Explanation

An integrated circuit is a small chip of semiconductor material, typically silicon, that contains numerous tiny MOSFETs.

The five generations of computers:

1. First Generation (1946-1959 or 1940-1956): Vacuum tube-based technology (e.g., ENIAC).
2. Second Generation (1959-1965 or 1956-1963): Transistor-based technology.
3. Third Generation (1965-1971 or 1964-1971): Integrated circuit-based technology.
4. Fourth Generation (1972-1980): VLSI microprocessor-based technology.
5. Fifth Generation (1980-present): ULSI microprocessor-based technology, with a focus on artificial intelligence.

Explanation

EEPROM Stand for Electrically erasable programmable read-only memory.

EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge.

EEPROM is similar to Flash Memory

Explanation

POST

• Full Form: Power-On-Self-Test.
• Purpose: A set of routines run by BIOS to check hardware functionality during startup.
• Outcome: Generates beep sounds for successful tests; sounds vary by hardware.
• Bootstrap: Enabled after successful POST to load the operating system.

Explanation

Read-only memory  is a type of non-volatile memory

used in computers and other electronic devices.

Explanation

Three types of bus are used.

Address bus: carries memory addresses from the processor to other components such as primary storage and input/output devices. 

Data bus : carries the data between the processor and other components.

Control bus: carries control signals from the processor to other components.

Explanation

کمپیوٹر ایک برقیاتی آلہ جو حساب کے سوال اور پیچیدہ شماریاتی مسئلے، مقررہ اور پروگرامی ہدایات کے مطابق ،آسانی سے حل کر لیتا ہے.

Explanation

Keyboard is not software.

It is a hardware input device.

It is used to interact with a computer.

Explanation

• A microcontroller at least consists of a processor as its CPU with RAM, ROM, I/O ports and timers.
• It may contain some additional peripherals like ADC, PWM, etc.

Explanation

Explanation

An output device is any device used to send data from a computer to another device or user.
