registers
component of a CPU architecture that allows the CPU immediate access to data? memory locations that are part of the architecture of a CPU. They provide a storage location for the logical functions performed on data.
MBR (Master Boot Record)
contains information on how the hard drive partitions are organized. 512 bytes long and contains boot loader identifies the Volume Boot Record (VBR) supports a maximum primary partition of 2TB and allows four primary partitions per drive. commonly used in computers with BIOS-based firmware.
basic disk
contains primary and extended partitions as well as logical drives. is limited to 4 partitions (the default) contains partitions such as primary and extended as well as logical drives which are formatted for data storage. More space can be added to a partition by extending it into adjacent, unallocated space, as long as it is contiguous. Either MBR or GPT can be used as the underlying partition scheme of basic disks.
primary partition
contains the operating system files and is usually the first partition. Cannot be subdivided into smaller sections and 4 per hard drive gpt= all partitions are primary mbr= max 4 primary partitions
OS Basic Functions
control hardware access manage files and folders user interface application management
OpenGL (Open Graphics Library)
cross platform standard specifications for multi media graphics
GUID Partition Table (GPT)
designed as a partition table scheme standard for hard drives supports a maximum of 128 primary partitions per drive. max partition size 9.4 ZB makes use of a number of modern techniques to expand on the older MBR partitioning scheme. is commonly used in computers with UEFI firmware. Most modern operating systems now support GPT
most common installation method for home and small buisness
external media such as DVDs or USB drives.
two most common types of data storage devices used today
hard disk drives flash memory-based drives such as solid-state hard drives and USB drives.
partition scheme
has direct influence in the location of the operating systems on a disk. Finding and launching the operating system is one of the responsibilities of computer firmware. The partition scheme is very important to the firmware
administer account
have complete control over a computer. Users with this type of account can change settings globally, install programs, get through the User Account Control (UAC) when elevation to perform a task is required.
user accounts
have limited control over a computer. Users with this type of account can run applications, but they cannot install programs. A standard user account can change system settings but only settings that do not affect other user accounts
Windows 10 update assistant
installs and runs directly on the computer being upgraded. The tool will walk the user through all the steps in the Windows 10 setup process. It is designed to prepare your computer for upgrading by checking for compatibility issues and downloading all necessary files to start the install.
NFS (Network File System)
is a network-based file system, that allows file access over the network. From the user's standpoint, there is no difference between accessing a file stored locally or on another computer on the network. is an open standard which allows anyone to implement it.
device manager
is used to locate device problems and install the correct or updated drivers in Windows.
microsoft windows update
is used to scan for new software and install service packs and patches.
VBR (Volume Boot Record)
loads the boot manager, which for Windows is bootmgr.exe.
partition
logical portions of the disk that can be formatted to store data. divied up parts of the hard drive consist of tracks, sectors, and clusters. Tracks are concentric rings on the disk surface. Tracks are divided into sectors and multiple sectors are combined logically to form clusters
F8
opens windows advanced boot options menu
dynamic disk
provide features not supported by basic disk. the size of the volumes can be changed after they have been created have the ability to create volumes that span across more than one disk
Windows API
provides app developers w/ user interface controls,file management and graphical elements, such as scroll bars and dialog boxes
quick format
removes files from the partition but does not scan the disk for bad sectors. Scanning a disk for bad sectors can prevent data loss in the future. For this reason, do not use for disks that have been previously formatted.
Full Format
removes files from the partition while scanning the disk for bad sectors. It is required for all new hard drives. takes more time to complete.
RIS (remote installation service)
software used to communicate with the client, store the setup files, and provide the necessary instructions for the client to access the setup files, download them, and begin the operating system installation.
File and Folder Management
the os creates a file structure on the hard disk drive to store data.
User Interface
the os enables the user to interact with the software and hardware. CLI(command line interface)- user types command at promt GUI(graphical user interface)- the user interacts w/ menus and icons
Formatting
the process creates a file system on a partition for files to be stored
extended partition
there can be only one per hard drive but it can be subdivided into smaller sections If more than 4 partitions are required on an MBR partitioned disk, one of the primary partitions can be designated an extended partition. After the extended partition is created, up to 23 logical drives (or logical partitions) can be created within this extended partition. A common setup is to create a primary partition for the OS (drive C:) and allow an extended partition to occupy the remaining free space on a hard drive, right after a primary partition. Any extra partitions can be created within the extended partition (drives D:, E: and so on). While the logical drives can't be used to boot an OS, they are perfect for storing user data. Notice that there can be only one extended partition per MBR hard drive and that extended partitions are only found on drives with MBR partition tables.
windows 7
upgrade from vista and xp designed for personal computers
active partition
used to boot the computer and contains the boot and system files. there can only be one of these per disk In MBR disks the (? ?) is the partition used to store and boot an operating system. Notice that only primary partitions can be marked active in MBR disks. Another limitation is that only one primary partition per disk can be marked active at one time. In most cases, the C: drive is the active partition and contains the boot and system files. Some users create additional partitions to organize files or to be able to dual-boot the computer. are only found on drives with MBR partition tables.
SIM (System Image Manager)
used to create the setup answer file.
