The correct answer is: Scanner
The scanner is a piece of technology which unlike the printer is an input device which basically scans the top-view of any flat surface (usually paper but is definitely not limited to it) introduced in its effective range using light. The data scanned is then transfered to the Central Processing Unit for futher processing. The processed image can then be outputted and seen on the monitor's display. Once available for printing, the Central Processing Unit will just send the processed image into the printer ad voila, your scanned image is now printed in a piece of paper!
Today, scanners come with printers as a bundle. It is a perfect combination since the printer will just print the image anyway.
Answer:Systems analysts
Explanation: System analyst is referred as the person in an organization for resolving the issue related program and information technologies. The person basically design the solution by analyzing the problem accordingly.
Information system of company has any separate department for handling the problems related with the IS-related programs. These problem usually lies under the department of the system analyst. They work on the problem solving, improvement and improvisation, training etc.
Answer:
import string
all(c in string.hexdigits for c in s)
Explanation:
The hexadecimal number system, often abbreviated as "hex", is a numeral system which consist of 16 symbols (base 16). The standard numeral system we are all use to, called decimal (base 10) and utilizes ten symbols: 0,1,2,3,4,5,6,7,8,9.
Using python programming language
import the string module
the second expression iterate through the digit in s and confirm if they all are within the rage of 0 -9 ad A -F. If yes , it returns True and else, it returns false
Domain Name Servers (DNS) are certainly necessary for easy access of resources across a network. The applicable options of the above are A and B - below are explanations as to why.
A: Computers generally are set to automatically obtain DNS information from the network they are connected to or can be pointed to a specific DNS server. This allows for records of where resources (network attach storage devices, other computers on local network, or even website server details) are located on a “master” kind of list so that the local machine’s host file does not have to be routinely updated to contain new addresses.
B: DNS, as explained partially by the answer to A, maintains a type-able or “human readable” domain name for the actual server’s IP address so we don’t have to memorize or keep a list of IPs for where we want to visit on the web (although, Google’s 8.8.8.8 IP address does make it easy). It shows an association between a name/domain name and an IP address so that we can enter something simple (Google.com) and the computer knows where to go (the server at IP address 8.8.8.8) so it can show you the content you want to see.
C: DNS would only simplify remote access if your were attempting LAN (Local Area Network) remote access of another computer on your network. DNS would not make it easier for remote access of a computer on the internet, as most DNS used in non-commercial settings are created and maintained by third-parties that will not put a specific record for one of your computers in it - not that you would want them to either, since it could lead to an open cyber attack.
D: Network throughput is a fancy phrase for network speed. It could be possible that different DNS servers could process requests faster than others, but it is not likely to increase network speed on the whole as navigating via IP or DNS records will be relatively the same speed.
There are several things you can look for on a website to help you figure out if the information is reliable. The first thing you should evaluate is the audience that the website is intended for. Is it intended for academics? School children? The general public?
The next thing you should look at is the author of the website. Is the author identified? Is the author an expert in their field? Can you establish the author's credibility? Is the author affiliated to an academic institution or credible organisation?
Look at the accuracy of the website. Check for spelling errors, proper grammar, and well-written text. Are there any sources cited? Are those sources credible?
You should also check to see when the information was published. Is the information up to date? Are all of the links up to date and functioning?
There is one last thing you can look at, and this is the domain of the website. Domains like .edu and .gov are more credible than .com or .net domains.
