Computer Basics

Documentation in bank software development serves multiple purposes: correction (fixing bugs and updates), auditing (regulatory compliance and verification), and editing (ongoing maintenance). The term 'auditihg' appears to be a typo for 'auditing.' All three purposes are valid and essential in banking software where accuracy and compliance are critical.

Bluetooth security includes device authentication, which verifies the identity of connecting devices. While pairing and bonding are also part of Bluetooth security, device authentication is a core security provision that ensures only authorized devices can connect. The question correctly identifies this as a distinct security feature.

Smart cards are distinguished from magnetic stripe cards by their embedded microchip, which provides enhanced security and processing capabilities. Magnetic stripes, signatures, and photographs can all be found on traditional cards. The microchip is the unique element that enables smart cards to store and process data securely.

In an internet banking audit, physical verification of the server environment is important. 'Touring the server room' allows the auditor to verify physical security measures, environmental controls, and backup systems. This is a standard audit procedure for ensuring the operational security of banking infrastructure.

Fifth generation computers (developed in the 1980s-1990s) were designed to process knowledge rather than just data. They focused on artificial intelligence, parallel processing, and natural language processing. Earlier generations processed data (1st-3rd) or interpreted data (4th). The shift to knowledge processing defines this generation.

Among the options, accuracy is a key benefit of computers. While computers are indeed machines (option A), this is a description rather than a benefit. Option C (intelligent) is incorrect because computers follow programmed instructions without true intelligence. Option D is false because accuracy is a genuine advantage of computers over manual calculation.

The question asks which is NOT a programming language. Java and C are well-known programming languages. Microsoft Windows is an operating system, not a programming language. Therefore, Microsoft Windows is the correct answer as it is the only option that is not a language used for programming.

A computer-based information system is fundamentally defined as a system where computers process data to generate meaningful information. This distinguishes it from mere data entry or calculation systems. The emphasis is on the transformation of raw data into organized, useful information through computer processing.

Multiplexing is a technique that combines multiple input signals from different sources into one output signal and transmits them over a shared high-speed communication channel. This maximizes bandwidth utilization. Simplex and duplex modes describe transmission directions, not signal combining.

Internet Explorer (IE), Mosaic, and Netscape Navigator were all web browsers. Mosaic was the first widely popular graphical web browser (1993). Netscape Navigator dominated in the mid-1990s before IE's rise.

Third-generation computers (1960s, integrated circuits) saw the widespread adoption of high-level procedural languages like FORTRAN, COBOL, and ALGOL. Operating systems and real-time systems existed in second generation, while distributed computing emerged later.

A card reader is an input device that reads data from punched cards. The card itself is the storage medium that holds the data and functions as output when created by a keypunch machine. In conventional computer architecture terminology, readers are input devices.

Line printers, dot matrix printers, and laser printers are all distinct types of computer printing technologies. Line printers print entire lines at once (high speed), dot matrix use impact through a ribbon, and laser use electrophotography. All are legitimate printer categories.

Microsoft Excel is a spreadsheet program - a software application for organizing, analyzing, and storing data in tabular format with built-in calculation and visualization capabilities. It is not a file transfer tool, controller, or generic 'application' (too broad).

System flowcharts show the high-level relationships between input, processing, and output components of a system. Program flowcharts (C) describe internal logic. Hardware diagrams (D) show physical arrangement. Auditing procedures (A) use flowcharts to document controls.

In two-tier architecture, the client handles presentation and business logic (fat client), while the server manages data. This contrasts with three-tier where business logic moves to a middle tier. 'Tire' is a typo for 'tier'.

RAM (Random Access Memory) is primary memory - it stores data and programs currently in use for fast access by the CPU. While it's hardware component physically, its function is memory. Storage devices (hard drives, SSDs) provide persistent secondary storage.

IP address classes A through E were defined in early IP addressing. Class A (0.0.0.0-127.255.255.255), B (128.0.0.0-191.255.255.255), C (192.0.0.0-223.255.255.255), D (224.0.0.0-239.255.255.255) for multicast. Class E (240.0.0.0-255.255.255.255) was reserved for future use and experimentation.
