The chapter also examines different types of computers like PCs, servers, and embedded systems. It describes how computers use layers of abstraction in both hardware and software. The chapter concludes by discussing performance measures like response time and throughput, and how techniques like parallelism can improve performance within power constraints.
A distributed system consists of multiple connected CPUs that appear as a single system to users. Distributed systems provide advantages like communication, resource sharing, reliability and scalability. However, they require distribution-aware software and uninterrupted network connectivity. Distributed operating systems manage resources across connected computers transparently. They provide various forms of transparency and handle issues like failure, concurrency and replication. Remote procedure calls allow calling remote services like local procedures to achieve transparency.
The document provides an overview of computer architecture and input/output techniques. It defines computer architecture as the set of instructions that describe a computer's organization and implementation. It discusses how I/O modules interface external devices like keyboards and printers to the CPU and memory. There are three main I/O techniques: programmed I/O where the CPU directly controls I/O, interrupt-driven I/O where devices interrupt the CPU when ready, and DMA where devices access memory independently of the CPU to improve efficiency. The document outlines the components and functioning of I/O modules and the various I/O commands used to control peripheral devices.
Students with disabilities are those who have physical or mental impairments that substantially limit major life activities like learning. There are 13 categories of disabilities defined by IDEA, including autism, deafness, developmental delays, emotional disturbances, and specific learning disabilities. To qualify for special education services under IDEA, a student's impairment must negatively affect their educational or functional performance compared to peers. General teaching strategies for students with disabilities include presenting information in multiple formats, allowing flexible demonstrations of learning, teaching memory strategies, and adjusting workload and time expectations with a focus on mastery over pace.
A microprocessor is an electronic component that is used by a computer to do its work. It is a central processing unit on a single integrated circuit chip containing millions of very small components including transistors, resistors, and diodes that work together. Some microprocessors in the 20th century required several chips. Microprocessors help to do everything from controlling elevators to searching the Web. Everything a computer does is described by instructions of computer programs, and microprocessors carry out these instructions many millions of times a second. [1]
Microprocessors were invented in the 1970s for use in embedded systems. The majority are still used that way, in such things as mobile phones, cars, military weapons, and home appliances. Some microprocessors are microcontrollers, so small and inexpensive that they are used to control very simple products like flashlights and greeting cards that play music when you open them. A few especially powerful microprocessors are used in personal computers.

The document discusses different types of instruction codes used in computers. It explains that instruction codes contain operation codes and operands. The operation code specifies the operation to be performed, like addition, subtraction, etc. The operands specify the data on which the operation will be performed, which can be stored in memory or registers. The document outlines three main types of instruction codes - memory reference instructions, register reference instructions, and input-output instructions. It describes the format of each type of instruction and how they are interpreted by the computer.
This document discusses arithmetic operations in digital computers, specifically addition and subtraction. It explains how half adders and full adders are implemented using logic gates like XOR and AND-OR to add bits. A ripple carry adder cascades full adder blocks to add multiple bits, while carry lookahead adders reduce delay by computing carry signals in parallel. Binary multiplication is also covered, explaining how a logic array or sequential circuit can multiply numbers by shifting and adding partial products. Booth's algorithm improves on this by recoding the multiplier to reduce operations.
This document discusses input/output organization in computer systems. It describes peripheral devices for input and output, input/output interfaces that allow communication between peripherals and the CPU/memory, and various methods for transferring data asynchronously between independent devices or systems, including strobe control, handshaking, and serial transmission. Asynchronous data transfer is necessary because peripherals often operate at different speeds than the CPU and memory.
This document discusses cache memory organization and characteristics. It begins by describing cache location, capacity, unit of transfer, access methods, and physical characteristics. It then covers the different mapping techniques used in caches, including direct mapping, set associative mapping, and fully associative mapping. The document also discusses cache performance factors like hit ratio, replacement algorithms, write policies, block size, and multilevel cache hierarchies. It provides examples of specific processor cache designs like those used in Intel Pentium processors.
In non-preemptive scheduling once a process has been allocated the CPU it runs uninterrupted until it finishes execution.
On the other hand, in preemptive schedule algorithms, the running process may be interrupted by a higher priority process in between its execution.
Whenever a process gets into ready state or the currently running finishes execution, the priority of the ready state process is checked against that of the running process.
If the priority of the ready process is more it is allowed to be allocated to the CPU.
Therefore, in these schemes, the CPU is allocated to the process with the highest priority all the time.
