1. What is the computer? Differentiate between analog and digital Computers.
The computer is an electronic device that accepts data and instructions from the user, processes it, and gives meaningful information as output.
- It has the ability to store, retrieve and process data according to user requirements.
2. Explain the concept of RAM and cache memory. Write the types of cache memory.
RAM:
- RAM is the primary or main memory of the computer that stores data and instructions during the operation of the computer.
- RAM loses Information when the computer is powered off hence it is called the volatile memory.
Cache Memory:
- The fast memory placed between the CPU and RAM is known as cache memory.
- It acts as a buffer between the CPU and the main memory. It holds data and programs that are most frequently used by the CPU.
- When The CPU needs an instruction or data during processing, it first looks in the Cache.
Types of Cache Memory:
1. L1 Cache:
Extremely small and is located on the CPU itself. It is extremely fast but
has a small storage capacity. Also known as a primary cache. It is used to
store recently accessed information.
2. L2 Cache: L2 cache is much larger than L1 but at the same time slower as well.
It is located outside and separated from the CPU chip core, although
it is found on the same CPU chip package.
Faster than L3 but slower than L1.
3. L3 Cache: It is the slowest among all cache memory and has the largest size.
Also, all the cores in the CPU share the same L3 cache memory.
3. What is a control panel in the Windows operating system? List down the tasks that you can perform through the control panel.
The Control Panel is a central component of the Windows operating system that allows users to manage various system settings and configurations. Here are some of the tasks that can be performed through the Control Panel:
- System Settings: Adjust system settings, view information about your computer, and modify user accounts and security settings.

- Security and Maintenance: Manage security settings, run maintenance tasks, and view system status reports.
- Backup and Restore: Set up backup and restore settings for files, folders, and system images.
- Administrative Tools: Access advanced system settings and tools, such as Task Scheduler, Event Viewer, and Services.
These are just a few examples of the tasks that can be performed through the Control Panel in Windows. Depending on your version of Windows, the specific options and categories may vary.
