database the executives, introductions, games, and that's only the tip of the
iceberg.
It was the math procedure of Abacus which was originated in Egypt and
popularized in China that prompted the improvement of computers. In 1642,
the Pascaline, a mechanical calculating device was invented by the French
philosopher and mathematician Blaise Pascal. It has eight movable dials on
wheels that could perform only addition and subtraction. While math device is
an old ascertaining device, computers are present day devices, which performs
numerous capacities. The PCs have become an integral part of individuals. Math
device can likewise be called as the most seasoned PC.
Regardless of whether you understand it or not, PCs assume a significant
job in our lives. At the point when you pull back money from an ATM, examine
staple goods at the store, or utilize an adding machine, you're utilizing a kind of
PC.
Charles Babbage is considered to be the father of computer while Lady
Ada is the first computer programmer. Computer are divided into 5 generations
namely:
First Generation: Vacuum Tubes (1940-1956)
Initially discovered by Thomas Edison, the vacuum tube formed the
building block for the entire electronics industry. Vacuum tubes were later used
as electron valves in the 20th century to build the first electronic computers.
The primary PC frameworks utilized vacuum tubes for hardware and
attractive drums for memory, and were frequently gigantic, occupying whole
spaces. These PCs were over the top expensive to work and notwithstanding
utilizing a lot of power, the primary PCs created a great deal of warmth, which
was regularly the reason for breakdowns.
Original PCs depended on machine language, the least level programming
language comprehended by PCs, to perform tasks, and they could just take care
of each issue in turn. It would take administrators days or even a long time to
set-up another issue. Info depended on punched cards and paper tape, and
yield was shown on printouts. Punched cards were used by the French weaver
Joseph Jacquard in 1810. The cards carried weaving instructions for the looms,
later this idea offered a great use for storing information.
Second Generation: Transistors (1956-1963)
The world would see transistors supplant vacuum tubes in the second era
of PCs. The transistor was imagined at Bell Labs in 1947 yet didn't see broad
use in PCs until the late 1950s.
3

The transistor was far better than the vacuum tube, permitting PCs to
decrease, quicker, less expensive, more vitality productive and more solid than
their original ancestors. In spite of the fact that the transistor despite everything
created a lot of warmth that exposed the PC to harm, it was a tremendous
improvement over the vacuum tube. Second-age PCs despite everything
depended on punched cards for information and printouts for yield.
Third Generation: Integrated Circuits (1964-1971)
The advancement of the coordinated circuit was the sign of the third era
of PCs. Transistors were scaled down and put on silicon chips, called
semiconductors, which definitely sped up and productivity of PCs.
Rather than punched cards and printouts, clients communicated with
third era PCs through consoles and screens and interfaced with a working
framework, which permitted the gadget to run a wide range of utilizations one
after another with a focal program that observed the memory. PCs just because
got open to a mass crowd since they were littler and less expensive than their
antecedents.
Fourth Generation: Microprocessors/Microchips (1971-Present)
The microprocessor brought the fourth era of PCs, as a large number of
coordinated circuits were constructed onto a solitary silicon chip. What in the
original occupied a whole room could now fit in the palm of the hand. The Intel
4004 chip, created in 1971, found all the parts of the PC—from the focal
preparing unit and memory to enter/yield controls—on a solitary chip.
Fifth Generation: Artificial Intelligence (Present and Beyond)
Fifth era figuring gadgets, in view of artificial intelligence, are still being
developed, however there are a few applications, for example, voice
acknowledgment, that are being utilized today. The utilization of equal handling
and superconductors is assisting with making man-made reasoning a reality.
COMPUTER PROGRAMMING
Computer programming is the process of designing and building an
executable computer program for accomplishing and building an executable
computer program for accomplishing a specific computing task. Programming
involves tasks such as: analysis, generating algorithms, profiling algorithms’
accuracy and resource consumption, and the implementation of algorithms in
a chosen programming language (commonly referred to as coding). The source
code of a program is written in one or more languages that are intelligible to
programmers, rather than machine code, which is directly executed by the
central processing unit. The purpose of programming is to find a sequence of
instructions that will automate the performance of a task (which can be as
complex as an operating system) on a computer, often for solving a given
problem. The process of programming thus often requires expertise in several
4

