1 byte = 8 bits
= 21 bytes x 8
= 168 bits

Input, Output, Storage.
Input - Scanner, Mouse, Microphone, etc.
Output - Speaker, Printer, Projector, etc.
Storage - DVD, Thumbdrive, SSD, etc.
Briefly explain why UNICODE is widely used in our smartphone?
Latest smartphones involve the use of many languages which are not using English based alphabets that can only be represented using UNICODE
Identify most appropriate classification of network in the following situations :
Briefly explain one (1) advantage and one (1) disadvantage of using broadband Internet connection.
Advantage :
Provide connection speed up to 100 times faster than dial up connection, thus allowing the download huge amount of data within minutes
Phone line functions are not affected. Same phone line can be used for voice/fax and data transmission
Disadvantage :
Higher monthly access fee compared to dial-up connection
A personal firewall may be needed to protect your computer
May not be available in rural or remote areas
Identify two (2) examples of portable computers.
Notebook @ Laptop / Netbook/ Ultra-Thins
Tablet PCs
Palmtop (Hand held)
PDA (Personal Digital Assistant)
Wearable computer
Smart Phones
Explain what are the Input, Process, Output and Storage when Danial was given information “45 x 2 = 90” to be processed.
Input - Enter 45 and 2
Process - Multiplies 45 and 2 or 45 x 2
Output - Display 90 or Result 90
Storage - Store 90
Coding scheme X is widely use in most of mini computes and all personal computer, while coding scheme Y is widely used in several operating systems including Windows, Mac OS and Linux. Differentiate between coding scheme X and Y in terms of bit.
X - Using 8 bits coding which give a total of 256 types of character symbols
Y - Using 16-bits coding scheme which give a total of 65,536 types of character symbols
X is a type of network architecture. Some of the characteristics of X are - “Single password, administrator required, central point of failure “.
Name X and briefly explain it.
X - Client Server Architecture
Client server network is an architecture in which the user's PC (the client) is the requesting machine and the server is the supplying machine, both of which are connected via a network.
There are two versions of IP Address. The X is a protocol that uses a standard addressing scheme. However, Y has been developed since the mid-1990s in order to replace the X.
Name Y and briefly explain it.
Y is IPv6.
IPv6 address has three parts:
State two (2) the benefits of using solid state drive (SSD) compared to regular hard disk.
Less power usage than hard disk
Faster data access than hard disk
Transfer rate are faster than hard disk
Higher reliability
Siti needs pocket money and calls her father to bank in RM200 into her saving account. After her father had agreed and done the transaction, she went to the Bank Ceria Berhad to withdraw the money from the ATM machine. She received 4 pieces of RM50 notes.
Identify two (2) activities involved for process operations in the information processing cycle during the withdrawal process.
ATM machine verify ATM card
ATM machine verify PIN number
ATM machine determine transaction type
ATM machine determine account type
ATM machine determine amount to withdraw
ATM machine calculate balance
ATM machine determine the notes required
Name the logic symbols based on the description given below :
A gate which produces true output if either or both inputs are true. Otherwise, the output is false.
OR-Gate
Make a comparison for LAN and WAN in term of area covered, ownership and transmission speed.
Local Area Network
Connects computers and devices in a limited geographical area.
(building, school or home)
Owned or managed by a single person or organization
Have a higher data transfer rate compared to WAN
Wide Area Network
Connects computers and devices in a large geographical area. (country and world)
Not owned by any one organization
Have a lower data transfer rate as compared to LANs
Describe the relationship between Domain Name and IP Address.
IP address is a unique address used to locate and identify a device over a network. These all-numeric IP addresses are difficult to remember and use. Thus, the Internet supports the use of a text name that represents one or more IP addresses. A domain name is the text version of an IP address.
One of the types of secondary storage stores information on the surface of a circular disc and reads this information by illuminating the surface with a laser diode and observing the reflection. Identify that type of storage and give one (1) step can be used in taking care of that storage medium.
Type - Optical Disc (DVD, Blu-Ray Disc)
Step :
Do not expose the disc to excessive heat or sunlight
Do not stack disc
Do not eat, smoke or drink near a disc
Do store the disc in a box/case when not in use
