Identify the most appropriate option. A computer must have:
Processor
Understanding Essential Computer Components
The question asks to identify the component that a computer must have to function as a basic computing device. Let's examine each option to understand its role.
Analyzing Computer Components
- Processor (CPU - Central Processing Unit): This is often called the "brain" of the computer. The processor performs all the calculations, executes instructions, and manages the flow of data. Without a processor, a computer cannot process information or run programs. It is absolutely essential for any device to be classified as a computer.
- Printer: A printer is an output device used to produce hard copies of documents or images. While useful, a computer can function perfectly well without a printer. It is an optional peripheral device.
- Gaming Consoles: Gaming consoles are specialized computer systems designed primarily for playing video games. While they contain processors and other computer components, the term "Gaming consoles" refers to the entire specialized system, not a single component that every computer must have. Standard computers are not necessarily gaming consoles, and gaming consoles themselves rely on essential components like a processor.
- CD/DVD Player: A CD/DVD player is a drive used to read data from or write data to optical discs. Many modern computers, especially laptops, no longer come equipped with built-in CD/DVD players as data storage and distribution methods have evolved (e.g., USB drives, cloud storage, digital downloads). A computer can function without a CD/DVD player. It is an optional input/output or storage device.
Identifying the Most Essential Component
Based on the analysis, the processor is the core component required for a computer to perform its fundamental tasks of processing information and executing instructions. The other options are peripheral devices or specific types of systems that are not universally necessary for a computer's basic operation.
Conclusion on Essential Computer Hardware
A computer requires several basic components to operate, including memory (RAM), storage (like a hard drive or SSD), input/output mechanisms, and a motherboard to connect them. However, the central processing unit (CPU), or processor, is the indispensable component that performs the actual computation. Without a processor, a computer cannot execute any task or run any software.
Revision Table: Computer Component Roles
| Component | Role | Essential for Basic Function? |
|---|---|---|
| Processor (CPU) | Executes instructions, performs calculations | Yes |
| Printer | Prints documents (Output) | No |
| Gaming Console | Specialized system for gaming | No (It's a type of system, not a component every computer needs) |
| CD/DVD Player | Reads/Writes optical discs (Storage/I/O) | No |
Additional Information on Computer Architecture
Beyond the processor, a basic computer system typically includes:
- Motherboard: The main circuit board connecting all components.
- Memory (RAM - Random Access Memory): Stores data and instructions currently being used by the processor for quick access.
- Storage (Hard Drive, SSD): Stores data and programs permanently.
- Power Supply Unit (PSU): Provides power to all components.
- Input Devices: Like a keyboard and mouse (though minimal systems can exist without them for specific tasks).
- Output Devices: Like a monitor (essential for user interaction, but a server might run headless).
While many components work together, the processor is the central piece that enables computation itself.
Important Questions from Critical Reasoning
In this question, a passage is given followed by a statement. Read the passage carefully and judge the statement based on the given passage.
Over three lakh birds of different species have arrived in Kashmir valley, according to wildlife warden wetlands of Kashmir, Rouf Zargar. Usually every year, approximately 9 lakh birds migrate to the valley from different cold habitats of the world. Therefore, the valley witnesses new species of birds every year. Birds can go any place depending upon the leading flock. Kashmir is comparatively less cold than their own natural habitat which makes birds to start migrating to the valley in September every year.
The birds can help in increasing tourism in the valley. Shikara owner Bashir Ahmad said, "Since tourism in valley is not gaining its pace in valley after 2016 turmoil, these migratory birds can attract tourist from across the globe, if tourism department can project them in planned way, and advertise at big level, definitely it will help to boost tourism in valley"
Statement:
Birds migrate to Kashmir valley as it is colder compared to their natural habitat.
Choose the appropriate one from the following options
A -The statement is definitely true
B -The statement is probably true
C -The statement is cannot be determined
D -The statement is definitely false
- Statement:
The cross cultural social work implies the interaction between one culture and a client of another culture.
Conclusion:
It enables the professional social work for effective intervention of cross cultural diversity management. - Among the following propositions two are related in such a way that one is the denial of the other. Which are those propositions?
