Keyboards allow for easy input. Mouse control is typically provided by a track pad. Also contained within the device are the typical computer components such as a CPU, video card, and hard drive. In a laptop everything is included in one package. Although the desktop largely contains the same components, the parts are not as integrated.
A user has opened a word processor, typed the numbers 123456789, and stored the document as a file called report1. Which of the following determines, in part, what bits the computer stores in the file to represent the text typed into the report? c. Character set 7. A user has opened a calculator application, typed the numbers 123456789, and then done some math problem using this number. Which of the following determines, in part, what bits the computer stores in RAM to represent the number 123456789?
Evaluate Systems Architecture Name School Abstract The CPU is the brain of the computer. Throughout the evolution of computers, various inventors have come up with different architectures and designs for CPUs. It has to be connected to the rest of the components of a computer and communicates with them through signals carried by buses on the system board. This papers examines the organization and interconnection of the CPU and the rest of the components Table of Contents Abstract 1 CPU 1 VLIW (very long instruction word) and EPIC (Explicitly parallel instruction computer) 2 Main memory 3 Registers 3 Program counter 3 Instruction register 3 Memory address register and memory data register 3 Multiprocessing 4 References 4 CPU A CPU can be described using various characteristics. These include the memory addressing techniques, type of registers and their number, the design of its instruction set and others.
The CPU tells the RAM which address holds the data that the CPU wants to read 6. A user has opened a word processor, typed the numbers 123456789, and stored the document as a file called report1. Which of the following determines, in part, what bits the computer stores in the file to represent the typed into the report? C. Character set 7. A user has opened a calculator application, typed the numbers 123456789, and then done some math problem using this number.
This has led to a plethora of more or less standardized file structures for all imaginable purposes, from the simplest to the most complex. Most computer files are used by computer programs which create, modify or delete the files for their own use on an as-needed basis. The programmers who create the programs decide what files are needed, how they are to be used and (often) their names. Explain how an operating system manages multiple processes… Memory management is the function of a computer operating system responsible for managing the computer's primary memory. The memory management function keeps track of the status of each memory location, either allocated or free.
The actual machinery - wires, transistors and circuits is called hardware; the instructions and data are called software. All general purpose computers require the following hardware components: (i) Central Processing Unit (CPU): The ‘brain’ of the computer, the component that actually executes instructions. (ii) Memory : It enables a computer to store, at least temporarily, data and programs. (iii) Input device : Usually a keyboard or mouse is used to read data and programs into the computer. (iv) Output device: A display screen, printer, etc.
Introduction The PC that I chose is the HP Pavillion Touch-Screen All-in-One computer. The touch-screen feature of this computer is the main reason why I selected it, besides the other latest technological features it has, being that not many computers come touch-screen. The Mac model I chose for comparison is the iMac, being that it’s the newest model that is available, plus Apple doesn’t offer much of a diverse selection when it comes to the desktops. Processor The AMD A6-series processor on the HP computer is relatively fast, however it delivers much better graphics than the processor on the Mac computer. Whereas the processor on the Mac doesn’t produce as high-quality graphics, yet provides a little more speed.
Compare and Contrast Laptop Computers and Desktops Having to choose between a Laptop Computer or a desktop is difficult choice that one is faced especially if it is for personal use. Check out the advantages and disadvantages of both these models and consider all facts before deciding on one that suits you the best. Firstly laptops weigh very less and you can carry them around when you travel and work from anywhere. Secondly, Laptops are single units with all features built into it. The third point in its favor is that most of the professionals who are always on emails and finance and other executives who do a lot of data and number crunching prefer laptops for their work.
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?
There is a control unit, which manages the process of moving data and programs into and out of the memory, and also executes the programs instructions, one by one. There is an input and output which is the computers connection to the user. The arithmetic logic unit is responsible for carrying out calculations
