What are the differences between these directives in MIPS

• .space
  
  reserves n bytes of memory. egarr: .space 100
  
  
• .byte
  
  store n values ​​in consecutive bytes of memory. egnum: .byte 0x01, 0x03
  
  
• .word
  
  store n 32-bit words in memory. egval: .word 10, -14, 30
  
  
• .asciiz
  
  stores a string in memory with a null terminator. egstr: .asciiz "Hello, world"
  
  
• .ascii
  
  stores a string in memory without a null terminator. egstr: .ascii "Hello, world"
  
  
• .align
  
  aligns the following data on a byte boundary 2^n
  
  . for example .align 2
  
  aligns the next value on a word boundary. On the other hand, if n is 0, justification is turned off until the next data segment.
