3. Which of the following types of memory is the fastest from the CPU’s point of view?

A) RAM

B) Cache

C) Hard Disk

D) Virtual Memory

Correct Answer:-

B) Cache - Cache is the fastest memory accessible directly by the CPU

Explanation:-

Cache: This is a very small and extremely fast type of memory located closest to the CPU. It stores data that the CPU frequently needs.

When the CPU looks for any data, it first checks the cache. If the data is found there (this is called a "cache hit"), the CPU can access it very quickly, which significantly improves system performance. Cache is hundreds of times faster than RAM.

Shortcut Trick:-

> "Close to CPU = Faster access"

Cache < RAM < Hard Disk (in speed)

Cache > RAM > Hard Disk (in cost)

4. Which of the following women is credited with writing the world’s first computer algorithm?

A) Grace Hopper 

B) Ada Lovelace 

C) Joan Clarke 

D) Hedy Lamarr 

Correct Answer:-

B) Ada Lovelace

Explanation:-

Ada Lovelace (1815–1852) is known as the "First Programmer."

She wrote an algorithm for the Analytical Engine, designed by Charles Babbage.

This laid the foundation for the coding we use today.

At that time, computers hadn't even been properly developed, but she conceptualized the algorithm in advance.

The Ada Programming Language is named after her and is used in the defense and aviation industries.

5. Which is the first programming language?

A) Python

B) C

C) FORTRAN (FORmula TRANslation)

D) Java

Correct Answer:- C) FORTRAN

The first high-level programming language was FORTRAN (FORmula TRANslation). It was developed in 1957 by a team at IBM led by John Backus.

6. Binary systemలో ఉపయోగించే సంఖ్యలు ఏవి?

A) 1 – 100 వరకు

B) 0 & 1 మాత్రమే

C) 1 – 10 వరకు

D) 0 – 9 వరకు

Correct Answer:- B) 0 & 1 మాత్రమే

కంప్యూటర్ భాషలో రెండు అంకెలే 0 & 1 ఇవే మొత్తం డిజిటల్ ప్రపంచానికి బేస్

7. The first electronic digital computer, ENIAC (Electronic Numerical Integrator and Computer), weighed about 30 tons. It was completed in 1945. ENIAC was so large that it filled an entire room.

Weight:- Approximately 30 tons (or 60,000 pounds).

Size:- It occupied about 1,800 square feet of space.

Components:- Around 18,000 vacuum tubes, along with thousands of resistors, capacitors, and switches.

8. Which company developed the first computer mouse?

a) Microsoft

b) Xerox

c) IBM

d) Apple

Correct Answer:- b) Xerox

9.Which data structure is used for implementing recursion?

A) Queue

B) Linked List

C) Stack

D) Tree

Correct Answer:- C) Stack

Explanation:-

Recursion works by storing each function call until it completes. These calls are stored in the call stack, a special kind of stack data structure.

Every time a function calls itself:-

It gets pushed onto the stack.

When it finishes, it gets popped off.

This LIFO (Last In, First Out) behavior is exactly how a stack works.

Quick Tip for Learners:-

If you've ever hit a "stack overflow error", it's because recursion went too deep and the stack ran out of space.
