1 Evoluția calculatoarelor

2 Primul calculator electronic binar:
Evolutia Calculatoarelor Electronice Primul calculator electronic binar: 1937 (-1942) ABC (Atanasoff-Berry Computer) Peste 300 de tuburi electronice, memorie dinamica...

3 Primul calculator programabil: 1941(1943) - Z1, Z2,Z3 (Konrad Zuse)
Evolutia Calculatoarelor Electronice Primul calculator programabil: 1941(1943) - Z1, Z2,Z3 (Konrad Zuse) Contine peste 2000 releie electromagnetice Implimentează aritmetica binară în virgulă mobilă cu lungimea cuvîntului de 22-biti (adunarea, scăderea, înmulțirea, înpărțirea, radical)

4 1943 – Colossus (Tommy Flowers)
Evolutia Calculatoarelor Electronice 1943 – Colossus (Tommy Flowers) Calculator electronic digital, folosit de criptoanaliștii britanici la decriptarea mesagelor interceptate dintre Comandamentul German. Este format din1600 tuburi electronice

5 Evolutia Calculatoarelor Electronice
1946 – ENIAC Electronic Numerical Integrator And Computer (John Mauchly și J. Presper Eckert) Primul calculator electronic de uz general (decimal) ENIAC avea de tuburi electronice, 7200 diode cu cristal, 1500 releie, rezistoare, de condensatoare. Cîntarea 27t și consuma 150kW

6 Evolutia Calculatoarelor Electronice
1949 – EDVAC Electronic Discrete Variable Automatic Computer (John Mauchly și J. Presper Eckert) Spre deosebire de ENIAC, era un calculator binar și funcționa dupa un program stocat în memorie – 1000 cuvinte de 44 biți.

7 Evolutia Calculatoarelor Electronice
1949 – EDSAC Electronic Delay Storage Automatic Calculator (Mauris Willkes) EDSAC utiliza numere binare de 17 sau 35 biți și un acumulator de 71 biți. Setul de instrucțiuni includea instrucțiunile de adunare, deplasare, încarcare/stocare a regisrului, salt condiționat, citire bandă, tiparire caracter, rotungire acumulator, nop și stop

8 Evolutia Calculatoarelor Electronice
1952 – IBM 701 Un modul logic pe tuburi electronice

9 Evolutia Calculatoarelor Electronice
– IBM 7000 Mainframe construit pe tranzistore, memorie pe inele feromagnetice

10 (Programmed Data Processor-1) DEC
Evolutia Calculatoarelor Electronice 1959– PDP-1 (Programmed Data Processor-1) DEC

11 1974– Scelbi – 8N (Nate Wadsworth, Bob Findley )
Evolutia Calculatoarelor Electronice 1974– Scelbi – 8N (Nate Wadsworth, Bob Findley ) CPU : Intel 8008, 500kHz RAM: 1KB, (15KB)

12 Evolutia Calculatoarelor Electronice
1975– Altair 8800

13 1976 – Apple I (Steve Wozniak)
Calculator personal 1976 – Apple I (Steve Wozniak) CPU : MOS 6502, 1MHz RAM: 4KB, (expandabila prin card extern) Graphic: 40x24 charracters

14 Calculator personal Model Procesor An IBM PC I-8088 1981 IBM XT 1983 3270 PC IBM Portable 1984 IBM AT 80286 AT/370 3270 AT 1985

15 Calculator Personal Placa de baza IBM PC

16 Calculator Personal Expanded Memory Board

17 Evolutia Calculatoarelor Electronice
Vector -06C (Donat Temirazov și Alexandr Solov) Procesor КР580ВМ80А (Intel8080), 3MHz RAM – 64KB (din care pină la 32KB - video), ROM – 2K
