Some key differences between a Serial and Parallel Adder are that a Serial Adder is slower, a Parallel adder is a combinational circuit and the time required for addition depends on the number of bits in a Serial, but not a Parallel. A Serial Adder is a sequential circuit while a Parallel is a combinational circuit.
SERIAL AND PARALLEL COMUNICATION MEANS THE METHOD USED FOR COMMUNICATION.IN SERIAL COMMUNICATION THE DATA THAT IS TO BE COMMUNICATED IS PASSED SERIALLY THAT IS ONE BY ONE.IN PARALLEL COMUNICATION THE DATAS ARE PASSED PARALLEL.

The answer is either. Computer networking is a very broad category encompassing an astonishingly wide range of communication technologies. When Voyager made it's last transmission from the depths of space to earth, this could be considered computer networking (albeit with rather high latency) in that two computers were involved, one on each end of the signal and that one or more protocols understood by both computers were used.Today, whether using WiFi, a LAN, a MAN or WAN etc. and whether the computers are connected by buried Fiber Optic cable or communicate via directional microwave antennas or any other electronic methodology, the basic technique (not the technology) is the same. Two computers must be able to communicate with each other in order to network. This communication MAY be serial or it MAY be parallel. Most frequently it is serial today.Consider that a fiber optic cable can be in only one state at a time, either dark or illuminated (0 or 1). This communication is necessarily serial, but the high speed of light and the frequency at which switching from dark to lighted states is possible makes it incredibly fast. Likewise, if two fiber optic cables were used, connected to the same NICs (Network Interface Cards) theoretically, it would be possible to support parallel fiber optic communication directly from PC to PC.

It means an 8 bit parallel I/O interface, as opposed to 8251 which is a serial I/O.
No. PS/2 is a low speed serial connection. The lowest port used for a webcam that I am aware of is a a parallel port.

A zero-slot LAN is a local-area network (LAN) that uses existing serial and/or parallel communication ports on the computers in the network instead of requiring network interface cards (NICs) that would occupy an expansion slot. Advantages It leads to transmitting between computers over a serial or parallel port, thus freeing up an expansion slot normally used by LAN cards (NICs). Disadvantages Zero-slot LANs are typically slower than LANS that use NICs and are limited to two or three network nodes.
big advantage of parallel transmission is the factor of speed. All else being equal, parallel transmission can increase the transfer speed by a factor of n over a serial transmission. But there is also a very significant disadvantage of parallel transmission. And that is the factor of cost. It can be proved from the fact that the parallel transmission requires 'n'

Serial communication is preferred over parallel communication for long-distance WAN links primarily due to reduced crosstalk and electromagnetic interference. In parallel communication, multiple wires transmit data simultaneously, increasing the risk of signal degradation over long distances. Serial communication, using a single wire or pair, minimizes these issues and simplifies the design and implementation, allowing for higher data rates and longer transmission distances without significant loss of integrity. Additionally, serial connections require fewer physical resources, making them more cost-effective for WAN applications.
Parallel data transmission is faster compared to serial data transmission. The speed of a parallel link is equal to the number of bits sent multiplied by the bit rate of each individual path.
A serial wire can be used for several uses. Mainly, it's used for basic communication between different devices. The main advantage is the fact that serial communication can use only three wires. Parallel requires several more, typically eight, or sixteen, plus signalling, and traditionally is faster. But for simple communication between devices, which could be computers or other devices, serial communication can simplify things. Serial communication can also be used for great distances. The telegraph was serial communication. Hence "AT&T"!
Neither. A computer case is just a box to hold the parts of a computer. It provides no form of communication itself.
Depends, is the device serial or parallel?
Can span longer distance, fewer data paths, flexibility in design, error detection,
