HARDWARE

What is hardware? The entire physical device in the computer system.

Donanım Nedir? Input devices CPU Storage devices Output devices

Input Devices Input is any information put into a computer. Keyboard Mause Scanner Modem (I/O) Optical reader Barcode reader Cameras/ webcam Microfon Touchpad

Output devices Output is any information that a computer produces. Common output devices are Monitors Touch screens, projectors Printers Speakers

Storage Devices Digital storage devices allow you to save your work. Common storage devices are: Hard Disk Floppy disk USB Memory CD-ROM DVD Blu Ray Disc

Data Storage Devices Hard Disk Stores data permanently on a computer.

Hard Disk Speed of hard disk, RPM (Roll Per Minute) Exp: 5200 Rpm, 7200 Rpm etc…

Data Storage Devices USB Flash Bellek USB = Universal Serial Bus Flash memory is a type of memory that can be written over and over again. The structure of flash memories is electronic. There is no moving part in it.

Data Storage Devices CD They provide only one time writable / readable environment using laser technology. (You can write rewritable CD more than one) They can be read by devices called CD-ROM drivers.

Data Storage Devices DVD The first priority of DVD was "Digital Video Disk". The main reason for this is that the first applications appeared in the field of video. But after a while, it was understood that the data storage applications were also important and the DVD started to be used as "Digital Versatile Disk".

Data Storage Devices Blu Ray Disc It helps to store the new generation high definition (HD) video on a single disc while also helping to store very large amounts of data.

Data Storage Devices Blu Ray Disc A single-layer Blu-ray disc can store more than two hours of HDTV quality or about 13 hours of standard definition video with a capacity of 25 GB. The double layer format has a data storage capacity of 50 GB.

Data Storage Units Bit 1 Bit 0 ya da 1'den (kapalı devre=0, açık devre=1) oluşur. Byte Bir Byte = 8 Bit tir. KB 1024 Byte = 1 KiloByte [KB] MB 1024 KB = 1 MegaByte [MB] GB 1024 MB = 1 GigaByte [GB] TB 1024 GB = 1 TeraByte [TB] PB 1024 TB = 1 PetaByte [PB] EB 1024 PB = 1 ExaByte [EB]

Veri Saklama Birimleri ZB 1024 EB= 1 Zettabyte [ZB] YB 1024 ZB = 1 YottaByte [YB] BB 1024 YB = 1 BrontoByte [BB] GpB 1024 BB = 1 Geopbyte [GpB]

Data storage devices and – units Exp. Floopy disk 1,44 MB CD 700 MB DVD 4,5 GB USB 256 MB 8 GB 32 GB Harddisk 320 GB 500 GB 1 TB

İşlemci Nedir? Merkezi İşlem Birimi (MİB) = Central Processing Unit (CPU) Bilgisayarın beyni diyebiliriz.

İşlemci Nedir? Central Processing Unit - also called “The Chip”, a CPU, a processor or a microprocessor. CPU or microprocessor is often described as the brain of a computer. Performs arithmetic and logical operations by processing data from various hardware devices. Translates them into a language that other devices can understand, and sends the data to the related device.

İşlemci Nedir? İşlemcide gerçekleştirilen tüm işlemlerin zamanında yapılıp yapılmadığını belirlemek için bir “işlem saati” bulunmaktadır. Bu saatin salınımları, saniyede bir milyon döngü (Megahertz) şeklinde ölçülür. 1000 MHz=1GHz dir ve salınım sayısı arttıkça işlemcinin hızı da artar.

Mainboard The motherboard is the base card of the entire system. Other cards (graphics card, modem, etc.) are inserted into the extension ports on the motherboard.

New generation motherboard

Memory Bellek, bilgisayarda bir programla ilgili bütün komut ve verilerin işlem görmek üzere depo edildiği, değişik işlemler sırasında oluşan ara ve sonuç bilgilerinin saklandığı kayıt ortamdır.

RAM (Ramdom Access Memory) Bellek Nedir? It holds the data even when the computer is turned off. ROM (Read Only Memory) “Waiting room” for computer’s CPU. Holds instructions for processing data, processed data, and raw data. If Computer is turned off, data is cleared RAM (Ramdom Access Memory)

Sound Card It enables to produce of sound by using digital sound data produced by computer. Allows these sounds to be transferred to external media such as speakers.

Graphic Card It is a card that enables the production of images using the digital image data produced by the computer and the transfer of these images to the external environment such as the monitor.

Modem Internal Modem External Modem A modem is a device that is used to connect internet via a telephone network. There are two types: Internal Modem External Modem

ADSL ADSL= Asymmetric Digital Subscriber Line = Asimetrik Sayısal Abone Hattı provide high-speed data, voice and video communications over copper wires used for existing telephones. Mevcut telefonlar için kullanılan bakır teller üzerinden yüksek hızlı veri, ses ve görüntü iletişimini aynı anda sağlayabilen bir modem teknolojisidir.

ADSL Modem without cable There are two types; ADSL Modem with cable ADSL Modem without cable

Ethernet Card It is used to exchange data between two computers or to connect to a network.
