Computer hardware for business

Alfred is a long-time teacher and computer enthusiast who works with and troubleshoots a wide range of computing devices. This image illustrates the major components of a computer system.

While hardware and software components co-exist to make up the actual computer, the humanware component adds in the human face to bring the complete computer into a functional and productive existence.

When installed separately, each may be useful to an extent but incapable of achieving complete computing potential. Hardware and software need the human factor in order to make input and connectivity possible. These are computer system components that can be touched by the human hand. Examples include:. These parts are housed within the laptop or the desktop system-unit. For the desktop, however, the keyboard and mouse are attached and used externally.

A typical installation of computer hardware component includes a monitor, a computer, a keyboard, and mouse. The most important piece of hardware is the microprocessor chip, which is commonly known as the central processing unit CPU.

These chips are usually attached to the motherboard in these laptops. A component just as important is the disk drive. This is where computer data is stored. It is classified as secondary memory. Hard disk : This drive is mechanical by design and stores data on magnetic and metallic platters. A sudden power outage can lead to data loss or drive failure.

It must be used properly for the sake of data integrity and long lifespan. Solid state disk : This new type of disk drive stores data on flash memory chips and is less prone to erratic behavior. It is faster and reliable even in the event of sudden power outages. An illustration of various hardware components inside the system unit. Another vital part within a system is the motherboard. It provides communication and direct connectivity to devices throughout the computer.

Above is Apple's iMac computer, an example of a single unit computer set. It contains the system unit and monitor bundled together. Unlike the desktop and single unit computers, which have the mouse and keybaord as separate devices, the two are integrated within the laptop computer.

The software component refers to the instructions, programs, data, and protocols which run on top of hardware. It is also retained temporarily and persistently in primary and secondary hardware media. The random access memory chip is an example of primary hardware while the hard disk drive is an example of secondary hardware. An illustration of software componet running on a computer.

The system manages other software and devices inside the computer. The foremost example of system software is the operating system OS.

In a typical setup, the operating system is like the motherboard for software. It is the first thing that is installed, followed by applications and other software. This is designed for end-users to perform a specialized assignment in order to output useful information. An example would be a word processing application used to compose letters or brochures, such as Microsoft Word.

A collection of application software is bundled in a package that is commonly known as a software suite. A typical suite includes software for word processing, presentation, graphic design, and spreadsheet. The software component is stored on optical media, disk drives and cloud storage spaces. Malware is short for mal icious soft ware, which is a generic term that refers to exploitative code designed by criminals and black hat hackers to maim normal operations of a computer.

Malware attacks can result in data loss and hacker access to private information. Affected computers can also be converted into zombies and used in a bigger mission of criminal activities like launching denial of service attacks DOS and spreading spam. Malware scripts are delivered to the computer as viruses, trojans, rootkits, keyloggers, worms, or through email and websites as adware, spyware, ransomware and scareware. These are tools used by developers to create all kinds of software like Windows OS and Word processing.

Also called languages, they are used to write source codes, debug errors, maintain and create new software for computers and write malicious scripts like viruses and trojans. The humanware component refers to the person that uses the computer. More specifically, it is about the individual that makes hardware and software components productive.

Typically, a great deal of testing is done on software packages and hardware parts to ensure they enhance the end-user experience to aid in creating documents, musical and video recordings, and all forms of raw and finished data. A baby using a computer is one cute example of humanware. Even after purchasing the freshest ingredients and the finest pots and pans, there will not be a good meal without a chef.

Both hardware and software are complemented by the works of a human to produce a fully functional computer system. I am touched with your article. Perfectly done. I like the comparism, the arrnagement and everything involved in this article.

Nice article. I am not techy but your article was easy for me to follow. I particularly like the comparison in the end to kitchen utensils, recipes and chefs.

What is a Computer System Unit? A computer system unit is the enclosure that contains the main components of a computer. It is also referred to as a computer case or tower. Definition A typical desktop computer consists of a computer system unit, a keyboard, a mouse, and a monitor. The computer system unit is the enclosure for all the other main interior components of a computer. It is also called the computer case, computer chassis, or computer tower. Cases are typically made of steel or aluminum, but plastic can also be used.

A computer is a complex machine. While most of it works on a microscopic level, it certainly has recognizable macroscopic components that contribute to its uses. A computer can be used to do just about anything from simple calculations to preparing reports to sending rockets into space to simulating the spread of cancer in body organs. And yet, for all that complexity, the building blocks of the average computer are easy enough for anyone to understand.

INTRODUCTION TO COMPUTER HARDWARE

2. Computer Software

 - Ключ - это первичное, то есть простое число. Подумайте. Это не лишено смысла. Джабба сразу понял, что Сьюзан права. Энсей Танкадо сделал карьеру на простых числах. Простые числа - главные строительные блоки шифровальных алгоритмов, они обладали уникальной ценностью сами по .

Его обстановка напоминала домашнюю - мягкий ковер, высокотехнологичная звуковая система, холодильник, полный напитков и всяческой еды, маленькая кухня и даже баскетбольное кольцо. В отношении шифровалки в АНБ сложилась своеобразная философия. Нет смысла вбухивать миллиарды долларов в дешифровальный компьютер и одновременно экономить на тех, кто работает на этой превосходной технике.

Он не знал, как зовут этого человека. - Deutscher, ja. Вы немец.

Блестящий замысел. Выходит, Стратмор был зрителем теннисного матча, следящим за мячом лишь на одной половине корта. Поскольку мяч возвращался, он решил, что с другой стороны находится второй игрок.

Она пробовала снова и снова, но массивная плита никак не реагировала. Сьюзан тихо вскрикнула: по-видимому, отключение электричества стерло электронный код. Она опять оказалась в ловушке. Внезапно сзади ее обхватили и крепко сжали чьи-то руки. Их прикосновение было знакомым, но вызывало отвращение.

Молодой программист из лаборатории Белл по имени Грег Хейл потряс мир, заявив, что нашел черный ход, глубоко запрятанный в этом алгоритме. Черный ход представлял собой несколько строк хитроумной программы, которые вставил в алгоритм коммандер Стратмор. Они были вмонтированы так хитро, что никто, кроме Грега Хейла, их не заметил, и практически означали, что любой код, созданный с помощью Попрыгунчика, может быть взломан секретным паролем, известным только АНБ. Стратмору едва не удалось сделать предлагаемый стандарт шифрования величайшим достижением АНБ: если бы он был принят, у агентства появился бы ключ для взлома любого шифра в Америке.

 - Если бы ты не нашел черный ход в Попрыгунчике, мы могли бы взломать любой шифр, вместо того чтобы полагаться на ТРАНСТЕКСТ. - Если бы я не нашел черный ход, - сказал Хейл, - это сделал бы кто-то. Я спас вас, сделав это заранее. Можешь представить себе последствия, если бы это обнаружилось, когда Попрыгунчик был бы уже внедрен.

Прикинув, что такси развивает миль восемьдесят - чуть ли не вдвое больше его скорости, - он сосредоточил все внимание на трех ангарах впереди. Средний. Там его дожидается лирджет.

 Сюда, мистер Беккер. Быстрее. Беккер повернулся и побежал, но успел сделать только один шаг.

Само ее существование противоречило основным правилам криптографии. Она посмотрела на шефа. - Вы уничтожите этот алгоритм сразу же после того, как мы с ним познакомимся.

Посмотрим, вернулся ли. Разумеется, на ее экране замигал значок, извещающий о возвращении Следопыта. Сьюзан положила руку на мышку и открыла сообщение, Это решит судьбу Хейла, - подумала .
