What values can a single bit have?
A computer follows a program — a list of instructions — to work with data.
Which list matches the parts von Neumann described for a computing device in his 1945 EDVAC report?
A bit has to be stored in something real. Which of these could hold one bit?
A byte is eight bits. How many bits are there in 4 bytes?
Why was it a powerful idea to keep a computer's instructions in the same memory as its data?
Each bit can be 0 or 1. How many different patterns can a group of 3 bits make?
Computers typically store the letter 'A' as the bit string 01000001. What whole number does this binary pattern represent?
The EDVAC report separates 'the specific instructions given for and defining a particular problem' from 'the general control organs' that carry instructions out. Explain why this separation is what makes a machine general-purpose, and one cost it introduces.
