2.3. Introduction to Computers

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.

Software is defined as the virtual programs that run on your computer; that is, operating system, internet browser, word-processing documents, etc. Although a computer can function only when both hardware and software are working together, the speed of a system will largely rely on the hardware used.

When building up a new computer, or simply replacing old parts, you may need to know the specific hardware in your computer. The purpose of this guide is therefore to help you understand the inner-workings of your computer.

The motherboard is at the center of what makes a PC work. It houses the CPU and is a hub that all other hardware runs through. The ports on the motherboard will also help you define what other hardware will be compatible with your computer, such as what type of RAM and graphics card you can use. Although the motherboard is just one piece of circuitry, it is home to another one of the most important pieces of hardware: the processor.

The CPU Central Processing Unit or processor is responsible for processing all information from programs run by your computer. This means that a processor advertising a high GHz rating will likely perform faster than a similarly specified processor of the same brand and age.

The role of RAM is to temporarily store on-the-fly information created by programs and to do so in a way that makes this data immediately accessible.

The tasks that require random memory could be; rendering images for graphic design, edited video or photographs, multi-tasking with multiple apps open for example, running a game on one screen and chatting via Discord on the other.

Find out how much memory your computer needs. The hard drive is a storage device responsible for storing permanent and temporary data. This data comes in many different forms, but is essentially anything saved or installed to a computer: for example, computer programs, family photos, operating system, word-processing documents, and so on. Find out more about hard drives and how they work.

There are two different types of storage devices: the traditional hard disk drive HDD and the newer solid state drives SSD.

Hard disk drives work by writing binary data onto spinning magnetic disks called platters that rotate at high speeds, while a solid-state drive stores data by using static flash memory chips.

Find out more about computer storage and how solid state drives work. Especially important for 3D rendering, the GPU does exactly what its name suggests and processes huge batches of graphic data. As opposed to the basic on-board graphic capabilities that PC motherboards supply, dedicated graphics cards interface with the motherboard via an expansion slot to work almost exclusively on graphic rendering. This also means you can upgrade your graphics card if you want to get a bit more performance from your PC.

Not only this, but modern GPUs fulfil a broad computational workload beyond just rendering, making them an extension to the central processing unit.

A power supply unit, commonly abbreviated as PSU, does more than just supply your computer with power. It is the point where power enters your system from an external power source and is then allocated by the motherboard to individual component hardware. Not all power supplies are made equally however, and without the right wattage PSU your system will fail to work. Computers that are used for highly intensive tasks such as graphic design or gaming will require more powerful components and thus will need a bigger PSU to cater to this additional need.

Not only do you guard yourself against system failure, you also future-proof yourself against needing a new PSU when you upgrade to more powerful PC components. Understanding your computer and its hardware components can prove very useful when the time comes to upgrade or replace any parts, or when building a computer.

Should a problem arise with the internal workings of your computer, you will have a better understanding of the importance of each component, the need for them to be in good working condition and how to go about solving any issues.

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.


Any kind of computers consists of HARDWARE AND SOFTWARE. Hardware: system and some fundamental utilities such as disk formatters, file managers.


2.3. Introduction to Computers

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.

The computer technology that allows us to develop three-dimensional virtual environments VEs consists of both hardware and software. The current popular, technical, and scientific interest in VEs is inspired, in large part, by the advent and availability of increasingly powerful and affordable visually oriented, interactive, graphical display systems and techniques. Graphical image generation and display capabilities that were not previously widely available are now found on the desktops of many professionals and are finding their way into the home.

Но Чатрукьян отказывался прислушаться к голосу разума. У нас вирус. Я звоню Джаббе. Когда он попытался обойти Стратмора, тот преградил ему дорогу. Лестничная площадка, на которой они стояли, была совсем крохотной. Они сцепились. Перила были невысокими.

 Плевал я на Стратмора! - закричал Чатрукьян, и его слова громким эхом разнеслись по шифровалке. - Мистер Чатрукьян? - послышался сверху звучный возглас. Все трое замерли. Над ними, опираясь на перила площадки перед своим кабинетом, стоял Стратмор. Какое-то время в здании слышался только неровный гул расположенных далеко внизу генераторов.

 - Дайте мне угадать: наш номер вам дал приятель. Сказал, чтобы вы обязательно нам позвонили. Я прав. Сеньор Ролдан уловил некоторое замешательство на другом конце провода.

Кроме того, оказавшись на улице без заложницы, он обречен. Даже его безукоризненный лотос беспомощен перед эскадрильей вертолетов Агентства национальной безопасности. Сьюзан - это единственное, что не позволит Стратмору меня уничтожить. - Сьюзан, - сказал он, волоча ее к лестнице, - уходи со. Клянусь, что я тебя пальцем не трону.

Стратмор подошел еще ближе. Он хотел прикоснуться к ней, но не посмел. Услышав имя Дэвида, произнесенное вслух, Сьюзан дала волю своему горю. Сначала она едва заметно вздрогнула, словно от озноба, и тут же ее захлестнула волна отчаяния. Приоткрыв дрожащие губы, она попыталась что-то сказать, но слов не последовало.

Преодолев треть ступенек, он почувствовал какое-то движение у подножия лестницы. Стратмор что-то задумал.
