An optical mark reader (OMR) also known as optical mark recognization is an input device used to scan and read marks made by pencil or pen. It consists of a scanner that scans a filled form to detect which option is marked.

OMRs are used in applications such as multiple-choice tests, surveys, voting systems, and other areas where users make distinct marks on the form. It has the advantage of being a more accurate and fast method of data entry. However, they are only suitable for data that have multiple choices, and the accuracy depends on how the user marks the document.

Computer networks can be implemented using peer-to-peer and client-server architecture depending on the user requirement. The main difference between peer-to-peer and client-server is that in the client-server we have one computer that supervises and serves other computers with the requests. While on peer-to-peer no computer acts as a supervisor but they work on the same level both as servers and clients.

The client-server model is the most common network that is deployed in most organizations today since it offers more flexibility and has a central control point.
