Resource Management Quizlet

Place where all data/programs currently being processed are kept.

HDD/SSD/Optical are places where data can be store if power is lost/RAM is volatile.

Does all the calculations in a computer system - speech is a measurement of how many calculations can be done/second.

Measurment of how much data can be sent at the same time in a certain time frame (also called bitrate). Affects how long it takes before data is processed in its entirety.

Measurment of pixels in height x width of computer display.

Sound reproduction is done by a separate processor - frees up CPU to do other calculations. Can also contain a bank of sampled sounds.

Does complex processing - examples include the NVIDIA graphics card. Alleviates pressure of CPU

Contains the instruction/data that the CPU is likely to request from RAM - makes sure that CPU doesn’t have to wait for instructions

Each network card connects to a particular type of network media

Each processor has at least 1 ALU or core - the more cores, the more tasks a system can perform simultaneously.

Thousands of cores with lots of primary/secondary memory - used with major companies.

Many high spec PCs running in parallel - used to serve networks.

System that can have different programs (apps) installed.i

Can only run one program/set of programs

Many users on same machine or connected to the same network.

Controls peripheral devices connected to the computer. Through drivers, ‘translation’ programs, etc, controlling devices like keyboards, mouses, etc.

Transfers files between main memory and secondary storage, manages file folders, allocates the secondary storage space, and provides file protections recovery.

Allocates the use of RAM to requesting processes. To manage primary memory, the OS has to ensure that each process has its own allocated memory space.

Allows the computer to run other applications.

Feature of an OS that allows compensation of shortages of physical memory by temporarily transferring pages of data from RAM to disk storage.

OS manages security access through hierarchical folder organization.

Used to interact with the computer to perform various tasks.

With a multi-user system, a time slice is the set amount of processing time each user again. With a single-user system, a time-slice is the set amount of processing time each program gets.

Function of the OS/device whose execution is triggered by the reception of an interrupt. Generally used to handle high-priority conditions.

Process where the computer waits for an external device to check for its readiness or state.

Signal to a processor emitted by hardware or software indicating an event that needs immediate attention.

When using virtual memory, the OS moves other pages to the hard disk so it has room to bring the pages it needs ASAP from temporary disk storage.

Leads to simplicity as users don’t see the hardware directly

Single alaphebetic character that has been assigned to a physical drive

Also known as a JVM, it interprets binary code so a processor can perform instructions.
