tasks.
SECTION C
Question 1.
a) Draw a block diagram to illustrate the information processing cycle.
input process output
storage
* to get full marks, the arrangement of the whole diagram and arrows must be correct
completely.
b) L is an operating system
Function of L (Accept any one of the answer below)
i. Provides the users interface – Controls how the user enters the
data and instructions and how the information is displayed
ii. To manage data and program - when we start an application the
CPU loads the application from the storage to the memory.
Multitasking OS enables more than one application to run in the
same time.
iii. Managing memory such as optimizing the use of random access
memory (RAM), allocating data and instruction to area of
memory while being processed, monitoring the contents of
memory and releasing data and instructions from being
monitored in memory when the process is done.
iv. Handling input and output – enabling communications with input
and output devices.

Question 2.
a) Ahmad take action procedure scanning virus with Antivirus software. The
activities Ahmad does are :
If an antivirus program identifies an infected file, it attempts to remove its
virus, worm or Trojan horse.
 If the antivirus program cannot remove the infection, it often quarantines
the infected file.
 Quarantine is a separate area of a hard disk that holds the infected file until
the infection can be removed. This step ensures other files will not become
infected.
Ahmad mengambil langkah mengimbas virus dengan perisian AntivirusThe
activities Ahmad does are :
 Sekiranya program Antivirus mengenalpasti jangkitan pada fail, ia akan
menyimpan sementara sebelum memadam ia yang terdiri virus, worm atau
Trojan horse.
 Sekiranya antivirus tidak boleh membuang fail yang dijangkiti, ia akan
mengkuarantin fail tersebut.
 Kuarantin akan menyimpan fail yang dijangkiti pada ruang yang berasingan
di dalam cakera keras sehingga ia dipadam. Langkah ini memastikan
supaya fail lain tidak dijangkiti.
 Proses ini juga bergantung kepada fitur-fitur perisian antivirus yang diset
secara

b)
 File or confidential document already saved will be damage.
 Virus will destruction all the system computer.
 Computer software will be slow causes infected virus.
 Distraction emotion of computer user.
 Fail atau dokumen penting yang disimpan menjadi rosak. Kadangkala
fail atau dokumen yang dijangkiti virus tidak lagi boleh digunakan. Ada
sejenis virus yang boleh menukarkan fail .doc dan .xls menjadi fail .exe
maka fail ini tidak lagi boleh di buka. Fail yang rosak perlu ditaip semula.
Kadangkala maklumat di dalamnya penting dan tidak dapat dirujuk semula.
 Virus boleh menyebabkan kerosakan pada sistem komputer. Fail-fail
utama sistem pengendali yang dirosakkan oleh virus tidak lagi berfungsi
seperti biasa. Ini akan mengakibat sistem komputer rosak. Pengguna
terpaksa memasukkan sistem pengendali semula untuk membaikpulih
sistem komputer yang dijangkiti virus.
 Perjalanan perisian yang dijangkiti virus menjadi lambat. Oleh kerana
virus ini berada dalam ingatan komputer, maka ia akan menganggu
perjalanan perisian dan menyebabkan komputer memproses maklumat
menjadi terganggu dan lambat.
 Menganggu emosi pengguna komputer. Seseorang yang terlibat dengan
komputer yang dijangkiti virus boleh akan terganggu emosinya kerana fail-
fail yang penting hilang. Ianya memakan masa untuk menyiapkan semula
fail-fail yang telah rosak sedangkan fail-fail tersebut adalah sangat penting.
Question 3
1. MIS helps users to make decision / solve problems / supervise activities and
track the progress.
2. Phase X is Documentation.
- the collection and summarization of data and information
- includes reports, diagrams, programs or any other deliverables
generated during the system development cycle
- is an on-going part of the system development cycle
- is important as a reference for future development and maintenance
- as user manual
3. The interrelation between information systems components using a diagram.
