Computer Fundamentals and System Concepts

It is a data transmission in which a single wire can carry several channels at once.

The control unit coordinates all computer operations like a brain coordinates body functions. It fetches instructions, decodes them, and directs other components. The heart pumps blood (power supply), and central nervous system is closer to the bus system that carries data.

Option 2 is correct. 

A compiler is system software that translates high-level code into machine code. Spreadsheets, word processors, and DTP (Desktop Publishing) are all application software for end-users, while compilers directly support the computer's operation.

ROM (Read-Only Memory) stores permanent instructions like BIOS that the computer needs to start up and operate. These are 'firmware' - essential programs written by manufacturers. User programs run in RAM, but ROM provides the foundational instructions to boot and manage hardware.

Personal computers, contains articles related to those Micro computers being used by individual people primarily for (home)office/productivity applications.

The Control Unit (CU) is the component within the CPU that interprets program instructions and directs the operation of the processor. It decodes instructions, determines the required operations, and coordinates data flow between the ALU, registers, and memory. Registers (Option B) store data temporarily, while the ALU (Option C) performs arithmetic and logical operations.

Third generation computers (1960s) used Integrated Circuits (ICs) - multiple transistors fabricated on a single silicon chip. This replaced the discrete transistors used in second generation computers. Vacuum tubes (Option B) were first generation, Large scale integration (Option A, LSI) was fourth generation, and Transistors (Option D) were second generation.

Firmware is software that is permanently stored in hardware read-only memory (ROM) or flash memory, providing low-level control for device-specific operations. It bridges hardware and software. 'Cellular program' is not standard terminology, regular software is not hardware-stored, and shareware is a licensing model.

Norton is antivirus software that detects, prevents, and removes computer viruses and other malware, making it the appropriate solution when a virus infects a computer.

Each computer generation has seen reduced physical size, INCREASED memory/storage capacity, and faster processing speeds - making option B the false statement since capacity actually increases, not decreases.

Peopleware refers to the human personnel involved in computing - those who design, program, operate, and maintain computer equipment. This includes programmers, operators, analysts, and support staff. The other options are specific roles, while peopleware is the collective term for all computer personnel.

It is a system threat.
