Match the columns.

Match List-I with List-II

List – I (Computer Terms)	List – II (Purpose)
A. Motherboard	I. Stores the date, time and system configuration for BIOS
B. BIOS	II. Allows processor and other hardware to function and communicate with each other
C. CMOS	III. Transfer the contents of web pages into a web browsers for viewing
D. HTTP	IV. Initializes and tests the system hardware components and loads an OS when a computer is turned on

Choose the correct answer from the options given below:

Correct option is C

A. Motherboard → II. Allows processor and other hardware to function and communicate with each other
· The motherboard is the main circuit board of a computer.
· It connects the CPU, memory, storage, and peripherals, facilitating communication among them.
B. BIOS → IV. Initializes and tests the system hardware components and loads an OS when a computer is turned on
BIOS (Basic Input Output System) is firmware that initializes the hardware and loads the bootloader or operating system during startup.
C. CMOS → I. Stores the date, time, and system configuration for BIOS
· CMOS (Complementary Metal-Oxide Semiconductor) is a small battery-powered chip on the motherboard.
· It stores system settings like date, time, and hardware configuration, which are accessed by the BIOS.
D. HTTP → III. Transfer the contents of web pages into a web browser for viewing
HTTP (HyperText Transfer Protocol) is a protocol used for transferring hypertext (web page content) from web servers to browsers.
Information Booster
1. Motherboard:
o Acts as the central hub connecting all hardware components.
o Contains slots for CPU, RAM, storage devices, and peripheral connections.
2. BIOS (Basic Input Output System):
o Pre-installed firmware.
o Executes the POST (Power-On Self-Test) and loads the operating system.
3. CMOS:
o A chip powered by a small battery to store hardware configuration data.
o Keeps the system time and date even when the system is powered off.
4. HTTP (HyperText Transfer Protocol):
o Application layer protocol for communication over the web.
o Used for requesting and transferring web page content.
Additional Knowledge
· HTTP vs HTTPS: HTTPS (Secure HTTP) adds encryption (via SSL/TLS) to secure data transfers.
· BIOS vs UEFI: UEFI is the modern replacement for BIOS, offering faster boot times and better hardware support.
· CMOS Battery: If the CMOS battery fails, the system may lose date, time, and BIOS settings.
