2nd Quarter CSS Week 1
Computer memory
What is computer memory?
• Computer Memory is any physical device capable of storing
information temporarily, like RAM (Random Access Memory), or
permanently, like ROM (Read-Only Memory). Memory devices utilize
integrated circuits and are used by operating systems, software, and
hardware.
Computer Memory
• There are two types of computer memory. Volatile memory (RAM)
and Non-volatile memory (ROM). Computer memory is based on the
two factors that include access time and capacity. The faster the
speed of the memory, the lesser will be the access time.
access time = How fast can the date be transferred
Capacity = How large or how many data can it store temporarily of
permanently.
Volatile memory (RAM)
The main memory unit that connects directly to the CPU is the primary
memory. Furthermore, there are two types of primary memory:
RAM and ROM
RAM
RAM is a volatile memory which means its data will be erased if there is
no power or electricity.
It is measured by its access time and capacity.
MHz or Megahertz
• This is the unit of measurement to which we measure the speed of
data being transferred in one clock cycle.
Unit of measurement of data
8 Bits - 1 Byte
Bytes (1024) - KiloByte (1KB)
KB (1024) - MegaByte (1MB)
MB (1024) - GigaByte (1GB)
GB (1024) - TeraByte (1TB)
TB (1024) - PetaByte (1PB)
PB (1024) - ExaByte (1EB)
EB (1024) - ZettaByte (1ZB)
ZB (1024) - YottaByte (1YB)
1024 YB - BrontoByte
1024 BrontoByte - 1 GeopByte
In computer memory, bits are the smallest memory. While Geopbyte is the highest memory. 1 bit is the binary
unit.

The ones and zeros above could be just numbers for you but in binary
code the numbers mean “Hello!”.
Did you know that computers don’t understand words or numbers the
way humans do? All computer data is represented using binary, a
number system that uses 0s and 1s. Binary digits can be grouped
together into bytes
Binary
Computers use binary - the digits 0 and 1 to store data. The smallest unit of
data in computing is called a binary digit, or bit. It is presented by a 0 or 1.
The tiny switch is called a transistor which is activated by the electronic
signals it receives. The circuits in a computer's processor are made up of
billions of transistors. The digits 1 and 0 used in binary reflect on and off
states of a transistor.
Some of your computer files such as software, music, documents, and any
other information that is processed by a computer is also stored using
binary.
Binary
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 Interchange (ASCII).
With ASCII, each character is represented by a string of bits.
For Example:
Capital letter: F = 01000110
Number: 1 = 00110001

Recall
1. What is binary?
• Computers use binary - the digits 0 and 1 to store data. The smallest unit of
data in computing is called a binary digit, or bit. It is presented by a 0 or 1.
2. How do computers read binary?
• With the use of transistors that turns on and off. It uses the binary as a signal
when it should turn on and off. 0 is off 1 is on.

Bits and Bytes
• Bits can be grouped together to make them easier to work with. A
group of 8 bits is called a byte. 8 bits (b) is equivalent to 1 byte (B)
1 or 0 = 1 bit
01010010 = 8 bit or 1 Byte
Remember
• Most computers can process millions of bits every second. A hard drive's
storage capacity is measured in gigabytes or terabytes. RAM is often
measured in megabytes or gigabytes.
• A number base indicates how many digits are available within a numerical
system. The binary system on computers uses combinations of 0s and 1s.
That why it is called Binary
• In everyday life, we use numbers based on combinations of the digits
between 0 and 9. For binary numbers there are only two possible digits
available: 0 or 1. The binary system is also known as base 2. Denary or base
10 in counting system is known as decimal. Denary is known as base 10
because there are ten choices of digits between 0 and 9. That’s why it is
called Denary
Conversion from Decimal to Binary
• 1. Compute the quotient and the remainder.
• 2. Bring down the quotient, divide it by 2, and get the quotient and
remainder again.
• 3. Do it repeatedly until the quotient results to 0.
• 4. Copy the remainder from bottom to top and that is the binary
equivalent.
Check your understanding
• Convert these decimals into binary.
1. 177
2. 232
3. 99
4. 76
5. 88
Conversion from Binary to Decimal
• Conversion can be done by plotting each binary digit value on each
column corresponding to its decimal digit value. Each column is the
number 2 raised to an exponent. The exponent increases by one from
right to left. To get the total value you add the value of those columns
tagged as ON or equivalent to 1.

