In this picture,you can see the place which is located in our school where me and my friends usually stay during breaks or free times.I really love this place because I can feel and breath the fresh air that refreshes my mind and relaxed my body if I got tired and stress sometimes from studying.
There,I can see different plants,trees ,flowers and some insectss which fly and fly into the other places.Thats why I will never forget this place,and all the memories that we've shared with my friends if ever I will leave this beloved institution.

Basic networking concepts and technologies.
a. Bandwidth and data transmission
Ø Bandwidth is a term used to describe how much information can be transmitted over a connection. Bandwidth is usually given as bits per second, or as some larger denomination of bits, such as Megabits per second, expressed as kbit/s or Mbit/s. Bandwidth is a gross measurement, taking the total amount of data transferred in a given period of time as a rate, without taking into consideration the quality of the signal itself.

Ø Data transmission means the transportation of information from internet to your computer or sending and receiving data via cables.
b. IP Addressing
Ø Internet Protocol Address (or IP Address) is a unique address that computing devices use to identify itself and communicate with other devices in the Internet Protocol network. Any device connected to the IP network must have a unique IP address within its network. Consists of four numbers, each of which contains one to three digits, with a single dot (.) separating each number or set of digits. Each of the four numbers can range from 0 to 255. Here's an example of what an IP address might look like: 78.125.0.209.
c. (DHCP) Dynamic Host Configuration Protocol
Ø This protocol is used to assign IP addresses to hosts or workstations on the network. Allows a computer to join an IP-based network without having a pre-configured IP address. DHCP is a protocol that assigns unique IP addresses to devices, then releases and renews these addresses as devices leave and re-join the network.
d. Internet Protocol and Application
Ø Specifies the format of packets, also called datagrams, and the addressing scheme .Each IP packet includes both a header (that specifies source, destination, and other information about the data) and the message data itself. Most networks combine IP with a higher-level protocol called Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source.
e. ICMP( Internet Control Message Protocol)
Ø Is one of the core protocols of the Internet Protocol Suite. It is chiefly used by the operating systems of networked computers to send error messages indicating, for example, that a requested service is not available or that a host or router could not be reached. ICMP can also be used to relay query messages.

My Experience as a First Time Blogger
Before,when I heard about the word blog,I really don't have an idea about it.But when someone discussed to me about blog,I'm very excited to have one,because I thought it is enjoyable,exciting and happy to deal with.So when I finally created and have a blog I'm happy and I'm enjoyed.Exciting also for the fact that I can post anything such as; things about myself, my family, school's events,happenings around the world, and I can share some of my knowledge.And I'm glad too,because I know I can learn through blog like how to design my own blog.But maybe sometimes it is hard,but so far blogging for me is fun and enjoyable.
