Computer Fundamentals and System Concepts

The statement is incorrect about first generation computers. Real time processing was not possible in first generation computers. It was possible in third generation computers.

This line indicates that the 8085 micro processor is going to send data away from itself.

This line indicates that the 8085 micro processor is expecting data to be fed to it.

The operating system (OS) is essential software that manages computer hardware and software resources. Without an OS, the computer cannot perform the boot sequence which loads system files, initializes hardware, and prepares the system for use. Compilers, loaders, and assemblers are development tools that run after the OS is running.

Hacking refers to the practice of modifying computer system software or hardware to accomplish a goal outside the creator's original purpose. While often associated with unauthorized access, the term broadly covers any alteration to achieve unintended functions. Pegging, trekking, and breaking are not related to computer system modification.

This is the correct answer.

A worm is a system threat as it generates its multiple copies and each copy uses system resources, prevents all other processes to get required resources. System threat misuses system services and its resources to make the user in trouble.

Central Proccessing Unit (CPU) has all the components of the system. It computes all operations from basic to complex. It is also called the motherboard of the computer.

An arithmetic logic unit (ALU) is a major component of the central processing unit of a computer system.

In 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built

The period of second generation: 1959-1965. Transistor based

Java is a set of several computer software products and specifications from Sun Microsystems (which has since merged with Oracle Corporation),

The system unit (also called the computer case or tower) is the container or enclosure that houses the main electronic components of a computer, including the motherboard, processor, memory, and power supply. It coordinates and connects all the internal hardware but doesn't directly control input/output devices, manipulate data (that's the CPU's job), or perform arithmetic operations (also the CPU). Note: There's a typo in option B where 'contain' should read 'container.'

The processor (CPU) is the component that actually executes program instructions by fetching, decoding, and running them. The scanner is an input device, main storage holds data temporarily, secondary storage stores data long-term, and the printer is an output device.

The booting process performs the Power-On Self-Test (POST) which checks hardware components when the computer starts up. An integrity test is not a standard boot process term, correct functioning test is vague, reliability test is not part of booting, and shut down test happens when turning off.
