This document outlines the course content for a Higher Computing course, which is divided into 3 main units: Computer Systems, Software Development, and Artificial Intelligence. The Computer Systems unit covers topics like data representation, computer structure, networking, and computer software. It discusses how numbers, text, images, and other data are stored in binary and converted between binary and decimal. It also covers graphics representation, storage calculations, and compression techniques. Assessment includes end of unit tests, coursework tasks, and a written exam.

1. Higher Computing Mr Arthur

5. Data Representation 100 billion switches per sq. cm

26. Storage Capacities 0 or 1 = 1 bit 8 bits = 1 byte 1024 bytes = 1 Kilobyte 1024 Kilobytes = 1 Megabyte 1024 Megabytes = 1 Gigabyte 1024 Gigabytes = 1 Terabyte

33. BIT Map Graphics SCREEN MEMORY PIXEL MEMORY REQUIRED 8 BITS X 8 BITS = 64 BITS = 8 BYTES Bit Map = the graphic is made up from a series of pixels

39. Bit Depths Bit Depth = 2 bits 01 10 11 00