different subjects, including knowledge of the application domain, specialized
algorithms, and formal logic.
TYPES OF COMPUTER PROGRAMMING
1. Machine and Assembly Languages - is a low-level programming
language. It is a group of languages. It implements a symbolic
representation of the machine code.
2. Algorithmic Languages – are used to design mathematical or symbolic
computations. It is used to express algebraic operations. This is the first
high-level language.
3. Business-Oriented Languages - is a high-level programming language
that is used for business applications. It is used to design the operating
system agnostic and in many business applications today.
4. Education-Oriented Languages - are some Education-oriented
languages like BASIC, Pascal, Logo etc.
5. Scripting Languages – is a scripting language can be defined as a
programming language is used for integrating and communicating with
other programming languages. JavaScript, VB Script, PHP, Perl are the
most used scripting language.
6. Document Formatting Languages - is used to specify the organization
of printed text and graphics. This mark-up describes the intended
function of portions of a document.
7. Declarative Languages - is a very high-level programming languages. It
is also known as the non-procedural programming language.
8. Object-Oriented Languages - is a computer programming language that
revolves around the concept of an object.
COMPUTER PROGRAMMER
A computer programmer creates the code for software applications and
operating systems. After a software developer designs a computer program, the
programmer writes code that converts that design into a set of instructions a
computer can follow. They test the program to look for errors and then rewrite
it until it is error-free. The programmer continues to evaluate programs that are
in use, making updates and adjustments as needed.

What is Computer Hardware?
Computer hardware is the physical components that a computer system
requires to function. It encompasses everything with a circuit board that
operates within a PC or laptop; including the motherboard, graphics card, CPU
(Central Processing Unit), ventilation fans, webcam, power supply, and so on.
14
What Is It

What is a Motherboard?
The motherboard is at the focal point of what
makes a PC work. It houses the CPU and is a
center that all other equipment goes through. The
motherboard goes about as a mind; designating
power where it's required, speaking with and
planning over every single other segment – making
it one of the most significant bits of equipment in
a PC. A motherboard contains the different components of computer.
15

What is a CPU (Central Processing/Processor Unit)?
The CPU (Central Processing Unit or processor) is
answerable for preparing all data from programs
run by your PC. The 'clock speed', or the speed at
which the processor forms data, is estimated in
gigahertz (GHz). This implies a processor
publicizing a high GHz rating will probably perform
quicker than a correspondingly determined
processor of a similar brand and age. It is the heart and brain of the computer.
What is RAM?
Random Access Memory, or RAM, is hardware found in
the memory openings of the motherboard. The job of
RAM is to briefly store on-the-fly data made by programs
and to do as such that makes this information promptly
open. The assignments that require irregular memory could be; rendering
pictures for visual communication, altered video or photos, performing various
tasks with numerous applications open (for instance, running a game on one
screen and visiting by means of Discord on the other).
16

What is a Hard Drive?
The hard drive is a capacity gadget answerable for putting away
lasting and impermanent information. This information comes
in a wide range of structures, however is basically anything
spared or introduced to a PC: for instance, PC programs, family
photographs, working framework, word-handling archives, etc.
What is a Graphics Processing Unit (GPU)?
Particularly significant for 3D rendering, the GPU does precisely what its name
proposes and forms enormous batches of realistic information. You will find
that your PC's illustrations card has at any rate one GPU. Instead of the
essential on-board realistic abilities that PC motherboards gracefully,
committed designs cards interface with the motherboard by means of a
development space to work only on realistic rendering. This likewise implies you
can overhaul your illustrations card in the event that you need to get more
execution from your PC.
What is a Power Supply Unit (PSU)?
A power supply unit, ordinarily condensed as PSU,
accomplishes something beyond flexibly your PC with
power. It is the point where force enters your
framework from an outside force source and is then
dispensed by the motherboard to singular part
equipment. Not all power supplies are made similarly
be that as it may, and without the correct wattage PSU, your framework will
neglect to work.

