Study Notes
Multiprogramming vs Multiprocessing
- Multiprogramming allows multiple unrelated programs to run concurrently by sharing CPU time, ensuring no interference.
- Although programs appear to run concurrently, they actually take turns using the CPU.
- Time-sharing enhances multiprogramming by enabling many users to interact with a single computer simultaneously.
- Multiprocessing involves multiple CPUs linked together for parallel processing, enabling simultaneous execution of several programs.
- Multiprogramming is based on one CPU, while multiprocessing utilizes multiple CPUs for faster processing.
Programming Languages
- Programming languages are systems of symbols and characters enabling communication between humans and computers.
- Coding, the process of writing instructions for computers, can range from machine language to natural language-like syntax.
- Machine Language is the fundamental language for computers, consisting of binary codes (1's and 0's) directly executable without translation.
- Assembly Language is low-level language using mnemonic codes for operations, making it easier to remember and type.
Key Programming Concepts
- Cut-off Procedures: Ensure transactions are processed in the correct accounting period.
- File Controls: Procedures to confirm correct data files are engaged in online processing.
- Master File Controls: Manage changes to master files similarly to input controls.
- Balancing: Establish control totals for data processing to maintain accuracy and completeness.
- Rejected Data: Procedures ensuring completeness of rejected items before reprocessing.
Centralized vs Decentralized Processing
- Centralized Processing: All data processing occurs at a single mainframe computer location, allowing for organization-wide operations.
- Decentralized Processing: Involves multiple localized computers handling data independently, offering quicker access to information for users.
Distributed Processing
- Distributed Processing utilizes multiple computers to run applications, often across Local Area Networks (LANs).
- It involves a system where a single program can execute simultaneously across different sites.
Computer Output Terms
- Fields, databases, files, and records are terms used to describe data organization in computing.
- For example, inventory data on-screen includes part numbers, descriptions, and quantities, forming a record.
Automation and Data Entry
- Common automation devices in banks include Magnetic Ink Character Recognition (MICR) for processing paper documents.
- Online real-time systems and batch processing can coexist within firms, adapting to operational needs.
Software Types and Characteristics
- Compilers convert source language statements into object programs while checking for syntax errors.
- Shareware refers to software available on a trial basis, allowing users to test before purchasing.
- Magnetic disks are often used for data storage, employing concepts such as record keys, indexes, and pointers for efficient data retrieval.
Frequently Asked Questions
- The computational power of a microprocessor is indicated by the number of bits processed per second.
- Uninterruptible Power Supplies (UPS) help prevent data loss in computer centers.
- Electronic Funds Transfer (EFT) enhances auditing trails for international cash transactions, promoting efficiency and reducing errors.
