Answer:
System software is software on a computer that is designed to control and work with computer hardware. The two main types of system software are the operating system(Windows,Linux,Mac OS) and the software installed with the operating system, often called utility software (Anti virus, Disk formatting, Computer language translators) . In some cases, the operating system and utility software depend on each other to function properly.
Some system software is used directly by users and other system software works in the background. System software can allow users to interact directly with hardware functionality, like the Device Manager and many of the utilities found in the Control Panel.
It would either be A. Audio card or D. Sound card but most likely A
There are various kinds of network media and each one of them has different features and benefits. Some have different characteristics and not all of them are meant to perform the same purpose. While choosing network media, a number of criteria must be met. These criteria include:
The distance the selected medium can successfully carry a signal.
The environment where the selected medium is to be installed
Explanation:
The distance the selected medium can successfully carry a signal – The type of network media you choose depends on the distance it can cover before you install signal boosters or repeaters. Repeaters are used to regenerate signals that are required to cover greater distances. A UTP cable as compared to fiber is more prone to interference like noise and the distance it covers before a signal repeater is installed is shorter. Fiber cable is considered the best for distances as it can cover longer distances.
Environment should also be considered when choosing network media - If your network is setup in a place where there is too much electromagnetic field being generated, then you may be required to purchase fiber optic cables. Fiber optics are immune to such interference.

Answer: Its A. used to protect the transmission of software and large files to be downloaded
Explanation: Hashing is an algorithm that calculates a fixed-size bit string value from a file. A file basically contains blocks of data. Hashing transforms this data into a far shorter fixed-length value or key which represents the original string. The hash value can be considered the distilled summary of everything within that file. A good hashing algorithm would exhibit a property called the avalanche effect, where the resulting hash output would change significantly or entirely even when a single bit o...
