A(n) _________________________ is a computer or special hardware device that provides interconnection between company networks, home networks, and institutional networks.
A network router is a computer or special hardware device that provides interconnection between company networks, home networks, and institutional networks.
Routers are responsible for directing network traffic to its destination based on network addresses. They serve as the central point for interconnecting multiple networks and creating a single, logical network for data communication.
Routers operate at layer 3 of the OSI model and use routing tables to determine the best path for forwarding data packets between networks. They examine the IP addresses of incoming packets and compare them against their routing table to identify the appropriate outgoing interface.
Routers also provide other network services, such as network address translation (NAT), firewall protection, and virtual private network (VPN) connectivity.
Routers come in various sizes and types, ranging from small home routers to large enterprise-grade routers used by Internet service providers (ISPs). They can be used to connect LANs (Local Area Networks), WANs (Wide Area Networks), and the Internet. Some routers are also designed for specific purposes, such as wireless routers for creating wireless networks and core routers for high-speed data transport in large networks.

An SQL query is a command written in the Structured Query Language (SQL) that is used to retrieve, manipulate, and manage data stored in a relational database. It can be used to search for specific data, update records, or create new tables and relationships.
1. The query optimizer needs to know the sizes of the tables and indexes, selectivity of the predicates, and the available join algorithms to select a good query execution plan for the given query.
2. There are two different join orders that a System R style query optimizer considers when processing the given query:
- (Suppliers S) -> (Supply Y) -> (Parts P)
- (Parts P) -> (Supply Y) -> (Suppliers S)
3. Indexes on the sid attribute in the Suppliers table and the pid attribute in the Parts table might be of help in processing this query as they are used in the join conditions.
4. Adding DISTINCT to the SELECT clause may affect the plans produced by eliminating duplicate rows from the result set. The optimizer may need to use additional operations to remove duplicates, which may increase the query processing time.
5. Adding ORDER BY sname to the query may affect the plans produced by adding a sort operation to the execution plan, which may increase the query processing time.
6. Adding GROUP BY sname to the query may affect the plans produced by adding a group by operation to the execution plan, which may increase the query processing time.
