You may need a "return" for the signal. If you do not the other wire is twisted in various configurations along the length to reduce crosstalk and signal leakage.

It is easier to balance capacitive loads,

No. Frame Relay is not operating at Layer 3. Frame Relay is strictly a Layer 2 protocol suite, whereas X.25 provides services at Layer 3 (the network layer) as well. This enables Frame Relay to offer higher performance and greater transmission efficiency.

IP Source Guard is functionality of ethernet switches introduced by Cisco company. This functionality allows to block unwanted network traffic form IP addresses which were not assigned by trusted DHCP server. IP source guard requires DHCP snooping functionality of the switch which protects the network against unauthorized DHCP servers connected to the networg by mistake or with malicious intentions. DHCP snooping feature builds the IP database which holds information about ethernet port, mac address and IP address assigned to end point computer.

It depends, which operating system you are going to install, usually windows occupies more space than that of Linux operating systems. Windows can utilize upto 5GB space for all the installation files, whereas Linux eats much low space.

No - RJ45 plugs need to be crimped, RJ45 Sockets need the wires connecting using a punchdown tool which pushes the insulated wires between the contacts and often trims the surplus wire at the same time. A better explanation is here:

If you are in an absolute pinch and can't get to the store to buy crimping pliers and you have a lot of cable and cable ends upon which to practice and sufficient patience, you may be lucky enough to produce a usable cable. Don't forget to punch down the plastic strain relief that hinges perpendicular to the plug's axis on the underside.

A Local user account is a user account that is part of the domain or work group.

to convert decimal to binary, repeatedly divide the value by 2, taking the remainder until the value is 1 or 0.

1987 / 2 = 993 r 1

993 / 2 = 496 r 1

496 / 2 = 248 r 0

248 / 2 = 124 r 0

124 / 2 = 62 r 0

62 / 2 = 31 r 0

31 / 2 = 15 r 1

15 / 2 = 7 r 1

7 / 2 = 3 r 1

3 / 2 = 1 r 1

1 / 1 = 1

Thus: 1987 in binary is 11111000011.

Proof (binary back to decimal):

1 * 2^0 = 1

1 * 2^1 = 2

0 * 2^2 = 0

0 * 2^3 = 0

0 * 2^4 = 0

0 * 2^5 = 0

1 * 2^6 = 64

1 * 2^7 = 128

1 * 2^8 = 256

1 * 2^9 = 512

1 * 2^10 = 1024

1024 + 512 + 256 + 128 + 64 + 2 + 1 = 1987

To convert to octal, split the binary value into groups of 3 bits:

11 111 000 011

Pad the first group with zeroes to make 3 bits if necessary:

011 111 000 011

Convert each group to its equivalent octal digit according to the following table:

000 = 0

001 = 1

010 = 2

011 = 3

100 = 4

101 = 5

110 = 6

111 = 7

Therefore: 011 111 000 011 = 3 7 0 3

Thus: 1987 in octal is 3703.

Proof:

3 * 8^0 = 3

0 * 8^1 = 0

7 * 8^2 = 448

3 * 8^3 = 1536

1536 + 448 + 3 = 1987

Distance vector routing is used when the network is simple and has no hierarchical design. Examples of distance vector routing protocols are RIP and IGRP.