This gives rise to frequent context switching, which can become very costly in terms of CPU time wasted in switching. In the following sections we will explore some of such scheduling algorithms
Real numbers can be stored using floating point representation, which separates a real number into three parts: a sign bit, exponent, and mantissa. The exponent indicates the power of the base 10 that the mantissa is multiplied by. Common standards like IEEE 754 define single and double precision formats that allocate more bits for higher precision at the cost of range. Summarizing a floating point number involves determining the exponent by shifting the decimal, converting the number to a leading digit mantissa, and writing the sign, exponent, and mantissa based on the specified precision format.
The CPU acts as the computer's brain and carries out instructions from programs. It has two main components: the control unit, which selects and coordinates instruction execution, and the arithmetic logic unit, which performs calculations. Registers temporarily store data during instruction processing, including special purpose registers like the program counter, memory address, and accumulator registers. The CPU communicates with main memory, where files and applications are stored, and executes instructions through a multi-step process controlled by the control unit.

A multimedia database management system (MM-DBMS) manages different types of data in various formats across multiple media sources. Like traditional DBMS, an MM-DBMS provides integration, data independence, concurrency control, persistence, privacy, integrity control, and recovery. Additionally, an MM-DBMS can uniformly query different data formats, simultaneously query across media sources, retrieve media smoothly, and develop presentations from query answers that satisfy quality of service requirements. Multimedia databases support applications like video on demand, medical information systems, and public protection systems, but consume more storage and processing than traditional databases. Current research focuses on high performance and fast partitioning of compressed and uncompressed video.
The document discusses various methods for input/output (IO) in computer systems, including IO interfaces, programmed IO, interrupt-initiated IO, direct memory access (DMA), and input-output processors (IOPs). It describes how each method facilitates the transfer of data between the CPU, memory, and external IO devices.
Modes Of Transfer in Input/Output OrganizationMOHIT AGARWAL
This document discusses different modes of data transfer between I/O devices and memory in a computer system. It describes three main modes: programmed I/O, interrupt-initiated I/O, and direct memory access (DMA). Programmed I/O involves constant CPU monitoring during transfers. Interrupt-initiated I/O uses interrupts to notify the CPU when a transfer is ready. DMA allows I/O devices to access memory directly without CPU involvement for improved efficiency.
The document discusses the four functional units of the CPU: Bus Unit (BU), Instruction Unit (IU), Execution Unit (EU), and Address Unit (AU). It provides details on each unit: the BU performs memory/I/O reads and writes and prefetches instructions into a 6-byte queue; the IU decodes up to three prefetched instructions and holds them in a queue; the EU includes an ALU, registers, and control unit to execute instructions from the IU queue; the AU computes physical addresses for memory/I/O access. It also summarizes key features of the 80286 microprocessor such as supporting 16MB physical memory, 1GB virtual memory using memory management, and operating in real and protected
This document provides an overview of object-oriented databases. It introduces object-oriented programming concepts like encapsulation, polymorphism and inheritance. It then discusses how object-oriented databases combine these concepts with database principles like ACID properties. Advantages include being integrated with programming languages and automatic method storage. Disadvantages include requiring object-oriented programming and high costs to convert data. The document also discusses the Object Query Language and provides an example query in OQL.
RAM allows stored data to be accessed directly in any random order. There are two main types: static RAM and dynamic RAM. Static RAM keeps data without refreshing but is more expensive, while dynamic RAM needs refreshing but is cheaper. RAM is a temporary memory that does not store data permanently once power is turned off. Future RAM technologies aim to provide smaller, faster, and cheaper memory chips compared to today's options like DDR3 RAM.

Her yönüyle linux sistem ve network güvenliğiAhmet Han
Linux, sistem ve network güvenliği üzerine yazmış olduğum çalışmaların bazılarını bu e-book'ta topladım. e-book ile ilgili geri dönüşlerinizi yapabilirsiniz.
Bir Sosyal Sorumluluk Projesi- Kocaeli'de Bulunan Liselere bilgisayar mühendisliğinde kariyer olanakları ile ilgili çalışma
( Bilenler bilmeyenlere yol gösteriyor, bu şekilde diğerleri de öğreniyor.) Doğru Tercih ile Bilgisayar Mühendisliğinde Kariyer
1. SSH Brute Force Saldırıları
Ssh iki cihaz arasında güvenlik kanalıyla veri değişimine imkan sağlayan, izin veren bir network
protokolüdür. Birincil olarak linux ve unix gibi protokollerin kabuk hesaplarına ulaşabilmek için
kullanılmıştır. Telnet gibi güvensiz protokollerin yerini almak amacıyla dizayn edilmiştir.
