(a) What are the two parts of an IP address called? ANS--The two parts of an IP address are called the network ID and the host ID also called Prefix and Suffix. (b) Normally, what is the last step in the boot-up process? ANS--The Last Step Of Boot Process is to Load The Operating System and Give all the control to The OS. (c) What is a hub? ANS--Hub is a Networking Device , this is use as a central point of connection in media segments this is a network connector. (d) Find the netid and hostid of the following IP addresses.
IP Address NetID HostID 132.7.21.84 132.7.21. 192.8.56.2 192.8.56.. ANS-- (e) What can detect whether central processing unit hardware problems exist? ANS-- Central processing unit hardware problems can be detected by monitoring its temperature and usage, using diagnostic tools, listening for unusual noises, checking for BIOS errors.
Part-B : Long Questions Q. (a) What is BIOS actually doing when the computer is initially turned or powered on? When a computer is initially turned on , the BIOS (Basic Input/Output System) performs a series of crucial tasks to prepare the system for the operating system to take over. Here's a simplified overview that what BIOS actually doing when the computer is initially turned :
1. Power-On Self Test (POST): The BIOS conducts a thorough hardware check, verifying the integrity of essential components like the CPU, RAM, motherboard, and peripheral devices. This ensures that the system's hardware is functioning properly before proceeding further. 2. Initialization and Configuration: The BIOS initializes and configures various system settings, including memory timings, clock speed, and input/output device configurations. These settings are crucial for optimal system performance and compatibility. 3. Boot Device Identification: The BIOS scans for boot able devices connected to the system, such as hard drives, solid-state drives, or USB devices. It identifies the boot device specified in the BIOS settings and prepares to load the operating system from that device. 4. Boot Loader Execution: The BIOS loads the boot loader, a small program residing on the boot device. The boot loader's responsibility is to locate and launch the operating system kernel, the core component of the operating system. 5. Handoff to Operating System: Once the operating system kernel is loaded into memory, the BIOS hands off control to the operating system. The operating system then takes over the initialization of system services, device drivers, and user interface elements.
