CARRY OUT MEASUREMENTS AND CALCULATION

WEEK 6 DAY 4

OBJECTIVES: This module is intended to select appropriate measuring instrument to achieve required outcome, obtain accurate measurements for job, perform calculation needed to complete task using the four mathematical fundamental operations addition (+), subtraction (-) multiplication (x), and division (÷), use calculation involving fractions, percentages and mixed numbers to complete workplace tasks, self-check and correct numerical computation for accuracy, and read instruments to the limit of accuracy of the tool.​

​Lesson Overview:

Mensuration is often based on making use of a model or base object that serves as the standard for making the calculations. Within a computer, information is represented and stored in a digital binary format. The term bit is an abbreviation of binary digit and represents the smallest piece of data. Humans interpret words and pictures; computers interpret only patterns of bits. A bit can have only two possible values, a one digit (1) or a zero digit (0). A bit can be used to represent the state of something that has two states. For example, a light switch can be either On or Off; in binary representation, these states would correspond to 1 and 0, respectivel

​DIGITAL REPRESENTATION

​Within a computer, information is represented and stored in a digital binary format. The term bit is an abbreviation of binary digit and represents the smallest piece of data. Humans interpret words and pictures; computers interpret only patterns of bits. A bit can have only two possible values, a one digit (1) or a zero digit (0). A bit can be used to represent the state of something that has two states. For example, a light switch can be either On or Off; in binary representation, these states would correspond to 1 and 0, respectively. Computers use binary codes to represent and interpret letters, numbers and special characters with bits.

​DIGITAL REPRESENTATION

​Capital letter: A = 01000001

Number: 9 = 00001001

Special character: # = 00100011

​

​Each group of eight bits, such as the representations of letters and numbers, is known as a byte. Codes can be used to represent almost any type of information digitally: computer data, graphics, photos, voice, video, and music.

​​CONVERT DECIMAL NUMBERS TO BINARY

To convert a decimal number to binary, all you have to do is divide the number by 2. Get the quotient and the remainder. Bring down the quotient, divide it by 2, and get the quotient and remainder again. Do it repeatedly until the quotient results to 0. Copy the remainder from bottom to top, and that is the binary equivalent.

CALCULATING DATA STORAGE

While a bit is the smallest representation of data, the most basic unit of digital storage is the byte. A byte is 8 bits and is the smallest unit of measure (UOM) used to represent data storage capacity. When referring to storage space, we use the terms bytes(B), kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB).

CALCULATING DATA STORAGE

One kilobyte is a little more than one thousand bytes, specifically 1,024. A megabyte represents more than a million bytes or 1,048,576. A gigabyte is 1,073,741,824 bytes. A terabyte is 1,099,511,627,776. The exact number is gained by taking 2^n power. Once we know the size of a file or folder, it is possible to determine the number of bytes being us
