Computer Awareness Test - 2

IBM developed the first scientific supercomputer. 

Structured programming emphasizes clear, logical flow using control structures like loops and conditionals. The 'Goto' statement is discouraged because it creates 'spaghetti code' that is difficult to read and maintain.

The software development life cycle (SDLC) typically includes phases such as requirement analysis, system design, coding (implementation), testing, and maintenance. Therefore, all listed options are standard phases.

In computer programming, an error or flaw that causes a program to produce an incorrect or unexpected result is commonly referred to as a bug.

A modem (modulator-demodulator) is the device that converts digital signals from a computer into analog signals for transmission over telephone lines and vice versa.

TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is a set of communication protocols used to interconnect network devices on the internet.

Option (1) is correct.

Bandwidth in signal processing refers to the range of frequencies within a given band, which is measured in hertz (Hz).

The internet functions by utilizing the TCP/IP protocol suite to manage data transmission and addressing across global networks.

Ethernet is a standard technology used for connecting devices in a wired local area network (LAN).

IRC stands for Internet Relay Chat, which is a protocol specifically designed for real-time text messaging or chatting.

The @ symbol is the mandatory separator in an email address, dividing the local part from the domain name.

COBOL (Common Business-Oriented Language) was designed specifically for business, finance, and administrative systems for companies and governments.

 Inheritance  is associated with OOP principle.

In binary storage units, 1024 megabytes (MB) is defined as 1 gigabyte (GB).

In binary storage units, 1024 gigabytes (GB) is defined as 1 terabyte (TB).

RAM (Random Access Memory) is the primary memory of a computer, used to store data currently being processed by the CPU.

Software testing aims to verify that the program is error-free, meets user requirements, and adheres to quality standards.

Secondary memory, which is non-volatile and used for long-term storage, is commonly referred to as both external memory and auxiliary memory.

A computer system is fundamentally composed of hardware (the physical components) and software (the programs and data).

RAM is categorized into two main types: Static RAM (SRAM) and Dynamic RAM (DRAM).

Hard disks have significantly higher storage capacities compared to floppy disks, which typically hold only 1.44 MB.

 Option (1) is correct.

Software is broadly categorized into system software (like operating systems) and application software (like word processors).

Keyboards, mice, and scanners are all devices used to input data into a computer system.

Printers, speakers, and screens (monitors) are all devices used to output data from a computer system.

Data refers to raw, unorganized facts and figures, which become information after processing.

Cache memory is a high-speed memory component that sits between the CPU and the main memory (RAM) to speed up data access.

The Central Processing Unit (CPU) is responsible for interpreting and executing instructions, making it the brain of the computer.

The CPU consists of the Arithmetic Logic Unit (ALU), the Control Unit (CU), and internal registers (often including memory interfaces).

Information is defined as processed, organized, and structured data that is meaningful to the user.

ASCII and EBCDIC are both standard character encoding schemes used to represent text in binary. Since both are widely recognized schemes for this purpose, the option indicating both is correct.
