what kind of network physical and logical networking topology do you have at home?
The majority of small-office and home networks have a physical bus topology. Peer to Peer and Client Server are two popular logical typologies.
The physical design of the network is referred to as physical topology. Logical topology describes how data will be transported and how the structure of network devices will be shown. Ring, Bus, Star, and Mesh are a few examples. For instance, Ring and Bus The "logical" component of a network architecture refers to the IP addressing method employed by the network.

Add an edge between two labeled vertices only if another edge of the same label doesn't exist?
Yes, you can add an edge between two labeled vertices only if another edge of the same label doesn't exist.
What is the vertices ?
A vertex, also known as a node, is a point in a graph that represents a relationship between two or more objects. A vertex may also be referred to as a corner, or a junction. In mathematics, a vertex is the point at which two or more curves, lines, or edges meet. In a graph, each vertex is associated with a set of edges, where an edge is a line or an arc that connects two vertices. Vertices can be used to represent data points, locations, and objects. For example, a vertex might represent the location of a city, the age of a person, or the cost of a product. Vertices can represent physical objects, such as buildings, and they can also represent abstract concepts, such as relationships or ideas.

By default, when a cell reference is first included in a formula (so that only the column and row reference are included), it is displayed as a relative cell reference.
When you enter a cell reference in a formula by default?Every cell reference is a relative reference by default. Based on the relative positioning of rows and columns, they alter when replicated across many cells. For instance, if you move the formula =A1+B1 from row 1 to row 2, it will change to =A2+B2. A cell reference is a relative reference by default, which implies that the reference is relative to where the cell is. To illustrate, if you refer to cell A2 from cell C2, you are actually referring to a cell two columns to the left (C minus A)—in the same row (2).By default, a cell reference is shown as a relative cell reference when it is first used in a calculation (such that only the column and row references are presented).To learn more about cell reference refer to:

Summation in mathematics is the addition of a series of any type of numbers, known as addends or summands; the result is their sum or total.
Other sorts of values, in addition to integers, can be summed: functions, vectors, matrices, polynomials, and, in general, elements of any form of mathematical object on which an operation marked "+" is specified.
Series are summations of infinite sequences. They are related to the idea of limit and are not addressed in this article.
A succession of adds is used to represent the summation of an explicit sequence. For example, the sum of [1, 2, 4, 2] is denoted 1 + 2 + 4 + 2 and yields 9, i.e. 1 + 2 + 4 + 2 = 9. Because addition is associative and commutative, no parentheses are required, and the result is the same regardless of the order of the summands.
The sum of a sequence containing only one element yields the element itself. By convention, summation of an empty sequence (a sequence with no items) yields 0.
The components of a series are frequently described by a regular pattern as a function of their location in the sequence. For basic patterns, summation of lengthy sequences can be represented by ellipses in most summands.

How programming practice takes place?It is seen as poor programming practice to save years as two digits, as was done in the Y2K bug, as this might result in ambiguity and data loss. Assuming that the decade 2000 would've been represented as "00" led to the Y2K problem, which could have led software to mistakenly read the year as 1900 rather than 2000.
It is advised to adopt a format that can accept diverse types of dates and times, such as the ISO 8601 standard, or to save years using four digits in order to prevent these types of problems.
