Answer:
Modern (i.e 386 and beyond) x86 processors have eight 32-bit general purpose registers, as depicted in Figure 1. The register names are mostly historical. For example, EAX used to be called the accumulator since it was used by a number of arithmetic operations, and ECX was known as the counter since it was used to hold a loop index. Whereas most of the registers have lost their special purposes in the modern instruction set, by convention, two are reserved for special purposes — the stack pointer (ESP) and the base pointer (EBP).
For the EAX, EBX, ECX, and EDX registers, subsections may be used. For example, the least significant 2 bytes of EAX can be treated as a 16-bit register called AX. The least significant byte of AX can be used as a single 8-bit register called AL, while the most significant byte of AX can be used as a single 8-bit register called AH. These names refer to the same physical register. When a two-byte quantity is placed into DX, the update affects the value of DH, DL, and EDX. These sub-registers are mainly hold-overs from older, 16-bit versions of the instruction set. However, they are sometimes convenient when dealing with data that are smaller than 32-bits (e.g. 1-byte ASCII characters).
When referring to registers in assembly language, the names are not case-sensitive. For example, the names EAX and eax refer to the same register.

Answer:
A. Request timeout.
Explanation:
The end devices like the computer systems in a network seeks to share resources with one another and/ or request resources from central server.
With this, there are two ways computers in a network can communicate. They are peer to peer network communication and client-server network communication.
The client-server communication requires a dedicated central server where computers in the network require data. Peer to peer describes a network where computers serve as both client and server to each other.
Request timeout is a message sent to a source when the time to live period (TTL) of a packet expires.