Storage device and storage capacity
• Before deciding what kind or type of storage device you need to use,
it is important to identify the requirements or specification of your
data storage. When deciding on the type of device needed, you
should consider cost, capacity, speed of access, portability,
durability, and reliability.

Hard drive Magnetic 1TB
Memory card Flash 64GB
REMEMBER
• The most common unit of digital data storage is a bit. It is also called
as binary and it is considered as the standard unit in which a
computer stores data.
• To increase the size of information stored, bits are clustered into
groups of eight, which equals to a byte. This measurement process
continues exponentially (1 bit = 8 bytes, 1 kilobyte = 1,024 bytes,
etc.).
1 byte = 8 bits
The table below shows the unit measurement system which helps users
understand the storage process of computers. Here is a basic table to
illustrate how the units increase exponentially.
8 bits
As you can see, the conversions vary from a standard system such as the
metric system. 1 kilobyte does not convert to 1,000 but instead 1,024
bytes. The process simplifies and allows quick calculations due to the
pattern of growth (1024KB to 1024MB to 1024GB etc.).
8 bits
Calculating Storage Capacity
• Have you ever thought of how many files can be stored in a storage
media? Here are the steps on how to calculate how many files can be
stored in a storage media.
To calculate how much data can be stored within a certain capacity you
need to understand three things:
1. The size of the data being stored.
2. The available space (capacity) for storing the data.
3. How to convert between the relevant units?
Remember
• Most files in our computer contain thousands of bytes and file sizes
are often measured in kilobytes.
• Larger files, such as images, videos, and audio files, contain millions of
bytes and are measured in megabytes.
• Modern storage devices can store thousands of these files, that is
why storage capacity is typically measured in gigabytes or even
terabytes.
• Being familiar on the process and how the digital unit conversion
measurements helps you understand sizes of storage devices.

Remember
• Technical Drawing is an act or discipline of creating models or plans
to build something through designs. It includes blueprints,
schematics, and diagrams that communicate how to construct a
product, device, machine, highway, or home. They also include
sketches and 2D and 3D-models that represent the appearance of a
completed project.
• Technical drawings are used widely throughout many industries by
professionals including architects, engineers, CAD Technicians,
product designers, and mathematicians.
Types of technical drawing
A. Schematic diagram
B. Charts
C. Block diagram
D. Lay-out plans/Floor plan
Schematic diagram
• A schematic is defined as a picture that
shows something in a simple way, using
symbols. A schematic diagram is a
picture that represents the components
of a process, device, or other object
using abstract, often standardized
symbols and lines.
• Schematic diagrams are widely used in
electrical drawing. The main purpose of a
schematic diagram is to emphasize
circuit elements and how their functions
relate to each other.
Charts
• In general, a chart is a graphical
representation of data.
• Charts allow users to see what the results
of data to better understand and predict
current and future data.
Block diagrams
• A block diagram is a visual
representation of how
parts of an object relate to
each other and work
together. It is named as
such because blocks
represent each piece of the
design with lines between
them to show their
respective relationships.
Lay-out Plans
• A floor plan is a scaled diagram of a
room or building viewed from above.
• The floor plan may depict an entire
building, one floor of a building, or a
single room. It may also include
measurements, furniture, appliances,
or anything else necessary to the
purpose of the plan.

Computer memory
Primary and secondary memory of a computer
What is memory?
• To us Humans Memory is the faculty of the mind by which data or
information is encoded, stored, and retrieved when needed.
• To a computer memory is a device or system that is used to store
information for immediate use in a computer or related computer
hardware and digital electronic devices.
What are the different types of memory in a
computer.
Primary memory Secondary Memory
Primary memory is the internal memory
of a computer system. It stores and
retrieves data, instructions, and
information. The CPU directly and
randomly accesses primary memory;
hence primary memory is also referred
to as Random Access Memory or RAM. It
is a volatile memory and loses data and
instructions when the power turns off.
Secondary memory is a storage
device that cannot be accessed
directly by the CPU. It is used as a
permanent storage device.
The CPU accesses these devices
through an input/output channel,
and data is first transferred to
primary memory from secondary
memory before being accessed.
What are the difference between primary and secondary memory?
Comparison
parameters Primary Memory Secondary Memory
Storage Validity Primary memory is the main memory and
stores data temporarily.
Secondary memory is the external
memory and stores data permanently.
Access
The CPU can directly access the data.
The CPU cannot directly access the
data.
Volatility
Primary memory is volatile. It loses data in
case of a power outage.
Secondary memory is non-volatile, and
data is stored even during a power
failure.
Storage
Data is stored inside costly semiconductor
chips.
Data is stored on external hardware
devices like hard drives, floppy disks,
etc.
Speed Faster Slower
Stored data It saves the data that the computer is
currently using.
It can save various types of data in
various formats and huge sizes.
What are memory devices and where do they
belong? Primary or secondary?
Direct comparison between primary and
secondary.

