27. Machine Language

28. Low Level Language

29. High level Language

30. MACHINE LANGUAGE

31. It uses computer storage more efficiently

32. It takes less time to process in a computer than any other programming language

33. It is time consuming

34. It is very tedious to write

35. It is subject to human error

36. It is expensive in program preparation and debugging stages

37. LOW LEVEL LANGUAGE

38. usually defined by the hardware manufacturer, and is based on abbreviations (called mnemonics) that help the programmer remember individual instructions, registers, etc. An assembly language is thus specific to a certain physical or virtual computer architecture (as opposed to most high-level languages, which are usually portable).

39. assembler performs a more or less isomorphic translation (a one-to-one mapping) from mnemonic statements into machine instructions and data. (This is in contrast with high-level languages, in which a single statement generally results in many machine instructions.)

40. processor instructions, or to address critical performance issues. The following section of an assembly language program also adds overtime to base pay and stores the result in gross pay:

41. Load basepay

42. Add overpay

43. Store grosspay

44. It is more efficient than machine language

45. Symbols make it easier to use than machine language

46. It may be useful for security reasons

47. It is defined for a particular processor

48. Assemblers are difficult to get

49. clearer to humans, they are incomprehensible to computers until they are translated to machine language.

50. Compilers are easy to get
