 TYPES OF COMPONENTS AND OBJECTS TO BE MEASURED

1. Memory - is the internal storage areas in the computer system. The term memory
identifies data storage that comes in the form of chips,
and the word storage is used for memory that exists on
tapes or disks. It could be internal or external.

2. Data storage capacity - refers to how much disk space one or more storage devices
provides. It measures how much data a computer system may contain. For an
example, a computer with a 500GB hard drive has a storage capacity of
500 gigabytes. A network server with four 1TB drives, has a storage
capacity of 4 terabytes.

3. Processor - is an integrated electronic circuit that performs the calculations that run a
computer. A processor performs arithmetical, logical,
input/output (I/O) and other basic instructions that are passed
from an operating system (OS).

4. Video card - is used to process images so they can be displayed on your monitor. A
good video card can make a big difference in the quality of
your graphics, so this is particularly important if you play
games or work with photography and video.

 Measurements can be Categorized into Two:

A. COMMON UNITS OF MEASUREMENT

A unit of measurement is the quantity used as a standard to express a physical

quantity. The following are the basic quantities being measured and the respective units
used:

Some of the common units are as follows:

• millimeter (mm) – a metric unit commonly used to express the length of very small
objects like keys, and thickness of small objects like notebook.

• centimeter (cm) – a metric unit commonly used to express the length of small objects.
It is also used in measuring the height of a person.

• inch (in) – an English unit commonly used to express the length of small objects such
as boxes and bottles.

• foot (ft) – an English unit equivalent to 12 inches. It is commonly used to express short
distances, and height of all objects like trees and buildings.

B. DIGITAL STORAGE UNITS OF MEASUREMENT

Nowadays, digital storage units are the common ways computer data is expressed.
They are typically connected using bytes and usually abbreviated in expression. The table
below shows the basic digital storage units, their symbols and its equivalents.

Unit of Measurement Symbol Equivalent

1 bit b 0 or 1
1 Byte B 8 bits
1 Kilobyte KB 1024 Bytes
1 Megabyte MB 1024 Kilobytes
1 Gigabyte GB 1024 Megabytes
1 Terabyte TB 1024 Gigabytes
1 Petabyte PB 1024 Terabytes
1 Exabyte EB 1024 Petabytes
1 Zettabyte ZB 1024 Exabytes
1 Yottabyte YB 1024 Zettabytes

MEASURING INSTRUMENTS

Measuring instruments and gauges are used to measure various parameters such as
clearance, diameter, depth, ovality, trueness, etc.

Name of Instrument and Description Picture

CALCULATOR
An electronic calculator is typically a
portable electronic device used to perform
calculations, ranging from basic arithmetic
to complex mathematics.

OHMMETER
An ohmmeter is an electrical instrument
that measures electrical resistance (the
opposition offered by a substance to the
flow of electric current)

MULTIMETER
Also known as a VOM (volt-ohm-
milliammeter), is an electronic measuring
instrument that combines several
measurement functions in one unit. A
typical multimeter can measure voltage,
current, and resistance.
AMMETER
An ammeter (from ampere meter) is a
measuring instrument used to measure the
current in a circuit. Electric currents are
measured in amperes (A).

DIGITAL REPRESENTATION

Binary patterns do not only represent numerical values, they may represent other types
of data as well such as alphabetical characters. The ability to
encode non-numerical data in digital form is what allows
computers to manipulate and communicate text.

The beauty of binary representation is that the individual

“bits” are easy to encode in physical form. “1” and “0” values may take the form of voltage
levels (“high” or “low”) in an electronic circuit. Computers use binary codes to represent and
interpret letters, numbers, and special characters with bits. A commonly used code is the
American Standard Code for Information.
9
 Example:
Capital Letter M = 0100 1101
Small letter p = 0111 0000
Number 8 = 0011 1000
Special Character: 0011 1111

CONVERT DECIMAL NUMBERS TO BINARY

In converting a decimal number to binary, you must divide the number by 2. Get the
quotient and the remainder. Bring down the quotient, divide it by 2, and get again the quotient
and remainder. Do it repeatedly until the quotient results to 0. Copy the remainder from
bottom to top to get the binary equivalent.

10
 Example: 25

Quotient Remainder

25/2 12 1

12/2 6 0

6/2 3 0

3/2 1 1

1/2 0 1

25 = 11001

Checking: 1 1 0 0 1 multiplier

16 8 4 2 1 equivalents

16 8 0 0 1 results
16+8+1 = 25

CALCULATING DATA STORAGE

Bit is the smallest representation of data and byte is the most basic unit of digital storage.
A byte is 8 bits and is the smallest unit of measure (UOM) used to represent data storage
capacity.
The terms bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes
(TB) are used in addressing the memory capacity of a file or document. 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

Data in computers are stored and transmitted as a series of ones and zeros. To store
an image on a computer, the image is broken down into tiny elements called pixels. A pixel
(short for picture element) represents one color. An image with a resolution of 1024 by 798
pixels has 817,152 pixels.

Kilobytes, megabytes, gigabytes, and terabytes are typically used to measure the size
or storage capacity of a device. Examples of components and devices that use byte storage
include Random Access Memory (RAM), hard disk drive space, CDs, DVDs, and MP3 players.

A single-sided, single-layer DVD can hold 4.7 GB of data, more than 6 CDs. Single-
sided, dual-layer DVDs have a storage capacity of 8.5 GB and double-sided, dual-layer DVDs
have a capacity of 17 GB. Approximately 3 hours of standard definition video can be stored on
a DVD.

A file is 30 KB in size
1 KB = 1,024 Bytes
30 * 1,024 = 30,720 bytes in a 30 KB file

If a 30 KB file is stored in a 1 MB folder (1 MB = 1,048,576 bytes of space); then

approximately a total of 34 files can be stored in that folder (1,048,576 / 30,720 =34.1).

12
Let’s do some exercises

1. If a flash drive has 16 Gigabytes capacity, how much does it represent in Megabytes?
Remember: 1 Gigabyte = 1000 Megabyte

Solution: 16 GB x 1024 𝑀𝐵 = 16384 MB

1 𝐺𝐵

2. In a hard drive that has 2 terabytes capacity, what is its equivalent value in gigabytes?

Solution: 2 TB x 1024 𝐺𝐵 = 2048 GB

1 𝑇𝐵
