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.

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.

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. The code can be machine-level code or the code written for an operating system.

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. Applications may be connected with the computer and its system software or may be published separately, and may be coded as proprietary or open-source. Operating system is defined as a system software that manages computer hardware and software resources and provides common services for computer programs. All cpplication softwareomputer programs require an operating system to function. Operating system controls computer's hardware, run the computer's programs and organizes files.

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. A set of instructions that drives computer to do stipulated tasks is called a program.

Computer hardware and software

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.

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.

Computer hardware includes the physical parts of a computer , such as the case , [1] 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.

Want to know what hardware is in your computer? Become a computer pro with our quick guide to these essential components and their roles. Quite simply, computer hardware is the physical components that a computer system requires to function. It encompasses everything with a circuit board that operates within a PC or laptop; including the motherboard, graphics card, CPU Central Processing Unit , ventilation fans, webcam, power supply, and so on. Although the design of hardware differs between desktop PCs and laptops due to their differences in size, the same core components will be found in both. Without hardware, there would be no way of running the essential software that makes computers so useful.

Беккер рванулся. Вобрав голову в плечи, он ударил убийцу всем телом, отшвырнув его на раковину. Со звоном разбилось и покрылось трещинами зеркало. Пистолет упал на пол. Оба противника оказались на полу.

Code: The Hidden Language of Computer Hardware and Software

Она оказалась в тоннеле, очень узком, с низким потолком. Перед ней, исчезая где-то в темноте, убегали вдаль две желтые линии. Подземная шоссейная дорога… Сьюзан медленно шла по этому туннелю, то и дело хватаясь за стены, чтобы сохранить равновесие.

EDU И далее текст сообщения: ГРОМАДНЫЙ ПРОГРЕСС. ЦИФРОВАЯ КРЕПОСТЬ ПОЧТИ ГОТОВА. ОНА ОТБРОСИТ АНБ НАЗАД НА ДЕСЯТИЛЕТИЯ. Сьюзан как во сне читала и перечитывала эти строки.

Он подумал, дома ли Сьюзан.

Он так торопился, что не заметил побелевших костяшек пальцев, вцепившихся в оконный выступ. Свисая из окна, Беккер благодарил Бога за ежедневные занятия теннисом и двадцатиминутные упражнения на аппарате Наутилус, подготовившие его мускулатуру к запредельным нагрузкам. Увы, теперь, несмотря на силу рук, он не мог подтянуться, чтобы влезть обратно.

 - Может, вы знаете имя этой женщины. Клушар некоторое время молчал, потом потер правый висок. Он был очень бледен.

Ну и ловок, подумала Сьюзан. На все у него готов ответ. - Отпусти меня! - попросил Хейл.  - Я ничего не сделал.

Мысли Сьюзан прервал громкий звук открываемой стеклянной двери. Она оглянулась и застонала. У входа стоял криптограф Грег Хейл. Это был высокий мужчина крепкого сложения с густыми светлыми волосами и глубокой ямкой на подбородке.

Ее мысли прервал шипящий звук открываемой пневматической двери.
