BCIS NOTES:
Mobile Computing: refers to the use of battery-powered mobile devices that provide access to computing, communication, information, and/or entertainment anywhere, anytime.
Mobile Computing Technologies are dependent on:
Rechargeable Batteries
Wireless Networks
Servers
Syncing
Storage

Synchronization: is the process of maintaining common files and data across multiple devices so that all copies are up to date.

Server: is a powerful computer that often utilizes many processors to provide services to many users simultaneously over a network.
Application server
Communications server
Database server
Email server
File server
Print server
Game server
Web server

Random Access Memory (RAM): is temporary, or volatile, memory that stores bytes of data and program instructions for the processor to access.
Video Memory: sometimes called video RAM, VRAM, or graphics memory, is used to store image data for a computer display in order to speed the processing and display of video and graphics images.

Microsoft Windows, Mac OS X, and today’s demanding 3D computer games require high-capacity video memory and sophisticated graphics support to provide a rich and realistic graphics environment for work and play.

Read Only Memory (ROM): provides permanent storage for data and instructions that do not change, such as firmware — programs and data from the computer manufacturer, including the boot process used to start the computer.
ROM stores data, using circuits with states that are fixed. Therefore, the data represented by this combination is not lost if the power is removed.

Magnetic Storage: is a storage technology that uses the magnetic properties of iron oxide particles rather than electric charges to store bits and bytes more permanently than RAM.
Magnetically stored data lasts years, even decades, before deteriorating. Magnetic storage, in the form of a hard disk drive, provides an inexpensive, high-capacity form of permanent storage that acts as the main storage medium for most computer users.

Optical Storage: media, such as CDs, DVDs, and Blu-ray discs, store bits by using an optical laser to burn pits into the surface of a highly reflective disc.
Although optical storage does not match the high capacity and data access rates of magnetic and solid-state storage, it is ideal for storing music, movies, photos, software, and data for mobile access and sharing.

Solid-State Storage: device stores data using solid-state electronics such as transistors, and unlike magnetic and optical media, does not require any moving mechanical parts.
Solid-state storage offers fast access times, is increasing in capacity each year, and the cost continues to decrease.

Business Software: any software designed to assist individuals and groups to be more productive at work and is often used in reference to software suites that include word processing, spreadsheet, database, and presentation software.

Personal Software: is any software designed for personal benefit, including home management, entertainment, and education.

Mobile Apps: are software that is designed for smart phones and tablets.
Consider what computing activities are appropriate for each device size: PC, tablet, and mobile phone. Also consider apps that can work across devices with slight modifications, and which are best suited for a single size and/or environment.

Boot Process: also known as booting, booting up, or bootstrapping, is the sequence of instructions in the BIOS that is executed when a computer is powered on to check the system and load the operating system into memory.
The boot process instructions are part of the BIOS (the basic input/output system), which is burned into ROM so it is always ready for the processor to execute when the computer is powered on.

File Management: refers to the physical and logical storage system and practices provided for managing data on a computer.
When you save a file to your…
