  1. Special Purpose Computer - A Special Purpose Computer is the one that is designed to perform only one special task. The program or instructions set is permanently stored in such a machine. It does its single task very quickly and it cannot be used for any other purpose. These computers are often used to perform specific function such as.
  2. It defines the instruction as a machine language command to perform a specific task. It should be understandable by the computer system, hence it is a string of binary digits (0 and 1). Example: It may be issued to read data from the memory write data into the memory, etc. Generally, instruction is used to perform a single task
  3. Machine code or machine language is a set of instructions executed directly by a computer's central processing unit (CPU). Each instruction performs a very specific task, such as a load, a jump, or an ALU operation on a unit of data in a CPU register or memory. Every program directly executed by a CPU is made up of a series of such instructions
  4. The CPU is responsible to execute these machine instructions. In order to perform any task , the CPU has to repetitively perform a sequence of steps. These sequence of steps is called a machine cycle. The machine cycle is a part of the instruction cycle. The CPU might perform number of machine cycles to execute one single instruction
  5. For example, every computer requires a bus that transmits data from one part of the computer to another. II, Computer sizes and power. Computers can be generally classified by size and power as follows, though there is considerable overlap: Personal computer: A small, single-user computer based on a microprocessor
  6. CPU time = Instruction count x CPI x clock cycle time.

Computer software. Software is a program that enables a computer to perform a specific task, as opposed to the physical components of the system (hardware). This includes application software such. Instruction count is the number of native instructions—instructions written for that specific CPU—that must be executed by the CPU to achieve correct results with a given computer program. Users typically write programs in high-level programming languages—such as Java, C, C++, and C#—and then use a compiler to translate the high-level. Computer is an automatic machine. Automation is the ability to perform a given task automatically. Once the computer receives a program i.e., the program is stored in the computer memory, then the program and instruction can control the program execution without human interaction. Reduction in Paper Work and Cos

A program is a set of step-by-step instructions that directs the computer to do the tasks you want it to do and produce the results you want. Programming helps you understand computers. The computer is only a tool. If you learn how to write simple programs, you will gain more knowledge about how a computer works These machines provided a variety of instructions that may perform very complex tasks, such as string searching; they also generally used a number of different instruction formats of varying lengths. One of the advances in the development of high-performance microprocessors was the concept of reduced instruction set computers (RISC) operations. Every computer has its own unique instruction set. The ability to store and execute instructions, the stored program concept, is the most important property of a general-purpose computer. An instruction code is a group of bits that instruct the computer to perform a specific operation In a complex machine, having a part move more quickly just because system resources are available may be just as catastrophic as having it not move at all because the system is busy. Single-user, single task - As the name implies, this operating system is designed to manage the computer so that one user can effectively do one thing at a time Software is actually a computer program. To be more specific, a program is a set of step-by-step instructions that directs the computer to do the tasks you want it to do and to produce the results you want. A computer programmer is a person who writes programs. Most of us do not write programs, we use programs written by someone else

Accordingly, we can ignore a program generates a memory address. We are interested only in the sequence of memory addresses generated by the running program. The following is a summary of the six steps used to execute a single instruction. Step 1: Fetch instruction. Step 2: Decode instruction and Fetch Operands.

This is a consequence of previous work by Alan Turing on Turing machines , which we studies in Chapter 5

Classification of Computer According to Purpose Computer

A computer is a programmable device that can automatically perform a sequence of calculations or other operations on data once programmed for the task. It can store, retrieve, and process data. After executing an instruction, the CPU obtains (fetches) the (next) instruction at the address (location) given in the program counter. The fetched instruction is stored in the instruction register in the CPU and the program counter is increased to point to the next instruction in the memory . The fetched instruction (stored in the instruction register) is the executed (the CPU will do the. Computer is an electronic machine that makes performing any task very easy. In computer, the CPU executes each instruction provided to it, in a series of steps, this series of steps is called Machine Cycle, and is repeated for each instruction.One machine cycle involves fetching of instruction, decoding the instruction, transferring the data, executing the instruction EECC550 - Shaaban #3 Lec # 3 Winter 2011 12-6-2011 • For a specific program compiled to run on a specific machine (CPU) A, has the following parameters: - The total executed instruction count of the program. - The average number of cycles per instruction (average CPI). - Clock cycle of machine A • How can one measure the performance of this machine (CPU) runnin

