OCR H446 1.4.3 Boolean logic and notation
Part 1 · H446 1.4.3 · Boolean algebra
OCR H446 1.4.3 opens with notation, and students who cannot turn a sentence into variables lose marks long before they reach a Karnaugh map. This first worksheet in the series builds that translation habit and separates AND, OR, NOT and XOR in the notation OCR uses. Students will: - represent two-state conditions as 0 and 1 using OCR operator symbols - distinguish an inclusive OR from an exclusive XOR in a described situation - define suitable variables for a written scenario before writing any expression - write a Boolean expression that keeps the scope of a negation correct - recall operator meanings without an answer bank in a closed-book check Inside: 6 explanation cells, 3 multiple-choice questions, 2 fill-in-the-blanks cells and 1 written answer. 16 marks, about 35 to 45 minutes. Series: H446 1.4.3 · Boolean algebra, part 1 of 11.
WorksheetOCR H446 1.3.2 Database foundations, tables and keys
Part 1 · H446 1.3.2 · Databases
OCR H446 1.3.2 opens with the vocabulary everything else depends on: database, table, field, record, and the primary, foreign and secondary keys that link them. This worksheet builds that model from a ticket-booking scenario so students can justify a key choice rather than recite a definition. Students will: - distinguish a flat file design from a set of linked relational tables - identify primary, foreign and secondary keys from where a field appears in a schema - explain the job each key does in the table it sits in - propose tables and keys for an unfamiliar equipment-loan scenario - recall the core definitions from memory with no answer bank available Inside: 7 explanation cells, 2 multiple-choice questions, 2 fill-in-the-blanks cells and 3 written answers. 27 marks, about 25 to 35 minutes. Series: H446 1.3.2 · Databases, part 1 of 13.
WorksheetOCR H446 1.2.1 Operating system purpose and functions
Part 1 · H446 1.2.1 · Systems software
The opening worksheet for H446 1.2.1 sets out what an operating system is for: hardware with very different jobs, many programs wanting it at once, and one managed layer coordinating the requests. It moves students from naming a function to explaining the mechanism behind it and the consequence for the user. Students will: - explain why a general-purpose computer needs an operating system at all - identify which operating-system function a described user action engages - describe memory, file, process, user and peripheral management with the purpose of each - explain how resource management keeps several open applications responsive - give two reasons applications reach hardware through the operating system rather than directly Inside: 5 explanation cells, 5 multiple-choice questions, 2 fill-in-the-blanks cells and 3 written answers. 30 marks, about 35 to 45 minutes. Series: H446 1.2.1 · Systems software, part 1 of 12.
