LESSON 1
COMPUTER HARDWARE

SAINT CHARLES ACADEMY LESSON 1
It is the physical part of the computer that has
physical structure such as system unit, monitor,
mouse and keyboard. Like human brain, receives
data and instructions, stores them and processes
the data according to the instructions given to it
Hardware

It receives data from input devices, stores them in
memory and displays them through an output device.
The physical devices that make up a computer are
referred to as hardware.
Hardware

Computer hardware can be broadly classified into
two: CPU and peripherals. The CPU is perhaps the
most important part of a computer. The other hardware
pieces like input devices, output devices, etc. are
called peripherals.
Hardware

The CPU. It is a hardware within a computer that carries
out the instructions of a computer program by
performing the basic arithmetical, logical, and
input/output operations of the system. These is
known as the brain of the computer and one of the most
important chips in the computer.
Hardware

Hardware

Computers can be generally classified by size and
power, and group into categories in numerous ways. It
classifies the types of computers according to their physical
size, processing speed, cost, and number of users.
Types of Computer

Laptop or handheld computer, having a small size and low weight is easy to carry to anywhere
it is powered by battery or AC-powered personal computers that are more portable that desktop
computers, allowing the user to use anywhere. This is easy to carry around and preferred by
students and business people to meet their assignments and other necessary tasks.
Types of Computer

Desktop Computer, it is designed for use at desk or table and make up of separate components.
it has a monitor, keyboard, mouse, usually stays at one location. A workstation a powerful, single-
user computer is like a personal computer, but it has a more powerful microprocessor and, in
general, a higher-quality monitor.
Types of Computer

Server is a computer that "serves up" information to other computers on a network. A computer
that provides data to other computers. It may serve data to systems on a local area network or a
wide area network over the Internet
Types of Computer

A minicomputer is a multi-user computer capable of supporting up to hundreds of users
simultaneously. It might cost tens of thousands of dollars. It is about the size of a refrigerator and,
when combined with various peripherals, might fill a small room. Minicomputers often have
several hundred users.
Types of Computer

A mainframe computer is powerful multi-user computer capable of supporting many hundreds or
thousands of users simultaneously and it is housed in large rooms or even entire building floors.
They cost up to several million dollars, and thousands of users can access the computer
simultaneously. In a networked environment, minicomputers and mainframes are both frequently
called servers
Types of Computer

A supercomputer, the largest and most expensive computer, it is extremely fast computer that
can perform hundreds of millions of instructions per second and often used in research settings
and other environments that require a computer with extraordinary computing power. Some
supercomputers are capable of performing several billion instructions per second.
Types of Computer

How are data
stored?

Hard Drive - use to stores data, pictures, music and videos inside
the computer System.
Types of Storage
HDD - Hard Disk Drive
SSD - Solid State Drive

Flashdrive- known as a USB stick, USB thumb
drive or pen drive is a plug-and-play portable
storage device that uses flash memory and is
lightweight enough to attach to a keychain.
Memory Card- is an electronic data storage device
used for storing digital information, typically using
flash memory.
Types of Storage

DVD Disc - of optical disc technology that can stored
files ranging from 4.7 to 8 gigabyte. A Writable DVD
can hold more 1 GB of information
Diskette- Magnetic medium house in a rigid plastic
cartridge measuring 3.5 inches square that is a
random access, removable data storage medium
that can be used with personal computers.
Types of Storage

COMPUTER ASSEMBLY AND REPAIR TOOLS
For every job there is the right tool. Make sure that you are familiar
with the correct use of each tool and that the correct tool is used for the
current task. Skilled use of tools and software makes the job less difficult
and ensures that tasks are performed properly and safely.

MULTI-METER- a hand held electronic measuring
instrument use to measure the electrical voltage,
resistance and other values related to electricity
SCREWDRIVER- hand tools use for driving screws and
often rotating other machine elements with the mating
drive system

FLAT SCREW DRIVER – hand tool is used to drive
or fasten negative slotted screws.
TORX DRIVER- hand tool used to loosen or tighten
screws that have a star-like depression on the top, a
feature that is mainly found on laptop.

GLOVES- the covering material with a separate
sheath for each finger used for hand protection.
ANTISTATIC MAT- hand tool used to stand on or
place hardware on to prevent static electricity from
building up.

CRIMPING TOOL- Device used to conjoin two
pieces of metal by deforming one or both of them in
a way that causes them to hold each other
LAN TESTER- is a device designed to measure
and test existing LAN connection.

TWEEZERS- A tool use to hold small sensitive part of a
computer.
ANTISTATIC WRIST STRAP- antistatic device used to
safely ground a person working on very sensitive
electronic equipment, to prevent the buildup of static
electricity on their body, which can result in electrostatic
discharge.

SOLDERING IRON - tool used to join two or more
metal conductors with the support of soldering lead
melted around it.
DESOLDERING TOOL– is used to unsolder
unwanted parts or component in the circuit with the
support of soldering pencil.

PLIERS- hand tool used to hold objects firmly, for
bending, or physical compression.
LONG NOSE PLIERS – Used for holding, bending
and stretching the lead of electronics component or
connecting wire.

SIDE CUTTER PLIER- A tool used for cutting or
trimming of connecting wires or terminal leads in the
circuit board.
CUTTER- A tool used in stripping wires.

WIRE STRIPPER- is a portable handheld tool used
by workers, especially electricians, for removing the
protective coating of an electric wire in order to
replace or repair the wire.
