Show understanding of the need for interrupts Show understanding of the basic Von Neumann model for a computer system and the stored program concept (program instructions and data are stored in main memory and instructions are fetched and executed one after another) Describe the stages of the fetch-execute cycle, including the use of registers and buses

Show understanding of how data are kept safe when stored and transmitted, including: use of passwords, both entered at a keyboard and biometric use of firewalls, both software and hardware, including proxy servers use of security protocols such as Secure Socket Layer (SSL) and Transport Layer Security (TLS) use of symmetric encryption (plain text, cypher text and use of a key) showing understanding that increasing the length of a key increases the strength of the encryption Show understanding of the need to keep online systems safe from attacks including denial of service attacks, phishing, pharming. Describe how security can be applied to real-life scenarios including, for example, online banking, shopping or safeguards when carrying out online transactions .

MS EXCEL Practical Test for Year 7/8 and 9

Lesson Objectives: Lesson 1 All of you will… Draw simple shapes using the turtle Understand the use of different commands such as move forward, backward, left, right Most of you will… Use computational thinking skills to look for repeating patterns and include them in your programming Lesson 2 Understand the motion commands with Python turtle module Understand the use of Variables and how to assign them values. Understand the use of different commands such as PenUp/PenDown, goto, forward, backward, left, right and t.begin_fill() & t.end_fill(), t.goto(x,y), t.setposition(x,y), t.pensize(value), t.setheading(value), t.color(‘green’) Lesson 3 What you’re aiming for in this lesson is to: familiarize yourself with the various code statements play with the code and learn how to change and adapt it. For example, if you have the code for a small red square, you should be able to change it to make a big yellow square. be able to use the code we have developed for various shapes to create a picture.

Please make sure you practice geometric shapes below using python programming (turtle graphics) and make sure you learn the name of each geometric shape. Please click the link below to start your practical tasks https://trinket.io/

Lesson Objectives: 5.1 Operating System Explain why a computer system requires an Operating System (OS)Explain the key management tasks carried out by the Operating System:Including memory management, file management, security management, hardware management (input / output / peripherals), process management.Show understanding of the need for typical utility software provided with an Operating System:Including disk formatter, virus checker, defragmentation software, disk contents analysis/disk repair software, file compression, back-up software.Show understanding of program libraries: Including: • software under development is often constructed using existing code from program libraries• the benefits to the developer of software constructed using library files, including Dynamic Link Library (DLL) files. Learning Objective: 5.2 Language Translators Show understanding of the need for:• assembler software for the translation of an assembly language program• a compiler for the translation of a high-level language program• an interpreter for translation and execution of a high-level language programExplain the benefits and drawbacks of using either a compiler or interpreter and justify the use of each Show awareness that high-level language programs may be partially compiled and partially interpreted,such as JavaDescribe features found in a typical Integrated Development Environment (IDE)Including:• for coding, including context-sensitive prompts• for initial error detection, including dynamic syntax checks• for presentation, including prettyprint, expand and collapse code blocks• for debugging, including single stepping, breakpoints, i.e. variables, expressions, report window

6.1 Data Security 6.2 Data Integrity Explain the difference between the terms security , privacy and integrity of data Show appreciation of the need for both the security of data and the security of the computer system Describe security measures designed to protect computer systems, ranging from the stand alone PC to a network of computers. Including user accounts, passwords, authentication techniques such as digital signatures, firewall, antivirus software, anti spyware, encryption. Show understanding of the threats to computer and data security posed by networks and the internet. Including malware (virus, spyware), hackers, phishing, pharming. Describe methods that can be used to restrict the risks posed by threats Describe security methods designed to protect the security of data Including encryption, access rights

10.1 Data Types and Records: Select and use appropriate data types for a problem solution including integer, real, char, string, Boolean, date (pseudocode will use the following data types: INTEGER, REAL, CHAR, STRING, BOOLEAN, DATE, ARRAY, FILE) Show understanding of the purpose of a record structure to hold a set of data of different data types under one identifier Write pseudocode to define a record structure. Write pseudocode to read data from a record structure and save data to a record structure 10.2 Arrays: Use the technical terms associated with arrays (Including index, upper and lower bound) Select a suitable data structure (1D or 2D array) to use for a given task Write pseudocode for 1D and 2D arrays Write pseudocode to process array data Sort using a bubble sort Search using a linear search 10.3 Files: Show understanding of why files are needed Write pseudocode to handle text files that consist of one or more lines 10.4 Introduction to Abstract Data Types (ADT): Show understanding that an ADT is a collection of data and a set of operations on those data. Show understanding that a stack, queue and linked list are examples of ADTs Describe the key features of a stack, queue and linked list and justify their use for a given situation Use a stack, queue and linked list to store data (You will not be required to write pseudocode for these structures, but they should be able to add, edit and delete data from these structures) Describe how a queue, stack and linked list can be implemented using arrays
