Computer security is basically divided into three main areas:
Vulnerability/threat assessment and risk management refers to a process that requires the identification, quantification and ranking of a system's possible vulnerabilities.
network intrusion detection and incident response refers to software that detects malicious activity or policy violations, and blocks them
digital forensic investigation refers to the process of identifying, recovering and interpreting (or validating) electronic data.
Generally a single individual may specialize in one of these areas, that is why he/she may need help with the others.
Computing source- Through the operating system, users can communicate with computers to perform various functions such as arithmetic calculations and other significant tasks.
Safeguard Of Data- There’s a lot of user data stored on the computer. Windows Defender in Microsoft Windows detects malicious and harmful files and removes them. Also, it secures your data by storing them with a bit to bit encryption.
Resource Sharing- Operating systems allow the sharing of data and useful information with other users via Printers, Modems, Players, and Fax Machines. Besides, a single user can share the same data with multiple users at the corresponding time via mails. Also, various apps, images, and media files can be transferred from PC to other devices with the help of an operating system.
Disadvantages-
Expensive- It is costly.
System Failure- System failures may occur. If the central operating system fails, it will affect the whole system, and the computer will not work. If the central system crashes, the whole communication will be halted, and there will be no further processing of data.
Virus Threats- Threats to the operating systems are higher as they are open to such virus attacks. Many users download malicious software packages on their system which halts the functioning of OS and slow it down.
Coding is a skill where you take instructions (the steps in a task) and translate it into a languaage.
Explanation:
Coding is a skill where you take instructions (the steps in a task) and translate it into a language the computer understands since computers do not communicate like humans. They communicate in a language called BINARY and
