The biggest limitation of a network operating system (NOS) is _____ in terms of memory, process, device, and file management.

Answers

Answer 1

Answer:

Lack of global control.

Explanation:

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

There are different types of operating systems (OS) used for specific purposes and these are;

1. Batch Operating System.

2. Multitasking/Time Sharing OS.

3. Multiprocessing OS.

4. Single User OS.

5. Mobile OS.

6. Real Time OS .

7. Distributed OS.

8. Network OS.

A network operating system (NOS) can be defined as specialized computer operating system that are designed primarily for use on network devices such as routers, switches, workstations, which are mainly connected to a local area network.

Generally, the biggest limitation of a network operating system (NOS) is lack of global in terms of memory, process, device, and file management.

You have configured a LAN with 25 workstations, three network printers, and two servers. The workstations and printers will have dynamically assigned IP addresses, and the printers always need to have the same IP address assigned. The servers will have static IP addresses. What should you install on one of the servers, and what are some of the configuration options

Answers

Answer:

install and configure on the server DHCP (Dynamic Host Configuration Protocol)

Explanation:

In this scenario, you should install and configure on the server DHCP (Dynamic Host Configuration Protocol), this protocol automatically assigns each individual PC a unique IP address and DNS server information. This protocol has various configuration options such as being able to set a range for the IP addresses so that they can be used by different devices in the system. It also allows you to directly set the subnet and passage gateway so that all of the workstations can quickly communicate with one another and quickly be targeted by the administration.

The given SQL creates a Movie table and inserts some movies.

Run your solution and verify the result table shows just the titles and release dates for The Dark Knight and Crazy Rich Asians. 3 6 1 CREATE TABLE Movie ( 2 ID INT AUTO_INCREMENT, Title VARCHAR(100), 4 Rating CHAR(5) CHECK (Rating IN ('G', 'PG', 'PG-13', 'R')), 5 ReleaseDate DATE, PRIMARY KEY (ID) 7); 8 9 INSERT INTO Movie (Title, Rating, ReleaseDate) VALUES 19 ('Casablanca', 'PG', '1943-01-23'), 11 ("Bridget Jones's Diary', 'PG-13', '2001-04-13'), 12 ('The Dark Knight', 'PG-13', '2008-07-18'), 13 ("Hidden Figures', 'PG', '2017-01-06'), 14 ('Toy Story', 'G', '1995-11-22'), 15 ("Rocky', 'PG', '1976-11-21'), 16 ('Crazy Rich Asians', 'PG-13', '2018-08-15'); 17 18 -- Modify the SELECT statement: 19 SELECT * 20 FROM Movie 21 WHERE ReleaseDate < '2000-01-01'; 22

Answers

Answer:

The modified SQL code is as follows:

SELECT Title, ReleaseDate FROM movie WHERE Rating = "PG-13" and ReleaseDate >  '2008-02-01'

Explanation:

The syntax of an SQL select statement is:

SELECT c1, c2, c...n FROM table WHERE condition-1, AND/OR condition-n

In this query, we are to select only the title and the release date.

So, we have:

SELECT Title, ReleaseDate

The table name is Movie.

So, we have:

SELECT Title, ReleaseDate FROM movie

And the condition for selection is that:

Ratings must be PG-13

And the date must be later than February 1, 2008

This implies that:

Rating = "PG-13"

ReleaseDate >  '2008-02-01'

So, the complete query is:

SELECT Title, ReleaseDate FROM movie WHERE Rating = "PG-13" and ReleaseDate >  '2008-02-01'

What rules should the technician add to the firewall to allow this connectivity for the client workstations

Answers

Answer:

Explanation:

Based on the information provided in the question, the best rules that the technician should add to the firewall would be the following

Permit 10.10.10.0/24 0.0.0.0 -p tcp --dport 443

Permit 10.10.10.0/24 192.168.1.15/24 -p udp --dport 53

This is because port 443 is used for "Secure webs services" while UDP port 53 is used for queries and domain name resolution. Both of which are the main configurations that the security technician needs to obtain.

why the internet is not considered a mass medium in Africa​

Answers

I think the term “media” as used and understood by most people has more to do with content than with the means of disseminating said content.

“Mass media,” therefore, would be that content created by a few and copied to the many — a large circulation newspaper, for example, or a network television or radio program.

The internet’s content is anything but “mass” in that regard — there is mass media content on it, to be sure, but there is also a panoply of content created by many for dissemination to many — or the few who are attracted by the content created by a certain few, or a certain individual. The reasons why there is not an internet infrastructure like in other regions is because in Africa people have low levels of computer literacy, there is poor infrastructures in power supply and urbanism in general, and Internet services are offered only at a high cost. Hope this helps!

Answer:

the reason why internet not considered as a mass medium is probably because most of the African are not educated and civilized, thereby making them not common to the usage of the internet.

List to String (0.5 points) Since we are often dealing with a list of strings, it would be useful to have a function to tum a list of strings back into one single concatenated string, This function will return a string that is each element of input_list concatenated together with each separated by the string Separator For example, the following function call: list_to_string('This', 'is's 'fun' should return; "This is fun To do this, write a function called list_to_string This function should have the following inputs, outputs, and internal procedures: Input(s) input_list - list of strings . separator - string Output(s); . output - string Procedure(s): - assign a variable called output to be the first (index 0) element from input_list - loop through the rest of input_list, looping from the 2nd element index 1) through to the end of the list - Within the loop, use string concatenator to combine output with the current element, separated by separator • Assign the output of this to be the new value of output • return output, which should now be a list of the elements of input_list joined together into a single string

Answers

Answer:

The function is as follows:

def list_to_string(input_list,separator):

   output = ""

   for inp in input_list:

       output+=inp+separator

       

   output = output[:-1]

   return output

Explanation:

Given

See attachment for instruction

Required

A function to convert list to string

This defines the string

def list_to_string(input_list,separator):

This initializes the output to an empty string

   output = ""

This iterates through the input list

   for inp in input_list:

This concatenates every string in the list including the separator

       output+=inp+separator

This removes the last character of the string

   output = output[:-1]

This returns the output string

   return output

If it is inside the Rectangle then the method returns true otherwise it returns false.
