The effects of using
ICT
Negative aspects in using ICT :
1. Software copyright theft
*
Software being copied and sold or given to others.
* Using the name
of copyrighted software if you are not permitted to do this.
* Using software
on a network of more users that you have paid
* Software being
copied and then amended and passing it off as your own.
2. Computer viruses
A program that
replicates itself automatically and can cause harm by copying files, deleting
files or corrupting files.
Preventing a virus attack
1. Install anti-virus software.
2. Not open file attachment to emails unless you know who they are
from.
3. Not allow anyone to attach portable drives or memory sticks to
your computer unless
they are scanned for viruses first.
4. Not download games and the other software from a site on the
Internet unless a trusted site.
3. Hacking and hackers
Hacking is the
process of accessing a computer system without permission.
Hackers often
access a computer system using the Internet.
Protecting
against hackers :
1.Use
a firewall (hardware or software) :
* To prevent
hackers accessing a computer or network
using the Internet.
* To prevent
undesirable content being accessed by users using the Internet.
2. Protecting access by using user-IDs and passwords
* Identifying
the user to the system : user-IDs
* Preventing
unauthorized access to the system: the use of passwords.
* Encryption
* Advice about
passwords.
Effects of ICT on Employment
a. Fewer people needed to completed the same amount of work
b. Increased number of people working from home (called telecommuting or
teleworking)
c. More automation in factories due to the introduction of robots for welding, paint spraying,
and packing goods.
d. Continual need for training as ICT systems change.
e. More availability of part-time work as many organizations need to be staffed 24/7.
f. More variation in the tasks
undertaken and staff need to be
flexible and well trained
to cope with
this.
g. Fewer “real” meetings as “virtual” meetings using videoconferencing are used to
reduce travel time and travel costs.
h. Increase in the number of technical staff needed such as network managers.
Areas of works where there is increased unemployment
1. Many
manual repetitive jobs
2. Online store.
3. Call center work.
4.
Designing and producing Cds/DVDs.
Areas of work where ICT has increased employment
· Networks
manager/administrator
· Web
site designers
· Development

The Effect of microprocessor - controlled devices in the home
Computer
systems contain one or more
microprocessor for the main processing
and this called the CPU.
a. Washing machines
b. Children's toys
c. Heating systems
d. Alarm systems
e. Digital cameras
f. Intelligent ovens and microwave
g. Intelligent fridges
The Effect of microprocessor- controlled devices on leisure time

and rely on machines.
4. Lack of fitness as
people are not spending time doing
manual work
5. Can use the extra time saved go to the gym or exercise more.
