VARIOUS TYPES OF CABLES

VARIOUS TYPES OF CABLES 


HDD AND FDD CABLE: 
The most common form of HDD cable is 40 Pin IDE cable having 40 wires. A standard IDE cable is a flat ribbon cable, normally gray in color, with a (usually red) stripe running down the edge. The cable has 40 wire connectors in it, and usually has three identical female connectors: one is intended for  the IDE controller (or motherboard header for PCs) and the other two are for the master and slave devices on the interface.Another standard is 80 wire 40 pin IDE cable which are compatible with 40 wire IDE 
cables. The extra 40 wires are used to reduce the interference.For connection of FDD 34 wires FDD cable is used. The FDD as shown in fig 10.24. 

SCSI CABLE 
This cable is used to connect the SCSI device to the SCSI controller. This cable is commonly a wide flat cable however may also be a rounded cable. SCSI cables often have multiple connections on a single cable allowing multiple devices to connect to a single controller.dozens of different types of cables.cables are usually ribbon cables multiple 68 pin or 50 pin connectors. External cables are shielded and only have connectors on the ends. 

    SCSI is different from most PC interfaces in that it supports both internal and external devices. These use drastically different types of cabling, because the environment inside the PC is very different from that outside it. Both internal and external cable come in a variety of styles themselves. some examples are: Twisted pair Wiring, Shielding, and layered structure. 

SMART CABLE 
Also known as an intelligent cable, a smart cable is a cable that contains built-in circuitry to detect the type of transmission and be able to convert it to another type of transmission. Smart cables may also be a type of cable that converts from one standard into another. For example a cable as shown in fig. that allows a SCSI device to work through USB. 
 
USB CABLE 
These USB cables may be used for USB mouse or keyboard cables, USB printers or any other standard USB devices. The maximum speed of USB 2.0 standard is 480 Mbps. For fig and detailed description please refer to USB port in this chapter. 

RCA CABLE
The RCA jack uses 75 Ω coaxial cable which are used to transfer Composite video along with stereo audio in three RCA cables. It is also used in S/PDIF interface, component video etc. 

    The name "RCA" derives from the Radio Corporation of America, which introduced the design by 
the early 1940s to allow mono phonograph players to be connected to amplifiers.

SATA 
    SATA hard-drive technology is based on serial data processing, which means that information traveling from the drive to the data bus is clocked and sent in an orderly fashion. 

     The SATA cables have 6 pin connectors at both ends and there may be 2, 4 or even more SATA connectors provided on the motherboard and each cable connects to a HDD. Connecting more than one 
HDD by SATA does not require any jumper setting for master and slave configuration. SATA hard drives use thin ribbon cables which are a pleasure to work with. The slender cables have "clip on" connectors, which are simple to work with, even in the most cramped corners of the PC case.

PATA 
    AT Attachment (ATA) and AT Attachment Packet Interface (ATAPI) are interface standards for the connection of storage devices such as hard disks, solid-state drives, and CD-ROM drives in computers.
 
    The current ATA/ATAPI standard is the result of a long history of incremental technical development. ATA/ATAPI is an evolution of the AT Attachment Interface, which was itself evolved in several stages from Western Digital's original Integrated Drive Electronics interface. As a result, many 
near-synonyms for ATA/ATAPI and its previous incarnations exist, including abbreviations such as IDE
which are still in common informal use. With the market introduction of Serial ATA in 2003, the original ATA was retroactively renamed Parallel ATA (PATA). 

HDMI
    HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting 
uncompressed digital data. It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable, composite video, S-Video, component video, and VGA. HDMI connects digital audio/video sources such as set-top boxes, Blu-ray Disc players, personal computers (PCs), video game consoles, and AV receivers to compatible digital audio devices, computer monitors, and digital televisions. 

    HDMI supports, on a single cable, any TV or PC video format, including standard, enhanced, and high-definition video, up to 8 channels of digital audio, and the Consumer Electronics Control signal. A Digital Visual Interface (DVI) signal is electrically compatible with an HDMI video signal; no signal conversion needs to take place when an adapter is used, and consequently no loss in video quality 
occurs. 

    HDMI devices are manufactured to adhere to various versions of the specification, where each version is given a number such as 1.0, 1.2, or 1.3a. Each subsequent version of the specification uses the same kind of cable but increases the bandwidth and/or capabilities of what can be transmitted over the cable. For example the previous maximum pixel clock rate of HDMI interface was 165 MHz which was sufficient for supporting WUXGA (1920x1200) at 60 Hz. HDMI 1.3 increased that to 340 MHz which allows for higher resolution, such as WQXGA (2560x1600), across a single digital link.

