When you write a program that will run in a GUI environment as opposed to a
command-line environment, some syntax is different.
Explanation:
- GUI (Graphical User Interface) which is the computer user interface uses graphical images to activate and run the applications.
- Command line interface is a interface that is in a text format, which can accept commands for a task.
- So, to program both interface, we need high level program skills with good understanding in programming languages like C++, C etc and algorithms.
- Here, the GUI syntax differs from the command line interface.
Answer:
A. True.
Explanation:
Authentication in computer technology can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
Digital certificates, smart cards, picture passwords, and biometrics are used to perform an authentication.
Hence, if the authenticator is encrypted with the sender's private key, it serves as a signature that verifies origin, content, and sequencing.
<em>This simply means that, when a user enters his or her private key (password); the authenticator matches the private key to the uniquely defined credentials. Permission and access is granted by the authorization system right after a successful authentication. </em>
Answer:
FALSE
Explanation:
In the design phase of SDLC we design the document which are used in the implementation phase. In this phase the SRS document is converted into the logical view structure that holds the whole specification.
Their are following points about Design phase of SDLC
- After the analysis phase the designing phase is implemented .
- In the beginning it does not need programming languages, development tools etc .
So the given statement which is mention in question is FALSE
Answer:
Yes there is a problem.
Explanation:
Yes there is a problem.
Looking at /22, the host part has 10 bits(right most 10 bits). The subnet mask is:
1111111.11111111.11111100.00000000
The first IP address which is 192.168.68.0 in binary form:
11000000.10101000.1000100.00000000
Here all the 10 bits of host part are 0's. Hence it is a valid network IP address.
192.168,68.0 - This is avalid subnet id
The Next IP address 192.168.69.0 in binary form:
11000000.10101000.1000101.00000000
Here all the 10 bits of host part are not 0's. Hence it is not a valid network IP address for /22 cidr.
Moreover this address lies in the first subnet - 192.168.68.0, which has host addresses in the range of 192.168.68.1 to 192.168.71.254
Hence other IP addresses 192.168.69.9/22, 192.168.70.0/22 and 192.168.71.0/22 lies n the subnet 192.168.68.0/22.
There are different ways to repair a computer. All computing devices do not have the same components and as such one must get the required part so that one can be able to repair the system.
<h3>What is the thing one should do to a computer problem with issues?</h3>
When you notice that a computer is having trouble with a piece of computer hardware, such as the monitor or keyboard, the first step to take is to check all the cables and when you notice they are not the the fault, you can then open the system.
Before opening the case of the system, you must first turn off the computer, identify the part with issues and repair or replace it.
