______________________ is a way to fit data of a specific format, shape and size and make
sure it works over a specific transfer mechanism or storage mechanism. Think of it as
packaging. - ** VERIFIED ANSWERS🔰 ✔✔Encoding
A file header is which of the following?
A. A unique set of characters at the beginning of a file that identifies the file type
B. A unique set of characters following the file name that identifies the file type
C. A 128-bit value that is unique to a specific file based on its data
D. Synonymous with the file extension - ** VERIFIED ANSWERS🔰 ✔✔A. A unique set of
characters at the beginning of a file that identifies the file type
Boolean logic - ** VERIFIED ANSWERS🔰 ✔✔A form of mathematics in which an
expression is reduced to either True or False.
File Systems and Hard Drives - ** VERIFIED ANSWERS🔰 ✔✔NTFS, FAT32, ext4, HFS+,
APFS
NFTS permissions - ** VERIFIED ANSWERS🔰 ✔✔A Windows method to share a folder or
file over a network and can apply to local users and network users. The folder or file must be
on an NTFS volume. Compare with share permission.
,exFAT (Extended File Allocation Table) - ** VERIFIED ANSWERS🔰 ✔✔A 64-bit version
of the file allocation table file system designed for use on large USB flash drives.
HFS+/APFS - ** VERIFIED ANSWERS🔰 ✔✔HFS+ is a journaling system developed by
Apple Inc. and APFS is another but more encrypted Apple journaling system
ext3 and ext4 - ** VERIFIED ANSWERS🔰 ✔✔File systems commonly used by Linux/Unix
SaaS (Software as a Service) - ** VERIFIED ANSWERS🔰 ✔✔Services for delivering and
providing access to software remotely as a web-based service
IaaS (Infrastructure as a Service) - ** VERIFIED ANSWERS🔰 ✔✔A service model in
which hardware services are provided virtually, including network infrastructure devices
such as virtual servers.
PaaS (Platform as a Service) - ** VERIFIED ANSWERS🔰 ✔✔A service model in which
various platforms are provided virtually, enabling developers to build and test applications
within virtual, online environments tailored to the specific needs of a project.
What can you manage on an IaaS? - ** VERIFIED ANSWERS🔰 ✔✔Applications, Data,
Execution, Middleware, O/S
_____________ provides the capabilities to normal applications for hardware interactions or
more core functions on your system, like opening data on a disk. - ** VERIFIED
ANSWERS🔰 ✔✔The kernel
The Kernel - ** VERIFIED ANSWERS🔰 ✔✔The kernel is the first part of the operating
system code to be loaded, and has complete control over the computer. It is responsible for
controlling access to the computer's most sensitive information and functionality, and is
loaded into a protected region of memory to prevent accidental or malicious corruption by
other programs.
, The kernel is responsible for the loading of new programs, handling input and output
between peripherals, and managing access to the hardware's shared resources, such as the
RAM and hard drive.
What is a Process? - ** VERIFIED ANSWERS🔰 ✔✔A series of actions or steps taken in
order to achieve a particular end.
Each time you run a program on your computer, a new process will be created in order for
the program to serve the purpose you intend, which, in this case, would be surfing the
internet. Some programs even create many processes in order to get more work done.
____________ are a key part of how computers switch tasks and ask for things to happen. -
** VERIFIED ANSWERS🔰 ✔✔Interrupts
What is an interrupt? - ** VERIFIED ANSWERS🔰 ✔✔Signal from hardware or software
indicating that an event has occurred or that a process needs attention.
Hardware Interrupt - ** VERIFIED ANSWERS🔰 ✔✔A signal to the CPU indicating a
device needs attention. For example, a mouse click or a keystroke.
Software Interrupt - ** VERIFIED ANSWERS🔰 ✔✔In general, any instruction that causes
exception processing to occur when it is executed; such instructions may be used to request
the use of system services/resources
The bootloader is - ** VERIFIED ANSWERS🔰 ✔✔a program that is loaded by the BIOS
when a computer is first turned on, and is responsible for loading the operating system.
A bootloader is necessary due to the complexity that would be involved in creating a BIOS
capable of loading hundreds of different operating systems. Due to this, the bootloader is
usually installed at the same time as the operating system, and is loaded from a known place
on the hard drive by the BIOS.
