An introduction to computer systems, networking and security in GCSE computer science CO438 / A24
Summary
Take your first steps towards teaching GCSE computer science and establish a foundational knowledge base of concepts, terminology and classroom practice. Find out how the components of computer systems interlink and how these can then be connected together to form a network.
Learn about the different components of computer hardware, including devices not instantly recognisable as computers.
Who is it for?
This course is designed for teachers of KS3 and KS4 computing.
What topics are covered?
01 | Computer systems - here you’ll learn about the breadth of hardware devices many of which will be familiar, such as keyboards, monitors and printers. You’ll understand how computers store, process and transmit data and the essential roles of the central processing unit and computer memory. Terms like ‘8 bit’, ‘500 gigabyte drive’ or ‘megabit broadband’ are in common usage – this session explains these terms and more.
02 | Hardware - further develop your understanding of key hardware components by learning how they function together.
03 | Memory - Computers need to memorise data, during this session you'll explore how computer systems use different types of memory including cache memory, RAM and ROM.
04 | Networks - in the modern era almost all computers are part of a network. You’ll learn the essentials of how, and why, computers are networked locally, or globally through the internet. You’ll also find out about everyday internet services such as email and the worldwide web.
05 | Protocols - learn how network protocols are used to communicate over a network.
06 | Cyber-security - networks bring risks as well as benefits. This session will demystify some internet dangers such as phishing, viruses and distributed denial-of-service (DDoS) attacks
