A. 243
B. True
C. 0
Explanation:
Macro instruction is a line of coding used in computer programming. The line coding results in one or more coding in computer program and sets variable for using other statements. Macros allows to reuse code. Macro has two parts beginning and end. After the execution of statement of quiz4 x, 4 the macro x will contain 243. When the macro is invoked the statement will result in an error. When the macro codes are executed the edx will contain 0. Edx serve as a macro assembler.
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.

An i/o system call returns one-bit information about the call's status, Therefore the given statement is true.
<h3>What is an i/o system?</h3>
- I/O (Input/Output) is a type of data processing system that sends and receives data from a computer hardware component, device, or network. A network allows data to be sent between devices. Computers would be unable to communicate with other systems or devices if I/O was not present.
- The primary function of an i/o system is processor communication, which includes a variety of tasks such as data transfer between the processor and an I/O module, accepting and decoding commands sent by the processor, reporting current status, and the ability for the I/O module to recognize its own unique address.
- A system call allows a user program to communicate with the operating system. The program requests a number of services, and the operating system responds by invoking a series of system calls to fulfill the request.
