The document discusses the key elements of a computer system including people, procedures, software, and hardware. It notes that people operate and use the computer system. Procedures are documented guidelines and rules. There are two types of software: system software which runs the computer and application software which performs specific tasks. Hardware is the physical equipment like the central processing unit, memory, storage, input/output devices, and communication devices. It needs software to function properly.

2. 1. PEOPLE
• Important part of the Information
System Technology
• Who operate, input data and use the
resulting information

3. 2. PROCEDURE
• Set of guidelines and rules
• Documented in Manuals:
–Software and hardware
manufacturers

4. 3. SOFTWARE
• Instructions that tell the computer
how it should do its work
• Process the data (raw facts) into
usable information

5. 3. SOFTWARE
• Two kinds:
1. System software

6. 3. SOFTWARE
• Two kinds:
1. Application software

7. 4. HARDWARE
• Physical equipment that implements
the data processing
• Physical parts or components of a
computer
• Needs software for it to run
smoothly and d0 its specified task

8. 4. HARDWARE
• Input/Output units
• input- convert data
and instruction into
electronic form
• Output- convert
electronic data
produced and
display them

9. 4. HARDWARE
• Memory unit/Storage devices
–Where the programs and data are
stored
–Random Access Memory (RAM)

10. 4. HARDWARE
• Memory unit/Storage devices
–Where the programs and data are
stored
–Read Only Memory (ROM)

11. 4. HARDWARE
• Central Processing Unit (CPU)
–Operations of data and information
are controlled and where programs
are executed

12. 4. HARDWARE
• Communication devices
–Components that connect the
computer to the internet and other
external devices

13. 5. DATA
• Include text, numbers, sounds,
images and video
• Facts and facet of records

14. 6. CONNECTIVITY
• Allow the computer to access and
share data and information
• Usually means internet connection

HARDWARE

17. HARDWARE
• Physical equipment which includes
the input and output devices and
Central Processing Unit

18. HARDWARE
• CPU/Microprocessor is the brain of the computer
• Motherboard:
– CPU fan, Memory card or RAM etc.
– Power supply
– Case fan, power cable and SATA cable
– LAN card

– Optical Drive or CD/DVD-ROM drive
– Ports and Wire

19. HARDWARE
• Storage devices are used to store data
• May either be internally installed in the
CPU case or Removable
–Hard drive
–Compact Disk Read Only Memory or
CD ROM
–Digital Versatile Disk (DVD)
–Flash Drive

20. HARDWARE
• Computer memory that stores data are:
–RAM which is the main memory
–ROM- a memory on which data have
been prerecorded
–Preserves its content even when the
computer is turned off
–Ex. System Startup
