Answer: star
Explanation: A star network topology is an implementation of a spoke–hub distribution paradigm in computer networks. In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. The star network is one of the most common computer network topologies.
Answer:
Can be executed on multiple platforms.
Explanation:
A program is portable if it is not platform dependent. In other words, if the program is not tightly coupled to a particular platform, then it is said to be portable. Portable programs can run on multiple platforms without having to do much work. By platform, we essentially mean the operating system and hardware configuration of the machine's CPU.
Examples of portable programs are those written in;
i. Java
ii. C++
iii. C
A. use split worksheet view to break the worksheet into different visible sections
<u>Explanation:</u>
Jason is working on a project that requires him to manage a huge amount of data. There are numerous instances when a user has to manage a huge amount of data within a single spreadsheet. It will cause trouble for the user to simultaneously access the data from more than one table in the same sheet.
To deal with this problem, Jason can track and compare this data as he works on the spreadsheet by using the split worksheet view to break the worksheet into different visible sections. The different sections provide a better view of the tables and data extraction and manipulation become easy.
A method is written with the header 'num' yourMethod(string name, num code). The method's type is <u>'num'.</u>
In the context of programming. a header refers to supplemental data placed at the beginning of a block of data being transmitted or stored. In the context of the Java method, the header is where you tell the Java program what value type if any, the method will return (a string value, an int value, a double value, etc). As well as the return type, you require a name for your method, which is also placed in the header. You can pass values over to your methods in between a pair of round brackets.
