The document summarizes the experiences gained by a group of students during their industrial attachment at Cosmostech Learning Center in Yola, Adamawa State, Nigeria from October 2019 to March 2020. It discusses the various areas they specialized in including graphic design, computer hardware/software repairs and maintenance, networking and web development. It provides details on using tools in Adobe Photoshop, setting up documents, and the interface layout. It also covers topics like what is a computer, computer ports, system software, identifying computer problems, and the OSI model. The document is the group's report on their practical learning and includes their names and thanks to the school and training center.

2. APPRECIATION
We wish to appreciate the School
Management and the Department
for giving us the opportunity to
experience the practical aspect of
the lectures received in the school
here, and also appreciate the
management of COSMOTECH
Learning Center for accepting us as
we where by then.

3. EXPERIENCED GAIN
Graphic Design
Networking
Computer Hardware/Software
Repairs and maintenance
Web Development
Finally, we specialist on different
field based on our understanding

4. GRAPHIC DESIGN
Adobe Photoshop Graphic Design
Is a popular image editing software that
provides a work environment
consistent with Adobe in Design, Adobe
Photoshop and other products in the
Adobe Creative Suite. In this section
we learned how to use the interface
and how to modify images with basic

5. SETTING UP THE DOCUMENT
Setting up the document correctly from
the start will make your job much easier
as you work through your project. This
will require some advanced planning.
For example, if your final output will be a
brochure, you may need to set up your
document to be horizontal and double-
sided. As shown in the figure below.

7. INTERFACE LAYOUT

8. THINGS THAT PHOTOSHOP CAN HELP US DO
 Color box and mode (foreground and
background)
 Easy cropping with specific size
 Cropping with the marquee tool
 Resizing to specific size
 Enlarging
 Correction spots
 e.t.c
 TOOLS
 Clone stamp, shape, measuring and navigation,
slicing, moving, video editing, 3D extrusion,
camera raw, color replacement e.t.c.

9. WHAT IS COMPUTER?
 An electronic device, operating under the control
of instructions stored in its own memory that can:
– Accept data (as input)
– Process the data according to specified rules
(process)
– Produce results (as output)
– Store the results (storage) for future use.

11. COMPUTER SYSTEM FUNCTIONS ONLY

12. WHAT IS COMPUTER PORT?
Port:
 Is a connector on the motherboard or on a separate adapter that allows a
device to connect to a computer; these may include keyboard, mouse,
serial, parallel, network, sound, or video ports.
Ports vary with the type of equipment that connects to
the ports.
1. Male Ports: Have pins that protrude out from the connector and requires
a cable with a female connector.
2. Female Ports: Have holes in the connector to accept male cable’s pins.
D-shell connector: A connector with more pins or holes on the top
row than on the bottom so that a connected cable can only be
attached in one direction and not accidentally connected the wrong way;
generally represented with the letters DB and the number of pins such as,
DB-9, DB-15, or DB-25.
DIN connector: Round with small holes and normally keyed; the
keyboard and mouse are usually this type of connector with either 5 or 6
pins.

13.  The system software is collection of programs
designed to operate, control, and extend the
processing capabilities of the computer itself.
 System software are generally prepared by
computer manufactures.
 System software serves as the interface between
hardware and the end users. e.g. Operating
System, Compilers, Interpreter, Assemblers etc.

14. IDENTIFYING COMPUTER PROBLEMS/ISSUES
 Hardware or Software Problem?
 Note: Make sure you reduce possible “external”
problems before proceeding. This means unplug
any external devices (such as hard drives, scanners
or printers), and remove any USB Flash disk, CD or
DVD disks from their drives.
 Were there any loud noises or smoke when the
problem first appeared? Then it is probably a
hardware problem, with the most likely culprit being
the SMPS (Switched Mode Power Supply) unit.
 Is the computer entirely dead? Or the screen blank?
Or the screen showing a poor/incomplete picture?
These faults are probably also due to hardware
problems.

15. IDENTIFYING COMPUTER PROBLEMS/ISSUES
 Does the computer produce a series of beeps? This is a
code that can be used to distinguish some hardware
problems.
 Does the system give any error codes or descriptions
while booting? These can be due to hardware or software
problems. Take careful note of all information given in the
error code.
 Does the computer produce error information after it has
booted or only when you open specific programs? These
error codes are probably due to software problems.
 Have any recent changes been made to hardware or
software including BIOS settings? If so, these are likely
culprits.
 Has the computer been exposed to viruses or other
malware? This could be a cause of software problems.

16. CONCLUSION:
 Always ensure that the power has been turned off before
installing or troubleshooting any hardware part of the
computer.
 Before opening a computer case, always unplug the power
cord from your computer.
 Acer unplugging the power cord from your case, Hold the
power button in for at least 5 seconds. This will drain any
residual electricity from the power supply.
 Always ground yourself to the case frame while touching any
inside components.
 This can be done by touching the case frame with your bare
hand, or using a clamp-on grounding device made specifically
for this purpose.
 Keep all liquids away.
 Avoid installing components when the computer is in
operation.

17.  When installing any, peripheral or device, always read the
installation instructions that come with the device. Never apply
force to try and connect any plug/device.
 When fitting/handling processor on motherboard always wear
gloves.
 Always choose to shut down your computer by clicking
shutdown. Avoid switching of the power directly from the main
switch.
 If electrical power is lost, switch off all computer devices from
the mains to avoid any problems due to power surge.
 Always “eject “USB devices from the operating system before
disconnecting them.
 Upgrade the anti-virus regularly.
 Always use UPS (uninterruptible Power supply)-This will keep
your computer from crashing during power outages, and will
protect your computer from low and high voltage occurrences.

 Physical layer
(Defines the physical characteristics of the network)
 Data-link layer
(Provides saf communication of data over the physical
network)

(Manages sessions among applications)
 Presentation layer
(Provides standard data representations for
applications)