D. List the steps, activities, and decisions to be charted.
How will interpreting flow chart help?
Flowchart will help you understand your process and uncover
ways to improve if you use it to analyze what is happening.
Interpreting your Flowchart will help you to:
• determine who is involved in the process.
• form theories about root causes.
• identify ways to streamline the process.
• determine how to implement changes to the process.
• locate cost-added-only steps.
• provide training on how the process works or should work.
Below is a Sequence of Steps That Will Help You
Through an Orderly Analysis of Your Flowchart
• Step 1 - examine each process step of the following conditions that indicate
a need to improve the process.
• Step 2 - examine each decision symbol. You may want to collect data on
how often there is a "yes" or "no" answer at decision points marked by a
diamond shaped symbol. If most decisions go one way rather than the
other, you may be able to remove this decision point.
• Step 3 - examine each rework loop. Processes with numerous checks
generate rework and waste. Examine the activities preceding the rework
loop and identify those that need to be improved. Look for ways to shorten
or eliminate the loop.
• Step 4 - examine each activity symbol. Does the step help build a key
quality characteristic into the end product? If not, consider eliminating it.
POST-TEST

    What is computermemory? • Computer Memory is any physical device capable of storing information temporarily, like RAM (Random Access Memory), or permanently, like ROM (Read-Only Memory). Memory devices utilize integrated circuits and are used by operating systems, software, and hardware.
  • 3.
    Computer Memory • Thereare two types of computer memory. Volatile memory (RAM) and Non-volatile memory (ROM). Computer memory is based on the two factors that include access time and capacity. The faster the speed of the memory, the lesser will be the access time. access time = How fast can the date be transferred Capacity = How large or how many data can it store temporarily of permanently.
  • 4.
    Volatile memory (RAM) Themain memory unit that connects directly to the CPU is the primary memory. Furthermore, there are two types of primary memory: RAM and ROM
  • 5.
    RAM RAM is avolatile memory which means its data will be erased if there is no power or electricity. It is measured by its access time and capacity.
  • 6.
    MHz or Megahertz •This is the unit of measurement to which we measure the speed of data being transferred in one clock cycle.

Did you know that computers don’t understand words or numbers the way humans do? All computer data is represented using binary, a number system that uses 0s and 1s. Binary digits can be grouped together into bytes
  • 10.
    Binary Computers use binary- the digits 0 and 1 to store data. The smallest unit of data in computing is called a binary digit, or bit. It is presented by a 0 or 1. The tiny switch is called a transistor which is activated by the electronic signals it receives. The circuits in a computer's processor are made up of billions of transistors. The digits 1 and 0 used in binary reflect on and off states of a transistor. Some of your computer files such as software, music, documents, and any other information that is processed by a computer is also stored using binary.
  • 11.
    Binary Computers use binarycodes to represent and interpret letters, numbers, and special characters with bits. A commonly used code is the American Standard Code for Information Interchange (ASCII). With ASCII, each character is represented by a string of bits. For Example: Capital letter: F = 01000110 Number: 1 = 00110001

    Bits and Bytes •Bits can be grouped together to make them easier to work with. A group of 8 bits is called a byte. 8 bits (b) is equivalent to 1 byte (B) 1 or 0 = 1 bit 01010010 = 8 bit or 1 Byte
  • 18.
    Remember • Most computerscan process millions of bits every second. A hard drive's storage capacity is measured in gigabytes or terabytes. RAM is often measured in megabytes or gigabytes. • A number base indicates how many digits are available within a numerical system. The binary system on computers uses combinations of 0s and 1s. That why it is called Binary • In everyday life, we use numbers based on combinations of the digits between 0 and 9. For binary numbers there are only two possible digits available: 0 or 1. The binary system is also known as base 2. Denary or base 10 in counting system is known as decimal. Denary is known as base 10 because there are ten choices of digits between 0 and 9. That’s why it is called Denary
  • 19.
    Conversion from Decimalto Binary • 1. Compute the quotient and the remainder. • 2. Bring down the quotient, divide it by 2, and get the quotient and remainder again. • 3. Do it repeatedly until the quotient results to 0. • 4. Copy the remainder from bottom to top and that is the binary equivalent.

