Correct Answer :   Flip Flop

---

In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information.A flip-flop stores a single bit (binary digit) of data; one of its two states represents a “one” and the other represents a “zero”. Such data storage can be used for storage of state, and such a circuit is described as sequential logic. When used in a finite state machine, the output and next state depend not only on its current input, but also on its current state.

Correct Answer :   Routing

---

In order to transfer packets from a sending host to the destination host, the network layer must determine the path that the packets are to follow. Routing is the process by which systems decide where to send a packet. It directs network packets from their source toward their destination through intermediate network nodes by specific packet forwarding mechanisms.

Correct Answer :   Excess 3-Code

---

The weighted codes are those that obey the position weighting principle, which states that the position of each number represent a specific weight. In weighted codes, each digit is assigned a specific weight according to its position. Non-weighted or un-weighted codes are those codes in which the digit value does not depend upon their position i.e., each digit position within the number is not assigned fixed value. Examples of non-weighted codes are: Un-weighted BCD code, Excess-3 code and gray code.

Correct Answer :   Human brain

---

Wetware is a term drawn from the computer-related idea of hardware or software, but applied to biological life forms. Here the prefix “wet” is a reference to the water found in living creatures. Wetware is used to describe the elements equivalent to hardware and software found in a person, namely the central nervous system (CNS) and the human brain.

Correct Answer :   Write – back

---

The write-back method involves updating only the cache location and to mark it as updated with an associated flag bit, often called the dirty or modified bit. The main memory location of the word is updated later, when the block containing this marked word is to be removed from the cache to make room for a new block. The reason for the write back method is that during the time a word resides in the cache, it may be updated several times.

Correct Answer :   Wired Equivalent Privacy

---

WEP stands for Wired Equivalent Privacy. It is a security algorithm for IEEE 802.11 wireless networks. Introduced as part of the original 802.11 standards ratified in 1997, its intention was to provide data confidentiality comparable to that of a traditional wired network. It was superseded by Wi-Fi Protected Access (WPA) in 2003.

Correct Answer :   Protocol

---

In information technology, a protocol is an agreement between the communicating parties on how communication is to proceed. Violating the protocol makes communication more difficult, if not impossible. A protocol is the specialist set of rules that end points in a telecommunication connection.

Correct Answer :   Integrated circuit

---

IC stands for Integrated Circuit. It is a set of electronic circuits on one small plate (“chip”) of semiconductor material, normally silicon. Also known as chip or microchip, ICs are the heart and brains of most circuits and are are a keystone of modern electronics.

Correct Answer :   Cache

---

The memory buffer used to accommodate a speed differential is called cache. It is a hardware or software component that stores data so future requests for that data can be served faster. Cache serves to add fast memory between the CPU and main memory.
