Memory Parts of a computer How do computers work? Memory Parts of a computer

Parts of a computer The computer is made of Programs or instructions that tell the machine how to work = SOFTWARE e.g. Operating system, Word… Physical parts of the computer= HARDWARE e.g. monitor… & All the parts work together to make the machine work

Memory - Binary System Computers can only remember and read zeros and ones. Each character, number, symbol that you see on the computer screen is recorded by the computer as a combination of zeroes and ones. E.g. 01100010 = letter a

Memory units A combination of 8 zeroes and ones that represent a number o letter is called a bit. This is the smallest unit of memory Some units of memory 1024 bits 1 Byte (B) 1024 Bytes (B) 1 Kilobyte (KB) 1024 KB 1 Megabyte (MB) 1024 MB 1 Gigabyte (GB) 1024 GB 1 Terabyte (TB) 1024 TB 1 Petabyte (PB)

End of unit project Title: What are computers? Definition Computers that are part of our lives How does a computer work Binary system and storage (memory) units Parts of a computer What computers do for us Computers that do not look like computers