You are given two implementations of the same Instruction Set Architecture (ISA): Machine Cycle Time CPI A 1 ns 2.0 - Instruction count will be the same - Hence, possible instructions to translate code to is the same on both machines o Therefore only one way to do i++ for example - Then, how can CPI be different? 3. 5% of a task/program. The computer processes the machine code to perform the corresponding tasks. A compiler should comply with the syntax rule of that programming language in which it is written. However, the compiler is only a program and cannot fix errors found in that program. So, if you make a mistake, you need to make changes in the syntax of your program Machine code is a very efficient way of taking a circuit and connecting it to a lightbulb, and then taking that lightbulb out of the circuit and switching the circuit over to a different lightbulb. Memory in a computer is highly necessary because otherwise to get your computer to do anything, you would need to type out everything (in machine code)

B. Application software is used to accomplish specific tasks other than just running the computer system. Application software may consist of a single program, such as an image viewer; a small collection of programs (often called a software package) that work closely together to accomplish a task, such as a spreadsheet o A replacement of the old machine with a new machine (with user-state migration and an optional full WIM image backup). New computer. Also called a bare metal deployment. This scenario occurs when you have a blank machine you need to deploy, or an existing machine you want to wipe and redeploy without needing to preserve any existing data All the human beings in this world communicate with each other by a language. Similarly, computer also needs some expression medium to communicate with others A computer follows the instructions given by the programmer to perform a specific job. To perform a particular task, programmer prepares a sequence of instructions, know as programmed Chapter 3.3 Computer Architecture and the Fetch-Execute Cycle . Von Neumann Architecture . The earliest computing machines had fixed programs. For example, a desk calculator (in principle) is a fixed program computer. It can do basic mathematics, but it cannot be used as a word processor or a gaming console

It is the simulation of natural intelligence in machines that are programmed to learn and mimic the actions of humans. These machines are able to learn with experience and perform human-like tasks There may be more to your instructions than just tasks. Some instructions have only a single task, but have many steps within that single task. For example, imagine a set of instructions for assembling a kids' swing set. In my own experience, there were more than 130 steps! That can be a bit daunting A PC is a small and relatively inexpensive computer designed for an individual use. PCs are based on the microprocessor technology that enables manufacturers to put an entire CPU on one chip. Personal computers at home can be used for a number of different applications including games, word processing, accounting and other tasks Involves only those tasks executing a communication operation. When a task performs a communication operation, some form of coordination is required with the other task(s) participating in the communication. For example, before a task can perform a send operation, it must first receive an acknowledgment from the receiving task that it is OK to.

In a basic computer, each instruction cycle consists of the following phases: Fetch instruction from memory. Decode the instruction. Read the effective address from memory. Execute the instruction. Input-Output Configuration.

The operations that the instructions perform are usually very simple. Only by writing a sequence of these simple operations, can you make the processor perform a specific task. However, writing a sequence of numeric codes is quite tedious (though that's how programming was done long ago), so the assembly programming language was created Hugh Pickens writes The advantages of RISC are well known — simplifying the CPU core by reducing the complexity of the instruction set allows faster speeds, more registers, and pipelining to provide the appearance of single-cycle execution.Al Williams writes in Dr Dobbs about taking RISC to its logical conclusion by designing a functional computer called One-Der with only a single simple. The quantum computer will in a sense act like the GPU in your laptop, doing certain specific tasks, like matrix inversion or optimization of initial conditions, a lot faster than the CPU alone. 3. Are machine-independent programs therefore programs written in a high-level language do not have to be reprogrammed when a new computer is installed. 4. Programmers do not have to learn a new language for each computer they program.
