Answer:
Composite primary key, or simply, composite key
Explanation:
When multiple fields (columns of a table) are combined to form a primary key, the resulting key is called a composite key.
Hope this helps!
guess you better read the directions and just read the book yourself and find the answer.
Answer:
The technician has made a cross-over cable.
Explanation:
The network is a platform that provides two or more computers to communicate. There different types of networks, namely, local-area network (LAN), wide-area network (WAN), MAN or metropolitan-area network etc.
Devices in a network can be connected with cables (ethernet IEEE 802.3) or wirelessly (wifi IEEE 802.11a/n/g). Wiring standards are strictly followed in ethernet configuration.
Two ethernet wiring standards are T568A and T568B. The difference in both standards are the pin configuration and their position in a wire defines a cable system.
When a T568A or T568B are used on both ends of a twisted pair cable, it is called a straight-through cable. When T568A is used on one end and T568B on the other, it is called a cross-over cable.
These cable systems are used for different applications. the straight-through cable is used for connecting devices that are not the same like router to switch, switch to computer etc. The cross-over cable connects similar network devices like router to router, switch to switch etc.
Answer:
true
Explanation:
Mainly true, but partly false. There are two bits in a computer that supply speed: The processor (measured in hertz eg. 2Ghz Processor) and RAM (bits and bytes eg 2GB of RAM). The processor is more to do with the speed programs run and load at, and RAM let's you use lots of memory intensive programs at the same time, although this also comes down to the processor and vice versa.

FDE stands for full disk encryption. FDE encrypts data as it is written to the disk and decrypt data as it is read off the disk. It is the simplest method of deploying encryption
,transparent to applications, databases, and users.
A hard drive that uses FDE is often referred to as a self-encrypting hard drive. correct answer: B
