علوم الحاسوب لـ O Level / IGCSE
منهج واحد برمزين: O Level 2210 وIGCSE 0478، بالورقتين نفسيهما ولغة Pseudocode نفسها. كل موضوع أدناه لك أيًّا كان رمزك، ولا يختلف إلا جدول الامتحانات.
محتوى الدراسة هنا بالإنجليزية، لأن Cambridge تضع امتحاناتها وتصحّحها بالإنجليزية. اسأل AskZ وسيشرح لك أي موضوع بالعربية.
Paper 1
Computer Systems
1h 45m75 درجة50%
Data Representation
Everything is numbers. Learn how binary, hexadecimal, text, images and sound are stored and how data is compressed.
Data Transmission
How data travels — serial/parallel, simplex/duplex, USB, packets, error checking and encryption.
Hardware
The CPU and Von Neumann architecture, the fetch–decode–execute cycle, input/output devices, storage and virtual memory.
Software
System vs application software, the operating system, interrupts, and how high-level languages become machine code.
The Internet and Its Uses
Internet vs World Wide Web, URLs, HTTP/HTTPS, browsers, cookies, blockchain, cyber security threats and how to stop them.
Automated and Emerging Technologies
Automated systems with sensors, microprocessors and actuators; robotics; and artificial intelligence including expert systems and machine learning.
Paper 2
Algorithms, Programming and Logic
1h 45m75 درجة50%
Algorithm Design and Problem-Solving
Program development life cycle, decomposition, flowcharts and pseudocode, standard algorithms (searching, sorting, totalling, counting, max/min), validation and testing with trace tables.
Programming
The core skills: variables, constants, data types, input/output, selection (IF/CASE), iteration (FOR/WHILE/REPEAT), procedures, functions, string handling, arrays and file handling — in pseudocode and a high-level language.
Databases
Single-table databases: fields, records, data types, primary keys and SQL queries with SELECT, FROM, WHERE, ORDER BY, SUM and COUNT.
Boolean Logic
Logic gates (NOT, AND, OR, NAND, NOR, XOR), logic circuits, truth tables and logic expressions.
