1The OS manages the [blank_start]resources[blank_end] of a computer, [blank_start]starting[blank_end] and [blank_start]stopping[blank_end] programs and controlling their usage of processing, [blank_start]memory[blank_end], storage and [blank_start]peripheral[blank_end] resources.
- Aresources
- Bstarting
- Cstopping
- Dmemory
- Eperipheral
2An application usually means a program that does something "[blank_start]useful[blank_end]" and has a [blank_start]GUI[blank_end].
- Auseful
- BGUI
3A program is an [blank_start]executable[blank_end] program which may or may not have a [blank_start]GUI[blank_end].
- Aexecutable
- BGUI
4A program may start multiple copies of itself, each one is a separate [blank_start]process[blank_end].
- Aprocess
5A process can have two or more "[blank_start]mini programs[blank_end]" within it that share [blank_start]address[blank_end] space but run concurrently - these are called threads.
- Amini programs
- Baddress
6An operating system consists of [blank_start]system supplied[blank_end] applications (userland) that is managed by the [blank_start]kernel[blank_end], which mediates access by software to a computing device's resources like the CPU, memory and peripheral devices. These resources must pass through the kernel before reaching the application.
- Asystem supplied
- Bkernel
7The kernel is responsible for process management: [blank_start]starting[blank_end]/[blank_start]stopping[blank_end] processes and scheduling [blank_start]CPU[blank_end] time.
- Astarting
- Bstopping
- CCPU
8The kernel is responsible for memory management: allocating [blank_start]RAM[blank_end], enforcing [blank_start]memory security[blank_end], swapping memory to [blank_start]disk[blank_end] (virtual memory).
- ARAM
- Bmemory security
- Cdisk
9The kernel is responsible for [blank_start]I/O[blank_end] communication to [blank_start]peripheral[blank_end] devices and other devices on a network.
- AI/O
- Bperipheral
10The kernel is also responsible for the filesystem: [blank_start]low level[blank_end] storage, [blank_start]recall[blank_end] and management of files on storage devices.
- Alow level
- Brecall
11An operating system will usually provide a [blank_start]userland[blank_end] suite of basic programs to interact with the OS.
- Auserland
12The userland is capable of basic management of programs like [blank_start]dir[blank_end], cp, [blank_start]mv[blank_end].
- Adir
- Bmv
13The userland is also comprised of system services like the scheduled [blank_start]task runner[blank_end] and [blank_start]iCloud[blank_end] synchronisation.
- Atask runner
- BiCloud
14The userland is also in charge of [blank_start]packet[blank_end] management. (App store).
- Apacket
15The [blank_start]user interface[blank_end] is the most obvious part of any OS.
- Auser interface
16[blank_start]Multitasking[blank_end] is the ability of the OS to run more than one process simultaneously.
- AMultitasking
17Co-operative multitasking is when process [blank_start]hand off[blank_end] to each other.
- Ahand off
18Pre-emptive multitasking is when the [blank_start]kernel[blank_end] enforces resource allocation.
- Akernel
