Answer:
a. A numeric keypad.
b. An interpreter.
c. A 3D printer.
d. A speaker.
Explanation:
An output device can be defined as a hardware device that typically receives processed data from the central processing unit (CPU) and converts these data into information that can be used by the end user of a computer system.
Also, an input device can be defined as any device that is typically used for sending data to a computer system.
Generally, all of the output and input device of a computer are known as peripheral (external) devices and they provide data (informations) to the end users in various formats such as video, audio, texts, images etc.
Since output and input devices are peripheral (external) devices, they can be connected to the computer system wirelessly or through a wired-connection (cable).
Some examples of peripheral (external) devices are monitor, speakers, keyboard, printer, mouse, scanner, projector etc.
Basically, the three (3) key element of a computer system are: a set of memory modules, processor and a set of input-output (I/O) modules. Each of the input-output (I/O) module interfaces to the central switch or system bus and are used to control one or more peripheral (external) devices.
a. A numeric keypad is a device used to input a PIN. It comprises of numbers ranging from 0 to 9.
b. An interpreter analyses and executes a program line by line.
c. A 3D printer produces output in the form of solid objects. It is typically used for inscribing or printing textual informations or graphic images on an object in three dimensions.
d. A speaker produces output in the form of sound. It is an electronic device that converts electrical signals into sound energy (waves).

how to learn python ?
Answers
Answer:
See below.
Explanation:
To learn python programming language, first, you have to know the basic. Surely, you may recognize this function namely print()
print(“Hello, World!”) — output as Hello, World!
First, start with familiarizing yourself with basic function such as print. Then step up with arithmetic and declare or assign variable then list.
Here are example of functions:
1.) print(argument) — If argument is a string (word-typed), make sure to use “” or ‘’ or else it’ll output an error and say the argument is not defined.
print(“Hi, Brainly”) will output Hi, Brainly
print(2+3) will output 5
Numerical data or numbers do not necessarily require “ “ or ‘ ‘
print(3+3) will output 6 but print(“3+3”) will output 3+3 which is now a string.
2.) type(argument) - this tells you which data/argument it is. There are
< class ‘str’ > which is string, meaning it contains “ “ or ‘ ‘< class ‘int’ > which is integer< class ‘float’ > which is decimal (20.0 is also considered as float, basically anything that contains decimal is all float type)< class ‘list’ > which is a list. List is something that contains elements within square brackets [ ]etc.
Make sure you also do print(type(argument)) as well so it will print out the output.
3.) Arithmetic
+ is additionEx. print(1+3) will output 4
2. - is subtraction
Ex. print(5-4) will output 1
3. * is multiply
Ex. print(4*5) will output 20
4. ** is exponent
Ex. print(5**2) will output 25
5. / is division
Ex. print(6/3) will output 2 — sometimes will output the float type 2.0
6. % is modulo or remainder
Ex. print(7%2) will output 1
4.) Variables
To assign a variable, use =
An example is:
x = 2
y = 5
print(x+y) will output 7
print(type(x)) will output the < class ‘int’ >
These are examples of what you’ll learn in basic of python - remember, programming depends on experience and always focus on it. Keep practicing and searching will improve your skill at python.
An administrator wants to restrict access to a particular database based upon a stringent set of requirements. The organization is using a discretionary access control model. The database cannot be written to during a specified period when transactions are being reconciled. What type of restriction might the administrator impose on access to the database
Answers
Answer:
Time of the day and object restrictions
Explanation:
From the question, we understand that the database is not allowed to be accessed at a certain period of time.
Because this has to do with time (period), the administrator will need to set a time of the day object restriction on the database in order to prevent the users from accessing the database objects
See the lseek_example.c file. Modify the lseek_example.c, such that it reads from an input file (named "start.txt") and will print to an output file (named "end.txt") every (1+3*i)th character, starting from the 1st character in the input file. In other words, it will print the 1st character, then skip 2 characters and print the 4th one, then skip 2 characters and print the 7th one, and so on.
For instance, for input file:
ABCDEFGHIJKLM
It will output:
ADGJM
Iseek_example.c file contant:
// C program to read nth byte of a file and
// copy it to another file using lseek
#include
#include
#include
#include
void func(char arr[], int n)
{
// Open the file for READ only.
int f_read = open("start.txt", O_RDONLY);
// Open the file for WRITE and READ only.
int f_write = open("end.txt", O_WRONLY);
int count = 0;
while (read(f_read, arr, 1))
{
// to write the 1st byte of the input file in
// the output file
if (count < n)
{
// SEEK_CUR specifies that
// the offset provided is relative to the
// current file position
lseek (f_read, n, SEEK_CUR);
write (f_write, arr, 1);
count = n;
}
// After the nth byte (now taking the alternate
// nth byte)
else
{
count = (2*n);
lseek(f_read, count, SEEK_CUR);
write(f_write, arr, 1);
}
}
close(f_write);
close(f_read);
}
// Driver code
int main()
{
char arr[100];
int n;
n = 5;
// Calling for the function
func(arr, n);
return 0;
}
