✨ Cutubka 1: Waa Maxay Computer?

Computer waa qalab elektaroonik ah oo loo adeegsado in lagu keydiyo, lagu farsameeyo, laguna soo saaro macluumaad (information).
Waxa uu qabtaa hawlo badan oo dadka ka caawiya:

• Xisaabinta xogta
• Kaydinta files-ka
• Daabicista (printing)
• Soo saarida natiijooyin (output)
• Hagaajinta shaqooyinka maalinlaha ah

Computer wuxuu shaqeeyaa isagoo raacaya amaro (commands) uu ka helo user-ka ama software lagu rakibay.

✨ Cutubka 2: Taariikhda Computer-ka – Xaaladihii Uu Soo Maray

Computer-ka maanta aan isticmaalno wuxuu soo maray dhowr jiil (generations):

1️⃣ Jiilka Koowaad (1940–1956)

• Waxay adeegsadeen vacuum tubes
• Aad bay u weynayeen
• Aad bay koronto u cunayeen
• Tusaale: ENIAC, UNIVAC

2️⃣ Jiilka Labaad (1956–1963)

• Waxay isticmaaleen transistors
• Yaryar, degdeg & kalsooni badan
• Koronto yar ayay isticmaalaan

3️⃣ Jiilka Saddexaad (1964–1971)

• Waxaa soo baxay Integrated Circuits (IC)
• Computer-ku wuu yaraaday
• Waxay bilaabeen shaashado & keyboard

4️⃣ Jiilka Afraad (1971–Hadda)

• Waxaa lagu shaqeeyaa Microprocessors
• Waa kuwa aan isticmaalno maanta
• Intel & AMD ayaa hormuud ah

5️⃣ Jiilka Shanaad (Hadda & Mustaqbalka)

• Artificial Intelligence (AI)
• Quantum computers
• Voice recognition & automation

✨ Cutubka 3: Kumaa Hindisay Computer-ka?

Computer-ka waxaa markii ugu horreysay concept-kiisa soo hindisay:

🔹 Charles Babbage (Father of Computer)

• Waxay keeneen fikradda Analytical Engine
• Waxaa la dhihi karaa waa aabbaha computer-ka

🔹 Ada Lovelace

• Waa qofkii ugu horreeyay ee qorta barnaamij computer (program)
• Waxaa loogu yeeraa first programmer in history

🔹 Alan Turing

• Aabbaha Artificial Intelligence
• Soo saaray Turing Machine
• Door weyn ku lahaa jabintii sirta Nazi-ga WWII

✨ Cutubka 4: Noocyada Computer-ka (Types of Computer)

Computer-yada waxaa lagu kala qori karaa dhowr qeybood:

🔹 1. Supercomputer

• Computer-ka ugu xoogga badan
• Waxay xalliyaan xisaabo culus
• NASA, cilmi-baaris & militariga ayaa isticmaala

🔹 2. Mainframe Computers

• Waxaa isticmaala shirkado waaweyn
• Waxay maamulaan xog malaayiin qof

🔹 3. Minicomputers

• Dhexdhexaad ah
• Waxay ka shaqeeyaan hawlo gaar ah

🔹 4. Microcomputers (Personal Computers)

Kuwa aan isticmaalno:

• Desktop
• Laptop
• Tablet
• Smartphone

✨ Cutubka 5: Qaybaha Computer-ka (Parts of a Computer)

Computer-ka wuxuu ka kooban yahay laba qaybood waaweyn:

1️⃣ Hardware

Qayb kasta oo aad taaban karto waa hardware, sida:

• Monitor (Shaashad)
• Keyboard
• Mouse
• CPU Case
• Hard Disk
• RAM
• Motherboard
• Printer
• Speakers

2️⃣ Software

Ma taaban kartid, waa programs-ka ama barnaamijyada:

• Windows
• macOS
• Linux
• MS Word, Excel
• Browsers (Chrome, Edge)

✨ Cutubka 6: Hardware vs Software – Maxay Kala Yihiin?

Hardware	Software
Wax aad taaban karto	Lama taaban karo
Qalabka jirka ah	Barnaamij
Tusaale: Keyboard, RAM	Tusaale: Windows, Chrome
La’aantiis wax shaqo ah ma qabto	Hardware-ga ayuu shaqo siinayaa

Labadaas midba midka kale ayuu u baahan yahay si uu u shaqeeyo.

✨ Cutubka 7: Fahamka Qoto Dheer ee CPU, RAM & ROM

🔥 CPU (Central Processing Unit)

• Waa maskaxda computer-ka
• Waxaa loo yaqaan processor
• Hawsha uu qabto:
  • Xisaabinta
  • Falanqaynta xogta
  • Fulinta amarada
• Qaybaha CPU:
  • ALU (Arithmetic Logic Unit)
  • CU (Control Unit)
  • Registers

🔥 RAM (Random Access Memory)

• Waa xasuusta temporary
• Marka computer-ku dansho → xogta waa tirmaataa
• Waxay ka dhigtaa computer-ka degdeg
• Waxaa loo isticmaalaa:
  • Furista apps
  • Kaydinta xogta ku-meel-gaarka ah
• Inta RAM badan → waa inta uu computer-ku ka dheereeyo

🔥 ROM (Read Only Memory)

• Waa xasuusta permanent
• Xogta kama tirmato xitaa haddii computer-ka la dansho
• Waxay kaydsataa:
  • BIOS
  • Firmware
• Waa “maskaxda bilowga” oo computer-ka tusaysa sida loo shido

✨ Cutubka 8: Gunaanad – Muhiimadda Computer-ka Maanta

Computer-ku wuxuu noqday:

• Qalab shaqo
• Qalab waxbarasho
• Qalab xirfad sameyn
• Qalab isgaarsiineed
• Qalab ciyaaro & madadaalo

Dunida maanta cid walba waxay u baahan tahay xirfado computer ifaysa — laga bilaabo shaqooyinka online-ka ilaa barashada xirfadaha horumarka sida programming, design, editing, iyo waxbarashada casriga.
