Test: Operating System - 2 - Bank Exams MCQ

Linux is a family of open-source Unix-like operating systems based on the Linux kernel. It is widely used for supercomputers, mainframe computers, and servers.

A digital device that processes data is known as data processor.
The processor, more formally known as the central processing unit (CPU), has the electronic circuitry that manipulates input data into the information required by the users. The central processing unit executes computer instructions that are specified in the program.
Some of the most common processing devices in a computer include central processing unit (CPU) and graphics processing unit (GPU).

Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. In contrast, volatile memory needs constant power in order to retain data. ROM is non-volatile; even after you turn off your computer, the contents of ROM will remain.

Analog computer works on the supply of Continuous electrical pulses.
An analog computers, works by measuring voltages and currents rather than by the process of counting. An analog computers works on supply of continuous electrical signals and display outputs continuously. Side rule is an example analog device in which numbered as expressed as distances.
A computer that operates with numbers represented by directly measurable quantities (such as voltages or rotations) — compare digital computer, hybrid computer. This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.

MS-DOS is a computer operating system by Microsoft Corporation. It stands for ''Microsoft Disk Operating System'' and came from an operating system Microsoft bought called QDOS.
Windows 98 is a graphical operating system developed by Microsoft as part of its Windows 9x family of operating systems. It is the successor to Windows 95, and was released to manufacturing on May 15, 1998, and to retail on June 25, 1998.
UNIX is an operating system which was first developed in the 1960s, and has been under constant development ever since. By operating system, we mean the suite of programs which make the computer work. It is a stable, multiuser, multitasking system for servers, desktops and laptops.
Adobe Reader is a free program created and distributed by Adobe Systems. It is used to open PDF documents. PDFs can be a wide variety of files, such as images, text documents, forms, books, or any combination of these.

The command 'pwd' stands for Print Working Directory. It is used to print the path of the currently working directory starting from the root. It is a built-in command.

Bharat Operating System Solutions (BOSS Linux) is a GNU/Linux distribution developed by C-DAC, Chennai in order to benefit the usage of Free/Open Source Software in India.

Internal memory, also called "main or primary memory" refers to memory that stores small amounts of data that can be accessed quickly while the computer is running.

In a computer, program-addressable storage from which instructions and other data may be loaded directly into registers for subsequent execution or processing is known as main storage. Main storage includes the total program-addressable execution space that may include one or more storage devices.

A memory that does not change its contents without external causes is known as static memory.
Static Random-Access Memory (static RAM or SRAM) is a type of semiconductor memory that uses bistable latching circuitry (flip-flop) to store each bit. SRAM exhibits data remanence, but it is still volatile in the conventional sense that data is eventually lost when the memory is not powered.
