Answer:
Just before the closing </head> tag
Explanation:
The Analytics tracking code is usually a small pieces of JavaScript snippet install on a page of a website (just before the closing </head>tag) but runs in the viewer's browser. it is responsible for tracking and collection of all of the users data when they visit the pages.
Your company leases a very fast internet connection and pays for it based on usage. You have been asked by the company president to reduce internet line lease costs. You want to reduce the amount of web pages that are downloaded over the leased connection without decreasing performance.
What is the best way to do this?
a. Install modems in employees' computers
b. Implement NAT
c. Install a proxy server
d. Install a packet-filtering firewall
Answer:
c. Install a proxy server
Explanation:
In computing a proxy server is implemented as a middle 'man' between the user and the internet. It will hence behave as a gateway that will seperate users from the websites that they browse. The major importance of a proxy server is enforcing security, however it can also act as a web filter allowing organizations to restrict access to certain websites. So when an organization or a school wishes to prevent access to certain sites a proxy server will be implemented, in the question scenario this web filter feature can be used to save cost associated with visiting sites not relevant to the organization's objectives
Someone asks you for help with a computer that hangs at odd times. You turn it on and work for about 15 minutes, and then the computer freezes and powers down. What do you do first?
a. Replace the surge protector.
b. Replace the power supply.
c. Wait about 30 minutes for the system to cool down and try again.
d. Install an additional fan
Answer:
C. Wait for about 30 minutes for the system to cool downand try again.
Explanation:
In computer system troubleshooting, there are two areas where problems can arise. They are hardware and software related issues.
software issues are application related like an application not installed properly, malicious software attack, corrupted operating system etc, while hardware has to do with a faulty hardware component in the system.
Example of a hardware related issue, when the active fan is faulty, the computer overheat and eventually shuts down to cool the system. When it cools down, the computer can boot again.
To confirm that the fan is faulty, when it shuts down to cool, wait for some time and try booting the system again. If it comes on, then the fan is bad.
The first step in diagnosing a computer that hangs and powers down is to wait for it to cool down and then retry, to see if overheating is the issue. If the problem persists, further diagnosis is needed to identify the underlying cause.
When faced with a computer that hangs and powers down unexpectedly, the most prudent first step is not to immediately replace parts without diagnosis. Instead, option c, wait about 30 minutes for the system to cool down and try again, would be the most logical initial approach. This step allows you to determine if overheating is the cause of the system instability.
If the computer works fine after it has cooled down, you might have identified an overheating issue. From there, you can check for obstructed air vents, clean out dust from within the computer, or consider the possibility of a malfunctioning fan or thermal paste that needs replacement. Continuous problems after the system has cooled down would suggest further investigation into the power supply, surge protector, and other potential causes of the failure is necessary.
With respect to IT security, a risk can result in either a positive or a negative effect.
A. True
B. False
Answer:
Option A is the correct answer choice for the above question.
Explanation:
IT(Information technology) Security is used to secure Information technology which means to secure the information which is traveling through the internet for communication on the internet. It uses various security tools.
When any security method is developed for the first time then there will be a risk to develop it. Sometimes the result of risk will be positive and sometime it will be negative because--
It is positive when the risk is being solved and the user achieved about the security which he is trying to develop.It is negative when the security designer did not achieve the right result for that research.The above question also states the same which is described above hence true is the right answer for the above question.
Which describes the safest way to sit at a desk while typing on the computer?
A. Keep the knees and hips at 90-degree angles and the wrists straight.
B. Elevate the knees, keep the hips at a 90-degree angle, and keep the shoulders back
C. Keep the monitor above the eyes and the keyboard slightly raised
D. Keep the monitor at eye level and the keyboard slightly raised.
Final answer:
The safest way to sit at a desk while typing is to keep the knees and hips at 90-degree angles and the wrists straight, as this aligns the center of gravity above the hips, promoting good posture and reducing the risk of back strain and muscle strain.
Explanation:
The safest way to sit at a desk while typing on the computer is described in option A: Keep the knees and hips at 90-degree angles and the wrists straight. This position aligns the person's center of gravity above the pivot point in the hips, which is ideal for maintaining good posture and avoiding back strain and damage to the disks.
It is essential to ensure that the monitor is at eye level to avoid neck strain, and the keyboard should be positioned in such a way that the wrists remain straight to prevent muscle strain. Special ergonomic chairs can assist in achieving this posture by making it easier to position the body's center of gravity correctly.
Your friends know that you understand a lot about computers, both the technical details of how they operate as well as information about software. Lately, with all of the concerns about copyright infringement, friends have started to ask you categories of application software and what each kind permits.You tell your friends that all of the following are true EXCEPT:a) Customers using freeware can personalize the software to meet their needs.b) Anyone can copy or distribute public-domain software to others at no cost.c) Some shareware programs become useless if no payment is sent after the trial period ends.d) A copyright gives creators of original work exclusive rights to duplicate, publish, and sell their materials.
Final answer:
The incorrect statement is that customers using freeware can personalize the software to meet their needs. Freeware is free to use but not necessarily free to modify, whereas public-domain software can be freely copied and shared. Copyrights and patents protect different types of intellectual property, while trade secrets rely on confidentiality.
Explanation:
The statement given to friends about categories of application software where all the following are true EXCEPT: 'Customers using freeware can personalize the software to meet their needs' is not accurate. Generally, freeware is software that is available to users at no cost, but it doesn't necessarily mean that users have the rights to modify it. Public-domain software can be copied and distributed at no cost because it is not protected by copyright. Shareware often requires payment after a trial period, and failure to pay may render the program inactive. Copyright protection, on the other hand, provides creators of original work with exclusive rights, but it does not generally apply to inventions, which are typically covered by patents. Trade secrets, such as the formula for Coca-Cola, are protected through confidentiality and not through copyright or patent law.
