XT(extra technology) computer: it cannot support GUI Based operating system. its processing speed is 477MHz
AT(advanced technology):it supports GUI Operating system. Its processing speed is 2GHz
PS/2:is a laptop computer which is rechargeable
and battery powered. it's operated with OS/2 operating system.
PLEASE MARK AS BRAINLIEST
Answer:
XT Computers (Extended Technology)
AT Computers (Advanced Technology)
PS/2 Computers (Personal System 2)
Explanation:
XT Computers :
The computers having 8086 or 8088 microprocessor and processing speed of 4.77 Mhz are known as XT Computers. These computers are outdated now because they cannot run on latest software versions.
AT Computers :
The computers having 80286 or later versions of microprocessors are known as AT Computers. Their storage capacity as well as speed is much higher than XT computers. Besides that they have math co-processor to support main processors to perform complex mathematical calculations.
PS/2 Computers:
IBM developed another model of computer in 1990 that have much advanced architecture design that AT computers. They are known as PS/2 computers. They are much faster than AT computers. Most of the laptop computers based on PS/2 model use OS/2 or UNIX operating system and 1.44 MB floppy diskette.
why the internet is not policed
Answer:
The Internet allows people to circumvent law by committing criminal acts from areas where their activities are not illegal. Those areas will always exist, and thus new regulations will be just as ineffective as the old ones are ["Net Needs Law Enforcement, Author Says,"]. But Internet traffic is marked with IP addresses, and those addresses can be tied to specific networks with specific locations. Shouldn't it be possible to separate traffic based on the originating network and treat data coming from relatively insecure locations differently than data coming from relatively secure locations? It would be much harder for someone in a rogue nation to hack a network if he had to hack an intermediary network first. And unlike government regulation, which has zero impact in areas where these threats are likely to originate, separating traffic by location might actually work
Which of the following stores the operating system?
O Von Neumann center
O Bluetooth center
O the cloud
O random access memory
Answer:
The Cloud
Explanation:
Clouds are basically computers offsite. The cloud is used for many things, Like storage, to running applications which needs an operating system to work. Just like the device you are using right now to use Brainly. It needs an operating system to install a web broswer or app to acess a service. Hope this helps!

What does RoHS stand for and why is RoHS compliance important?
Answer:
It stands for Restriction of Certain Hazardous Substances.
Web search says it is important because,
RoHS compliance dovetails into WEEE by reducing the amount of hazardous chemicals used in electronic manufacture. Put another way, RoHS regulates the hazardous substances used in electrical and electronic equipment, while WEEE regulates the disposal of this same equipment.

4. Calculate the standard deviation for the following data set: Foundations of Technology Engineering byDesi OITEEA . . Data Set = 4, 14, 6, 2, 7, 12 217 ,
Answer:
[tex]\sigma_x = 5.68[/tex]
Explanation:
Given
[tex]x = 4, 14, 6, 2, 7, 12 2,17[/tex]
Required
The standard deviation
First, calculate the mean
[tex]\bar x =\frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{4+ 14+ 6+ 2+ 7+ 12 +2+17}{8}[/tex]
[tex]\bar x = \frac{64}{8}[/tex]
[tex]\bar x = 8[/tex]
The standard deviation is:
[tex]\sigma_x = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
So, we have:
[tex]\sigma_x = \sqrt{\frac{(4 - 8)^2+ (14 - 8)^2+ (6 - 8)^2+ (2 - 8)^2+ (7 - 8)^2+ (12 - 8)^2+ (2 - 8)^2+ (17 - 8)^2}{8-1}}[/tex]
[tex]\sigma_x = \sqrt{\frac{226}{7}}[/tex]
[tex]\sigma_x = \sqrt{32.2857}[/tex]
[tex]\sigma_x = 5.68[/tex]
Which of the following are characteristics of centralized version control systems? Select 3 options.
A full copy of all project files is stored on each developer's computer.
Changes to the project are stored in a log file on each developer’s computer.
It allows many developers to work on the same project from anywhere at the same time.
Project files are maintained in a central repository.
The process may require file locking, depending on file type.
Answer:
It allows many developers to work on the same project from anywhere at the same time
Project files are maintained in a central repository
The process may require file locking, depending on file type
Explanation:
The two main types of version control system are the centralized version control system and distributed control system
The centralized version control system is a control system whereby all programmers work on and make their individual changes to a single single copy of the project stored and maintained in a central repository, such as a server
In order to solve the problem of several developers working on each others work simultaneously, a centralized version control system makes use of the lock-modify-unlock model
The three options are therefore;
It allows many developers to work on the same project from anywhere at the same time
Project files are maintained in a central repository
The process may require file locking, depending on file type

A. Configure network policies on the RADIUS server.
B. Make each remote access server a member of the RemoteServers group.
C. Configure the exact same network policies on each server.
D. Configure one of the remote access servers as a RADIUS server, and all other servers as RADIUS clients.
E. Use Group Policy to configure network policies in the default Domain Controllers GPO.
F. Configure each remote access server as a domain controller.
Answer: configure one of the remote access servers as a RADIUS server and all other servers as RADIUS clients

express in Qbasic assignment statement
[tex]v = \ \sqrt{t} ^{2} - 4s \div {d}^{4} [/tex]
[tex]K = {8}{x} ^{3} - {2}{y}^{ 6} \div {5}{d}+ {e}^{4} [/tex]
Answer:
v = sqr(t^(1/2)) - 4 * s / d^4
K = 8 * x^3 - 2 * y^6 / 5 * d + e^4
Explanation:
Given
[tex]v = \ \sqrt{t} ^{2} - 4s \div {d}^{4}[/tex]
[tex]K = {8}{x}^{3} - {2}{y}^{ 6} \div {5}{d}+ {e}^{4}[/tex]
Required
The equivalent in Q Basic
To solve this, we use the following rules:
+ , - and * are written as + , - and *
[tex]\div[/tex] is written as /
^ stands for raise to power
SQR is used for square
^(1/2) stands for square root.
So, the equivalents of the above statements are:
v = SQR(t^(1/2)) - 4 * s / d^4
K = 8 * x^3 - 2 * y^6 / 5 * d + e^4
