Answer:

Voltage spike – This is a momentary change in the supply of electric power. It’s important to remember that the size of the transient can range from just milliseconds to longer periods of time. Even a small power glitch can damage a computer and corrupt data. If the screen goes blank during a thunderstorm, it’s likely that a voltage spike is responsible.

Circuit board fails with no visible indication of damage – This is the typical scenario: A computer goes down. A defective circuit board is suspected of the fault, but an inspection reveals no signs of physical damage. A replacement board is installed and operation resumes.

Failure to load software upgrades – Computer software often comes with various bugs, or vulnerabilities. These are simply programming mistakes, but they can make the software susceptible to viruses and glitches. When an error is discovered, the software designer sends out a “patch” that requires downloading and rebooting. Failing to upgrade the software by running the patch can lead to corruption of data.

Failure to keep virus protection up to date – There are several malware protection packages available for computer rooms or data centers. Once installed, the subscription must be maintained. One telltale sign of a malware infected computer is slow data processing.

Inadequate cooling – Computers produce heat, and the more data they process, the more heat must be eliminated. Servers, the “brains” of computers, fail under excess heat, so adequate cooling is essential.

Environment – If a computer room has a dedicated cooling system, there may be an opportunity to closely control the heat. If the cooling is shared with other equipment or the space contains offices, we often face a more challenging task. People have comfort needs different to those of computers.

Loss of Power, PDU fails – Power Distribution Units (PDU’s) are similar to power bars in homes and offices. They distribute power to different components in a computer room, and are usually located next to the server racks. PDU’s suffer a range of problems. Receptacles wear out and can be the sources of bad contacts, and moisture can lead to corrosion.

UPS batteries – Uninterruptible Power Supply (UPS) batteries are found in computer rooms. Most often, they are used to provide continuous power for a limited time, during an outage. Depending on how it’s used and the design of the battery, the life span can be as short as 4-5 years for what is considered a “10 year life” battery. Elevated room temperatures will shorten the life of any battery. Even a small facility such as a dentist office uses UPS batteries.

Transfer switch battery defective – This can be an indication that the site lacks an effective battery maintenance program. It can also be a sign that the transfer switch is “frozen” in position. Preventive maintenance could help avoid a breakdown.

Failure of standby power to synchronize (come on line) – When electric power from the grid disappears, standby power takes over in two different ways. In a small computer room, the focus is on turning computers off in a controlled manner. A fully charged UPS will provide power for 10-15 minutes to allow a computer to save its data and turn off. In a larger facility, it’s the matter of keeping cooling and power going long enough to give the standby generator an opportunity to “synchronize,” to get up to a rate of speed sufficient to power the infrastructure and continue data processing.

Diesel fuel contaminated – Most medium to large facilities have generators powered by diesel fuel, which can become contaminated and useless when a power outage occurs. Water is usually the culprit. Regular fuel testing is necessary to avoid contamination.

Storage defective – Data is stored on magnetic disks or tape. Both can be damaged during normal operation, so it’s a good practice to back up stored data on a regular basis. Backing up means creating a spare data storage. Failure of a tape or disk drive is often, but not always, proceeded by noise. Opening the unit to attempt data restoration is better left to a professional.

Sprinkler system turns on above the servers – Where a data room is protected by a water sprinkler system, a small spill can damage the electronic components. This is particularly true in cases where sprinkler heads are located directly above the servers.

Computers are crucial to business today, but there are so many things that can cause them to fail. By addressing the above common culprits, you could help reduce the overall risk of your computer systems failing.

Answer:

If there’s one topic that trips people up (both new and experienced) in the networking industry, it is that of Subnetting.

One of the reasons this happens is that one has to perform (mental) calculations in decimal and also binary. Another reason is that many people have not had enough practice with subnetting.

In this article, we will discuss what Subnetting is, why it came about, its usefulness, and how to do subnetting the proper way. To make this article as practical as possible, we will go through many examples.

Note: While subnetting applies to both IPv4 and IPv6, this article will only focus on IPv4. The same concepts explained here can be applied to IPv6. Moreover, subnetting in IPv6 is more of a want rather than a necessity because of the large address space.

IP address network

For example, any traffic with a destination IP address of 192.168.1.101 will be delivered to PC1, while traffic addressed to 192.168.1.250 will be delivered to SERVER.

Note: This is an oversimplification of things just for understanding sake and refers to Unicast (one-to-one) IPv4 addresses. Traffic sent to Multicast (one-to-many) and Broadcast (one-to-all) IP addresses can be delivered to multiple devices. Also, features like Network Address Translation (NAT) allow one IP address to be shared by multiple devices.

To help your understanding of IP addresses and subnetting, you need to resolve the following fact in your head: Computers think in binary, that is, 0s and 1s. Therefore, even though we see an IP address represented like 192.168.1.250, it is actually just a string of bits – 32 bits in total for IPv4 addresses.

To make them more readable for humans, IPv4 addresses are represented in dotted decimal notation where the 32 bits are divided into 4 blocks of 8 bits (also known as an octet), and each block is converted to a decimal number.

For example, 01110100 in binary is 116 in decimal:

A unicast IPv4 address such as 192.168.1.250 can be divided into two parts: Network portion and Host ID. So what does this mean? Well, IPv4 addresses were originally designed based on classes: Class A to Class E. Multicast addresses are assigned from the Class D range while Class E is reserved for experimental use, leaving us with Class A to C:

Class A: Uses the first 8 bits for the Network portion leaving 24 bits for host IDs. The leftmost bit is set to “0”.

Class B: Uses the first 16 bits for the Network portion leaving 16 bits for host IDs. The two leftmost bits are set to “10”.

Class C: Uses the first 24 bits for the Network portion leaving 8 bits for host IDs. The three leftmost bits are set to “110”.

Note: The range of Class A is actually 1-126 because 0.x.x.x and 127.x.x.x are reserved.

With these classes, a computer/device can look at the first three bits of any IP address and determine what class it belongs to. For example, the 192.168.1.250 IP address clearly falls into the Class C range.

Looking at the Host ID portion of the classes, we can determine how many hosts (or number of individual IP addresses) a network in each class will support. For example, a Class C network will ideally support up to 256 host IDs i.e. from 00000000 (decimal 0) to 11111111 (decimal 255). However, two of these addresses cannot be assigned to hosts because the first (all 0s) represents the network address while the last (all 1s) represents the broadcast address. This leaves us with 254 host IDs. A simple formula to calculate the number of hosts supported

Explanation: Final answer is Start address: 192.168.58.0 + 1 = 192.168.58.1

End address: 192.168.58.16 – 2 = 192.168.58.14

Broadcast address: 192.168.58.16 – 1 = 192.168.58.15

The program in python is as follows:

for i in range(0,6):

   for i in range(0,9):

       print(" ",end='')

   print("|",end='')

print()

for i in range(1,61):

   print(i%10,end='')

Explanation:

See attachment for program output format

The next two instructions create a nested for loop

for i in range(0,6):

   for i in range(0,9):

This prints 9 spaces

       print(" ",end='')

This prints a vertical line at the top of the end of the spaces printed

   print("|",end='')

This prints a new line

print()

This iterates from 1 to 60

for i in range(1,61):

This prints 1, 2, 3....9, then 0, 6 times on a straight line

   print(i%10,end='')

D. Chain and Sprockets

Explanation:

Chains and sprockets are power transmission tools. The roller chain is connected to a toothed wheel which is the sprocket. The combination provides mechanical power to the wheels of vehicles.

An advantage they possess is their ability to transmit mechanical power over both short and long distances. They have a high degree of efficiency but they require constant lubrication. They also produce noise during operation.
