Which of the following network device connects a node to another node within LAN?

a) Switch
b) Gateway
c) Router
d) Modem

a) Switch

Explanation:

In Computer Networking, a node is the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.

Examples of network nodes are modem, hubs, computer, switches, phone and printers.

Multiple nodes are basically required to establish a network connection.

A switch is a network device that connects a node to another node within a Local Area Network (LAN) by using packet switching to receive and forward data to the intended destination device such as router.

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
