Uninterruptible power supply (UPS)

An Uninterruptible power supply (UPS), also known as a battery back-up, provides emergency power and, depending on the topology, line regulation as well to connected equipment by supplying power from a separate source when utility power is not available. It differs from an auxiliary or emergency power system or standby generator, which does not provide instant protection from a momentary power interruption. A UPS, however, can be used to provide uninterrupted power to equipment, typically for 5–15 minutes until an auxiliary power supply can be turned on, utility power restored, or equipment safely shut down.

Meaning Of KEYLOGGER

Keylogger is a top-rated, invisible and easy-to-use surveillance tool that records every keystroke to a log file. The log file can be sent secretly with email or File Transfer Protocol (FTP) to a specified receiver. Keylogger can also detection specified keywords and take a screenshot whenever one is typed, displaying findings in a tidy log viewer. It causes no suspicious slowdowns and takes very few system resources. all this is happening in full stealth mode so the person you are monitoring will never be aware of it.

The keylogger automatically activates itself when windows starts and doesn't appear in the 'Task Manager' when CTRL-ALT-DEL is pressed.All In One Keylogger has a very comprehensive Log Viewer. It allows you to aspect, browse, delete, check and filter your log files.All In One Keylogger allows you to view logs by dates or by viewing the total log.You can set the Log Viewer to mark only dates when logs were registered.It also supports HTML reports.

NA (Network Address) Segment 5
192.168.4.40

BA (Broadcast Address) Segment 5
192.168.4.47

Rumus n Contoh

NA = Bil Host x (Segment - 1) NA = Network Address

BA = NA + (Bil. Host - 1 ) BA = Broadcast Address

Contoh :
192.168.5.0/27 Bil Host = 32 Segment = 7

NA = 32 x (7 - 1)
= 32 x 6
= 192 (192.168.5.192)

BA = 192 + (32 - 1)
= 192 + 31
= 223 (192.168.5.223)

Example Of Subnetting

192.168.5.0/xx 7 Segment

Meaning Of Network Address n Broadcast Address

Network Address
- identify the subnet of a host

Broadcast Address
- An IP address that allows information to be send to all machine on a given subnet rather than a specific machine

Exercises

0 - network address
255 - Broadcast address
1 - 254 - valid IP

EXAMPLE
1. 192.3.2.2 - valid Class C
2. 211.255.254.2 - invalid (it because 255 is broadcast address)
3. 0.1.1.0 - invalid (It because 0 can't at 1st octac)
4. 7.4.5.1 - valid class A
5. 127.0.0.1 - invalid (It because 127 not in class)

IP Address Note

IP (Internet Protocol), to communicate from PC to PC or Internet.
Class A : 1-126 (Range of ip address)
Class B : 128-191 (Range of ip address)
Class C : 192-223 (Range of ip address)
Class D : 224-239 (NumHicasting)
Class F : 240-254 (Reserve IP)
Catogories of IP Address:
*Static- Automatically define by network domain.
*Dynamic- Setting sendiri, selalunya dari router.

Subnetting

Subnetting is used to break the network into smaller more efficient subnets to prevent excessive rates of Ethernet packet collision in a large network. Such subnets can be arranged hierarchically, with the organization's network address space (see also Autonomous System) partitioned into a tree-like structure. Routers are used to manage traffic and constitute borders between subnets.

IP Address

- communicate from PC to PC @ Internet

An Internet Protocol (IP) address is a numerical identification and logical address that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes.[1] Although IP addresses are stored as binary numbers, they are usually displayed in human-readable notations, such as 208.77.188.166 (for IPv4), and 2001:db8:0:1234:0:567:1:1 (for IPv6). The role of the IP address has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there."[2]
