IT601 Midterm Subjective Preparation by MS Team

Different components of a system have objectives?

The components of an IT system and their objectives include:

� Computing Machines → Provide processing power (Servers, Workstations). � Software → Enable functionality (Operating Systems, Applications). � Network → Facilitates communication (Routers, Switches). � Services → Offer functionalities (Web, DNS, DHCP). � Users → Interact with the system. � Processes → Maintain operations (System updates, backups).

MTTF and MTTR Stand For?

� MTTF (Mean Time to Failure) → Average time before a system fails. � MTTR (Mean Time to Recovery) → Average time to fix and restore a failed system.

5 levels mai sy koi b level ho skta ha?

This refers to SAMM (System Administration Maturity Model) levels:

1. Initial (Ad-hoc processes) → No formal process.
2. Repeatable (Disciplined process) → Basic documentation.
3. Defined (Standard, Consistent process) → Well-documented procedures.
4. Managed (Predictable process) → Measured and controlled processes.
5. Optimizing (Continuously improving) → Ongoing refinement and automation.

CPU ki performance kaisi hai?

CPU performance depends on:

� Clock Speed (GHz) → Higher GHz means faster processing. � Number of Cores → Multi-core CPUs handle tasks efficiently. � Cache Size → L1, L2, L3 cache improves processing speed. � Instruction Set → Advanced architectures (e.g., x86, ARM) optimize performance.

Question tha k Windows ki operations bataen?

Windows Operating System performs various operations, including:

� File Management → Organizes files and folders. � Process Management → Manages running applications and background processes. � Memory Management → Allocates RAM to active programs. � User Management → Creates and manages user accounts. � Networking → Provides network connectivity through TCP/IP. � Security Management → Includes firewalls, encryption, and user permissions.

Ik level wla aya tha, yh jo next info ha yh table mai given thi or new users and software install sy btana tha k kon sa point kis heading sy related ha?

� This relates to SAMM levels and common system administration tasks:

Summary

1. New → Freshly unpacked system.
2. Clean → OS installed, but not configured.
3. Configured → Ready for use, properly set up.
4. Unknown → Misconfigured, outdated, or compromised state.
5. Off → Shut down or removed from the system.

States wala bhi question tha ik?

This refers to Evard’s Computer Machine Life Cycle which includes:

Buy in bulk allocate fraction waly ki advantages thi?

Advantages of buying in bulk and allocating fractions:

� Cost Efficiency → Discounts on large purchases. � Resource Optimization → Allocate only what is needed, reducing waste. � Scalability → Easily expand IT resources as needed. � Better Planning → Reduces frequent purchases and administrative overhead.
