1a) A memory unit has 28-bit address lines and 64-bit input/output data lines. How many bytes of data can this memory hold? How many words does it contain, and how large is each word?

b) A memory unit consists of 32M words of 16-bit each. How many bits wide address lines and input-output data lines are needed to access this memory?

c) A memory unit consists of 512K bytes of data. How many bits wide address lines are needed to access this memory if the word size is 16 bit? If the word size is 64 bit?

A digital computer has a memory unit with 32 bits per word. The instruction set consists of 147 different operations. All instructions have an operation code part (opcode) and two address fields: one for a memory address and one for a register address. This particular system includes eight general-purpose, user-addressable registers. Registers may be loaded directly from memory, and memory may be updated directly from the registers. Direct memory-to-memory data movement operations are not supported. Each instruction stored in one...

NWS620S Tutorial 1: Symmetric Encryption - DES Encryption is the translation of data into a secret code so that only authorised entities can read it. Encrypting data is considered a very effective way of achieving data security. To access encrypted data, you must have access to a secret key that enables you to decrypt it. Unencrypted data is called plain text; encrypted data is referred to as cipher text. There are two types of encryption: • Symmetric encryption • Asymmetric...

Use Python 3.8: Problem Description Many recipes tend to be rather small, producing the fewest number of servings that are really possible with the included ingredients. Sometimes one will want to be able to scale those recipes upwards for serving larger groups. This program's task is to determine how much of each ingredient in a recipe will be required for a target party size. The first inputs to the program will be the recipe itself. Here is an example recipe...
