and write. The hard disk drive is linked to the motherboard by ribbon cable television (ATA66/100).

Random Access Memory space (RAM:

It is type of computer memory but it could be accessed randomly, Memory is very fast to learn than any storage device in a Laptop or computer. So long as your personal computer is running the data store in a Ram memory however when the computer becomes off, Ram will lose its data. The Ram connected to the motherboard by small circuit, in the motherboard there may be two circuit places which is one for inline recollection and the second is duel inline storage area.

Processor: Processor or Central Processing Product (CPU) it is part of computer system and in easy way this can be a brain of computer the job of CPU in a computer is to give a instruction for just about any computer program the cpu is connected to the motherboard directly.

Graphic Greeting card: It really is a bridge between processor chip and other devices to send command line and gets back again the sign, the Graphic Credit card is linked throw the development slot machine which is in the Motherboard.

5 Exterior Components: Information, how are they connected? Eg Slots, USB, etc. Diagram.

Key Panel: keyboard is key way to talk to input; you may use the keyboard to suggestions word and data. Whenever we press a key, it presses a button, doing the circuit and allowing some current to run through and keyboards are connected by USB cable tv or PS2.

Mouse: mouse is device which enables you to work with visual objects that the computer shows on the display. Mouse button has one button or sometimes three switches and it have scroll steering wheel that enable consumer to scrolling long document or web page. The Mouse is connected by USB cable television or PS2.

Printer: It really is a device that can printing text or graphic that stored in a digital form, and it hook up to the Personal computer by USB Interface.

Scanner: It really is a tool that scans data or any wording, printed site or photo you check out it to the computer and it connected to the computer by USB Interface.

Monitor: A Screen is like a television however the difference is the fact that monitor display the information produced by some type of computer, basically this is a screen display of any computer and it connect VGA port in a PC or in a few Computer by the Video recording card.

Task 2 Describe the characteristics of the various types of inner storage area of computer:

What is inside ram of computer?

The internal ram of computer is also part of computer devices that recoding multimedia that keep digital data used for processing for some interval of energy.

What are the major types of internal storage area of computer? For each type of inner memory, explain how it works and what exactly are its major characteristics

There are types of computer interior ram which is Random Access Ram (RAM) and Read Only Memory space (ROM).

Random Access Ram (RAM): It is a momentary computer internal recollection and it is a space which allows us to briefly store data when a program is operating. The material are being lost when the computer is switched off it only holds data while vitality is on.

There are some major types of Ram memory which are


Rambus DRAM (RDRAM): is a serial memory space technology that found its way to three flavours, Personal computer600, Laptop or computer700, and Personal computer800. Computer800 DRAM has doubled the maximum throughput of old, but an increased velocity and it use small capacitors to store each little bit of memory within an addressable format that includes rows and columns, DRAM designs with multiple stations.

SIMM potato chips: Single in-line storage modules (SIMMs) it is a type of solid status computer ram which can be used particular for the processor chip cache storage. The 72-pin SIMM has a notch one of the contacts in the centre. An important feature of RAM is the fact that the entire memory space place can be reached at almost the same swiftness.

Read Only Memory (ROM): Is a kind of storage that store the data once and for all and it can't be removed, eventually every computer is arriving with a tiny amount of ROM which saved of boot firmware, when we start our computer the ROM chips will operating hardware diagnostics that will launching the operating system into Ram memory.

Cache: The cache can make our computer more skilled and better, your personal computer memory, cache is extremely fast storage area that store data and the info is obtainable quickly and it offers quickest response to the CPU.

Virtual Memory: The digital memory activity was to permit a process to use or set up the position of web pages in its virtual address space.

Task 3 Explain the reason and functions of the machine busses of the computer:

Explain how the internal subsystems are connected through buses and where these buses could be found inside a computer.

The computer inner subsystems are hook up to the busses through wire inside the computer and the data transfer chuck these in one part to the another part of computer. Busses hook up the whole computer component with the main memory and cpu.

Explain the functions of control, data, and address busses. What's "bus width" and what is the result of the "bus width" on the bus performance?

The architecture of buses is a wire inside a computer which data is copy from one part to some other part inside the computer, the goal of buses is to hook up the entire computer element of the processor also to the central ram. 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 provide way to data where you can go. Bus width is a canal that information is flowing; when the bus width is wider it is effective for busses because more info can stream in more fast time.

What is a motherboard "chip placed"? With use of an diagram, explain what is the role and characteristics of the North and South Bridge of the motherboard.

It is a specific chip in your personal computer that calls motherboard chipset. The Northbridge is primary logical in a computer motherboard and its own role is to hold communication with Memory, BIOS ROM, PCI and CPU. The South Bridge job is to control the basic of source/output These include all hard drive and expansion slots, USB, FireWire, RAID, sound rules, real-time system clock, system ability management, interrupt controller, immediate memory access (DMA) controller, and non-volatile BIOS storage.

Task 4 Describe, using diagrams, what are the components and

the framework of CPU and how CPU works:

What is the CPU of today's computer and what are the CPU components?

The Central Control Product (CPU) is the brain of an computer that gives function to a pc programme. Each time when CPU performing a job there's a stored code in the computer's recollection that instructs the CPU how to proceed. CPU must decode the teaching code to find what it needs to do finish off the task. Following the CPU solve the code, the CPU will start to perform computation and the result whether it store the effect back in recollection, to hard drive, or the computer screen. The way that we can know how powerful an activity is by the amount of instruction a CPU can do per second.

The CPU components are:

Logic or Arithmetic product (ALU) it functions calculations, there are four types of function that ALU do and it depends on these to perform and they're addition, subtraction, multiplication and section even registering and instruction.

Register or the memory which stores the data, it inform CPU where in fact the information is situated, also from the temporary storage space areas for instructions or data and they are not part of the memory. Register carry and transfer instructions. Register operate faster than a Ram, normally enroll assess by little like 32 pieces.

Control device which give direction to the info about the CPU by mailing control signals and it's job is to control the data that executed by the ALU, also the Control Unit keeping talk to ALU and system memory.

Use a diagram to explain the components of CPU

Explain quickly the Fetch Execute Routine of CPU referring to its components and Memory.

Fetch Execute Circuit of CPU it can be an order of actions that the central control device (CPU) perform to perform each machine code instruction in a program. You will discover five register in the Fetch Execute Cycle which can be:

The Teaching Register that hold the solved and executed last teaching. The storage area buffer register that use to get data from recollection. The storage address registers that to be use whenever a word is transferred between memory space and MBR. The accumulator job is to hold the consequence of ALU for the moment and the programme counter that hold the address of another education to be fetched from memory space.