your computer.
A computer peripheral is a device that is connected to a computer but
is not part of the core computer architecture. The core elements of a computer
are the central processing unit, power supply, motherboard and the computer
case that contains those three components. Technically speaking, everything
else is considered a peripheral device. However, this is a somewhat narrow view,
since various other elements are required for a computer to actually function,
such as a hard drive and random-access memory (or RAM).
Most people use the term peripheral more loosely to refer to a device
external to the computer case. You connect the device to the computer to expand
the functionality of the system. For example, consider a printer. Once the printer
is connected to a computer, you can print out documents. Another way to look
at peripheral devices is that they are dependent on the computer system. For
example, most printers can't do much on their own, and they only become
functional when connected to a computer system.
Types of Peripheral Devices
There are many different peripheral devices, but they fall into three
general categories:
1. Input devices, such as a mouse and a keyboard
2. Output devices, such as a monitor and a printer
3. Storage devices, such as a hard drive or flash drive
Some devices fall into more than one category. Consider a CD-ROM drive;
you can use it to read data or music (input), and you can use it to write data to
a CD (output).
Peripheral devices can be external or internal. For example, a printer is
an external device that you connect using a cable, while an optical disc drive is
typically located inside the computer case. Internal peripheral devices are also
referred to as integrated peripherals. When most people refer to peripherals,
they typically mean external ones.
The concept of what exactly is 'peripheral' is therefore somewhat fluid.
For a desktop computer, a keyboard and a monitor are considered peripherals
- you can easily connect and disconnect them and replace them if needed. For
a laptop computer, these components are built into the computer system and
can't be easily removed.
The term 'peripheral' also does not mean it is not essential for the function
of the computer. Some devices, such as a printer, can be disconnected and the
computer will keep on working just fine. However, remove the monitor of a
desktop computer and it becomes pretty much useless.
1. INPUT DEVICE - device used for entering data or instructions to the
central processing unit
20

Classification of input devices according to the method they use to enter data.
A. KEYING DEVICES - devices used to enter data into the computer using
a set of Keys e.g. Keyboard, key-to- storage and keypad.
ex. keyboard
B. POINTING DEVICES - devices that enter data and instructions into the
computer using a pointer that appears on the screen. The items to be
entered are selected by either pointing to or clicking on them. e.g mice,
joystick, touch sensitive screen, trackballs
ex. mouse
C. SCANNING DEVICES - devices that capture an object or a document
directly from the source. They are classified according to the technology
used to capture data e.g. Scanners and Document readers.
ex. scanners, document readers, bar code readers, optical scanner
readers
2. OUTPUT DEVICE - any piece of computer hardware equipment which
converts information into human-readable form. It can
be text, graphics, tactile, audio, and video.
ex. Monitor, Printer, Graphic Output devices, Plotters, Speakers
3. STORAGE DEVICE - refers to a computing hardware used to store
information permanently or temporarily
The device can be external or internal to a computer, server, and other
computing systems. Storage devices are also known as storage medias or
storage medium.
Two types of storage device
1. secondary storage device - has a larger storage capacity and can store
data permanently
Ex. compact disk, USB flash drive, hard disk
2. primary storage device - quite smaller in size and it’s designed to
capture or hold data for a temporary period
Ex. Cache memory and RAM
Directions: In the Venn Diagram, classify the following devices
as output, input, or both (input or output).

In the previous lesson, you learn about the different peripheral
devices. In this lesson, you will learn the intangible part of a computer
and its classification.
What is Software?
• Software is a set of electronic instructions that tells the computer
how to do certain tasks. A set of instructions is often called a
program.
• When a computer is using a particular program, it is said to be
running or executing the program.
Computer software is the key to productive use of computers. Software can be
categorized into two types:
 System software
 Application software.
System software
It is a software that exists primarily for the computer itself, to help the
computer perform specific functions. One major type of system software is the
operating system (OS). All computers require an operating system. The OS tells
the computer how to interact with the user and its own devices. Operating
system software tells the computer how to perform the functions of loading,
storing and executing an application and how to transfer data. Today, many
computers use an operating system that has a graphical user interface (GUI)
that provides visual clues such as icon symbols to help the user. Microsoft
Windows 10 is a widely used graphical operating system. DOS (Disk Operating
System) is an older but still widely used operating system that is text-based.
Ex. Windows, the Macintosh OS, OS/2, and UNIX .
Application Software
Application software consists of programs that tell a computer how to
produce information. It tells the computer how to accomplish tasks the user
requires, such as creating a document or editing a graphic image. Some of the
more commonly used packages are:
24
What Is It
What’s In

• Word processing programs Spreadsheet software
• Database management Presentation graphics programs
• Graphics programs Networking software
• Web design tools and browsers Internet applications
• Communications programs Utilities
• Entertainment and education Multimedia authoring
Word Processing
 Word Processing software is used to create and print documents. A key
advantage of word processing software is that users easily can make
changes in documents.
Electronic Spreadsheet
 Electronic spreadsheet software allows the user to add, subtract, and
perform user-defined calculations on rows and columns of numbers.
These numbers can be changed and the spreadsheet quickly recalculates
the new results.
25

Database Software
 Allows the user to enter, retrieve, and update data in an organized and efficient
manner, with flexible inquiry and reporting capabilities.
Presentation Graphics
 Presentation graphic software allows the user to create documents called slides
