What is a computer

• Electronic device
• Tool
• Not a magic black box

15

Primary Storage Unit

• Read Only Memory
• Random Access Memory
• Basic Input/Output System

20
Memory Organization

• Two circuit states correspond to 0 and 1.
• Bit (short for binary digit) refers to a single 0
  or 1. Bit patterns represent both the computer
  instructions and computer data.
• 1 byte 8 bits
• 1 KB 1024 bytes
• 1 MB 1024 x 1024 1,048,576 bytes
• Word amount of memory that computer views
  
• as a single unit

25
Secondary (Auxiliary) Storage

• Disk Drives
• Hard/fixed/internal
• Floppy
• CD
• Removable Media

26
Remember

• Memory (primary storage) is different from disk
  space (secondary storage)!

27
Hardware vs Software

• Hardware
• Physical Components
• Anything you can touch!

• Software
• Anything that is not hardware
• programs

28
Various types of software

• Operating Systems
• Application Software
• Games
• Utilities

29
Algorithm vs Program

• Algorithm Step-by-step process for solving a
  problem in a finite time.
• Program Algorithm translated into a language

30
Remember!

• All programs are algorithms, but not all
  algorithms are programs!
