Which handheld device combines computing, telephony, and internet features into one?

• Tablet
• Smartphone
• Palmtop
• Mainframe

Answer explanation

Smartphones integrate PC and mobile features along with connectivity.

Palmtops are less popular today mainly because:

• They are too large
• They lack compressed keyboards
• Smartphones and tablets replaced them
• They consume too much power

Answer explanation

Palmtops were replaced by smartphones/tablets with better features.

Which of these tasks is LEAST suited for a handheld device?

• Browsing the web
• Playing simple games
• Running complex weather simulations
• Making calls

Answer explanation

Weather simulations need supercomputers, not handhelds.

Game consoles differ from general-purpose computers because they:

• Cannot display graphics
• Are designed specifically for gaming
• Use interpreters instead of compilers
• Lack storage capacity

Answer explanation

Consoles are gaming-specialized machines.

Which statement is TRUE about embedded systems?

• They cannot function without internet
• They are always portable
• They are dedicated to specific tasks
• They can replace mainframes

Answer explanation

Embedded systems are task-specific controllers inside larger devices.

In a washing machine, the embedded system mainly:

• Controls the spin speed and wash cycle
• Provides gaming features
• Connects to internet for updates
• Processes millions of instructions per second

Answer explanation

Washing machines use embedded systems to regulate operation.

Compared to microcomputers, minicomputers:

• Support fewer users
• Are more expensive and powerful
• Are always portable
• Have lower processing speeds

Answer explanation

Minicomputers are costlier but more powerful, supporting many users.

Which of these is a correct feature of minicomputers?

• Can only be used by one person
• Typically used in banks and universities
• Measured in FLOPS
• Smaller than handheld devices

Answer explanation

Minicomputers are popular in organisations like banks/universities.

Mainframes are primarily different from supercomputers because they:

• Focus on transaction processing and data handling
• Are smaller in physical size
• Are cheaper and slower
• Handle scientific calculations faster

Answer explanation

Mainframes focus on bulk transactions, supercomputers on scientific tasks.

Which is the most accurate statement about performance measures?

• Mainframes use FLOPS, supercomputers use MIPS
• Minicomputers use FLOPS, supercomputers use MIPS
• Supercomputers use FLOPS, mainframes use MIPS
• Microcomputers use MIPS, embedded systems use FLOPS

Answer explanation

Supercomputers are measured in FLOPS, mainframes in MIPS.