BIOS

BIOS       BIOS is a software which resides in a small flash EEPROM memory on the motherboard. It is a  form of read only memory (ROM), but may be rewritten or programmed when the right tools and  techniques are applied. It works as an interface between the computer hardware and operating system  and communicates between computer and devices.       The BIOS is very important part of your computer that makes its home on the motherboard. The BIOS provides an interface between the raw PC hardware and the standard operating system, it is usually stored in ROM. As you can see, BIOS is important; every computer needs it. And like CPU's, it comes in different versions. BIOS versions are based on years. These chips are typically the biggest chips on your motherboard other than the CPU and math-coprocessor. There is usually a big sticker on it that says BIOS. The sticker also says what kind of BIOS it is and what year the BIOS were published...

ईथरनेट शब्दावली /Ethernet Terminology

           ईथरनेट   शब्दावली   ईथरनेट नियमों के एक सरल सेट का अनुसरण करता है जो इसके मूल संचालन को नियंत्रित करता है। इन नियमों को बेहतर ढंग से समझने के लिए, ईथरनेट शब्दावली की मूल बातें समझना महत्वपूर्ण है।  मध्यम   (Medium) ईथरनेट डिवाइस एक सामान्य माध्यम से जुड़ते हैं जो एक रास्ता प्रदान करता है जिसके साथ इलेक्ट्रॉनिक सिग्नल यात्रा करेंगे। ऐतिहासिक रूप से, यह माध्यम समाक्षीय तांबा केबल रहा है, लेकिन आज यह अधिक सामान्यतः एक मुड़ जोड़ी या फाइबर ऑप्टिक केबलिंग है।   खंड ( Segment ) हम ईथरनेट खंड के रूप में एकल साझा माध्यम का उल्लेख करते हैं। नोड डिवाइस जो उस सेगमेंट से जुड़ते हैं वे स्टेशन या नोड होते हैं। ढांचा नोड्स छोटे संदेशों में कहे जाते हैं, जिन्हें फ्रेम कहा जाता है, जो सूचनाओं के भिन्न आकार होते हैं।  फ़्रेम ( Frame )  मानव भाषा में वाक्यों के अनुरूप हैं। अंग्रेजी में, हमारे वाक्य बनाने के नियम हैं: हम जानते हैं कि प्रत्येक वाक्य में एक विषय और एक विधेय होना चाहिए। ईथरनेट प्रोटोकॉल फ्रेम के निर्माण के लिए नियमों क...

Ethernet/ईथरनेट

         ईथरनेट (Ethernet)  ईथरनेट एक ऐसा प्रोटोकॉल है जो सभी डिवाइसों को सभी साझा किए गए एकल केबल की मदद से नेटवर्क पर अन्य सभी उपकरणों के साथ संचार करने में सक्षम बनाता है। यह मूल रूप से दो सरल पर काम करता है प्रधान अध्यापक:- 1. एक निश्चित समय पर केवल एक उपकरण संचारित होगा और बाकी सभी वाहक के सुनने में होंगे। पैकेट सभी को भेजा जाएगा लेकिन केवल सही नोड द्वारा प्राप्त किया जाएगा। बाकी सभी नोड इस पैकेट को अस्वीकार कर देंगे। एक बार पैकेट को अग्रेषित करने के बाद अगला उपकरण समाप्त हो जाएगा और अन्य सभी सुनने में होंगे। 2. यदि दो डिवाइस एक ही समय में अग्रेषित करना शुरू करते हैं तो पैकेट की टक्कर होगी और संवेदन के बाद दोनों उपकरण प्रसारण बंद कर देंगे और फिर से एक-एक करके प्रसारण शुरू कर देंगे।   1973 में, ज़ेरॉक्स कॉरपोरेशन के पालो ऑल्टो रिसर्च सेंटर (जिसे आमतौर पर PARC के रूप में जाना जाता है) में, शोधकर्ता बॉब मेटकाफ ने पहले ईथरनेट नेटवर्क का डिजाइन और परीक्षण किया। ज़ेरॉक्स के "ऑल्टो" कंप्यूटर को प्रिंटर से लिंक करने के तरीके पर काम करते समय, मेटकाफ ने केब...

TYPES OF RAM AND ROM

TYPES OF RAM AND ROM  Common RAM Types  • SRAM       Static random access memory uses multiple transistors, typically four to six, for each memory cell  but doesn't have a capacitor in each cell. It is used primarily for cache. These types of memory are physically bulky and somewhat limited to its capacity.       In Static RAM, a form of flip-flop holds each bit of memory. A flip-flop for a memory cell takes four or six transistors along with some wiring, but never has to be refreshed. This makes static RAM significantly faster than dynamic RAM. However, because it has more parts, a static memory cell takes up a lot more space on a chip than a dynamic memory cell. Therefore, you get less memory per chip, and that makes static RAM a lot more expensive      Static RAM is fast and expensive, and dynamic RAM is less expensive and slower. Static RAM is  used to create the CPU's speed-sensitive cache, while dynamic RAM...
