- 1CPU (Central Processing Unit)Fetches, decodes and executes data
- 2What is RAMRAM is a volatile which mean that the data is not stored when the computer is switched off
Stores the programes parts of the operating system and the files currently being used - 3What is MalwareSoftware which is specifically designed to disrupt, damage, or gain authorized access to a computer system
- 4What is PhishingThe fraudulent practice of sending emails purporting to be from reputable companies in order to induce individuals to reveal personal information, such as passwords and credit card numbers.
- 5What is Clock speedClock speed is the number of fetch decode execute cycles a CPU can perform per second. This is measured in hertz (Hz)
1 Hz - 1 cycle per second
1KHz - 1000 cycles per second
1MHz - 1 million cycles per second
1GHz - 1 billion cycles per second - 6Hard DriveStores all the programs, operating system and files needed for the computer system to run
Non - volatile - Data is stored when the computer is switched off - 7Social EngineeringSocial engineering is an attack vector that relies heavily on human interaction and often involves tricking people into breaking normal security procedures.
- 8What is ScarewareScareware involves tricking the victim into thinking his computer is infected with malware or has inadvertently downloaded illegal content.
- 9CoresThe number of independent processors in the CPU which run the fetch decode execute cycle simutaneously.
Dual core : 2 independent processors
Quad core : 4 independent processors - 10Secondary storageNon volatile storage needed in a computer system to store programs, operating system or files.
- 11Pen testingPenetration testing (pen testing) is the practice of testing a computer system, network or Web application to find vulnerabilities that an attacker could exploit.
- 12What is EncryptionThe process of converting information or data into a code, especially to prevent unauthorized access.
- 13FirewallProtect a network or system from unauthorized access with a firewall.
