- Concept of Hardware and Software
Von-Neumann computer consists of two main components: memory and CPU. This concept has not yet been overcome and even the latest computers still come from von-Neumann architecture. An application software is a computer program designed to perform a group of coordinated functions, tasks, or activities.

What do flashlights, the British invasion, black cats, and seesaws have to do with computers? In CODE, they show us the ingenious ways we manipulate language and invent new means of communicating with each other.
And through CODE, we see how this ingenuity and our very human compulsion to communicate have driven the technological innovations of the past two centuries. Using everyday objects and familiar language systems such as Braille and Morse code, author Charles Petzold weaves an illuminating narrative for anyone who's ever wondered about the secret inner life of computers and other smart machines.
It's a cleverly illustrated and eminently comprehensible story—and along the way, you'll discover you've gained a real context for understanding today's world of PCs, digital media, and the Internet.
No matter what your level of technical savvy, CODE will charm you—and perhaps even awaken the technophile within. Book Site. Want to know the elevation AMSL at any spot all over world?

Computer Hardware Books
Computer hardware is any physical device used in or with your machine, whereas software is a collection of programming code installed on your computer's hard drive. In other words, hardware is something you can hold in your hand, whereas software cannot be held in your hand. You can touch hardware, but you cannot touch software. Hardware is physical , and software is virtual. While software may come on a CD or DVD , the disc is the storage medium for the programming code that makes up the software. The disc is not the actual software.
The modern world offers lots of readily available online resources for learning. Wikipedia, Google, news sources, millions of Web sites and blogs, even YouTube, offer access to information in nearly any subject that triggers your curiosity and interest. Nonetheless, I continue to believe that for a deep understanding of something, nothing beats the integrated approach and focus of an old-fashioned printed-on-paper textbook. When I open a new book, in any subject, the first thing I want to know is what the book has to offer that makes it worth my while to read it. The information systems and technology fields are wonderfully exciting places to be!
Computer Software. • Software – a set of programs and procedures that are intended to perform some tasks on a computer system; makes computer useful.

Computer Hardware: Hardware refers to the physical components of a computer. Computer Hardware is any part of the computer that we can touch these parts. These are the primary electronic devices used to build up the computer. Computer Software: Software is a collection of instructions, procedures, documentation that performs different tasks on a computer system.

Concept of Hardware and Software
Computer hardware includes the physical parts of a computer , such as the case ,  central processing unit CPU , monitor , mouse , keyboard , computer data storage , graphics card , sound card , speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is " hard " or rigid with respect to changes, whereas software is "soft" because it is easy to change. Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware,it is typically directed by the software to execute and command or instructions. The template for all modern computers is the Von Neumann architecture , detailed in a paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers , a control unit containing an instruction register and program counter , a memory to store both data and instructions , external mass storage , and input and output mechanisms.
The term hardware refers to mechanical device that makes up computer. Examples of hardware are CPU, keyboard, mouse, hard disk, etc. Computer hardware is a collection of several components working together. Some parts are essential and others are added advantages. Computer hardware is made up of CPU and peripherals as shown in image below.
Hardware refers to the physical elements of a computer. This is also sometime called the machinery or the equipment of the computer. Examples of hardware in a computer are the keyboard, the monitor, the mouse and the central processing unit. However, most of a computer's hardware cannot be seen; in other words, it is not an external element of the computer, but rather an internal one, surrounded by the computer's casing tower. A computer's hardware is comprised of many different parts, but perhaps the most important of these is the motherboard.

Желаю веселого уик-энда. Чатрукьян заколебался. - Коммандер, мне действительно кажется, что нужно проверить… - Фил, - сказал Стратмор чуть более строго, - ТРАНСТЕКСТ в полном порядке. Если твоя проверка выявила нечто необычное, то лишь потому, что это сделали мы. А теперь, если не возражаешь… - Стратмор не договорил, но Чатрукьян понял его без слов.
- Что еще это может. Иначе Танкадо не отдал бы ключ. Какой идиот станет делать на кольце надпись из произвольных букв.
Наверное, за ним тянется красный след на белых камнях. Он искал глазами открытую дверь или ворота - любой выход из этого бесконечного каньона, - но ничего не. Улочка начала сужаться.
Под главной клавиатурой была еще одна, меньшего размера, с крошечными кнопками. На каждой - буква алфавита. Сьюзан повернулась к .
Сьюзан надеялась, что Стратмору не придется долго возиться с отключением ТРАНСТЕКСТА. Шум и мелькающие огни в шифровалке делали ее похожей на стартовую площадку ракеты. Хейл зашевелился и в ответ на каждое завывание сирены начал моргать.
