Why was the term personal computer created?

Computers and Technology
1 answer:
tresset_1 [31]3 years ago
3 0
It was created to show the difference between computers that were owned by companies (at one point they were so large and so expensive that only big groups could afford and store them), and the era when computers became small enough for individuals to be able to fit them in their own homes, and also afford them. The era of the Personal Computer (PC) was a huge changing point in history because it brought a lot of power and connectivity into people's homes that hadn't been available before.

What happens when the programmer tries to access an array cell whose index is greater than or equal to its logical size?
just olya [345]

Answer:

When a programmer tries to access an item in an array cell whose index is greater than or equal to the array's logical size, this data element or item is garbage. This means that currently, the item is not the part of the program's useful data. Garbage contains objects or data which will not be used by a program running on it. So the value returned could be either of the two:

  • Value would be an arbitrary or random number if it is an array of numbers. Arbitrary means that the value is not predefined or specified in advance.
  • Value returned would be null if it is an array of objects.

Consists of forging the return address on an email so that the message appears to come from someone other than the actual sender
Pavlova-9 [17]

Answer:

C. Spoofing.

Explanation:

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.

Spoofing can be defined as a type of cyber attack which typically involves the deceptive creation of packets from an unknown or false source (IP address), as though it is from a known and trusted source. Thus, spoofing is mainly used for the impersonation of computer systems on a network.

Basically, the computer of an attacker or a hacker assumes false internet address during a spoofing attack so as to gain an unauthorized access to a network.
