The program is an illustration of file manipulations, where files are accessed, read and modified

<h3>The main program</h3>

The program written in Python, where comments are used to explain each action is as follows;

#This gets the file name

fname = input("Enter file name: ")

#This gets an integer value

num = int(input("Integer: "))

#This opens the file

file = open(fname, 'r')

#This initializes the number of characters to 0

count = 0

#This begins an iteration

while 1:

# This prints each character

print(file.read(1))

#This increases the number of characters printed by 1

count+=1

#When 10 characters are printed

if count == 10:

    #This closes the iteration

 break

#This closes the file

file.close()

<h3>What is OSI Model?</h3>

The OSI Model is known to be a kind of a logical and conceptual framework that tells all about network communication that is often used by systems in an open to interconnection and also in any communication with other forms of systems.

Note that the Open System Interconnection (OSI Model) is one that tells more about a logical network and it is one that also tells about computer packet transfer via the use of various layers of protocols.

Therefore, The protocols  that are often used in each layers in each OSI reference model are:

Layers                           Protocols

Layer 7- Application          SMTP, HTTP, FTP, POP3, SNMP

Layer 6- Presentation            MPEG, ASCH, SSL, TLS

The SQL WHERE clause: Limits the row data that are returned. Limits the column data that are returned. ALL Limits the column and
enyata [817]

Answer: Limits the row data that are returned.

Explanation: In structured query language (SQL), The where clause is used as a filter. The filter is applied to a column and as such the filter value or criteria determines the values that are spared in the column on which the WHERE clause is applied. All rows in which the column value does not meet the WHERE clause criteria are exempted from the output. This will hence limit the number of rows which our command displays.

For instance,

FROM * SELECT table_name WHERE username = 'fichoh' ;

The command above filters the username column for username with fichoh, then displays only rows of Data with fichoh as the username. All data columns are displayed but rows of data which do not match fichoh are exempted.
