Understanding Evaluation of System Resources
System resources refer to the hardware and software components that enable a computer to function.
NoteSystem resources are finite and must be managed efficiently to ensure optimal performance.
Types of Computer Systems
Different computer systems have varying resource requirements based on their intended use. Let's explore some common types:
Mainframes
Mainframes
Powerful computers designed for large-scale data processing and critical applications.
They are characterised by:
- High processing power: Capable of handling millions of transactions per second.
- Vast memory: Equipped with terabytes of RAM to support multiple concurrent users.
- Robust storage: Utilise arrays of disks and backup tapes to ensure data integrity.
- Reliability: Designed for fault tolerance and continuous operation.
Mainframes are used in industries like banking, healthcare, and government for tasks such as transaction processing and data analysis.
Supercomputers
Supercomputers
Computers that are specialised for complex mathematical calculations and simulations.
Key features include:
- Massive parallelism: Utilise thousands of processors working simultaneously.
- High-performance computing: Measured in FLOPS (Floating Point Operations Per Second).
- Applications: Weather forecasting, molecular modelling, and scientific research.
Supercomputers prioritise raw computational power over multitasking capabilities.
Servers
Server
A device or program that provides services or resources to clients
Servers require:
- Multiple network connections: For handling high volumes of data traffic.
- Ample RAM: To support simultaneous requests from multiple clients.
- Fault tolerance: Redundant components to ensure uptime.
- Security: Advanced measures to protect data and services.
Common server types include web servers, database servers, and file servers.
Personal Computers (PCs)
PCs are designed for individual use and offer a balance of performance and affordability.
They typically include:
- Moderate processing power: Suitable for everyday tasks like web browsing and document editing.
- Expandable storage: HDDs or SSDs for data storage.
- Versatile operating systems: Windows, macOS, or Linux.
