the correct answer is ​GigaHertz.

Key Points

• Clock speed:
  • Clock speed is the significant way to measure the performance of Processor.
  • ​CPU processes many instructions (low-level calculations like arithmetic) from different programs every second. The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz).
  • A “cycle” is technically a pulse synchronized by an internal oscillator, but for our purposes, they’re a basic unit that helps understand a CPU’s speed.
  • During each cycle, billions of transistors within the processor open and close.
  • A CPU with a clock speed of 3.2 GHz executes 3.2 billion cycles per second.

The correct answer is Control Unit and ALU.

• Computers have become pervasive in every walk of life.
• It has changed the way we work, play, communicate and learn.
• A computer essentially comprises of a set of hardware and software.

Key Points

The Central Processing Unit (CPU):

• The CPU is the brain of the computer.
• Sometimes referred to simply as the processor or central processor, the CPU is where most calculations take place.
• The CPU executes the programs and controls the operation of all the hardware.
• The three main components of the CPU are:

The Control Unit (CU):

• It is one of the most important parts of the microprocessor as it is in charge of the entire process.
• The control unit extracts instructions from memory and decodes them.
• Based on these instructions, it creates control signals that tell the Arithmetic Logic Unit (ALU) and the Registers how to operate, what to operate on and what to do with the result.
• The role of the control unit in the CPU is that of a “manager”.
• In other words, it controls and coordinates all hardware operations.

The Arithmetic and Logic Unit (ALU):

• It is the section where the actual data processing takes place.
• All calculations and comparisons take place in this section.
• In addition to arithmetic functions, the ALU also handles logic operations.
• All mathematical operations are performed in binary numbers and all logic operations are performed using binary operations.

The Primary Memory (Main memory):

• This unit stores programs during their execution, stores data that are being used by the current program and stores the operating system which controls the operation of the computer system.
• It consists of Random Access Memory (RAM) where the user's programs and data must be stored in order to be run and Read-Only Memory (ROM) where permanent programs and data are built-in by the manufacturer.

Hence, it is clear that the Control Unit and ALU are the two main components of the CPU.

• BUS: It is a Data Communication System in a computer network. The ALU and CU that are linked internally and externally by busses which carry binary signals between.

• Register: They can be thought of as the CPU’s tiny scratchpad, temporarily storing instructions or data.

The correct answer is Random Access.

Key Points

• Random Access:
  • ​In computer science, random access is the capability to have access to any item from a given population of elements at random.
  • Random access is the opposite of sequential access, as sequential access locates elements by beginning at a particular predefined location and then traversing through all of the information in order to find the given item.
  • Random access has gained interest due to the fact that one can retrieve a record irrespective of the position in which it is located.
  • Random access is also known as direct access.

Compilers:

• A compiler is a program that translates a source program written in some high-level programming language into machine code for some computer architecture.
• The generated machine code can be later executed many times against different data each time.
• It writes the text into a format that the CPU can understand
• This is a kind of system software

Touch screen monitors:

• This is a device that helps the user to interact with the computer using their finger
• It is an alternative to mouse and keyboard for navigating a Graphical User Interface (GUI)
• It allows tough sensitive inputs as well as outputs.

Therefore it is clear that Compilers are software and Touch screen monitors are input/output devices. So both the statements are true.

An operating system is a software program that manages and operates computing devices.

Key Points

•  Mac OS is a powerful operating system that offers similar features and services to Windows and Linux. 
• The Macintosh Operating System (Mac OS) is an operating system developed by Apple Inc.
• It is a graphical user interface-based operating system that was first published in 1984.
• Apple is an American-based company located in California. 
• Mac OS is meant to run on Apple computers and does not support the x86 architecture by default.

Additional Information

• Microsoft Windows, usually known as Windows or Windows OS, is a personal computer operating system developed by Microsoft Corporation.
• Linux is a collection of open-source Unix-like operating systems based on Linus Torvalds' Linux kernel which was launched on September 17, 1991.
• Oracle Solaris is also an operating system. 

Hence,  the incorrect pair is .ttf - word text file.

A number system includes the number of independent digits used in the number system (the base), the place values of the different digits constituting the number, and the maximum numbers that can be written with the given number of digits.

The Binary Number System: 

• The binary number system with only two independent digits, 0 and 1, is a base-2 number system.
• All larger binary numbers are represented in terms of ‘0’ and ‘1’.

Decimal to Binary Conversion:

Step 1: Divide 22 by 2 to get the Quotient. Keep the Whole part for the next step and set the Remainder aside.

25 / 2 = 12 with 1 remainder

Step 2: Divide the Whole part of the Quotient from Step 1 by 2. Again, keep the Whole part and set the Remainder aside.

12 / 2 = 6 with 0 remainder

Step 3: Repeat Step 2 above until the Whole part is 0.

6 / 2 = 3 with 0 remainder

3 / 2 = 1 with 1 remainder

1 / 2 = 0 with 1 remainder

Step 4: Write down the Remainders in reverse order to get the answer to 25 as a binary.

When we put the remainder together in reverse order, we get the answer 11001

Hence, the binary equivalent of decimal number 25 is 11001

The correct answer is Read-Only Memory (ROM)

Key Points

• ROM stands for Read-Only Memory.
• ROM is a storage device that is used with computers and other electronic devices.
• Data stored in ROM may only be read.
