Many think that the computer is less competent if given at an early age children, because it is difficult for those hard to reach a more concrete stage of thinking. But pnelitian show that at age 3 to 4 years old have a high sense of creativity and can be applied in the computer, if supported by appropriate educational soft ware, for example, LoGa kompiuter which is a language designed specifically as a learning environment. The kids write the programs that create an image through the command transfer "turtle" a small pointer on the screen. This type of productive activity can improve learning and creativity.

EFFECT OF COMPUTER FOR KIDS

CHARACTERISTICS OF CHILDREN?? Age and experience affect the child's social interaction. Interestingly the pattern of development appears both at the level of development from the youngest to the oldest as well as with experience in computer environment
such as logos.
Patterns include egocentric focus, followed by the orientation of peers in helping and teaching and ultimately cooperate with peers and independent of adult guidance.
     
      Individual differences also have an impact on social interaction. For example, children with high ability to act more dominant in group work with computers and are more likely to use in competitive interactions dengfan kompettitif software. Low-less-capable students who contribute to the cooperative computer activities and more likely to be scorned peers in a competitive situation.

Teacher Role?? Factors affecting teachers lingkungaKehadiran child interaction. Teachers facilitate the exchange of places and teach their peers through a set of environmental education. The biggest relief is to encourage children to use computers in pairs, pair the child allows them to work berssama well, pushing kooperatif.n very important is the role played by teachers.

Selain alamat IP, sistem jaringan operasi beberapa menggunakan nama. Dalam lingkungan ini setiap sistem individu harus memiliki nama yang unik yang ditugaskan untuk itu.

Sebuah nama komputer memberikan nama user friendly, sehingga memudahkan pengguna untuk terhubung ke sumber daya bersama, misalnya folder dan printer di komputer lain.

Administrator jaringan harus menentukan skema penamaan logis yang membantu untuk mengidentifikasi jenis perangkat dan / atau lokasinya. Sebagai contoh, nama PRT-CL-Eng-01 dapat mewakili laser printer berwarna pertama di Jurusan Teknik.

Nama-nama ini secara manual ditugaskan untuk setiap perangkat, meskipun beberapa alat memang ada untuk membantu mengotomatisasi proses penamaan. Deskripsi komputer juga dapat dimasukkan ketika menetapkan nama untuk memberikan informasi tambahan tentang lokasi atau fungsi dari perangkat.

Definisi: Object Oriented Programming (OOP) adalah sebuah metode pengembangan perangkat lunak yang model dunia nyata menggunakan obyek. Misalnya simulasi mengemudi mungkin memiliki objek jalan, kendaraan dan mungkin benda benda manusia.

Sebuah objek adalah barang yang lengkap data yang hanya dapat diakses atau diubah dalam cara yang terkontrol. Hal ini mencegah efek samping-masalah umum dalam prosedural (non objek) kode dimana data diakses secara global. Objek dapat menerima atau mengirim pesan ke objek lain dengan memanggil metode mereka.

Objek dapat didefinisikan dalam hal obyek yang sudah ada-ini dikenal sebagai warisan. Untuk melihat mendalam di OOP, lihat artikel tentang Pemrograman Berorientasi Objek.

SCHEDULING PROCESS
• A set of policies and mechanisms on the Operating System with respect to the order of the work done    Computer Systems.
• In charge of deciding who should run the process, when and for how long the process runs.
• Goal à ..!!! PERFORMANCE OPTIMIZATION

CRITERIA SCHEDULING PROCESS

1. FAIR (Fairness)
      Fair is where the processes are treated the same which gets a small processor and the same time there is no process that gets no processing services.
      Target scheduling is to ensure every process gets a fair part of the processing.

 

2. EFFICIENCY (CPU Utilization)

      Scheduling keep the unused processor continuously as long as there is an active process in the queue ready, generally proses2 waiting user input or I / O operations will be blocked and Blocked status, so that did not participate in the scheduling process.

      Target processor scheduling is to keep busy in order to remain in a state so that maximum efficiency. Busy refers to the processor is not idle, including the time spent to execute user programs and SO.

3. RESPONSE TIME (Response Time) Response time in interactive systems is the duration of time between the user provides input to the operating system to provide output or feedback to users, Target scheduling is to minimize response time.

4. WAITING TIME (Waiting Time) Represents a duration of time spent in the queue ready prses during their life cycle. In general, a good scheduling algorithm produces an average waiting time is small for the entire process .

5. ARROUND TURN TIME (TA) Turn Arround Time is the time spent from when the program or job started to get into the system until the process is completed the system. Represents the sum of the duration of the execution process (running) with a duration of waiting (waiting).

Turn Arround Time:
Old Execution + Waiting Time
or
Done Execution - Time Arrives  

6. Throughput

    Throughput is the average process can be completed per unit time

The way to express the throughput is the number of user jobs that can be executed in one unit / time interval.

     schedule goal is to maximize the number of jobs that are processed at a time interval. Higher throughput rate, the more work done by the system.

Throughput: S TA / S process

Definition detail : A local area network (LAN) supplies networking capability to a group of computers in close proximity to each other such as in an office building, a school, or a home. A LAN is useful for sharing resources like files, printers, games or other applications. A LAN in turn often connects to other LANs, and to the Internet or other WAN. 


Most local area networks are built with relatively inexpensive hardware such as Ethernet cables, network adapters, and hubs. Wireless LAN and other more advanced LAN hardware options also exist.

Specialized operating system software may be used to configure a local area network. For example, most flavors of Microsoft Windows provide a software package called Internet Connection Sharing (ICS) that supports controlled access to LAN resources.
The term LAN party refers to a multiplayer gaming event where participants bring their own computers and build a temporary LAN.


Also Known As: local area network
Examples:
The most common type of local area network is an Ethernet LAN. The smallest home LAN can have exactly two computers; a large LAN can accommodate many thousands of computers. Many LANs are divided into logical groups called subnets. An Internet Protocol (IP) "Class A" LAN can in theory accommodate more than 16 million devices organized into subnets.

Benefits include:

· Used to connect multiple computers located within the building / office.
· LAN network called the local network.
· file servers to provide software services to manage the network and store data.
· topology used for the LAN network is a ring topology and bus topology.

Represents:

     * Scheduling of the oldest, simple, fair, widely used and easily implemented algorithm.
     * Scheduling is not dipreempt by another process but by the scheduler based on the long running process       (preempt by time).
     * Scheduling without priority.
     * Assume that all processes have the same interests, so there is no particular priority.

All processes are considered important so that the given amount of time the processor is called kwanta (quantum) or time slice, where the process is running. If the process is still running until the end of the quantum, the CPU will mempreempt process and gives them to other processes.

 

Scheduler needs to maintain a list of runnable processes. When the quantum is exhausted for a particular process, the process will be placed at the end of the list (list), as apparent in the following picture:

 Terms of round robin algorithm is as follows:
1. If the quantum and the process was not completed then the process becomes runnable and processing is transferred to another process.
2. If the quantum has not been exhausted and the process of waiting for an event (the completion of I / O), then the process becomes blocked and the processor is transferred to another process.
  3. If the quantum has not been exhausted but the process has been completed, then the process is terminated and processing is transferred to another process.

Scheduling this:
a. Good for interactive-time sharing system where most of the time used to wait for external events.
Examples: text editors, most of the time the program is to wait for the keyboard, so it can run other processes.
b. Not suitable for real time systems let alone the hard-real-time applications.
