VPESR is an acronym (a word composed of the first letters of a phrase) that stands for Valence Shell Electron Pair Repulsion.

It's a scientific theory in the field of chemisty, and it predicts the shape of a molecule based on what atoms form this molecule.

If you want to understand the meaning of the name, you can devide it into

Valence shell electron
-electrons that are on the "outside" of the atom and can form bonds with other atoms

and it's the repulsion of these electrons that is being predicted.

Define a function in Scheme (or relation in Prolog) that checks whether a set of elements (represented as a list) is a subset of

mafiozo [28]

Answer:

subset([],[]).

subset([X|L],[X|S]) :-

subset(L,S).

subset(L, [_|S]) :-

subset(L,S).

Success:

subset([1,3], [1,2,3]).

subset(X, [1,3,4]). % error handling to compare sets in a given order

Fail:

subset([2,1], [1,2,3]). % compares in a different order from the first.

Explanation:

The function "Subset" in the source code above accepts two sets, then checks if the first set is a subset of the second. The code returns true if the condition is met.

What type of Windows server has Active Directory installed and is responsible for allowing client computers access to domain res

Basile [38]

Answer:

Domain controller

Explanation:

A domain controllers is a server which acknowledges authentication requests and validates users access on the computer network in order to use the resources.
This is done by the domain controller by verifying the username and password.
It also allows user to access the other domain and also access the resources of other domain.
For example there is a network of multiple computers and each computer requires authentication i.e user is asked to provide the username and password.
Authenticating every computer and managing is not easy so a computer is appointed this task of authentication other computers.
This computer is called domain controller which can easily maintain these authentication details of the users.
The authentication information (login details) of users, computers and shared resources is saved in Active Directory database.
If a user requests access to the resource via login then the login details (username and password) of the user should match with that stored in the Active Directory in order to grant access to the user.
Domain controller enables resources sharing and is good for large networks and provides with improved security.

What in the LAN for a small office, some user devices connect to the LAN using a cable, while others connect using wireless tech

dem82 [27]

Answer:

The ethernet protocol IEEE 802.3 is only meant for cable networks.

Explanation:

In this scenario, there are two types of networks, namely;

LAN and WLAN.

A LAN (local area network) is a network within a small area like a building, i which its workstation are connected using cables. The cabled network instantly use a protocol called Ethernet also known as IEEE 802.3.

WLAN (wireless local area network) is a small area network just like the LAN, but the difference is that its workstation are connected wireless (without cable). wireless networks uses wifi or 802.11a/n/g to connect to the network.

So, the ethernet protocol represents the cabled network, Wifi represents the wireless network.
