Explanation:
Answer: The goals of computer security are to protect computers and users from data theft or loss as well as damage to any part of the computer.
Explanation: Common means of achieving computer security are firewalls, anti-virus software and this can fail due to hardware problems or
weaknesses that prevent malicious attacks.
To answer this question, think of a time when you experienced any one of these. For example, personally, I was once an unfortunate victim of a general malicious attack that took advantage of a weakness in my anti-virus software. After clicking on a link on a dodgy website, a virus was installed on my computer. My computer finally crashed, without any hope of restarting it. I lost all my data and I had to buy a new computer. This was a malicious attack.
However, sometimes people can be specifically targeted to steal their data or monitor their activities.
Answer:
A compiler takes the program code (source code) and converts the source code to a machine language module (called an object file). Another specialized program, called a linker, combines this object file with other previously compiled object files (in particular run-time modules) to create an executable file. In short, it's A or D.
Answer:
All of the above.
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
Hence, the operating system (OS) provides utility software designed to perform specific tasks. Some of the tasks it performs are;
A. Establishing an Internet connection.
B. Coordinating tasks between programs.
C. Configuring peripheral devices.
D. Monitoring security.
