Mini computers are generally mid-sized systems designed for multi-user environments and are not considered portable, unlike laptops or notebooks.

GFLOPS stands for Giga Floating-point Operations Per Second, which is a standard measure of a computer's processing speed.

Micro, mini, and super computers are classifications based on size and power. Digital computer is a classification based on the method of data processing (analog vs. digital), making it the odd one out.

Under the Information Technology Act, CCA stands for the Controller of Certifying Authorities, who regulates the issuance of digital signature certificates.

UNIVAC (Universal Automatic Computer) was one of the earliest commercial computers, developed in the early 1950s, placing it in the first generation of computers.

SFMS (Structured Financial Messaging System) is a secure messaging standard used in banking, which typically requires robust database management systems like Oracle or MySQL to handle transactions.

 The various kinds of users in SFMS are creator, verifier , authorizer and super users.

Modern computer systems operate using the binary number system, which represents data as sequences of 0s and 1s.

Optical disks, such as CDs and DVDs, store data along a single continuous track that winds from the center outward in a spiral shape.

In standard binary storage units, 1 Terabyte (TB) is equal to 1024 Gigabytes (GB).

The order of magnitude from smallest to largest is Kilobyte (KB), Megabyte (MB), Gigabyte (GB), and Terabyte (TB). Therefore, Kilobyte is the smallest.

Magnetic tape is a sequential access medium used primarily for backups and archiving, classifying it as a secondary storage device.

FPS stands for Frames Per Second, which is a measure of the frequency at which consecutive images (frames) appear on a display.

Access time is the total time taken to locate the data and then retrieve it from the storage medium.

The CPU (Central Processing Unit) acts as the brain or administrative center of the computer, coordinating and executing instructions.

VPN stands for Virtual Private Network, which provides a secure and encrypted connection over a public network.

TCP stands for Transmission Control Protocol, a fundamental protocol of the internet suite that ensures reliable data delivery.

Cyberspace activities and digital interactions are governed by Cyber Law, which addresses legal issues related to the internet and technology.

CD-ROM (Compact Disc Read-Only Memory) uses optical technology, where a laser reads data from the disk surface.

IP stands for Internet Protocol, which is the set of rules governing the format of data sent via the internet or local network.

WWW stands for World Wide Web, which is the information system where documents and other web resources are identified by URLs.

LAN is an acronym for Local Area Network, a computer network that interconnects computers within a limited area.

In disk storage, a block of data is typically larger than a single physical sector, so it is stored across two or more sectors to accommodate the data size.

Correct answer is (3).
