Simple question, something I learned recently as I was solving an issue with a user's mailbox.
User mailbox storage limit for an E3 license is 100 GB, it's archive limit is unlimited and its address list limit is 1000.
The doas(1) utility first appeared in OpenBSD 5.8, intended as a lightweight drop-in replacement for sudo(1), which stopped being included in the base system since OpenBSD 5.7. The sudo utility had a large codebase, with lots of customizable bells and whistles. Most users would never use the advanced features of sudo, so in an attempt to minimise the attack surface and make a simpler tool, Ted Unangst wrote doas.
Despite being smaller and with fewer options, it still
aimed to retain the fine-grained control that people had come to expect
of utilities such as sudo, as
Ted Unangst
describes in his blog post: https://https.www.google.com.tedunangst.com/flak/post/doas
The Extended Industry Standard Architecture (EISA) is a bus
standard for IBM PC compatible computers. It was announced in September
1988 by a consortium of PC clone vendors (the "Gang of Nine") as a
counter to IBM's use of its proprietary Micro Channel architecture (MCA)
in its PS/2 series.
EISA extends the AT bus, which the Gang of Nine
retroactively renamed to the ISA bus to avoid infringing IBM's trademark
on its PC/AT computer,
to 32 bits and allows more than one CPU to share
the bus. The bus mastering support is also enhanced to provide access
to 4 GB of memory. Unlike MCA, EISA can accept older XT and ISA boards —
the lines and slots for EISA are a superset of ISA.

The PHP function print_r() is responsible for outputting the contents of an array at runtime. It is often used for debugging an array during development.
Example:
<?php
$MyArray = array("apple", "orange", "banana");
print_r($MyArray);
/*-------------------------------------------*/
The above would be outputted as:
Array([1]=>apple,[2]=>orange,[3]=>"banana")
/*-------------------------------------------*/
?>When comparing two pieces of data in Excel, what operator would you use to test if they were not equal?
If I were comparing cells A1 to B1, my formula would be:
=A1___B1
NOT() is a function, not an operator.
The common naming convention of cmdlets and functions in PowerShell is "Verb-Noun".
There are 3 primary rules for naming within this convention:
Each I/O device connected to your computer is mapped to a unique I/O
(Input/Output) address.
These addresses are assigned to every I/O port
on your computer, including USB, Firewire, Ethernet, VGA, and DVI ports,
as well as any other ports your computer might have.
In a network, when two or more stations attempt to transmit a packet
across the network at the same time, a packet collision occurs. This is
not uncommon in a shared medium such as an Ethernet that has many
computers in the same network segment.
When a packet collision occurs,
the packets are either discarded or sent back to their originating
stations and then re-transmitted in a timed sequence to avoid further
collision. Packet collisions can result in the loss of packet integrity
or can impede the performance of a network
From Wikipedia: "nano is a text editor for Unix-like computing systems or operating environments using a command line interface. It emulates the Pico text editor, part of the Pine email client, and also provides additional functionality"
Flags = Correct
A header manipulation modifies flags and data in a packet and can launch a session hijacking attack.
Buffer overflow attacks can modify memory buffers.
SQL injection attacks can modify databases.
Antivirus software requires up-to-date signature definitions, but header manipulation does not modify these.
Get-History - Get a list of the commands entered during the current session. Returns a HistoryInfo object for each history item that it gets.
Powershell About Arrays - "Negative numbers count from the end of the array. For example, '-1' refers to the last element of the array."
HistoryInfo.CommandLine Property - Returns the command line string that was issued for that command history item
clip - Windows Vista included a tiny command line utility called clip. All it does is paste its stdin onto the clipboard. (Not actually a Powershell command so can be used in Command Prompt as well.
Active Directory replication does not depend on time
to determine what changes need to be propagated. It relies instead on
the use of update sequence numbers (USNs) that are assigned by a counter
that is local to each domain controller.
Because these USN counters are
local, it is easy to ensure that they are reliable and never "run
backward" (that is, decrease in value). The trade-off is that it is
meaningless to compare a USN assigned on one domain controller to a USN
assigned on a different domain controller.

In IP v4. The range is from 10.27.9.16 to 10.27.9.23 with a 29 bit subnet mask. 255.255.255.248
Giving a total of 8 hosts on the sunbet, although only 6 are usable.
By default, the permissions on a home folder are drwxr-xr-x
or 755.
This allows other users on the system access to the top level of
the the home folder so that they can access the Public and Sites
folders to read or send files to the owner. The main other folders
(Desktop, Documents, etc) are locked to drwx------ so that only the
owner has access.
Rather than using 'F' for 'find' Nano uses 'W' for 'Where Is'.
Mixed reality (MR) not just overlays, but anchors virtual
objects to real-world objects and allows the user to interact with
combined virtual/real objects.
The command Get-Process shows all current running processes. You can pipe the output into other commands to get even more detail and information.
dmesg (Display message or driver message) is a command
which will show Kernel ring buffers. These messages contain valuable
information about device drivers loaded into the kernel at the time of
booting as well as when we connect a hardware to the system on the fly.
In other words dmesg will give us details about hardware drivers
connected to,
disconnected from a machine and any errors when hardware
driver is loaded into the kernel. These messages are helpful in
diagnosing or debugging hardware and device driver issues
Syntax errors are a the most common problem when programming. For basic programming, an open bracket is required for any parameters to be passed to a function, and strings (text) requires quotes to distinguish itself from any variables in the code.
PnPUtil (PnPUtil.exe) is a command line tool that lets an administrator perform the following actions on driver packages:
Adds a driver package to the driver store.
Installs a driver package on the computer.
Deletes a driver package from the driver store.
Enumerates the driver packages that are currently in the driver store. Only driver packages that are not in-box packages are listed. An in-box driver package is one which is included in the default installation of Windows or its service packs.
