This resource is aimed at students looking at Encryption methods, specifically the Vernam Cipher. This is a copy of Baudot code that students would need to use to carry out the logical XOR with their keyword to produce the cipher text for their encrypted message. Whilst they are not required to know Baudot code, being able to more easily recognise this in preparation for their exam is useful.

This help sheet is designed for students studying A-Level Computer Science and includes details about the common binary numbers that will occur when using 4 bit unsigned binary to represent fractional/decimal numbers.

This resource is aimed at students studying A-Level Computer Science and contains most of the common symbols they will come across when learning about Set Operations and Set Comprehension. This will save them time when constructing set comprehensions or set operations as they will be able to copy and paste the required symbols out of this document. It will also strengthen their understand of what each symbol means.

This resource is aimed at students studying GCSE Computer Science. The worksheet contains a space for students to write down the main steps required to calculate the file size of a given image file. It then contains 10 questions (3 of which are worked through) that require them to calculate the file size of the image. It also contains the associated answer sheet. NB: The measurements for KB, MB, GB have been used as multiples of 1000 as per the new 9-1 specifications.

This resource is aimed at students studying A-Level Computer Science and contains 56 conversion questions between Two's Complement Binary & Denary and between Denary &Two's Complement Binary. It also includes the associated answer document.

This is a resource aimed to be used with students in KS3 to test their ability to convert to and from Binary and Denary/Decimal numbers. Section 1 - Binary to Denary/Decimal The first section of the worksheet starts with getting students to convert an 8 bit binary number into its equivalent denary value. After they have complete these there are a couple of extension questions that get them to try and expand their understanding by finding out what the next column headings are for the binary numbers that come with 10 bits and then 12 bits. Section 2 - Denary/Decimal to Binary Once students have been shown the way to convert from Denary/Decimal into binary there are a series of conversions that they must carry out to create the binary string from the given denary/decimal numbers. If they finish the main section, there are 2 small extension sections that get students to try and develop their conversion skills by converting number that require 10+ bits. There is also one questions that requires them to use 16 bits. I have also included the answer sheet for both the conversions so you can go through the answers with the students in class.

This resource is aimed at students studying A-Level Computer Science and 20 questions on converting a given Fixed Point Binary number in Denary and a further 20 questions converting a given Denary number into a Fixed Point Binary number. It also includes the associated answer sheet.

This worksheet is designed to allow students to broaden their knowledge of the ASCII and Unicode character coding schemes. The worksheet contains several questions about the history of ASCII as well as some about how many bits it uses to represent data. The worksheet then moves onto looking at Unicode and getting the students to use the Unicode website to find and retrieve details about specific Unicode characters. The worksheet conclused with a 4 mark questions that asks them to discuss the advantages and disadvantages of ASCII & Unicode. This download also contains the accompanying answer sheet (for everything except the 4 mark question).

This resource is aimed at students studying A-Level Computer Science and contains 20 subtraction calculation questions that must be completed using Two's Complement Binary and the associated answer document.
