Question 1

What is CPU?

Answer 1

Central Processing Unit

Question 2

What does CPU do?

Answer 2

Coordinates a computer’s operations by regulating the computer with control data OR it fetches data

Question 3

What’s the second physical component besides CPU?

Answer 3

Arithmetic and logic unit which are the mathematical operations

Question 4

What is the organization of CPU?

Answer 4

To fetch the data, there needs to be a program that stores the instructions/input into the memory.

Question 5

What the fuck is fetching data?

Answer 5

When the CPU takes input from the main memory to make the next sequence.

Question 6

What is the second part of an organization of CPU?

Answer 6

DECODE! Once the input is turned into a number the control unit makes it into an electronic signal.

Question 7

Main memory/RAM?

Answer 7

Random access memory that holds information and sequences of instructions. It erases every time the computer is off.

Question 8

How is the memory held in RAM?

Answer 8

Switches labeled 0 or 1 (binary). 8 of these are called a byte. Part of memory access to track data.

Question 9

Why do you need RAM and secondary storage?

Answer 9

BECAUSEEEEEE
RAM is quick and accessible by the CPU and secondary storage is permanently saved data

Question 10

What is secondary storage in CPU organization?

Answer 10

It can hold data for long periods without power.

Question 11

Tell me about the common types of secondary storage.

Answer 11

Disk drive (stores magnetically), solid-state drive (in a case), external drives (moves to another computer), USB etc (copies of data)

Question 12

What are the devices to input data?

Answer 12

Any data collected from outside: keyboard, mouse, scanner

Question 13

What are the devices to output data?

Answer 13

Any data sent outside: graphics, reports, lists

Question 14

What is software? you noob

Answer 14

Programs that run on a laptop

Question 15

Riddle me this, whats a program then?

Answer 15

It’s a set of instructions (special language) a computer follows to perform a task.

Question 16

What are the instructions to the program?

Answer 16

The instructions are called the algorithm. Needs to be in binary to be read by computer.

Question 17

What are the two parts of software?

Answer 17

Operating systems: programs that manage the hardware and its processes that multitask and divide CPU across programs.
Application Software: programs that are useful to the user by creating a better environment (games, word processor, spreadsheets)

Question 18

Is JAVA process dependent or non?

Answer 18

NON because it doesn’t need an assembler.
