 Option (4) is correct.

Option (1) is correct.

Computer architecture refers to the conceptual design and fundamental operational structure of a computer system. It acts as a blueprint for how the various hardware components interact. Assemblers and utilities are types of software, not the design of the system itself.

A mainframe computer is a large, powerful data processing system built using conventional, centralized architecture. These machines are designed to handle massive amounts of data and support many users simultaneously. Supercomputers often use non-conventional, highly parallel architectures for specialized tasks.

A data network is a telecommunications network which allows computers to exchange data. It is specifically designed to carry digital information between nodes. Terms like data point or data pack refer to specific elements or units within a system rather than the network itself.

Cassette tapes are linear storage media, meaning the data must be accessed in the order it was recorded. This is known as sequential access, where you must pass through previous records to reach a specific one. Direct and random access allow jumping to any part of the data immediately, which tapes cannot do.

BASIC is traditionally implemented as an interpreted language, allowing lines of code to be executed directly by an interpreter. In contrast, languages like PASCAL, FORTRAN, and COBOL are traditionally compiled directly into machine code.

Dialup refers to a communication link that uses a standard telephone line to connect a computer to a remote network. It was a primary method for remote access before the widespread adoption of broadband. Devices and logic units are hardware components, not connection methods.

A latch is a basic electronic circuit used to store one bit of information. It remains in a specific state (0 or 1) until a signal changes it, acting as a temporary memory cell. Accumulators and buffers are larger structures that use multiple latches or flip-flops.

Ethernet was originally developed at Xerox PARC (Palo Alto Research Center) by Robert Metcalfe and others in the 1970s. It became the standard for local area networks (LANs) in office environments. UNIX and DOS are operating systems, not networking hardware standards.

A transducer is a device that converts energy from one form to another, such as an electrical signal into a physical movement or vice versa. In computing and electronics, it is essential for interfacing with the physical world. A modem specifically converts digital signals to analog for transmission, which is a narrower function.

A CPU cycle, also known as an instruction cycle, is the process by which a computer retrieves a program instruction from its memory, determines what actions the instruction requires, and carries out those actions. Delay time and seek time refer to latency in data access or mechanical movement, while real time refers to actual clock time. Therefore, the cycle time of the CPU defines the duration of these basic operations.

A data bank is a large repository of information on a specific subject, often compiled from multiple sources. While the term database is more common in modern technical contexts, data bank specifically emphasizes the collection of data for a particular topic or field. Data acquisition refers to the process of gathering data, not the storage itself.

CP/M (Control Program for Microcomputers) was a widely used single-user operating system for early 8-bit microcomputers. While MS-DOS and PC-DOS are also single-user systems, CP/M was the industry standard for the first generation of microprocessor-based systems. UNIX, by contrast, is a multi-user and multi-tasking operating system.

Option 3 is the correct answer.

The mouse is a pointing device that allows users to navigate graphical user interfaces (GUIs) without typing commands on a keyboard. By using a cursor to select icons and menus, the mouse significantly reduces the need for keyboard input for basic navigation. Joysticks and light pens are also input devices, but the mouse is the primary tool that replaced keyboard-only operation.

Microcomputers, which include personal computers, laptops, and tablets, are designed for individual use and emphasize a compact, portable form factor. Mainframes and supercomputers are massive systems designed for high-performance processing and occupy significant physical space. Mini computers are smaller than mainframes but larger and less compact than microcomputers.

An interface is the shared boundary or point of connection where two separate systems or components interact and exchange information. It defines the protocols and methods for communication between hardware, software, or even humans and machines. Terms like interdiction and intradiction are unrelated to system boundaries.
