Answer:
Program
Explanation:
Program is like a set of instructions that helps hardware process data into information.
Every hardware needs a program to process data into information.
For example take the example of a data processing software like MS Excel.
You open a spreadsheet and enter some data into your sheet. and then ask the program to do some calculations with this data and give you output results. The spreadsheet software does this processing in the background for you and provides you the results.
Without program a hardware doesn't know what to do with the data. Therefore, a program is like a instruction set that guides the hardware what to do with the data.
Note: The terms software and program are usually used together but there is a difference between software and program
A software is a generalized term and program is more like a specific term.
software can be made up of several different programs which performs many different tasks. On the other hand, a program only carry out a specific task or set of instructions.
Answer:
True.
Explanation:
A proxy server, for example, can hide the true origin of a request, thus, keeping your IP address private, and non-visible to the internet. However, this won't necessarily keep malicious attackers from reaching your network. A proxy simply acts as an intermediary between you, and the server you are trying to reach.
Firewalls or an Intrusion Detection Systems (IDS) are pieces of software specifically designed to keep attackers out of your system, they can analyze the web traffic and detect malware, or they can prevent the delivery of some packages, based on its content if the IDS consider it's malicious.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The iteration variable begins counting with 0 or 1.
As you know the iteration mostly done in the looping. For example, for loop and foreach loop and while loop, etc.
It depends upon you that from where you can begin the counting. You can begin counting either from zero or from one.
For example: this program counts 0 to 9.
<em>int total=0;</em>
<em>for(int i=0; i>10;i++)</em>
<em>{</em>
<em>total = total+i;</em>
<em>}</em>
Let's suppose, if you want to begin counting from 1, then the loop should look like below:
<em>int total=0;</em>
<em>for(int i=1; i>10;i++)</em>
<em>{</em>
<em>total = total+i;</em>
<em>}</em>
<span>Horizontal scaling of client/server architecture means that more machines or more client workstation are added in the network. The impact on the network should be small and negligible.
Vertical scaling on the other hand means that more power (processing units) are added in the network. </span>
Answer:
The value of sum is 66
Explanation:
i = 1
sum = 0
while (i <= 11) {
sum = sum + i;
i++;
}
i = 1
- sum = sum + i
- sum = 0 + 1
- sum = 1
i = 2
i = 3
i = 4
i = 5
i = 6
i = 7
i = 8
i = 9
i = 10
i = 11
i = 12 --> does not comply with the condition "i < = 11", the while loop is over