    Storage device andstorage capacity • Before deciding what kind or type of storage device you need to use, it is important to identify the requirements or specification of your data storage. When deciding on the type of device needed, you should consider cost, capacity, speed of access, portability, durability, and reliability.

    REMEMBER • The mostcommon unit of digital data storage is a bit. It is also called as binary and it is considered as the standard unit in which a computer stores data. • To increase the size of information stored, bits are clustered into groups of eight, which equals to a byte. This measurement process continues exponentially (1 bit = 8 bytes, 1 kilobyte = 1,024 bytes, etc.). 1 byte = 8 bits
  • 36.
    The table belowshows the unit measurement system which helps users understand the storage process of computers. Here is a basic table to illustrate how the units increase exponentially. 8 bits
  • 37.
    As you cansee, the conversions vary from a standard system such as the metric system. 1 kilobyte does not convert to 1,000 but instead 1,024 bytes. The process simplifies and allows quick calculations due to the pattern of growth (1024KB to 1024MB to 1024GB etc.). 8 bits
  • 38.
    Calculating Storage Capacity •Have you ever thought of how many files can be stored in a storage media? Here are the steps on how to calculate how many files can be stored in a storage media. To calculate how much data can be stored within a certain capacity you need to understand three things: 1. The size of the data being stored. 2. The available space (capacity) for storing the data. 3. How to convert between the relevant units?
  • 41.
    Remember • Most filesin our computer contain thousands of bytes and file sizes are often measured in kilobytes. • Larger files, such as images, videos, and audio files, contain millions of bytes and are measured in megabytes. • Modern storage devices can store thousands of these files, that is why storage capacity is typically measured in gigabytes or even terabytes. • Being familiar on the process and how the digital unit conversion measurements helps you understand sizes of storage devices.
  • 42.
    Short review • Situation1 Task: Identify how many file you can fit in the storage device. Problem: Jose wants to copy games from his friends PC. Each game has an average size of 900MB and Jose only have a hard drive that is 1TB in capacity.

    Computer memory Primary andsecondary memory of a computer
  • 115.
    What is memory? •To us Humans Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed. • To a computer memory is a device or system that is used to store information for immediate use in a computer or related computer hardware and digital electronic devices.
  • 116.
    What are thedifferent types of memory in a computer. Primary memory Secondary Memory Primary memory is the internal memory of a computer system. It stores and retrieves data, instructions, and information. The CPU directly and randomly accesses primary memory; hence primary memory is also referred to as Random Access Memory or RAM. It is a volatile memory and loses data and instructions when the power turns off. Secondary memory is a storage device that cannot be accessed directly by the CPU. It is used as a permanent storage device. The CPU accesses these devices through an input/output channel, and data is first transferred to primary memory from secondary memory before being accessed.
  • 117.
    What are thedifference between primary and secondary memory? Comparison parameters Primary Memory Secondary Memory Storage Validity Primary memory is the main memory and stores data temporarily. Secondary memory is the external memory and stores data permanently. Access The CPU can directly access the data. The CPU cannot directly access the data. Volatility Primary memory is volatile. It loses data in case of a power outage. Secondary memory is non-volatile, and data is stored even during a power failure. Storage Data is stored inside costly semiconductor chips. Data is stored on external hardware devices like hard drives, floppy disks, etc. Speed Faster Slower Stored data It saves the data that the computer is currently using. It can save various types of data in various formats and huge sizes.

    Steps in makinga linear flowchart 1. Define the process to be flowcharted. The purpose for flowcharting it. 2. Assemble the right people to develop the flowchart. Those operators, technicians, or office workers who are involved in the process. 3. Establish process boundaries. The starting and ending points. • identify the major activities or sub processes that are included in the process. • determine what is not included in the scope of the process to remove any doubt or confusion about the boundaries. This may also help establish the scope of related processes.
  • 139.
    Steps in makinga linear flowchart 4. List the steps, activities, and decisions to be charted. If your team is not sure about a step, mark it to be investigated later. 5. Put the steps in chronological sequence. Sometimes it is easier to start with the last step and work back to the first step. 6. Assign flowchart symbols such as boxes, diamonds, and triangles. 7. Review and title the flowchart.

