It also outlines key aspects of TQM including management commitment, continuous improvement, employee empowerment, customer focus, and supplier partnership.
History of computerMNButtThis document provides a history of computers from the earliest mechanical devices through modern electronic systems. It begins with a classification of computers by technology, capacity, operating principle, and other factors. The evolution of computers is then discussed in five stages: the mechanical era from 1623-1945 involving early calculators and analytical engines; the first electronic computers from 1937-1953 using vacuum tubes; the second generation from 1954-1962 utilizing transistors; the third generation from 1963-1972 featuring integrated circuits; and modern supercomputers. Key individuals and their inventions are highlighted throughout the development of computer technology.
Kryvyi Rih Mineral WaterKR_CDIZaporizhzhya region
The investment proposal is to analyze mineral water deposits in Kryvyi Rih, Ukraine and produce drinkable and therapeutic mineral water. Kryvyi Rih has a large population with growing demand for mineral water and local authorities support the project. The project requires analyzing water quality and compliance with standards. If successful, it would provide healthier drinking water options for residents and tax revenue. Key risks include the upfront costs of drilling, equipment, and licensing required.
Africa presentation Carson CastellanoNigeria has a long history dating back to the 9th century, and was a British colony from 1901 until gaining independence in 1960. It has over 250 ethnic groups and is evenly divided religiously between Christianity and Islam. Nigeria has experienced periods of military rule but is now a federal republic with its capital in Abuja and largest city of Lagos, and has a population of over 160 million, making it the most populous country in Africa.
Disc millMNButtThis presentation discusses disc mills, which are attrition-type mills used to grind or crush materials. It describes the history and working principles of disc mills, including their construction with a feed hopper, grinding discs, and discharge vessel. Disc mills can be single-wheeled, double-wheeled, or vibrating. They are commonly used in agriculture, food processing, chemical processing, mining, and recycling to grind or separate materials.
2. ИСТОРИЈА HDD-а
Прве тврде дискове је
направиоIBM1955. године[2]
(IBM 350 Disk Fileза свој
рачунарIBM 305), а изумео
их јеРејнолд Џонсон
(Reynold Johnson). Укупни
капацитет им је био 5
милиона 6-битних карактера
(3.75мегабајта). Имали су 50
дискова пречника 61cm са
100 површина за снимање.
Свака површина је имала по
100 трака. Имали су једну
једину главу (уместо једну по
површини) па је време
приступа било веома
дугачко.
3. Принцип рада
Магнетски диск своје деловање темељи на
физичким основамамагнетског пољаи својствима
феромагнетских материјала. При упису података на
њега користе се својства тзв. тврдих феромагнетских
материја да након што су магнетизоване спољашњим
пољем, остану магнетизоване и након што се
спољашње магнетско поље уклони. Тврди диск се
састоји од неколико плоча, обично од немагнетских
материјала, најчешће алуминијума или стакла. Те
плоче су премазане са танким слојем
феромагнетског материјала дебљине 10 до 20 nm
(као поређење, дебљина обичног копираног папира је
између 0,07 mm и 0,18 mm - 70.000-180.000 nm).На
тај магнетски материјал се обично још стави премаз
угљеникакао заштитни слој.
5. ВРСТЕ ТВРДИХ ДИСКОВА:
Постоје екстерни (спољни) и интерни (унутрашњи)
хард-дискови. Екстерни су великог капацитета (и
до неколикотерабајта), али зато могу бити велики
каокућиште рачунара. Интерни хард-дискови
знатно су мањих димензија, али зато располажу и
мањим капацитетима. Постоје магнетски интерни
хард-дискови (најчешћи 99,99% корисника)
ифлеш(енгл.Flash) интерни хард-дискови, који се
одликују великом брзином уписа/исписа података,
али су знатно скупљи. Флеш меморија се
првенствено користи за мале капацитете, и користи
се замеморијске картице.
6. ПЛОЧЕ ХАРД ДИСКА
Подаци се снимају
на једну или обе
површине сваке
плоче (диска), у
концентричним
круговима. Један
такав круг (на једној
површини) се
назива стаза, траг
или трака.
7. Повезивање тврдог диска са
рачунаром
Постоји јако много начина повезивања
хард-диска и рачунара (тачније матичне
плоче), а најчешћи су: ATA (ATA33,
ATA100, ATA133), UDMA, PIO, IDE, SATA, S-ATA2. Тренутно најбржи од
поменутих је S-ATA2 који се одликује
јако великом брзином преноса
података. Стандард повезивања за
екстерне хард-дискове је E-SATA.
8. ЗАНИМЉИВОСТ
Британац Џејмс Ховелс по
занимању IT стручњак
урадио је ствар због које се
сад горко каје.Џејмс је
бацио хард диск (HDD) на
ком је било сачувано
виртуелног новца званог
Bitconina који сад вреди
милионе долара...
Прецизније 7.500 виртуелне
валуте Bitcoina се налазило
на баченом Џејмсовом хард
диску чија данашња
вредност била око 7.5
милиона долара!
