Global and local variables (2.2.1)
This post covers the following from the specification (2.2.1): (a) Programming constructs: sequence, iteration, branching. (b) Recursion, how it can be used and compares to an iterative approach. (Skipped for now) (c) Global and local variables. (d) Modularity, functions and procedures, parameter passing by value and by reference. (e) Use of an IDE to develop/debug a program. (f) Use of object oriented techniques. (Skipped for now) What is scope? Scope is the area in which a

Types of Processors (1.1.1 - 1.1.2)
This post covers: CISC and RISC Von Neumann, Harvard and Contemporary Architectures Multicore and Parallel Systems Pipelining GPUs 1.1 - Von Neumann and Harvard Von Neumann archetecture shared memory space is used for oth the instrucitons and date stored. It can do one insturciton at a time, Von Neumann uses registers for fast access to instrucitons and data. Harvard is diferent, instructions and memory are stored seperately and each have thier own memory address, compared to