    How will interpretingflow chart help? Flowchart will help you understand your process and uncover ways to improve if you use it to analyze what is happening. Interpreting your Flowchart will help you to: • determine who is involved in the process. • form theories about root causes. • identify ways to streamline the process. • determine how to implement changes to the process. • locate cost-added-only steps. • provide training on how the process works or should work.
  • 146.
    Below is aSequence of Steps That Will Help You Through an Orderly Analysis of Your Flowchart • Step 1 - examine each process step of the following conditions that indicate a need to improve the process. • Step 2 - examine each decision symbol. You may want to collect data on how often there is a "yes" or "no" answer at decision points marked by a diamond shaped symbol. If most decisions go one way rather than the other, you may be able to remove this decision point. • Step 3 - examine each rework loop. Processes with numerous checks generate rework and waste. Examine the activities preceding the rework loop and identify those that need to be improved. Look for ways to shorten or eliminate the loop. • Step 4 - examine each activity symbol. Does the step help build a key quality characteristic into the end product? If not, consider eliminating it.

Editor's Notes

  • #139 #1: Kaylangan nyong I define yung gagawin nyo. Alamin nyo kung bakit kayo gagawa ng flow chart. #2: Etong step na to ay kaylangan nyong I consider kung mag sasama kayo or may involved na ibang tao sa gagawin nyong process #3: Dito sa step 3 kaylangan ma identify nyo yung mga Major activities at sub processes dahil pag nalaman nyo na ang mga major activities at sub processes ma lalaman nyo na kung ano anong mga bagay ang kasama lang sa scope ng flow chart nyo. Pwede kayo mang alis or tangal ng activity na hindi naman kaylangan sa flow chart.
  • #140 #4: After nyong ma identify yung mga Major activities at sub processes pwede nyo nang I lista ngayong yung mga process or steps na I le layout nyo para sa mga Major activities and sub processes na yon. Kung sakali lang na hindi kayo sure sa isang step na nilagay nyo sa flow chart pwede nyong markahan at mag investigate kayo kung yun ba ay kaylangan or kaylangan nyong baguhin. #5: So sa step 4 na list nyo na lahat ng steps sa flowchart nyo ngayon syempre pag gumagawa tayo ng flowchart dapat tama ang flow nya, chronological ibigsabihin sunod sunod base sa pangyayari. And ang isang tip sa inyo na pwede nyong I try pag gumagawa ng flowchart, pwede nyong subukan na gawin ang flow chart from the last step pabalik sa first step. #6: Pagtapos nyong I arrange ang mga steps in chronological order (Step 5) mag a assign na kayo ngayon ng symbol. Syempre kaylangan nyong I identify kung anong symbol ang step na yon. #7: sa step na ito, tapos na ang flow chart nyo. Kaylangan nyong reviewhin ang flow chart nyo para ma check kung may mali ba or may pwedeng I improve and them saka no to bibigyan ng title.
  • #147 Step 1: I check yung mga process kung yun ba ay kaylangan ng improvement Ex: Baka hindi malinaw ang process, baka kaylangan mag dagdag or mag bawas ng process. Step 2: Dito kaylangan natin tignan kung gaano karami yung decision points natin. Kung ang isang decision point ay madalas naman na iisa lang ang sagot either yes or no palagi, baka pwedeng alisin na at gawin na lang itong process. Step 3: Yung rework loop makikita to sa decision points. Kung masyadong marami ang rework loop pwedeng makapag cause yun ng delay or pag haba ng process or waste. I check nyo at kung pwedeng I eliminate yung rework loop mas OK. Etong step 4 ay directly connected sa 3 dahil ang tinutukoy neto ay yung mga decision points. Step 4: I check natin yung mga symbol kung yun po ba ay makaka tulong para makapag produce tayo ng quality end product. Pwedeng mag dagdag kung kulang or hindi malinaw ang flow chart or pwedeng mag bawas kung masyadong mahaba ang flow, or pwedeng may baguhin kung kayang mas ma improve and flow.
