a)
The operating system (OS)
b)
Allowing Internet Browsing

Allowing Internet Browsing
b)
Hertz (Hz)
c)
Operating systems controls and manages the computer system. Utility programs perform extra functionality and housekeeping tasks that keep computers running efficiently. Operating systems come bundled with additional utility software, which helps to keep them working well. They are often packaged as part of the computing system. Some utility systems are often packaged as Antivirus Software, are bought as stand-alone software programs.
d)
It is software that provides a platform for other software to work, which includes operating systems and utility programs.
89.
Give examples of utility software

c)
Storage where devices are not constantly connected to the computer. Devices which are not directly accessible by the computer's CPU and often used for long-term storage of programs and data.
d)
It will be supplied with a driver which you need to install.
90.
Memory Management: To run a program, the computer must copy the program from storage into main memory
a)
Data used by the program is copied into main memory. The operating system keeps a record of where each program and its data are located. The operating system will make sure not to overwrite existing programs and data.
b)
(non-volatile) permanent.
c)
The brain of the CPU
d)
It prevents malware being installed and important files being changed or deleted.
91.
What does an antivirus do?
a)
Taking inputs from users. Outputting information to users. Storing Information.
b)
Allows the CPU to process more data during the same time period.
c)
It means more applications or memory intensive applications can run smoothly.
d)
It prevents malware being installed and important files being changed or deleted.
92.
What does Disk Formatting do?
a)
The CPU takes a chunk of data/instructions from the RAM and keeps it close so that it always has a constant supply of data to process.
