Explanation:
8) The bit is a basic unit of information in computing and digital communications. The name is a portmanteau of binary digit. The bit represents a logical state with one of two possible values.
3) 0.001 kilobyteBlu-Ray discs have more storage capacity — a LOT more. A standard DVD holds 4.7 gigabytes of data. ... If that movie is longer than two hours, you need two DVDs or a double-layer DVD that can store around 9GB. On the other hand, a double-layer Blu-ray disc can hold a massive 50 GB of data.
4) Memory, also referred to as primary storage, typically refers to storage that is directly accessible by the computer's CPU.
5) The startup instructions stored on ROM in a PC are part of the BIOS (Basic Input Output System). The BIOS also contains the low-level interface code needed to access the drives, keyboard, and produce simple display output.
1) Computer storage and memory is often measured in megabytes (MB) and gigabytes (GB). A medium-sized novel contains about 1 MB of information.
2) RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
3) Primary memory data is directly accessed by the processing unit whereas Secondary memory data cannot be accessed directly by the processor. ... Primary memory is both volatile & nonvolatile whereas Secondary memory is always a non-volatile memory.
4) External hard drive.
Flash drive.
Floppy disk.
Compact disc.
Tape drive.
