// Primary functions-control, error detection and response, accounting // ** Control: ** Program developmentEditors and debuggersProgram executionAccess to I/O devicesControlled access to filesSystem access
 * OS**-operating system-a program that controls the execution of application programs and an interface between applications and hardware.

** Error detection and response: ** Internal and external hardware errors (Memory error, Device failure)Software errors (Arithmetic overflow, Access forbidden memory locations)

** Accounting: ** Collect usage statisticsMonitor performanceUsed to anticipate future enhancementsUsed for billing purposes

OS Functions

File systems- organize mass storage (disk) into files and directories Utilities - date/time, accounting, file copy, etc Other tasks... Command interpreter - allows users to enter in commands interactively System calls- allows user programs access to O.S. services

CPU scheduling - allocates computing time among several processes Operating Systems **MANAGE processing Tasks** Multi-tasking - allows more than one person or program to use the resources of a single processor at the same time

File systems: File Server-- A high-speed computer in a network that stores the programs and data files shared by users. It acts like a remote disk drive. The difference between a file server and an application server is that the file server stores the programs and data, while the application server runs the programs and processes the data.

 * iSpace**: web space only for CCI students where they can post websites, coursework, projects, etc. Up to 500MB of storage space and it expires 4 years from initial login. Students create files on their machine (local) and then use SSH/SFTP to transfer files to iSpace (remote server). The option to set protections for viewing (like using private ‘person’ folder) is available.


 * Major Components of Hard wear are as followed : **
 * CPU - the CPU or central processing unit c arries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system.
 * Memory (ram) - Ram or random access memory it is the memory your computer uses to store necessary pieces of mempry that need to be accessed quickly. it is the Memory that the computer uses to preform tasks.
 * Hard drive - the mechanism that handles the reading, writing, and storage of data on the hard disk. this is where you store all of your data.
 * Monitor - the device that displays signals on a computer screen
 * Video Card - a expansion card that generates a feed of output images to a display.
 * Mouse / keyboard -external devices that the user uses to input data and control the computer.
 * Motherboard -circuit board found in all modern c omputers which holds many of the crucial components of the system, such as the CPU and memory, and provides connectors for other peripherals.
