Computer Fundamentals Quiz

Computer Basics

• The main working memory used by the computer is RAM (Random Access Memory).
• Keyboard is an input device in a computer.

Types of Computers

• Supercomputers are the fastest type of computer that can perform complex operations at very high speed.
• Mainframes are a type of computer that can perform complex operations at high speed.

Windows

• Windows can be resized and repositioned on the desktop.
• More than one window can be open at a time.
• Toolbars and scrollbars are features of windows.

Operating System

• The operating system manages memory and storage.
• The operating system enables users to perform tasks such as document editing.
• The operating system does not provide a command-driven environment.

Files and Folders

• Files should be organized in folders.
• Files can be generated from an application.
• A file is a collection of related pieces of information stored together for easy reference.
• Files are not stored in RAM.

• ROM (Read-Only Memory) is a type of memory that is programmed at the time it is manufactured.
• Cache is a high-speed memory used in computers.
• PROM (Programmable Read-Only Memory) is a type of memory that is non-volatile and may be written only once.
• EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of memory that is non-volatile and can be rewritten.
• EPROM (Erasable Programmable Read-Only Memory) is a type of memory that is non-volatile and can be rewritten.

Input/Output Devices

• Printer is a device primarily used to provide hardcopy.
• CRT (Cathode Ray Tube) is a type of display device.
• Console is a type of input/output device.

Memory and Storage

• A byte is a collection of 8 bits.