Telnet protokolü şifresiz bir biçimde veri alışverisinde paralolarınız görülebilecek şekilde
tasarlanmıştır. Ssh protokolü ile veriler şifrelenerek gönderildiği için daha güvenli veri aktarımına
olanak tanımaktadır.
Ssh sunucusu default olarak tcp port 22 üzeriden haberleşme sağlamkatadır. Ssh client - ssh
server arasında gerçekleşen haberleşme sonucu bağlantı kurulmaktadır. Bir çok işletim sistemi
tarafından desteklenmektedir.
ssh bir çok uygulama ile beraber kullanılan bir protokoldür. Bazı uygulamalar sadece ssh serer
ve ssh client programlarına ihtiyaç duyarak çalışırlar. Bu noktada sssh bağlantılarının önemi
büyüktür.
2. ** Port yönlendirme için kullanılabilir.
** Uzak kullanıcı ile kabuğa bağlanılabilmektedir.
** Lokal bilgisayardan uzak bilgisayara dosya gönderilebilmektedir.
** Ftp ile dosya gönderimine alternatif bir güvenlik önlemi sağlanmış olur.
** Openssh ile şifrelenmiş vpn bağlantılarının oluşmasına imkan tanır.
** Uzaktan sunucu kontrolünün sağlanmasına imkan tanımaktadır.
3. ssh protokolünü linux sunucuların yönetimide kullandığımızı daha önce belirtmiştik. Hackerlar
yada sızma testi uzmanları hedef sisteme erişim sağladıklarında root kullanıcı bile olabilirler.
Eğer gerekli önlemler alınmamışsa. Hedef sistem keşif çalışmalarında ya da bilgi toplam
aşamasında ssh prtokolünün sistemede keşfedildiği sırada bu protokole yönelik ssh brute force
(kaba kuvvet) saldırıları deneyebilir. Deneme yanılma saldırıları olarakta adlandırılmaktadırlar.
Temel olarak saldırı işleyiş modeli aşağıdaki şekildeki gibidir.
4. Zayıf şifrelere sahip olduğunuzda rastgele şifreler denenerek brute force saldırıları
gerçekleştirilebilmektedir. İnternette wordlist diye adlandırılan kelime listeleri ile otomatize
araçlar ile brute force saldırıları denenebilmektedir.
Genel olarak brute force saldırıları olsun, ya da ssh brute force saldırıları olsun bu saldrı tipleri
ile ilgili bir çok araç bulunmaktadır.
Hydra, Medusa, Ncrack, Metasploit, HttpBrute gibi daha bir çok farklı saldırı yapmamıza imkan
tanıyan araç bulunmaktadır.
Şimdi örnek bir senaryo ile ssh brute force saldırısını gerçekleştirelim ve bunu tespit edelim.
Lab ortamı için üç farklı dağıtım gerekmektedir.
** Ubuntu Desktop(Saldırı yapılacak sürüm önemli değil)
** Kali linux Atak amaçlı kullanılacak
**Seurity onion saldırı tespit amaçlı
Saldırı işleyiş biçimine gelicek olursak;
Öncelikle vmware sanal makinalarda bulunan dağıtımlarımız aktif edilir. Daha sonra ubuntu
desktop makinamızın ifconfig komutu ile ip adresini öğreniriz. [ 192.168.221.133 ip adresimiz ]
5. Daha sonra kali linux üzerinde bulunan hydra aracı üzerinden şekildeki komut çalıştırılacak
şekilde verilir. Artık kelime listesinde bulunan şifreler denenmektedir.
6. Bu komutal bulamadı. Fakat common.txt dosyası diye bir wordlist olupturup içine yazdığımız
şifreler ile deniyoruz. En sonuna ise gerçek şifremiz 1 değerini yerleştiriyoruz.
Atak gerçekleştirme işlemi başladı. Biraz zaman alıcaktır. Yazdığımız kelime listesine göre ama
şekilden görebilirsiniz. İşlem başarı ile tamamlandı.
Şifrenin 1 olduğunu ve tespit edildiğini gördük. Security onionda aktif olarak çalışan snort ise bu
durumu tespit etmiştir. snorby arayüzdende yapılan bu atakla ilgili düşen logları görmek
mümkündür. Saldırının yapıldığı kaynak ve hedef ip adresi tespit edilmiştir.
